Influence Of Anterior Capsule Polishing On Capsular Bag And Intraocular Lens After Phacoemulsification

To evaluate if anterior capsule polishing could minimize the chance of posterior capsular opacification which needs Nd-Yag capsulotomy and anterior capsular opacification/anterior capsular contraction syndrome which influences the position of the intra ocular lens in the capsular bag.

In this prospective study 120 eyes of 60 consecutive patients with bilateral age related cataract who underwent phacoemulsification were evaluated. Each patient's eyes were randomly assigned to two groups. One eye received 360 degree anterior capsule polishing (Group-A: Cases) and the fellow eye without anterior capsule polishing (Group-B: Controls). In this study, capsulorrhexis size is uniform as we used corneal capsulorrhexis marker (5mm at the anterior capsule). All eyes were implanted with similar type of intra ocular lens. Eyes were evaluated at 1^st week, 1^st,3^rd,6^th month and 1^st year.

All eyes were evaluated with slit lamp biomicroscope, A-SCAN ultrasonography and anterior segment OCT. Significant reduction in the formation of posterior capsular opacification, anterior capsular opacification and anterior capsular contraction syndrome were noted in Group-A (eyes which received 360 degree of anterior capsule polishing).

Anterior capsule polishing had positive influence by reducing the formation of PCO which minimized the need for Yag capsulotomy(which has its own complications such as Cystoid macular oedema,post Yag uveitis,raise in IOP and retinal detachment), reducing post operative refractive error(due to ACCS).
