Key Points

To identify factors associated with different types of cataracts following pars plana vitrectomy.
Analyzed cataract types post-surgery
Examined links to underlying diseases and patient age
Evaluated effects of silicone oil tamponade and surgery duration
Nuclear sclerosis was identified as the most common cataract type post-PPV.
Specific factors led to posterior subcapsular cataract progression.
Longer surgery duration, younger age, and silicone oil tamponade correlated with cataract formation.

Abstract

Nuclear sclerosis was the most common type of cataract after PPV. Posterior subcapsular cataract progression was associated with specific factors, including PDR, PCV, silicone oil tamponade, longer operative duration and younger age. These findings could be used to prognosticate cataract following PPV.
