Overview

Evaluation of capsular bag shape changes after plate-haptic intraocular lens implantation by SS-OCT.

Eighty patients (80 eyes) with simple age-related cataracts were treated from December 2019 to December 2020 in the Wenzhou Medical University. Investigators specifically included patients who were bodily healthy and underwent a successful implantation of an IOL. Inclusion criteria for this study were patients who were older than 40 years old, had an axial length of 22-26mm, and could complete 4 follow-up visits.

Outcomes

Primary Outcomes

Capsular bend index (CBI)

capsule bend formation has 5 continuous stages from 0 to 4，The stage score varies over different positions of the same capsule bag, because the capsule bend formation is inconsistent along the entire optic edge. CBI is the mean of the different stage scores in different positions and represents the general capsule bend state of the whole capsule bag.
