Primary posterior capsular opacification (PPCO) refers to the posterior capsule opacification which cannot be removed by polishing or vacuuming during cataract surgery. The surgeon may have to decide on primary posterior capsulorhexis or early neodymium-doped yttrium aluminum garnet (Nd:YAG) laser capsulotomy in these cases. The aim of this study is to compare the visual acuity, visual quality, operative complications and the satisfaction of patients between primary posterior capsulorhexis group and laser capsulotomy group of cataract patients combined with primary posterior capsular opacification (PPCO).
This is a two-arm, parallel group, open-label, randomized controlled trial to compare the visual acuity, visual quality, operative complications and the satisfaction of patients between primary posterior capsulorhexis group and laser capsulotomy group of cataract patients combined with primary posterior capsular opacification (PPCO).
