摘要
目的评价眼前节处理系统个体化切削治疗复杂屈光不正的临床疗效。方法对32例(63眼)复杂屈光不正患者应用眼前节处理系统的地形图引导,进行个体化切削,于术前、术后1周、1个月、3个月进行裸眼视力、最佳矫正视力、眼压、眼前节分析系统的角膜曲率、角膜厚度及角膜地形图检查,以及主观视觉质量调查。结果术后裸眼视力均优于术前最佳矫正视力,术前角膜散光(2.46±0.36)D,术后残留(0.28±0.14)D:角膜切削量节省10%左右,有效增加了切削后角膜的厚度;主观视觉质量调查无不良反应;术后角膜地形图检查无偏中心现象。结论眼前节处理系统个体化切削治疗复杂屈光不正安全、有效。
Objective To determine whether topog- raphy-guided custom ablation produces acceptable outcomes in the treatment of complex refractive er- rors. Methods Topography-guided customized cor- neal ablations were performed in 32 patients (63 eyes) with complex refractive errors. Corneal surface regularity index, surface asymmetry index, asymme- try component, corneal and ocular higher-order aber- rations, uncorrected visual acuity, and best spectacle- corrected visual acuity were analyzed during the fol- low-up. Results Uncorrected visual acuity was bet- ter after operation than corrected visual acuity before operation. Astigmatism was significantly lower after operationl ( 0.28 _+ 0. 14 ) D ] than before operation E (2.46 + 0.36 ) D ]. The quantity of cornea ablation was saved by 10% or so. There were no adverse re- actions in subjective visual quality. No eccentric phe- nomena were discovered in topography after opera- tion. Condusion Topography-guided custom abla- tion is safe and effective in the management of com- plex refractive errors.
