Abstract Details


To evaluate manual arcuate keratotomy (AK) procedures for the correction of postkeratoplasty astigmatism


King Khaled Eye Specialist Hospital, Riyadh, Saudi Arabia


53 eyes (51 patients) were treated with manual AK for post-keratoplasty astigmatism. The main outcome measures included preoperative and postoperative manifest refraction, uncorrected and corrected distance visual acuity (UDVA, CDVA), corneal topography and complications.


preop- (0.87�Â�±0.35) and post-operative UDVA (0.93�Â�±042) were comparable (p=0.535). CDVA improved from 0.28�Â�±0.15 preoperative to 0.23�Â�±0.19 at last postoperative visit (0.074). The mean preoperative refractive cylinder was 6.38�Â�±3.73, decreasing to 5.06�Â�±2.06 after manual AK procedures. Mean change in refractive cylinder was -1.10�Â�±4.11. Perforation, overcorrection and regression occurred in 1 eye (1.9%; macro-perforation), 7 eyes (13.21%) and 8 eyes (15.09%) respectively. Additionally, severe ectasia occurred in 1 eye (1.9%)


Manual AK procedure is safe and effective procedure and postoperatively resulted in better UCVA, BCVA, refractive cylinder and keratometric astigmatism
