What Is Keratoconus?
Keratoconus is a progressive disease that causes gradual thinning of the cornea (the clear window covering the eye). This degenerative condition leads to structural changes and weakening of the corneal tissue over time. Eventually, the normally round cornea deforms into a cone shape, which fails to properly refract light onto the retina. This causes impaired visual acuity and may continue to worsen over time as vision begins to appear distorted or blurry. In patients with keratoconus, the cornea has the potential to eventually undergo irreversible deterioration.
Board-certified ophthalmologist Dr. Ralph Chu is highly experienced in diagnosing and treating keratoconus. He offers some of the most advanced procedures available in the ophthalmic industry to prevent future vision loss and help patients gain clearer eyesight.

"Bare with my lengthy review but if you’re like me, I wanted to know what others true thoughts were and I scoured as many reviews as possible to make sure I was making the best decision for me and my eyes. I am SO, SO thankful for Dr. Chu and Dr. Heckman’s expertise and honesty. I decided it was time to get Lasik and went in for my consultation. From check-in to my latest follow up, everyone at the Chu Vision Institute was friendly, warm, and helpful. Due to some past corneal scarring, Dr. Chu recommended that I get Lasik on one eye and PRK (ASA) on the other. I was extremely nervous about PRK because of the slightly longer recovery time and I really just wanted to wake up and have 20/20 vision like my friends who have had Lasik. The day of my procedure, they made sure I had all my questions and concerns answered before they let me in to have my surgery. That was extremely comforting to me and Dr. Heckman explained why PRK was recommended over Lasik. Simply put, I wouldn’t have had a good outcome if Dr. Chu had performed Lasik on both eyes. Both procedures went well and Dr. Chu confirmed his right decision during the procedure which took all of maybe 10 minutes for both eyes. As instructed, I went home and rested and could literally see 20/20 the next day with my Lasik eye. The PRK eye takes a little longer to heal but can already see better! (I was worried my blurry eye would affect my vision, but it did not). Recovery has been great and will continue to get better in the next few weeks. Now my husband wants to get his eyes done. Chu Vision Institute has exceeded my expectations and I am very happy with my results!"- E.M. / Google / Oct 20, 2020

"I’ve been going to Chu vision for about three years now and and I’ve had excellent service each and every time. They follow me yearly for my dry eye condition. They are extremely thorough and take the time to answer all my questions. Highly recommend them."- C.S. / Google / Jul 31, 2020
"Exceptional. I felt like family as soon as I walked through the front door. Staff was extremely knowledgeable and friendly and my LASIK procedure went flawlessly. Like most folks, I did extensive research for months before my consult (word of mouth and online) I highly recommend Chu Vision for your procedure."- C.M. / Google / Mar 19, 2020
"I want to thank everyone at Chu Vision for the remarkable care we received recently. The clinic has an immaculate protocol to prevent Covid exposure for all of its patients. One might think that all the masks would prevent a warm, caring environment but not at Chu Vision! To a person, everyone was warm and welcoming. Dr. Chu was terrific and extremely thorough. The clinic was able to assess my husband’s acute vision change using a remarkable variety of tests and tools. What would have taken weeks at another clinic took only hours at Chu Vision. We won’t ever go anywhere else. Thank you so very much!"- K.D. / Yelp / Jul 13, 2020
Symptoms of KERATOCONUS
Keratoconus tends to develop in the teenage years or early 20s. Symptoms may progress slowly over time, which can make this corneal condition difficult to diagnose at first. In some cases, the onset can occur later in life. Keratoconus tends to go undiagnosed until obvious symptoms start to appear. The most common signs are:
- Sensitivity to light
- Distorted or blurry vision
- Progressively worsening far-away vision
- Frequent eye prescription changes
Since the symptoms of keratoconus can present similarly to those of other ocular conditions, it's essential to have your eyes examined by an ophthalmology specialist.
Causes OF KERATOCONUS
Keratoconus is typically an inherited condition. However, it can also develop as a result of environmental factors, including excessive UV light exposure, an enzyme imbalance within the cornea, chronic eye rubbing, improperly fitted contact lenses, or corneal thinning following eye surgery. Dr. Chu recommends that everyone have regular comprehensive eye exams at least every other year to check for many eye diseases and complications, including keratoconus.
KERATOCONUS Treatment Options
Dr. Chu can provide a number of innovative treatment options for keratoconus, which are customizable based on the phase and severity of your disease. If you are in the early stages of keratoconus, we may give you a prescription for eyeglasses or contact lenses to manage your condition. In the later phases, a more advanced treatment may be needed. We offer corneal cross-linking, phototherapeutic keratectomy (PTK), and both partial- and full-thickness corneal transplants. When you visit our office for your initial consult, we will conduct a comprehensive eye exam and review your health history to determine the best treatment to improve your vision.
Keratoconus is Treatable
Although keratoconus can result in partial or total vision loss, it is possible to prevent or slow these symptoms by having the condition diagnosed and treated. Because it is a degenerative condition, it is important to have an eye exam as soon as you notice signs. Dr. Chu and the skilled team at Chu Vision Institute have years of experience helping keratoconus patients protect their sight and eye health.
