Abstract Details

Purpose:

To evaluate surgically induced astigmatism (SIA) whit the clear corneal incision on the temporal meridian and variation of intraocular pressure (IOP) with cataract surgery.

Setting:

Bagcilar Education and Research Hospital

Methods:

The retrospective clinical study compromised 126 eyes of 86 patients with a mean age of 76 years, that had cataract surgery without complication performed between 2012-2013 in our clinic. All of them underwent phacoemulsification cataract surgery by the same surgeon through a 2.8 mm temporal corneal incision. Preoperative astigmatism and IOP were compared with 1 month after surgery. Student T test was used to compare mean values.

Results:

Preoperative corneal astigmatism varied from 0.5 to 3.5 diopters with a mean of 1.28 ±0.74. SIA was -0.25 ±0.56 (p<0.001) [-2.00; +1.25]. Preoperative mean axis was 89.35 ±28.81 and postoperative was 81.26 ±34.59. Preoperative mean IOP was 17.45 ±4.28 and postoperative was 12.79 ±3.94, with a mean reduction of 4.66 mm Hg after cataract surgery (p<0.001). There were no statistically significant differences between gender, age or laterality (p>0.05).

Conclusions:

Clear corneal incision on temporal meridian decreased mean corneal astigmatism (-0.25 diopters) [-2.00; +1.25]. There was a statistically significant reduction of IOP 1 month after uneventful phacoemulsification. FINANCIAL INTEREST: NONE
