Abstract

We evaluated the morphological characteristics and intraoperative dynamics of posterior polar cataract (PPC) using intraoperative OCT (iOCT). Three morphological variants of PPC were observed on iOCT- Type I with intact PC and clearance between PC and opacity, type II with intact PC in periphery of opacity, shadowing and inability to detect PC in centre and type III with dense opacity, extensive shadowing and inability to delineate PC. In addition to hydrodelineation, hydrodissection was performed in all cases of type I PPC with no case developing PC dehiscence. In type II and III PPC, only hydrodelineation was performed; three cases developed PC dehiscence (type II-1 eye, type III-2 eyes). iOCT-guided surgery helps elucidate intraoperative dynamics in PPC and assess real-time PC integrity. It characterizes high-risk morphological features, enables safe hydrodissection in a subset of PPC; however, iOCT does not decrease the incidence of PC dehiscence.
