PurposeThe aim of the study reported here was to compare the improvement of visual acuity (VA) of diabetic and nondiabetic patients after neodymium-doped yttrium-aluminum-garnet (Nd:YAG) laser capsulotomy.MethodsIn this prospective cohort study, 50 age- and sex-matched patients, comprising 25 nondiabetics and 25 diabetics (referred to as Group A and B, respectively), with posterior chamber poly(methyl methacrylate) non-foldable intraocular lens implants attending our clinic at Karachi for capsulotomy had pre- and postoperative measures of VA, posterior pole visibility, and grading of posterior capsular opacity as seen on slit-lamp examination. VA was recorded before and after performing standard capsulotomy.ResultsThe postoperative (mean) VA in nondiabetics was 0.25, 0.23, and 0.21 logMAR as compared with 0.25, 0.25, and 0.24 logMAR in diabetics at 1 week, 1 month, and 6 months, respectively. P-values of 0.47, 0.47, and 0.24, respectively, were determined, which were not significant. Preoperative VA improvement was recorded in 92% of diabetics in Group B and 96% of nondiabetics in Group A. Two (8%) diabetic patients developed glaucoma and did not participate in the study further.ConclusionRemarkable improvement in VA was achieved in both Group A and B, but the Group A nondiabetics showed more improvement in best-corrected VA after Nd:YAG laser capsulotomy.
