Keratoconus is a bilateral, progressive disorder of unknown cause, affecting young people between 15 to 25 years of age, in which there is non-inflammatory thinning and forward bulging of the front surface of the eye ‘the cornea’.
This may be diagnosed clinically, but usually needs specialised equipment like Pentacam (corneal topography mapping) for confirmation. Keratoconus is a progressive disease and C3R is the latest treatment available for Keratoconus, which helps in retaining the vision. Though C3R is not a cure for Keratoconus, it has proven really successful in arresting the progression of the disease. It will retain your vision and help in avoiding corneal transplantation.
Medilaser offers C3R that can arrest progression of Keratoconus and can also partially reverse the corneal steepening that has already taken place.
What Does C3R Involve?
This procedure takes around 30 minutes wherein the cornea is first anaesthetised using drops. A clip is placed in the eye to keep the lid open. The outer surface is disrupted using a special instrument and then riboflavin (vitamin B2) drops are placed in the eye every 5 minutes. The drops are yellow and are absorbed by the cornea and the front of the eye. Our surgeons will regularly be checking to ensure it has been absorbed.
After this a calibrated ultra violet device is focused on the eye and switched on for 6 cycles, 5 minutes each. It is important not to move during this procedure, the doctor will make sure the device is in the correct position. The yellow dye riboflavin absorbs the ultraviolet “A”/UVA light. Once the procedure is completed, a soft bandage is placed with antibiotics.
