Clinical Curative effect on aspheric keratectomy excimer laser subepithelial keratomileusis(LASEK) for high myopic of thin corneal

Abstract

Obiective To discuss the clinical curative effect of corneal wavefront-guided combining Q-value guided aspheric keratectomy excimer laser subepithelial keratomileusis(LASEK)of ORK-CAM (Optimized Refractive Keratectomy Customized Ablation Manager,ORK-CAM)in treatment for high myopia with thin cornea.Methods Corneal wavefront-guided combining Q-value guided aspheric keratectomy excimer 1 aser subepithelial keratomileusis(LASEK)of ORK-CAM were used in 76 eyes of 49 patients who were high myopia with thin cornea.UCVA(uncorrected visual acuity,UCVA),optometry,level of haze were observed at 2,4 weeks,3,6 months post-operation.Topography,wavefront aberration,Visual contrast sensitivity and investigation of Satisfaction were reviewed 6 months post-operation.Results BSCVA(best spectacle-corrected visual acuity,BSCVA)was 1.10+0.12 preoperative,and UCVA was 1.12+0.17 at 6 months after operation.Simk(sinulated keratometry,simk)of equivalent value,Coma-like,spherical-like,RMSg(root of mean square of general aberration)inereased-13.5%,93.87%,172.22%,23.81%,43.28% postoperative respectively.Compared with prooperation,these data all had statistical significance.92.11% eyes of postoperative topography were central uniform type.43.87% patients were satisfied with the quality of vision.Conelusious Corneal wavefront-guided combining Q-value guided aspheric keratectomy excimerl aser subepithelial keratomileusis(LASEK)of ORK-CAM for high myopia have a stable vision after 3 months of surgery,and better than preoperative UCVA.The RMSg,Sqrah increased a little 6 months after operation.The rate of Glare,Bad night vision was low.Corneal wavefi'ont aberration-guided aspheric keratectomy excimer,ORK-CAM have a good clinical curative effect.
