方法：对因白内障合并超高度近视眼行小切口联合负度数人工晶状体植入术的75例98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6～12mo。

结果：术前平均眼轴长度为32.05±1.78mm。术后最佳矫正视力≥0.2者66眼(67.3%)； ≥0.5者43眼(43.9%)，术后屈光度数偏差值<±1.00D者48眼(49.0%)； <±2.00D者78眼(79.6%)。术中后囊膜破裂3眼。术中出现后弹力层部分脱离1例。术后角膜不同程度水肿21眼。术后6mo有13眼出现后囊混浊，经Nd：YAG激光切开后视力恢复。未见发现视网膜脱离、继发性青光眼、黄斑囊样水肿、人工晶状体移位等并发症。术后2眼出现双眼干扰症状，经过3mo后行另一眼人工晶状体植入术，术后症状消除。

结论：手法小切口白内障摘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。

METHODS: Totally 75 cases(98 eyes)with super high myopia and cataract which had underwent small incision combined with negative power intraocular lens implantation were studied retrospectively. Preoperative axial length and postoperative visual acuity, refractive diopter and expected deviation value(refractive deviation)were recorded. Eye conditions operation complications and postoperative were observed. The patients were followed-up for 6 to 12 months.

RESULTS: The mean preoperative axial length was 32.05±1.78mm. Best corrected visual acuity≥0.2 was in 66 eyes, accounting for 67.3%; ≥0.5 in 43 eyes, accounting for 43.9%; the postoperative refractive error <±1.00D was total 48 eyes, accounting for 49.0%; <±2.00D total 78 eyes, accounting for 79.6%. Intra-operative posterior capsular rupture occurred in 3 eyes. Intra-operative posterior elastic layer detachment occurred in 1 cases. The postoperative corneal edema was found in 21 eyes. Postoperative 6 months, posterior capsular opacification was found in 13 eyes, and the visual acuity recovered after Nd:YAG laser cut. No retinal detachment, secondary glaucoma, macular cystoid edema, intraocular lens shift and other complications were found. Two eyes had the symptom of binocular interference post-operation. Three months later, another eye was performed intraocular lens implantation. The symptoms were eliminated post-operation.

CONCLUSION: The manual small incision cataract extraction combined with negative power intraocular lens implantation for cataract with high myopia is safe, effective method.
