Summary

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

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).

Conditions

• Cataract

Interventions

Type	Name	Description
PROCEDURE	Subluxation	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.
PROCEDURE	Divide and conquer	Cataract nucleus is fragmented into 4 pieces then aspirated by ultrasonic vibration
