ABSTRACT
PURPOSE: To analyze the fitting characteristics of contact lens, according to the clinical findings keratoconus of in Koreans. METHODS: The topographic indices were evaluated in 106 keratoconic eyes of the 53 patients, who had been followed up for at least 1 month, and their fitting pattern parameters retrospectively analyzed. The visual acuity, epithelial erosion, glare, daily lens wearing time, pain and the changes in the topographic indices were evaluated after fitting. RESULTS: The number of eyes fitted with spherical RGP, aspherical RGP and multicurve RGP were 19, 6 and 81 eyes with mean base curve radius (BCR) of 7.67, 7.17, and 6.76 mm, respectively. The Sim K and temporal K 3 mm from the center were significantly correlated with the BCR. 77 eyes achieved visual acuity of 20/30 or better, and the mean daily wearing time was 11.6 hours. Glare and pain were reported in 4 and 7 eyes, respectively, and progression of epithelial erosion was found in 8 eyes. The mean anterior elevation and sim Kmax in lens intolerable eyes were 0.0745 mm and 59.35 D, which were significantly higher than 0.0584 mm and 54.22 D in lens tolerable eyes. No progressive keratoconic changes were observed in the topographic indices for the eyes fitted with the multicurve lenses. CONCLUSIONS: Appropriate fitting guide-lines could be established by analyzing the fitting and clinical characteristics in keratoconus.
