Purpose

This prospective randomized controlled trial aims to evaluate the effectiveness and safety of a 180° nuclear flip technique in phacoemulsification cataract surgery, comparing it with the traditional endocapsular approach for cataracts of Emery-Little grade III and below.

Methods

A total of 142 patients were randomly assigned to either the 180° nuclear flip group (n = 71) or the conventional endocapsular phacoemulsification group (n = 71).

n = 142 patients

Results

average total time to remove the cataract lens using the flip method - shorter is better

Flip group (TPT)

43.75s

Conventional group (TP

58.45s

More results

There were no posterior capsule rupture cases in the flip group, whereas there was one case (1.4%) in the traditional group.

At 28 days postoperatively, the mean endothelial cell loss rate of the flip group (3.7%) was lower than that of the conventional group (4.9%), although this difference did not reach statistical significance.

Conclusion · 1 of 2

The 180° nuclear flip technique is a safe, efficient, and effective method for managing cataracts of grade III hardness and below.

Conclusion · 2 of 2

It may help reduce the risk of complications, improves intraoperative stability by creating a more spacious operating field, and significantly reduces phacoemulsification time. Video available for this article.
