Welcome to the Keratoconus Center

"This website was designed to provide the latest information about treatments and research for patients with keratoconus. For 35 years, we have dedicated much of our professional life to studying keratoconus and treating patients in the hope that those with keratoconus may benefit from our extensive clinical experience. We have been leaders in the research, study and advancement of Corneal Cross-Linking (CXL) and have presented our results nationally and internationally. Currently, we have an FDA trial allowing us to treat children as young as age 10 with keratoconus. We have been performing CXL in adults since 2009 with excellent results."

"Many patients with keratoconus feel their treatment options are limited, this is not correct. Two new treatments for keratoconus are INTACS with the Intralase and Corneal Transplants with the laser (I.E.K.) both provide a safe and effective means to obtain excellent vision in keratoconus patients who can no longer tolerate their contact lenses"


What is Keratoconus?

The cornea is the window of the eye. Light travels through the cornea past the lens to the retina and then the brain to form a visual image. The normal corneal surface is smooth and aspheric i.e. round in the center, flattening towards its outer edges. Light rays passing through it moves in an undistorted manner to the retina to project a clear image to the brain.

In patients with keratoconus the cornea is cone shaped (hence the name keratoconus, derived from the greek word for cornea (‘kerato’) and cone shaped (‘conus’). In patients with keratoconus the cornea is not only cone shaped but the surface is also irregular resulting in a distorted image being projected onto the brain.

Because the cornea is irregular and cone shaped, glasses do not adequately correct the vision in patients with keratoconus since they cannot conform to the shape of the eye. Patients with keratoconus see best with rigid contact lenses since these lenses provide a clear surface in front of the cornea allowing the light rays to be projected clearly to the retina. Hence the vast majority of patients are treated with rigid contact lenses. There are however some excellent new surgical options for patients with keratoconus who cannot tolerate these lenses, these options are discussed under treatments for keratoconus.

Many patients are initially unaware they have keratoconus and see their eye doctor because of increasing spectacle blur or progressive changes in their prescription. In many instances even a good refraction yields poor vision. Keratoconus is most often diagnosed by a cornea specialist who may see typical findings when examining the patient at the slit-lamp. In early forms of the disease there may be no obvious finding on slit-lamp evaluation and the diagnosis is made by computerized videokeratography only.

Keratoconus typically commences at puberty and progresses to the mid thirties at which time progression slows and often stops. Between age 12 and 35 it can arrest or progress at any time and there is now way to predict how fast it will progress or if it will progress at all. In general young patients with advanced disease are more likely to progress to the point where they may ultimately require some form of surgical intervention.

 Keratoconus may occur in one eye only initially but most commonly affects both eyes with one eye being more severely affected than the other. Both males and females are equally affected and there is no ethnic predilection though in some parts of the world such as New Zealand and in certain parts of Finland there is a higher incidence due to genetic factors.

Despite millions of dollars being spent on keratoconus no one truly knows the cause of the disease. There have been many interesting theories but none of them have been proven conclusively neither have any of them consistently been reproduced by multiple research groups. For example one theory suggests that there is deficient collagen crosslinking caused by free radicals but there is no scientific reproducible evidence to support such a theory. Others suggest that eye rubbing causes the progression of keratoconus. The evidence for this is however anecdotal based on several case reports, but again there is no reproducible scientific evidence to support this.

Our research group was the first group to demonstrate that genetic factors play a major role in the development of keratoconus. While our scientific based evidence supports a role for genetic factors this does not mean if your children will necessarily develop keratoconus, since only 13-15% of keratoconus patients have a family history with keratoconus. It does mean however that genes play a role in its development and understanding their role in the development of keratoconus may one day lead to a permanent cure.

Keratoconus Research Overview

The Keratoconus Center is proud to offer more clinical trials for both treatment and understanding the basis of this disease than any other center in the world. Our clinical trials include:

  • The early treatment of keratoconus with INTACS and the Intralase laser.
  • Identifying genes in families with keratoconus.
  • PRK (photorefractive keratectomy) for keratoconus.
  • Treatment of mild to moderate keratoconus with INTACS and the Intralase laser.
  • Treatment of keratoconus with the Visian ICL.
  • Lamellar transplants in the treatment of  keratoconus.
  • Developing a molecular genetic test to diagnose keratoconus.
  • Videokeratography indices for detecting early keratoconus.

To date our research has significant contribution to the medical understanding, advances, and treatment of keratoconus. Our achievements include:

  • Developed a computer software to early detect keratoconus.
  • Identified the first molecular defect in keratoconus.
  • The first group to demonstrate keratoconus has a genetic basis.
  • The first group to publish and demonstrate that inserting INTACS with the Intralase laser is safer and more accurate than the mechanical technique.
  • The first group in Los Angeles to offer the Intralase laser for corneal transplants in patients with keratoconus.

Clinical Research

Videokeratography Indices for Detecting ‘Early’ Keratoconus
Our center is a large referral center for patients who are suspected for having keratoconus with either suspicious topography or clinical signs. We see approximately 20 such consults each week. We have developed computerized software with indices, which are critical in helping us make a decision as to whether it is safe to recommend patients proceed with laser refractive surgery. Development of this software has been dependant on developing a large database of normal patients and patients with suspected ‘early’ disease’ and following such patients longitudinally over time. Data from all patients who visit us for referral are entered into databases for ongoing evaluation and refinement of these indices.

Treatment Options for Keratoconus


Patients with very mild disease may initially be corrected with glasses or soft contact lenses, however the vast majority of patients need rigid contact lenses for adequate vision correction. There are a variety of types of specialized rigid contact lenses and depending on the contact lens fitters experience or expertise they will describe the one best suited for you. The very latest contact lens for treating keratoconus is the  “synergize hybrid contact lens”  which is rigid in the middle and soft on the edges. This has the potential to give you the good quality vision of the rigid lens with some of the comforts of the soft lens.  We don’t fit contact lenses, but we do work with several excellent optometrists who specialize in fitting lenses for keratoconus in the Los Angeles area and would be happy to refer you to one should you so desire. It is always a good idea to try several different contact lenses and fitters before giving up on them and embarking on surgery.

Many patients find their contact lenses uncomfortable and can only tolerate their contact lenses for a short period of time. The reason this happens is that the cornea steepens and rubs against the lens causing an abrasion and light sensitivity .
 Another reason is patients with keratoconus often have very dry eye and as the eye dries out there is no lubricating barrier between the lens and the cornea contributing to the patient being uncomfortable. There are now many ways to treat dry eyes to improve contact lens tolerance. This includes the use of artificial tears, treating the lids for lid disease, Restasis– for increasing tear production and the use of punctal  plugs to prevent tears from draining down your nasolacrimal ducts and keeping the eye moist.

Sometimes a little scar or nebulous appears on the tip of the cornea that constantly rubs against the lens making it difficult to tolerate  contact lenses, this scar can be removed with a blade or with the Excimer laser to return patients to contact lens tolerance – this procedure is called phototherapeutic keratectomy(PTK) or nebulectomy.


A method for flattening the cornea that is too steep and making a patient more contact lens tolerant is the insertion of  INTACS into the cornea. This procedure is good for patients who are contact lens intolerant and who want to avoid a corneal transplant and whose K readings are not in excess of  58 Diopters. It is also useful for individuals with keratoconus who want to improve their present vision with or without contact lenses.  This technique involves the insertion of two arc like plastic segments into the middle of the cornea to flatten the cornea. This procedure was pioneered 8 years ago in France, and is routinely being done by many cornea specialists in the United States. It is FDA approved under an IDE protocol and many insurances cover all or part of the cost. Our center pioneered the use of the Intralase  laser for making the channels to insert the plastic segments this makes it a much safer and simpler technique for the patient compared to the mechanical technique which involves using metal blades, our finding have been confirmed by several other large research groups.  We have now done several hundred of these procedures with the Intralase with excellent results.  In many instances we have had to remove INTACS that were too superficially placed elsewhere using the mechanical technique only to get an excellent result when it is inserted with the safer and more accurate  Intralase technique.

COLLAGEN CROSSLINKING (CXL) – to stop the progression of Keratoconus. Click below to view an educational video about the procedure.

The most promising technology for treating Keratoconus called collagen cross linking (CXL) with UVA is currently being introduced into the United States under experimental protocols in Clinical Trials. This treatment, which has been used in Europe for eight years, now is undergoing Phase 1 FDA clinical trials in the United States. It has been demonstrated to be safe and effective if performed, with the epithelium removed, and has the potential to stop the progression of Keratoconus. This treatment is recommended for individuals with progressive Keratoconus or Ectasia following LASIK to stabilize the cornea. It can be performed with our without INTACS. Even though enrollment for this procedure for the FDA trials is closed, our center is one of the only centers in the United States that has received and I.D.E. (Investigational Device Exemption) from the FDA to treat patients with this procedure and we are currently enrolling patients under an Investigational protocol.

This protocol allows us to enroll patients for the next 5 years and can be viewed on the government website – Since this treatment is still regarded as experimental in the United States it should only be done with Institutional Review Board (IRB) approval, so that patients can adequately be protected.

The procedure, which is painless, is as follows. The top layer of the cornea is removed under local anesthesia. Vitamin drops are soaked into the cornea until they penetrate the entire corneal and evidence of penetration into the anterior chamber of the eye is demonstrated by slit-lamp evaluation. Once this is confirmed the patient’s eye is put under a specialized lamp, which emits UV light at a predetermined wavelength for approximately 30 minutes. During this process the cross links, which link the fibers of the cornea, are increased thereby stiffening the whole cornea. A bandage contact lens is then put on the eye and patients are given antibiotics and anti-inflammatory drops and follow up on a regular basis with their physicians for several months.  Many patients notice an improvement in their vision at 3 to 6 months and European studies suggest that only 5-8% of patients need to be retreated.

IT IS VERY IMPORTANT THAT THIS TREATMENT BE DONE ONLY WITH THE EPITHELIUM REMOVED (EPI-“OFF”), this is the only methodology which has been tested in the laboratory and has been shown to be safe for treatment in humans. CLICK HERE TO FIND OUT OTHER REASONS WHY WE DON’T PERFORM OR RECOMMEND THE “EPI-ON” PROCEDUREthat is advocated only by a handful of doctors, the vast minority doing this procedure.

The slide below which is an Electron micrograph of the cornea, which has undergone the procedure, clearly demonstrates that the epithelium acts as a barrier to cross-linking. As you can see from this slide in the areas where the epithelium is missing, the stroma is compacted and cross-linking has occurred, while in the areas where there is epithelium (blue layer) the corneal fibers below are widely spaced and no cross linking or compaction has occurred (see slide below).

Clinical Trial to compare the effectiveness of Collagen Cross linking with or without INTACS to halt the progression of Keratoconus

We are pleased to announce that after studying this technology now for many years we are offering the only Clinical Trial in the United states under an FDA protocol approved by the Western Institutional Review Board (WIRB) which will determine whether it is more efficacious to combine INTACS with collagen cross linking or do cross linking alone to halt the progression of Keratoconus.

Corneal Transplants are the only option for patients who have scarring in the center of the cornea or who are contact lens intolerant because their corneas are too steep. The results of corneal transplants are excellent in keratoconus patients with an over 97% success rate. Patients can have LASIK or PRK on their transplants and become relatively independent of glasses or contact lenses – many of our patients achieve 20/30 or better vision with this combination of procedures.

Recently the Femtosecond Laser was approved for performing Corneal Transplants (also known as I.E.K or Intralase Enabled Keratoplasty).  This is one of the biggest advances in Corneal Surgery in the past 30 years.  The result is a quicker procedure, quicker recovery and less astigmatism with better vision. The Keratoconus Center is one of the few centers in the world that now uses this groundbreaking technology.

Future link to BJO LEK paper.

Sometimes patients who have had a successful transplant with a clear cornea still do not see well and cannot tolerate contact lenses. The reason for this is that they have large amounts of astigmatism following their transplant surgery. This can be corrected with Astigmatic Keratotomy (AK) and followed if necessary by Excimer Laser PRK. In most instances patients then become either contact lens tolerant and can see better with glasses or contact lenses.


In DALK the bottom layer of the cornea is spared this results in less chance of rejection. We perform this technique with all of our I.E.K. surgeries to minimize the chance of rejection. It should be remembered however that in some instances the separation of the bottom layers of the cornea and the upper parts might be uneven which would result in poorer visual outcomes. In these instances we will convert the DALK procedure combined with I.E.K. to an I.E.K. only procedure. We encourage our patients to discuss with us in detail the risks and benefits of each procedure and the combined D.A.L.K. and I.E.K. procedure. Of course we always perform the procedure that is safest with the best visual outcome for all of our patients


Though eye care professionals recommend against Excimer laser PRK in patients with keratoconus because it thins the cornea even further,  we are actively researching this area. Our experience has shown that in patients who are over age 40 whose vision is stable and whose corneas are thick enough they get similar results with the Excimer PRK as they would get with glasses. Patients who elect to undergo this treatment will be done under an experimental protocol and need to understand that they are at increased risk of scarring with the potential for needing a corneal transplant.


Patients who are extremely nearsighted more than -10D might benefit from phakic intraocular lenses. Currently there are two type of these lenses approved by the FDA –the Verisyse and the Visian ICL. These are implantable contact lens has been approved by the FDA for up to -20Diopters. We are one of few centers performing a research study on the use of these intraocular lenses in  keratoconus eyes, This will be an exciting new opportunity for a select number of patients with keratoconus who could potentially improve their vision without the need for laser surgery.


Corneal Transplant Q & A

Ophthalmologists (medical eye doctors) perform over 40,000 corneal transplants each year in the United States. Of all transplant surgery done today, including hearts, lungs and kidneys, corneal transplants are by far the most common and successful.

What Is The Cornea?
The cornea is the clear front of the eye that covers the colored iris and the round pupil. Light is focused while passing through the cornea so we can see. To stay clear the cornea must be healthy.

How Can An Unhealthy Cornea Affect Vision?
If the cornea is damaged it may become swollen or scarred. In either case, its smoothness and clarity may be lost. The scars, swelling or an irregular shape cause the cornea to scatter or distort light, resulting in glare or blurred vision.

A corneal transplant is needed if:

  • Vision cannot be corrected satisfactorily.
  • Painful swelling cannot be relieved by medications or special contact lenses.

What Conditions May Require Corneal Transplants?
Corneal failure after other eye surgery, such as cataract surgery;

  • Keratoconus, a steep curving of the cornea
  • Hereditary corneal failure, such as Fuch's Corneal Dystrophy
  • Scarring after infections, especially after herpes
  • Rejection after first corneal transplant
  • Scarring after injury
  • Complications from LASIK (lamellar transplants)

What Happens If You Decide To Have A Corneal Transplant?
Before Surgery
Before a cornea is released for transplant, the eye bank tests the human donor for the viruses that cause hepatitis and AIDS. The cornea is carefully checked for clarity.
Your ophthalmologist may request that you have a physical examination and other special tests. If you usually take medications, ask your ophthalmologist if you should continue them.
The Day of Surgery
Surgery is often done on an outpatient basis. You may be asked to skip breakfast, depending on the time of your surgery. Once you arrive for surgery, you will be given eye drops and sometimes medications to help you relax.
The operation is painless. Anesthesia is either local or general, depending on your age, medical condition and eye disease. You will not see the surgery while it is happening, and will not have to worry about keeping your eye open or closed.
The Operation
The eyelids are gently opened. Looking through a surgical microscope, the ophthalmologist measures the eye for the size for the corneal transplant.
The diseased or injured cornea is carefully removed from the eye. Any necessary additional work within the eye, such as removal of a cataract, is completed. Then the clear donor cornea is sewn into place.
When the operation is over, the ophthalmologist will usually place a shield over your eye.
After Surgery
If you are an outpatient, you may go home after a short stay in the recovery area. You should plan to have someone else drive you home. An examination at the doctor's office will be scheduled for the following day.
You will need to:

  • Use the eye drops as prescribed
  • Be careful not to rub or press on your eye
  • Use over-the-counter pain medicine, if necessary
  • Continue normal daily activities except exercise
  • Ask your doctor when you can begin driving
  • Wear eyeglasses or an eye shield as advised by your doctor
  • Your ophthalmologist will decide when to remove the stitches, depending upon the health of the eye and rate of healing.

* Usually, it will be several months, at least, before stitches are removed.

What Can I Expect After Corneal Transplant Surgery?
Cornea Transplants are done on an outpatient basis. The procedure itself takes 45 minutes to 75 minutes depending on the complexity of the situation. You should expect to spend the whole morning at the outpatient surgery center however.
When you leave the hospital you will wear a patch and a shield. This will be removed the next day at your follow up visit at the doctor's office. After that you will be wearing dark glasses during the day and a protective shield at night only. Your vision will be blurry for approximately 3 - 6 months.
At 3 months you will start having your sutures removed and they should all be removed by the end of 6 months a little longer if you are older. At the end of 6 months you will be fitted with glasses or contact lenses. During the whole 6-month period you will take anti -rejection drops and antibiotic drops approximately 4 times a day.
For the first 6 weeks heavy exercise and lifting of heavy objects will be prohibited, but otherwise you can live a normal life. Most people return to work 3 to 7 days after their surgery depending on the type of work they do.
Corneal transplants are rejected 5% to 30% of the time. The rejected cornea clouds and vision deteriorates.

Can I Get Rid Of Contacts Or Glasses After Transplant Surgery?
Yes it is possible to be free of contact lenses or glasses after transplant surgery. This will however require additional procedures such as astigmatic keratotomy or LASIK. The fees for these procedures are not included in the cost of the original procedure and may not be covered by traditional insurance, though under certain circumstances they may be covered.
After all the sutures are removed most patients are left with a certain amount of nearsightedness and astigmatism. This can be corrected either with Rigid contact lenses or glasses.
If the astigmatism is large this can be corrected with astigmatic keratotomy to bring the patient to less than 4D of astigmatism. Patients with less than 4D of astigmatism and less than 8D of myopia can then have their vision corrected with LASIK.
We have many patients who have successfully undergone these procedures and some of them would be happy to talk to you about their experiences.

Who Is Best Qualified To Do A Cornea Transplant?
The person most qualified to do a cornea transplant is an ophthalmologist fellowship trained in cornea transplant surgery. Transplant surgeons who have an academic interest in the advancement of knowledge on cornea transplantation are also members of the Castroviejo Cornea Society. For further information on Ronald N. Gaster M.D, fellowship trained cornea transplant surgeon and member of the cornea society. Click here to learn more about Dr. Gaster

What Complications Can Occur?
Corneal transplants are rejected 5% to 30% of the time. The rejected cornea clouds and vision deteriorates.
Most rejections, if treated promptly, can be stopped with minimal injury. Warning signs of rejection are:

  • Persistent discomfort
  • Light sensitivity
  • Redness
  • Change in vision

Any of these symptoms should be reported to your ophthalmologist promptly.
Other possible complications include:

  • Infection
  • Bleeding
  • Swelling or detachment of the retina
  • Glaucoma

All of these complications can be treated.
A corneal transplant can be repeated, usually with good results, but the overall rejection rates for repeated transplants are higher than for the first time around.
Irregular curvature of the transplanted cornea (astigmatism) may slow the return of vision but can also be treated. Vision may continue to improve up to a year after surgery.
Even if the surgery is successful, other eye conditions, such as macular degeneration (aging of the retina), glaucoma or diabetic damage may limit vision after surgery. Even with such problems, corneal transplantation may still be worthwhile.

A successful corneal transplant requires care and attention on the part of both patient and physician. However, no other surgery has so much to offer when the cornea is deeply scarred or swollen. The vast majority of people who undergo corneal transplants are happy with their improved vision.

Of course, corneal transplant surgery would not be possible without the hundreds of thousands of generous donors and their families who have donated corneal tissue so that others may see.

Patient Testimonials

“Dr. Gaster saved my life! I had struggled with keratoconus which meant my vision was blurry because of a rare eye condition. He reassured me that everything was going to be okay with the procedure he went to Germany to learn and from there was able to help individuals with the same condition I had. I've had both eyes done and visit him often.

He's kind, gentle, funny, patient, ca and full of life. I would recommend him to ANYONE that is willing to fix their vision with this process. It is a commitment that is more than worth it. If you have any questions please contact his office.

The staff is AMAZING they are happy to answer all the questions you have and will work with you on correcting this speed bump in your way. Thank you Dr Gaster!!!”

Jeffrey J. - Torrance, CA

“Dr. Gaster is a knowledgeable ophthalmologist and a wonderful, kind human being. I was diagnosed with Keratoconus at a young age and have been under his care for about 5 years. I am fortunate to have found him. In the last 5 years, Dr. Gaster has allowed me to reach the best vision I can. After a corneal crosslinking procedure, a corneal transplant, and PRK, I see respectively 20/25 in both eyes (unaided). This is a significant improvement as I was 20/60 in the right eye and 20/4 fingers in the left.

Dr. Gaster is extremely straightforward. He will not recommend a procedure he does not think is necessary, will thoroughly review details (along with complications), and answer any questions. His honesty is refreshing because other doctors, in my experience, will allude to being able to somehow cure or “conquer” your Keratoconus – which is not the case at all. A frank conversation with a medical professional is imperative for anyone who has a progressive, chronic disease (such as Keratoconus).

There have been several times when Dr. Gaster has kept me “grounded” by reminding me of

  • Where my vision was when I first started seeing him and
  • How grateful I should be for the great vision I have now.

There are times when I become impatient or discontent as I still want to have that “perfect, 20-20” vision. Undoubtedly, his reminders are much needed. Furthermore, Dr. Gaster has a strong work ethic that truly benefits his patients. He’s answered emails and taken phone calls during after-hours.

In regards to the procedures, the surgeries have been life changing. For the first time in over a decade, I have functioning vision in my left eye. No words could ever describe how thankful my family and I are to him. We value and respect him.

I have such wonderful memories and positive things to speak of Dr. Gaster because he has always been supportive and professional. There have been times where I have lost my composure, either before surgery or during a post-op appointment, and he has always been able to handle the situation with great care (my apologies for the anxiety and the few tears I’ve shed!).

So if you need an ophthalmologist, pay him a visit! Be ready for straightforward discussions.
Much luck to all of you!
Esther V. - West Hills, CA

"I am an ophthalmologist with keratoconus and had the INTACS with Intralase procedure performed by Dr. Rabinowitz in October 2006. Speaking from the perspective of both a keratoconus patient and an eye doctor, I must say that I am truly impressed with the procedure. It was amazing- my astigmatism was reduced by 50% and my vision imporved by 3 lines on the vision test chart.

This procedure allowed me to improve the quality of my work and my personal life. I always thought that I would need a cornea transplant some day, but this procedure has allowed me to defer the need for a transplant at this time. The procedure was fast, easy, and painless. I would do it again in a heartbeat without hesitation or reservation.

As each patient is different, expectations are key to the success of this procedure. The purpose of the procedure is not to make your vision perfect, it is to improve the astigmatism and thus lessen distortion. You still will have keratoconus after INTACS, however you will hopefuklly have better vision with glasses, contact lenses, or both.

I feel this procedure has given me a new lease on my future.
Thank you Dr. Rabinowitz and staff for your expertise and excellent work!
