高度近视白内障超声乳化及人工晶状体植入36例

目的观察高度近视白内障超声乳化及人工晶状体植入的疗效。方法对36例(56眼)高度近视白内障行超声乳化及人工晶状体植入术。平均眼轴28.06mm,平均曲率44.02D,平均IOL测算值 13.0D,实际植入IOL平均值 14.0D,术后屈光状态平均为-2.25D。术后随访3～18(平均12)月。结果术后矫正视力<0.05者2眼(4％);0.05-0.25者4眼(7％);0.3—0.5者16眼(28％);0.5-1.0者34眼(61％)。结论术前反复测量眼轴长度、精确计算IOL度数是提高高度近视眼并发白内障患者术后视力的重要因素。高度近视所致眼底病变是影响术后视力的主要原因,后囊破裂是造成术后视网膜脱离的最危险因素。

Efficacy of Phacoemulsification and IOL Implantation in Cataract Complicated with High Myopia

Objective To observe the efficacy of cataract emulsification and intraocular lens (IOL) implantation in high myopia. Methods In 36 cases of high myopia (56 eyes), cataract was treated with phacoemulsification and IOL implantation. On average, the axis was 28.06mm long, the curvature being 44.02D, the average value of the estimated IOL and that of the implanted IOL being 13.0D, and 14.0D respectively, the postoperative refraction being -2.25D. The follow-up was 3 to 18 months (12 months on average). Results Postoperatively, the corrected vision was lower than 0.05 in 2 eyes (4%), between 0.05 and 0.25 in 4 eyes (7%), between 0.3 and 0.5 in 16 eyes (28%) and between 0.5 and 1.0 in 34 eyes (61%). Conclusion Accurate measurement of axial length and calculation of IOL degree before operation are crucial for better postoperative vision in myopic cataract. Fundal change due to high myopia largely determines postoperative vision and ruptured capsula is the most dangerous factor resulting in postoperative retinal detachment.
