Capsulaser In Cataract Surgery: A New Era Of Precision And Safety

This study evaluated the efficacy and safety of performing capsulorhexis using the CAPSULaser compared to the traditional manual method 

 Magrabi Eye Hospital in Jeddah, Saudi Arabia

This prospective, randomized, non-masked study involved 200 patients divided into two groups:  group A (manual continuous curvilinear capsulorhexis, CCC) and group  B (laser-assisted CCC),  The manual CCC aimed for a diameter of 5.5 mm, while the laser CCC targeted 5.2 mm, verified via photomicroscopy using the same caliper device. all types of cataract were included. Surgical duration was recorded both for the entire procedure and specifically for the capsulotomy. the outcome measures were the duration of the capsulotomy and the predictability of the size and centration of the capsulorhexis

The diameter of the capsulorhexis was meticulously determined , both manually and with the aid of CAPSULaser,  Instances of decentered capsulorhexis were noted in 15 patient from group A and two patients from groupB with the degree of decentration confined within a 1.5 mm range in 2 cases. In the B groups, there was an occurrence of incomplete capsulorhexis, presenting a 1 to3  clock hour gap, which was seamlessly completed without extending the duration of the procedure.  

The application of CAPSULaser in cataract surgery demonstrates ease of use and appropriateness across various levels of surgical expertise, providing a method for achieving controlled and accurately centered capsulorhexis. This approach maintains a safety profile comparable to conventional surgical techniques. However, its effective implementation requires specific anatomical conditions: a minimum pupil diameter of 6 mm, a sufficiently deep anterior chamber, and a cornea with clear transparency.
