Keratoconus London

Treatment options

Contact lenses and glasses

For milder forms of the condition, glasses may be sufficient. However, in more advanced forms, a specialist contact lens is required to account for the irregular cornea. At Vision Correction London, we work closely with specialist keratoconus contact lens fitters and can help arrange an appointment to have you fitted with an appropriate lens.

In most cases of keratoconus, contact lenses are sufficient to improve vision and if the condition is non-progressive, no further treatment is required.

Corneal collagen crosslinking

Corneal collagen crosslinking

Corneal Collagen Crosslinking with Riboflavin (also known as C3R) is a procedure that has been shown to strengthen the weak corneal structure. The cornea is made up of many layers of collagen arranged in a very regular pattern with cross links for strength. C3R works by increasing collagen cross-linking thereby strengthening the cornea. Studies have shown the cornea is strengthened by over 300% following this procedure.

During the procedure, riboflavin eye drops are applied to the cornea. The surgeon then uses UV light to activate the riboflavin, inducing the strengthening cross-links in the cornea. This is a short procedure performed as a day-case and is offered if the keratoconus is progressive. The aim of treatment is to prevent any further deterioration.

Laser corneal re-modelling combined with crosslinking

During this procedure, patients have a defined amount of laser treatment to reshape their cornea and this is then locked in with the crosslinking procedure.

This improves the shape of the cornea and halts progression of the disease at the same time and is an option for select patients who meet the rigid criteria.

It is a relatively new treatment option and the results can be impressive. We have already seen a large percentage of patients able to reduce their dependency on glasses and contact lenses. The amount of reshaping that can be achieved will depend on the initial corneal thickness and degree of irregularity all of which are determined at your consultation.

Intra-corneal rings which improve the shape of the cornea

These are clear, thin prescription inserts placed in the outer periphery or edge of the cornea during a short procedure performed as a day case. The rings act as scaffolding to support the cornea. They flatten the peak of the cone returning the cornea to a more natural shape. The criteria for intra-corneal rings are also fairly rigid and the results less predictable compared to laser remodelling.

Implantable Collamer Lenses

Implantable collamer lenses (ICL) consist of a very thin bio-compatible material which is inserted in front of the natural lens. These are useful in select patients where there is good vision with glasses but the prescription is high or difficult to tolerate. Read more about ICL surgery.

Corneal Transplantation

Corneal transplantation refers to replacement of all or part of the cornea with a donor cornea. Modern techniques now allow us to transplant only the affected component of the cornea rather than the entire cornea.

In keratoconus, we try and preserve the normal back layer of the cornea wherever possible by replacing only the damaged front layers.

In this way, success rates are improved significantly and the risks of surgery are reduced considerably.

A full assessment with one of our surgeons will establish which procedure is most suitable for you and likely to result in the best outcome.

“I have been a patient of Ali Mearza for over 8 years now and I don’t know what I would have done without such an amazing surgeon who is so passionate about what he does. My life was upside down due to severe keratoconus in both eyes, after a few different eye surgeries Mr Mearza had to graft both eyes. I can’t tell you how much my quality of life has changed thanks to his amazing work. I can now see again even without glasses or lenses. I have full confidence in Mr Mearza’s work and would recommend him to anyone that needs to have eye surgery.”
