Abstract Today, cataract surgery has become a technically advanced and very standardized procedure. Posterior capsule opacification is the most common post-operative problem, which results in a decrease of the visual acuity. In our study, we have evaluated the effect of anterior capsule polishing on the development of PCO. In this study, a comparison was made between two groups. In group one polishing of the anterior capsule using Koch aspiration cannula (Geuder) was done. In group two, phacoemulsification was completed without polishing of the anterior capsule. The two groups were compared in terms of V.A, IOP and severity of PCO which was assessed both clinically and objectively using Open Access Systematic Capsule Assessment (OSCA) program. This study proved that polishing of the anterior capsule is effective in decreasing the severity rather than prevention of PCO. This was evidenced by the fact that average (OSCA) score in group 1 following first month is 1.0012 versus 1.6949 in group 2 (P value = 0.0006). Following 6 months values were 1.29781 & 1.8169 respectively (P value = 0.1574), denoting statistically significant difference between OSCA values after first month that turned to be statistically nonsignificant after six months period. In this study, change of BCVA over six months correlated with changes in (OSCA) score.Following first month, average BCVA in group 1 was 0.71±0.26, and in group 2 was 0.54±0.25.As for BCVA after six months, group 1 had an average of 0.59±0.26 versus 0.4±0.18 in group2. This study also showed that polishing the anterior capsule affects the morphology of PCO. Polishing decreases the incidence of development of Elschnig pearls. OSCA program has proved to be user friendly, reproducible and cheap. It’s important to investigate the role of anterior capsule polishing in high risk groups e.g.: uveitic patients, patients with PXF or in retinitis pigmentosa. Also, further studies with longer follow up periods are recommended. |
