목적 : To compare the visual and refractive outcomes of wavefront-optimized (WFO), topography-guided (utilizing the protocol approved by US Food and Drug Administration; TG), and topography-modified refraction (TMR) Laser subepithelial keratomileusis(LASEK) surgery for myopia and myopic astigmatism. 방법 : In this retrospective study included patients who underwent WFO-LASEK, TMR-LASEK, and conventional TG-LASEK procedure with the same refractive platform (ContouraTM Vision software and WaveLight® EX500 excimer laser) to correct myopia and myopic astigmatism from July 2017 to September 2018. We measure and analysis pre- and post-operatively for following parameters: uncorrected distance visual acuity(UDVA), corrected distance visual acuity (CDVA), manifest spherical and cylindrical refraction, and corneal topography(Topolyzer VARIO). Follow-up visits were conducte for at least 6 months. 결과 : 6 months postoperatively, UDVA was -0.02 ± 0.08, -0.04 ± 0.08, and -0.02 ± 0.09 in WFO, TG, and TMR groups, respectively (p=.424). Postoperative high order aberrations including coma, SA were increased in all groups compared with preoperative values except trefoil. Residual cylindrical refractive error in TMR group was significantly larger than those in TG or WFO groups (p=.007). When we performed the Alpins vector analysis for astigmatism change, magnitude of error and correction index were significantly higher in TMR compared with FDA or WFO (p=.007, p=.001). 결론 : Although WFO-, FDA- and TMR-LASEK for myopia and myopic astigmatism gave safe and excellent visual outcomes, TMR resulted in more overcorrected as well as higher cylindrical refractive error compared with WFO and FDA protocols. |
