Keratoconus is a condition in which the cornea (the clear front surface of the eye) develops an irregular conical shape, causing your vision to blur. Several treatments are available, including glasses, contacts, corneal implants and corneal transplants, depending on the stage and severity of your condition.
Eye Institute offers an innovative and highly effective treatment called corneal collagen cross-linking. The purpose of this procedure is to halt the progression of keratoconus. In some people, the treatment may even improve vision.
The treatment uses a combination of riboflavin (vitamin B2) and UV light to form bonds between the collagen fibrils in your cornea. These bonds strengthen the cornea, halting the progression of keratoconus. It can also help flatten the central cornea in about 50% of patients, who often experience better vision as a result.
The procedure is relatively simple and highly effective. It’s also very safe, and complications are extremely unlikely.
What to expect from the corneal collagen cross-linking procedure:
Before the procedure, we’ll give you local anaesthetic drops so that you won’t feel any pain.
Your surgeon will carefully and painlessly remove the surface of your cornea.
Riboflavin drops will be applied to your eye for 20 minutes.
We will then apply a measured dosage of UV light to your cornea for a further 10 minutes. Together with the riboflavin, the UV light encourages bonds between collagen fibrils to form, strengthening your cornea.
After the treatment, a bandage contact lens will be placed on your eye to help heal and make your eye more comfortable. You’ll need to keep this in place for a few days. We’ll also give you eye drops to use. Any discomfort during healing is usually mild, and should only last the first few days.
Corneal collagen cross-linking is an exciting new development in keratoconus treatment that could save your sight, especially if you receive treatment early on. Even those who we treat later find that it halts the condition’s progression, preventing the need for a corneal transplant.

Keratoconus can be diagnosed through a routine eye exam. Your ophthalmologist will examine your cornea, and may measure its curvature. This helps show if there is a change in its shape. Your ophthalmologist may also map your cornea’s surface using a special computer. This detailed image shows the condition of the cornea’s surface. Click here to read more.
In a first-ever collaboration, 4 supranational cornea societies joined forces in a complex, multistep process to develop the Global Consensus on Keratoconus and Ectatic Diseases.1 A total of 45 keratoconus (KC) specialists—9 section coordinators and 36 expert panelists nominated by the societies—focused on 3 topics: Definition/ Diagnosis, Nonsurgical Management, and Surgical Management. In the article below, 3 of the section coordinators talk about the consensus process, key findings, and next steps for clinicians and researchers involved with ectatic disorders.

In the mildest form of keratoconus, eyeglasses or soft contact lenses may help. But as the disease progresses and the cornea thins and becomes increasingly more irregular in shape, glasses and regular soft contact lens designs no longer provide adequate vision correction.
