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