摘　　要：目的观察白内障超声乳化联合负度数Sensar AR40e折叠式人工晶状体植入治疗超高度近视合并白内障的临床疗效。方法对超高度近视合并白内障行超声乳化白内障吸除联合负度数Sensar AR40e人工晶状体植入术的35例(59只眼)患者进行回顾性研究,记录术前眼轴长度,观察手术并发症和术后视力、屈光度数及其与预期屈光度数的偏差值(屈光度数偏差值)。术后随访时间为3～12个月。结果术前平均眼轴长度为31.34mm。术后最佳矫正视力≥0.2共49只眼(83.05%),≥0.5者共26只眼(44.07%)。术后屈光度数偏差值<±1.00 D共31只眼(52.54%),<±2.00 D共52只眼(88.14%)。术中仅1只眼晶状体后囊膜破裂;术后6只眼晶状体后囊轻度混浊,随访期间无视网膜和脉络膜脱离。结论白内障超声乳化联合负度数人工晶状体植入术治疗白内障合并超高度近视眼安全、有效。植入负度数后房型人工晶状体既可以维持眼内组织的稳定性,又可同时进行屈光矫正。Objective To evaluate the clinical effects of phacoemulsification and implantation of negative-power posterior chamber intraocular lenses [ IOL） in patients with extreme myopia and cataract. Methods 35 patients （ 59 eyes ） received phacoemulsification and and implantation of negative-power Sensar AR40e IOL. Preoperative axial length, postoperative visual acuity and refractive error were recorded. Intraoperative and postoperative complicationswere observed. The follow-up time is from 3 to 12 months. Results The mean preoperative axial length is 31.34 mm. Best corrected visual acuity achieved 0.2 or better in 49 eyes （ 83.05 % ） and 0.5 or better in 26 eyes （44.07 % ）. Of the 59 eyes, 31 eyes （ 52. 54% ） were within 1.00 diopter（D） of refactive error and 52 eyes （ 88.14% ） were within an error of 2.00 D. Only 1 eye has posterior capsule rupture. 6 eyes developed posterior capsule opacification. No retinal or choroidal detachment was seen during the follow-up. Conclusion It is safe and effective for phacoemulsification and implantation of negative-power Sensar AR40e IOL in patients with extreme myopia and cataract. Negative power Sensar AR40e IOL can especially improve the stability of the tissue in eyeball. Meanwhile it can correct the refractive errors.
