Summary

The purpose of this study is to compare the accuracy of capsulotomy assisted by intraocular caliper and Verion navigation system in phacoemulsification surgery and postoperative visual quality for age-related cataract patients with corneal limbus opacity.

Conditions

  • Cataract Extraction

Interventions

PROCEDURE

Intraocular caliper-assisted capsulotomy

Intraocular caliper is a modified intraocular caliper with standard calibration on the rinse needle.

PROCEDURE

Verion navigation system-assisted capsulotomy

Verion Image Guided System (Alcon Laboratories, Inc.) is a digital image guidance system consisting of a diagnostic reference unit and a surgery pilot for intraoperative surgical assistance. The device can be used to align toric intraocular lens during surgery as well as support manual creation of a capsulorhexis with a predefined target diameter.
