Objective: To compare the surgically induced astigmatism between superior-right and temporal incision in cases with 3.5 mm clear corneal phacoemulsification surgery.
Material and Methods: 53 eyes of 49 patients who had sutureless clear corneal phacoemulsification surgery with 6.0 mm foldable intraocular lens implantation into the posterior chamber capsular bag were included in this prospective and randomized study. 33 eyes were operated with superior-right incision and 20 eyes were with temporal incision. Surgically induced astigmatism was analyzed with vector analysis method at day 1, 2 and month 1 and 6.
Results: Preoperative astigmatism was found to be 1.1±0.7 diopter in the superior-right incision group and 0.7±0.5 diopter in the temporal incision group by simple keratometric subtraction method. The mean postoperative surgically induced astigmatism by vector analysis at the 1st, 2nd days, 1st and 6th months were respectively 1.84±1.4, 1.78±1.3, 1.24±1.1 and 1.20±1.0 diopter in superior-right incision group and 0.96±0.6, 0.94±0.6, 0.98±1.2 and 0.63±0.6 diopter in the temporal incision group. Surgically induced astigmatism between two groups was significantly different in the postoperative 6 months follow up (unpaired student-t test, p=0.02).
Conclusion: Since phacoemulsification surgery with temporal incision both had less postoperative surgically induced astigmatism and more stabile survey, it was concluded that temporal incision should be preferred to the superior-right incision site.Keywords: Cataract surgery, phacoemulsification, complications, astigmatismTurkiye Klinikleri J Ophthalmol 2005, 14:173-179
