Zyoptix波前引导的LASIK治疗近视的临床研究

目的:探讨Zyoptix波前引导的LASIK治疗近视眼的疗效,并对有虹膜识别波前引导的LASIK、无虹膜识别波前引导的LASIK及普通LASIK进行疗效比较。方法:对216例(384眼)接受Zyoptix波前引导的LASIK的患者其中有虹膜识别161例(291眼)、无虹膜识别5例(93眼)与同期接受普通LASIK患者304例(572眼)进行疗效比较。结果:波前引导的两组与普通LASIK术后偏中心眼数(χ2检验:P<0.01)、夜视力(t检验:P<0.01)均有显著差异。术后视力比最佳矫正视力提高1行的患者,Zyoptix波前引导LASIK的两组110眼(28.6%),普通LASIK为99眼(17.3%),比较有统计学意义(χ2检验:P<0.05)。结论:Zyoptix波前引导的LASIK在矫正视力的同时提高视觉质量。

Wavefront-guided laserin situkeratomileu-sis for myopia

·AIM:To evaluate the clinical results of wavefront-guided laser in situ keratomileusis(LASIK)surgery in the treatment of myopia..METHODS:In our study,216 cases(384 eyes)underwent Zyoptix wavefront-guided LASIK,including 161 cases(291 eyes)with iris identification and 55 cases(93 eyes)without iris identification;while 304 cases(572 eyes)underwent conventional LASIK surgery.The clinical results were compared between two groups..RESULTS:The number of eyes which had pupil center shift and night vision were significantly different between Zyoptix wavefront-guided LASIK group and conventional LASIK group(P<0.01).With regard to patients whose postoperative vision was better(moving up one line)than preoperative best corrected visual acuity,there were 110 eyes(28.6%)in Zyoptix wavefront-guided LASIK group and there were 99 eyes(17.3%)in conventional LASIK group.There was statistically significant difference between two groups(P<0.05)..CONCLUSION:Zyoptix wavefront-guided LASIK surgery may improve the visual quality as well as correct the visual acuity..
