Endothelial Cell Loss After Cataract Surgery

NCT00932191 · Status: TERMINATED · Phase: PHASE2/PHASE3 · Type: INTERVENTIONAL · Enrollment: 39

No results posted yet for this study

Summary

The purpose of this study is to compare two cataract surgical technique variations for removing the nucleus of the lens (central part of the lens) in terms of damage to the inner layer of the cornea which is called the endothelium. One variation uses more ultrasound energy and the other more mechanical force to break up the nucleus.

Conditions

  • Cataracts

Interventions

PROCEDURE

Standard phacoemulsification

Cataract nucleus removal using standard amounts of ultrasound energy

PROCEDURE

Reduced ultrasound phacoemulsification

Cataract nucleus removal using less ultrasound energy and more mechanical energy.
