摘要
目的评价高度近视白内障超声乳化摘除及后房型人工晶体植入术的疗效。方法对２１例（２８只眼）老年性、并发性和先天性白内障施行巩膜隧道切口超声乳化吸除，通过３．２ｍｍ切口植入折叠式人工晶体，通过５．５ｍｍ切口植入ＰＭＭＡ硬性人工晶体。平均年龄５１．３２岁（２１～７０岁），平均眼轴长（２７．５６±１．２１）ｍｍ（２６．００～３３．４１ｍｍ），平均角膜曲率（４３．３８±１．３６）Ｄ（４２．００～４６．５４Ｄ），平均人工晶体屈光度（＋９．５９±３．６５）Ｄ（＋４．００～＋１５．００Ｄ）。结果术后１天裸眼或矫正视力≥０．５者，占６３．６％；术后１周、１个月及３个月分别为８６．４％、９５．５％及９５．２％；视力≥１．０者，分别为９．１％、３１．８％、５０．０％及５７．１％。结论高度近视白内障超声乳化及后房型人工晶体植入术，具有术后视力恢复快、屈光状态稳定等优点，但眼轴极长者（＞３０ｍｍ），视力恢复较差。
Objective To evaluate the therapeutic effect of phacoemulsification and posterior chamber intraocular lens (IOL) implantation in high myopia. Methods Phacoemulsification with implantation of a foldable IOL or a PMMA rigid IOL was performed on 28 eyes of 21 patients with senile, complicated or congenital cataracts through a 3.2 mm small scleral tunnel incision or through a 5.5 mm incision respectively. The average age of the patients was 51.32 years (21～70 years). The mean axial length was (27.56±1.21) mm (26.00～33.41 mm). The mean keratometry was (43.38±1.36) D (42.00～46.54 D). The mean diopter of IOL was (+9.59±3.65) D (+ 4.00～+15.00 D). Results Postoperatively, the uncorrected or corrected visual acuity 0.5 or better at 1 day, 1 week, 1 month and 3 months was in 63.6%, 86.4%, 95.5% and 95.2% patients respectively; the patients having achieved the best visual acuity of 1.0 or better were accounted for 9.1%, 31.8%, 50.0% and 57.1% respectively. Conclusions Phacoemulsification and the posterior chamber IOL implantation offers the advantages of rapid and better rehabilitation of visual acuity and more stabilization of postoperative astigmatism in patients with high myopia; whereas for eyes with the axial lengths over 30 mm, the recovery of the visual acuity was less satisfactory.
