目的:探讨虹膜夹固定型前房人工晶状体植入术治疗高度近视的疗效和安全性。方法:对7例13眼高度近视患者行虹膜夹固定型前房人工晶状体植入术。术后观察患者视力、眼压、角膜内皮细胞计数,瞳孔活动度、人工晶状体的位置及并发症。结果:患者13眼均成功植入人工晶状体。术后7d裸眼视力优于术前最佳矫正视力10眼(77%);术后12mo,裸眼平均为0.6±0.2,优于术前最佳矫正视力0.4±0.1,差异有统计学意义(P<0.05)。术后眼压和角膜内皮细胞计数与术前对比无统计学意义(均P>0.05);人工晶状体光学部分位置居中,所有患者的瞳孔对光反应均正常,所有患者无白内障、角膜内皮失代偿等并发症,有2眼于术后3～4wk出现糖皮质激素性青光眼,仅1例于术后6mo发生单眼视网膜脱离。结论:虹膜夹固定型前房人工晶状体植入术是一种矫正高度近视安全有效地手术方式。但远期效果需进一步观察。

AIM:To evaluate the efficiency,security after implantation of iris-clawed anterior chamber intraocular lens(IOL) for the correction of high myopia. METHODS:Iris-clawed anterior chamber IOL were implanted for seven cases of patients with high myopia (13 eyes).After the following up for 12 months,visual acuity,intraocular pressure,corneal endothelial cells counting,the activity of the pupil,the position of IOL and complications were observed. RESULTS:The implantation was successfully performed in all of 13 eyes.After the following up for 7 days,the postoperative uncorrected visual acuity of 10 eyes(77%) was better than the preoperative best-corrected visual acuity.After the following up for 12 months,postoperative average uncorrected visual acuity(0.6±0.2) was better than the preoperative average best-corrected visual acuity (0.4±0.1),there was significant difference between preand post-operation(P<0.05).There was no significant difference between preoperative and postoperative corneal endothelial cells counting,intraocular pressure (all P>0.05).The position of IOL retained center well,the react to light of the patient’s pupils was normal,and complications such as cataract and corneal endothelial decompensation was not found,but two eyes occurred corticosteroid-induced glaucoma after 3-4 weeks,and the simple eye of one case occurred retinal detachment after six months. CONCLUSION:Iris-clawed anterior chamber IOL is an effective,safe operative technique for the correction of high myopia.Follow-up study is still required for the evaluation of long-term results.
