Abstract Details

Purpose:

To assess the safety in terms of endothelial cell loss in patients who underwent anterior lens capsulotomy using an automated precision pulse capsulotomy (PPC) device (Zepto, Mynosis Inc., Fremont, CA) or by manual continuous curvilinear capsulorhexis (CCC).

Setting:

Hospital Universitario La Paz, Madrid. Spain.

Methods:

This single-center prospective study developed between September 2018 and January 2019 comprised a total of 18 eyes undergoing phacoemulsification cataract removal through a 2.2 mm corneal incision and ophthalmic viscosurgical device (OVD), performing the anterior capsulotomy using a PPC device in 10 eyes (group 1, cases), and manual capsulorhexis in the fellow eye (8 eyes, group 2, controls). Outcomes included intraocular lens (IOL) position, capsulotomy appearance, surgical complications, endothelial cell count and final visual acuity.

Results:

All cases resulted in complete round capsulotomies, with intracapsular and centered IOL fixation, observing no complications intraoperatively. Slit lamp examination at day 1 showed no significant differences in terms of corneal edema and anterior chamber (AC) inflammation, however, one case of early capsular fibrosis at week 1, and cystic macular edema at month 1 were referred in group 1. Endothelial cell count presented a non statystically significant reduction at 1 month follow-up amongst groups, however it showed a significant reduction in group 1 comparing cell count at day 1, week 1 and month 1. Final visual acuity demonstrated no differences.

Conclusions:

Precision pulse capsulotomy is a new method to automate a critical step during cataract surgery, which allows us to perform a perfectly circular capsulotomy in a safe and reproducible way, with no increase in zonular distress, inflammation or endothelial cell loss.
