Why carry out this study?

Posterior capsular opacification (PCO) is the most frequent long-term vision affected complication of cataract surgery. However, whether high myopia is a risk factor for PCO formation remains controversial.

In this study, we evaluated the long-term outcomes of PCO in highly myopic eyes and its influencing factors.

What was learned from the study?

PCO was more severe and frequent in highly myopic eyes compared with controls.

Longer axial length and follow-up duration were associated with higher risk of PCO in highly myopic eyes.

In highly myopic patients with higher risk of PCO, posterior capsular polishing should be properly performed to prevent PCO.
