Purpose: To investigate the refractive outcomes after arcuate keratotomy for astigmatism.Setting: Uludag University, Faculty of Medicine, Department of Ophthalmology, Bursa, Turkey.Method: Sixteen eyes of 11 patients with astigmatism had arcuate keratotomy using the Terry astigmatome. The mean age of the patients was 36 years ± 10 (SD). All patients received preoperative and postoperative ophthalmic examinations consisting of best spectacle-corrected (BSCVA) and uncorrected (UCVA) visual acuities, corneal topography, and ultrasonic pachymetry. Surgery was performed using topical anesthesia of oxybuprocaine 0.1% eyedrops. The Terry astigmatome was selected by the mean paracentral (estimated incision area) corneal thickness. All patients received topical ofloxacin 0.3% and topical diclofenac 0.1% eyedrops postoperatively.Results: The mean corneal astigmatism was −4.0 ± 1.1 diopters (D) (range −2.2 to −6.0 D) preoperatively and –1.8 ± 0.8 D (range −0.6 to −3.0 D) postoperatively. The mean surgically induced corneal astigmatism was 2.5 ± 0.6 D. The mean UCVA (logMAR) was 0.74 ± 0.25 preoperatively and 0.18 ± 0.23 1 week postoperatively, and the mean BSCVA (logMAR) was 0.19 ± 0.24 and 0.19 ± 0.23, respectively. There were no intraoperative or postoperative complications.Conclusion: Arcuate keratotomy using the Terry astigmatome was a safe and reliable treatment for corneal astigmatism.
