IOL Master指导下行多焦点人工晶状体植入术后的屈光状态研究

Research of refraction of eyes with multifocal intraocular lens implantation under the guidance of IOL master

目的:研究非接触光学相关生物测量仪(IOL Master)指导下行白内障超声乳化联合衍射型非球面多焦点人工晶状体植入术后的患眼屈光状态。方法:选取我院单纯性老年性白内障患者68例84眼,术前常规检查,以IOL Master确定人工晶状体度数,行白内障超声乳化术后联合植入Tecnis AMO00衍射型非球面多焦点人工晶状体。术后3mo随访,记录患者术后视力,以综合验光仪检查患者术后屈光状态并记录。结果:近视36眼,远视48眼,球镜和柱镜度数均在-0.50～+0.50D之间,无明显屈光不正。术后裸眼远视力≥0.8者64眼(76%),最佳矫正远视力≥0.8者77眼(92%),裸眼近视力≥0.8者58眼(69%),最佳矫正近视力≥0.8者74眼(88%),中间距离视力≥0.8者58眼(69%)。结论:衍射型非球面多焦人工晶状体能提供良好的全程视力,在IOLMaster指导下更能精确选择度数,患者术后无明显屈光不正,视觉满意度高。

AIM： To research the refraction of eyes after phacoemulsification of cataract and diffractive aspheric multifocal intraocular lens （ IOL） implantation under the guidance of IOL master. METHODS： Totally 68 patients （84 eyes） with age- related cataract were selected. Routine preoperative examinations were completed, and IOLs were determined under the guidance of IOL master. All the patients underwent phacoemulsification of cataract and multifocal IOL （ Tecnis AMO00） implantation. 3 months later, postoperative visual acuity and the refraction （according to the integrated refractometer ） of patients were observed. ~ RESULTS; The refraction types of these 84 eyes included 36 myopia and 48 hyperopia, with spherical and cylindrical diopter between -0.5D to ＋0.5D. No significant refractive error was detected. There were 64 eyes （76%） with postoperative uncorrected distance visual acuity ≥ 0.8, 77 eyes （92%） with best- corrected distance visual acuity I〉0.8, 58 eyes （69%） with uncorrected near visual acuity ≥ 0.8, 74 eyes （88%） with best- corrected near visual acuity I〉 0. 8, 58 eyes （69%） with intermediate visual acuity ≥0.8. CONCLUSION： Diffractive aspheric multifocal IOL provides a high level of full vision, and will be more accurately selected under the guidance of IOL master. No significant refractive error was detected after surgery, and patients were much satisfied.
