Predictors for likelihood of corneal transplantation in keratoconus.
A group of 70 patients who had attended the Keratoconus Clinic at Moorfields Eye Hospital over a 10-year period were analysed retrospectively. At the end of this period 23 eyes had undergone corneal transplantation. This gave an overall probability of 16%, various information obtained at the initial visit was then analysed for a possible relationship with the probability of needing a transplant within ten years. The only significant relationship found was the initial corneal radius as determined by the back optic radius of the first contact lens. A graph was constructed plotting probability of corneal transplant against each radius at the first visit, which could assist clinicians in advising patients.
