Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To compare the impact of two phacoemulsification techniques (subluxation versus divide-and-conquer) on postoperative corneal edema at postoperative hour 1 and day 4.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Phacoemulsification is the procedure of choice for most surgeons performing cataract surgery. Alternative techniques have been in development over the last twenty years, with the hope of optimizing operating times, total ultrasound energy used, patient safety, patient satisfaction and visual recovery associated with cataract surgery.

Divide-and conquer is the parent nucleofracture technique.The subluxation technique is a newer technique that is less frequently used because of an increased risk of corneal endothelium damage.

The aim of this comparative study was to evaluate corneal edema immediately after surgery performed with the subluxation technique versus divide-and-conquer. Corneal edema was determined by measuring central corneal thickness (CCT).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Subluxation

Nucleus is hydrodissected until it lilts above the capsular bag, rotated to face the incision then tumbled and emulsification continues from the opposite equator outside in until complete

Subluxation

Intervention Type PROCEDURE

One pole of The nucleus is hydrodissected until it lilts above the capsular bag. The tilted nucleus is rotated to face the incision and remaining half nucleus is then tumbled and emulsification continues from the opposite equator outside in until complete.

Divide and Conquer

Cataract nucleus is fragmented into 4 pieces then aspirated by ultrasonic vibration
