Not Applicable
Conditions

Procedure: PanOptix IOL implantation
Registration Number

Brief Summary

To evaluate IOL position, clinical outcome of PanOptix in high myopic cataract patients

Detailed Description

A prospective, single center study to evaluate IOL position, clinical outcome of PanOptix in high myopic cataract patients.

The objective of this study to investigate the refractive and visual performance of PanOptix and explore their correlation with ELP change, capsular bending formation, IOL tilt/decentration in high myopic cataract patients.

PanOptix IOL provides good refractive outcomes and visual quality because of few ELP change, fast capsular bending formation and few tilt and decentration in high myopic cataract patients.
