目的 观察和探讨后房型有晶体眼人工晶体植入术治疗高度近视及散光的效果及安全性.方法 后房型有晶体眼人工晶体植入术治疗高度近视及散光28例56眼.术前屈光度(等效球镜)为-7.0～-22.50D,平均(-12.42±3.50)D.散光0.37～6.5D,平均(1.92±1.32)D.所有患者随访3～24个月.术后检查视力、眼压,裂隙灯检查眼前部情况.结果 术后3个月,所有病例术后达到或超过术前最佳矫正视力.等值球镜,0.25～1.50D,平均(0.534±0.408)D.散光度0.25～1.50D,平均(0.564±0.289)D.术后并发症:4例7眼术后早期眼压升高,经降眼甩治疗,3～4天后眼压正常.结论 后房型有晶体眼人工晶体植入术治疗高度近视及散光效果确切,预测性好,手术安全.高度近视,尤其是超高度近视以及角膜薄不适合准分子激光矫正的患者是理想的治疗对象.%Objective To observe and investigate the efficacy and safety of the implantation of phakic posterior chamber intraocular lens (ICL) for high myopia with or without astigmatism. Methods 56 eyes of 28 patients with high myopia were treated with ICL implanta-tion. The range of preoperative myopia diopters was-7.0 to-22. 5D, mean-12.42±3.50 D. Astigmatism ranges 0.37 to 6.5D, mean 1.92±1.32D. All of 56 eyes were implanted ICL successfully and have been followed up for 3 to 24 months. The follow up examination included visual acu-ity, refraction, tonometer, slit lamp examination ,and space between crystal lens and IOL. Results Three months after operation, the uncor-rected visual acuity of every eye was same or better than the pre-operative best corrected visual acuity (BCVA). The refractive diopters were from 0.25 to 1.50D, mean 0.534±0.408D. Astigmatism were 0.25 to 1.50D, mean 0.564±0.289D.complications were secondary glaucoma. 7 eyes of 4 patients had increased intraocular pressure shortly after surgery. After treatment, the intraocular pressure became normal in 3 to 4 days. Con-clusion The phakic posterior chamber IOL was efficacious, predictable and safe. It is suitble for high myopia, especially for patients with thin cornea.
