Corneal Cross Linking has emerged as a very potent tool for treating Keratoconus patients.
In some patients, LASIK or any other form of laser vision correction is not possible. In such patients, their corneas are structurally weak, and they bulge out in a certain section, in the form of a cone. Initially, the patients experience blurred vision, and changing eye glass numbers. Eventually, they start loosing vision, and they can also experience a lot of pain. Such patients are said to have keratoconus.
Keratoconus is a progressive disease of the cornea, and the usual onset is just around reaching adulthood, till around 25. In some patients, it goes on progressing, and in others, it stops progressing after a while. It does not reverse what has already occured.
Till about 7-8 years ago, the only option for patients with keratoconus was to wear a hard contact lens (to smoothen the cone), and to wait for stabilization of the disease as part of its natural course. In those patients where it would not stabilize, it would mean a corneal transplant as a final outcome.
Since the last few years, corneal cross linking has emerged as a very good alternative to strengthen the cornea. The cornea is saturated with riboflavin eye drops, and then exposed to UV radiation. The combination of Riboflavin and UV light exposure causes cross linking of the corneal fibres, which increases the structural strength of the cornea.
The aim of Corneal Cross Linking is to strengthen the cornea,and to stabilize the progression of Keratoconus. In some cases, it also partially reverses the disease. At New Vision, we also offer an option of a topolink PRK in combination with Corneal Cross Linking (or C3R) to offer a better visual outcome for the patient.
Some patients who undergo Laser Vision Correction can also get a related condition called Keratactesia. This can also be resolved using Corneal Cross Linking or C3R.
