Abstract Details

Purpose:

The aim of this work is to compare toric intraocular lens (IOL) implantation, and opposite clear corneal incisions to treat astigmatism during phacoemulsification.

Setting:

Benha University hospitals, Egypt

Methods:

30 eyes of 30 patients were devided into 2 equal groups. 15 eyes were offered phacoemulsification with toric IOL implantation and 15 were implanted spherical IOLs with opposite clear corneal incisions. Postoperative astigmatism and UCVA were measured and compared during week 1 and after 3 months

Results:

The mean preoperative UCVA was 0.11 ± 0.07 in toric subgroup, 0.11 ± 0.08 in OCCI subgroup. The mean preoperative astigmatism was -3 +/-0.67 & -2.75+/- 0.77 respectively. In the 3 months follow up visit the mean for the postoperative UCVA was 0.87±0.19 and 0.63±0.18 for each subgroup respectively. The mean postoperative astigmatism was -0.83+/-0.34& -1.5+/- 0.6 respectively. There was a highly significant statistical difference between the result of UCVA preoperative and the results of UCVA at the first and last postoperative follow up in both groups.

Conclusions:

From our results, it is evident that OCCI are safe, predictable, and effective method for treating pre-existing astigmatism in cataract surgery. However, regression may occur after surgery. Toric IOL implantation has recently become available as a mean of treating astigmatism. Toric IOL implantation was proven to be very effective, stable and safe. FINANCIAL DISCLOUSRE: NONE
