Abstract Details

Purpose:

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

Setting:

King Khaled Eye Specialist Hospital, Riyadh, Saudi Arabia

Methods:

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.

Results:

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%)

Conclusions:

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