Abstract Details

Purpose:

To evaluate post-surgery induced astigmatism and endothelial cell status.

Setting:

Ophtalmology department, Mohammed VI university hospital, Marrakech, Morocco

Methods:

This is a prospective study involving 27 cataract operated eyes using the technique of MSICS, and collected at the ophthalmology department of Mohammed VI University Hospital of Marrakech over a period of 6 months from August 2018 to March 2019. Specular microscopy and keratometry were performed for each patient preoperatively, on day 1, day 7, 1 month after the operation. The difference in the two results allowed us to determine the induced surgical astigmatism and to assess the state of the endothelial cells by specular microscopy.

Results:

Our study found 80% reverse astigmatism versus 20% direct astigmatism The mean preoperative astigmatism for all patients was 1.25 diopters. The average of postoperative astigmatism was 2.62 diopters. The mean preoperative astigmatism for patients with preoperative direct astigmatism was 1 diopter. The mean postoperative value  was 1.50 diopters. The mean preoperative astigmatism for patients with preoperative reverse astigmatism was 0.75 diopters.  their postoperative mean was 2.08 diopters with extremes of 2 to 2.75 diopters. Regarding specular microscopy, there is no significant difference between the number of cells preoperatively and postoperatively.

Conclusions:

Cataract surgery aims to achieve better visual acuity with a low rate of postoperative astigmatism. The technique of small manual incision cataract surgery (MSICS), retains most of the benefits of "phacoemulsification" with a very low cost on a very high sample.
