Abstract
Small incision cataract surgery, using phacoemulcification offers rapid visual recovery.
Improvements in astigmatic outcomes are now possible by focusing upon and obtaining more accurate preoperative cylinder measurements, careful surgical planning particularly in regard to incision design.
The aim of this work is to study corneal topographic changes after 5.2mm clear corneal incision and posterior chamber 5mm intraocular lens implantation in phacoemulsification.
This study included 16 eyes of 15 patients with senile cataract .The operations were performed in The Ophthalmic Department of Benha University Hospital. The patients were selected randomly from both sexes.
At the end of the follow-up period in 67.5% eyes, the cornea became flatter by 0.67±0.48SD diopeters and steeper by -0.45±0.52SD diopeters in 37.5% of eyes. Flattening at the vertical meridian (the meridian of incision) was 0.65±0.74SD diopeters and steepening at the horizontal meridian was -0.15±0.80SD diopeters. The axis changes in the majority (75%) of eyes were less than 30 degrees.
