摘要
目的 探讨超声乳化白内障吸除负度数人工晶状体植入术治疗白内障合并超高度近视眼的临床疗效。方法 对因白内障合并超高度近视眼行超声乳化白内障吸除负度数人工晶状体植入术的89例(126只眼)患者进行回顾性研究,记录术前眼轴长度和术后视力、屈光度数及其与预期屈光度数的偏差值(屈光度数偏差值),观察手术并发症和术后眼部情况。术后随访时间为6～25个月。结果 术前平均眼轴长度为32 45mm。术后最佳矫正视力≥0 2共106只眼(84 1%),≥0 5者共69只眼(54 8%)。术后屈光度数偏差值<±1 00D共71只眼(56 3%),<±2 00D共114只眼(90 5%)。术中仅1只眼晶状体后囊膜破裂;术后28只眼出现双眼干扰症状;后发性白内障15只眼,6只眼行激光晶状体后囊膜切开术;无视网膜和脉络膜脱离者,无眼压升高者。结论 超声乳化白内障吸除负度数人工晶状体植入术是治疗白内障合并超高度近视眼安全、有效的方法。
Objective To evaluate the clinical effects of phacoemulsification and the negative power of intraocluar lens implantation in patients with extreme myopia and cataract Methods 89 patients (126 eyes) received phacoemulsification and a negative power intraocluar lens implantation Preoperative axial length, postoperative visual acuity and refractive error were recorded Intraoperative and postoperative complications were observed The follow up time is from 6 to 25 months Results The mean preoperative axial length is 32 45 mm Best corrected visual acuity achieved 0 2 or better in 106 eyes (84 1%) and 0 5 or better in 69 eyes (54 8%) Of the 126 eyes, 56 3% were within 1 00 diopter (D) of refactive error and 90 5% were within an error of 2 00 D Only 1 eye has posterior capsule rupture 28 eyes had binocular disturbances 15 eyes developed posterior capsule opacification and 6 eyes were performed neodymium:YAG laser posterior capsulotomy No retinal or choroidal detachment or pressure improvement was seen during the follow up Conclusion It is safe and effective for extreme myopia with cataract to implant a negative power intraocular lens after phacoemulsification
