Soft-shell cataract surgery technique protects damaged endothelium

Using the soft-shell technique during phacoemulsification protects the compromised endothelium of patients with Fuchs' endothelial dystrophy, according to a study by researchers in Poland.

Dorota Tarnawska, MD, and Edward Wylegala, MD, PhD, investigated the efficacy of the soft-shell technique for clear corneal phacoemulsification cataract surgery in 61 eyes of 54 patients with Fuchs' endothelial dystrophy. They published their results in the November issue of Journal of Cataract & Refractive Surgery.

All patients were implanted with an intracapsular posterior chamber IOL.

Preoperatively, central corneal thickness averaged 549.5 µm, the authors reported.

"The postoperative increase in CCT over preoperative pachymetry measurements remained statistically significant ... throughout the entire follow-up, from the first day to the sixth month after surgery (P < .0001)," the authors said.
