Evaluation the effect of posterior sub-capsular cataract on the refractive state of eye

Background: Cataract refractive errors are caused by cataracts. It can go up to several dioptres (D). Correction of expected during cataract surgery altering the axial length measurement. Determine effect posterior sub-capsular cataracts on eye's status. Methods: 112 patients with participated in study. The most common error found PSC was astigmatism, followed myopia. study conducted at Angel Eye Institute Ophthalmology; Kanpur U.P. status eyes determined using retinoscopy and subjective refraction. Biometry is done A-scan keratometer. Results: A total were included this Of these, 27 (26.5%) males 75 (73.5%) females. Patient’s age about 60 years. results showed that mainly myopic astigmatism (97. 1%) spherical myopia (2.9%), 0.16SD. mean value (1.7D, 15.7%), 0.93 SD (0.1 D, 2.9%), 0.67 SD. Mean uncorrected visual acuity 1 log MAR 1.6 corrected 0.3 1.2 Conclusions: significant These findings may help clarify type prediction ocular vision outcome.
