Comparison between femtosecond laser capsulotomy and manual continuous curvilinear digital image guided capsulorrhexis

Abstract

Purpose: To measure and compare size and shape parameters of femtosecond laser capsulotomy with manually continuous curvilinear digital guided capsulorhexis (CCC) and their refractive outcomes. Methods: Laser capsulotomies in 40 eyes of 40 patients were performed using LenSx femtosecond laser device (Alcon, Forthworth, US) and its results were compared with the CCC digital guided carried out in 40 eyes of 40 patients using the Callisto Eye digital image system (Zeiss, Germany). Capsulorhexis circularity, shape and capsule overlap were measured using Adobe Photoshop (Adobe Systems Inc.) and postoperative refraction outcomes were evaluated in both groups. Results: Highly accurate and predictable capsulotomy diameter, size and shape were achieved with femtosecond laser capsulotomy compared with capsulorhexis and showed statistical difference between groups. Spherical equivalent comparison between groups showed no statistical difference.

“…On the other hand, although the new technique claims higher accuracy in achieving perfect capsulorhexis, a few complications such as incomplete capsulotomy, the presence of small anterior capsular tags or even anterior radial tears have been reported [10,11]. This could explain why some surgeons still prefer to dye the anterior capsule to check the outcome of the laser assisted capsulotomy [12].…”
