PURPOSE: To study the clinical performance of rigid gas permeable contact lenses (RGPCL) in @entity1 with @entity528 ( @entity528 ). METHODS: This retrospective study consisted of 15 @entity1 with clinical @entity528 , confirmed by videokeratography ( @entity938 , Computed Anatomy, Inc., New York, NY). Information collected from the medical records included @entity1 demographic data, uncorrected visual acuity, refraction, best-corrected spectacle visual acuity, and topographic details, including kerotometry. Twenty-seven of 30 eyes were subjected to several contact lens trials using @entity4625 ( @entity4625 ) contact lenses, using a systematic and consistent approach. After successful contact lens trials, data regarding number of trials, trial time, final contact lens choice parameters, and best-corrected contact lens visual acuity were noted for each @entity1 . During follow-up, visual acuity with RGPCLs, lens fit, and average wearing time were noted. RESULTS: Fifteen @entity1 (30 eyes) with typically inferiorly located @entity528 were included in this study. There were 12 @entity1 and 3 @entity1 , with a mean age of 39.73 years. Twenty-seven eyes of 15 @entity1 were identified as subjects for multiple contact lens trials, and 24 (88.8%) eyes were successfully fitted with RGPCLs. Best-corrected visual acuity of 6/12 or better with spectacles was achieved in 14 (46.66%) eyes. The average @entity940 was -8.56D, and a majority of the @entity1 with @entity528 who were in the contact lens trial had an against-the-rule @entity940 (63.3%). The mean trial time for attempted eyes (i.e., @entity1 with @entity528 who successfully underwent the contact lens trials) was 77.7 minutes, and the number of trials required to finalize the choice of contact lenses ranged between 2 and 7. The median base curve for RGP lenses was 7.57, and median diameter was 10.00 mm. Best-corrected visual acuity of 6/12 or better with the final contact lens was achieved in 95.4% of the subjects. After an average follow-up of 22.91 months, one @entity1 was lost to follow-up, and 2 eyes required discontinuation of the contact lenses. The average wearing time among the contact lens wearers at their last follow-up visits was 9.58 hours. Final visual acuity of 6/12 or better was observed in 77.3% of eyes at the end of 22.91 months. CONCLUSION: Large-diameter RGPCLs are better tolerated and lead to significant improvement in visual acuity in inferior @entity528 .
