Phacochop Versus Stop and Chop: Comparative Analysis of Phaco Parameters and Visual Acuity
Narrative Responses:
Purpose
To make a comparison between intraoperative and postoperative parameters of phaco-chop and stop-and-chop nucleotomy techniques.
Methods
A prospective study of 84 consecutive cases of phacochop(group1) and 63 consecutive cases of stop-and- chop(group2). The following variables were considered: preop VA, central corneal thickness, degree of nuclear sclerosis, axial length, anterior chamber depth,effective phaco time,US time, Percentage phaco power(%),corneal edema, VA 1day,1week, 1month post operatively
Results
The effective phaco time, US time, Percentage phaco power(%) was significantly less in group1, The visual rehabilitation was significantly faster in the first day & and on the first week post operatively in group1
Conclusion
The phaco-chop technique is safer to the corneal endothelium as less ultrasonic energy was used. This accelerated the functional healing and protected the surrounding intraocular tissue
