Abstract Details


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


Bagcilar Education and Research Hospital


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.


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).


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
