有晶状体眼后房型可植入式接触镜矫正高度近视患者18例

目的探讨有晶状体眼后房型可植入式接触镜(ICL)植入术矫正高度近视的有效性及安全性。方法表面麻醉下对18例（32眼）高度近视患者行有晶状体眼后房型ICL植入术，将术后裸眼视力与术前最佳矫正视力对比，术后屈光度、眼压与术前屈光度、眼压进行对比。观察ICL在眼内的位置及有无并发性白内障、继发性青光眼等并发症的发生。结果18例（32眼）术后裸眼视力均达到或超过术前最佳矫正视力，除两例（2眼）术后2?h出现一过性高眼压，1例（1眼）术后10?d出现眼压升高，经局部降眼压对症治疗及停用激素眼药治疗后，眼压恢复正常，其余患者术后眼压均在正常范围内。UBM显示：眼内ICL镜片与晶状体前表面有一定的间隙。随访期间，视力、屈光度、眼压稳定。无并发性白内障，继发性青光眼，视网膜脱离及慢性色素膜炎等发生。结论有晶状体眼后房型ICL植入术安全可靠效果好。

Posterior chamber implantable contact lens for 18 cases of high myopia

To investigate the efficacy and safety　of posterior chamber implantable contact lens (ICL) implantation to correct high myopia in phakic eyes. MethodsUnder topical anesthesia   18 cases (32 eyes)  of high myopia were treated with posterior chamber intraocular lens implantation. Comparisons between post operative uncorrected visual acuity and pre operative best corrected visual acuity, between post operative refraction and pre operative refraction, and between post operative intraocular pressure and pre operative pressure were carried out. ICL′s location and complications such as  cataract and secondary glaucoma were observed. ResultsPost operative uncorrected visual acuity reached or exceeded the preoperative best corrected visual acuity in 18 cases (32 eyes). Except that 2 cases (2 eyes) had a transient high intraocular pressure 2 hours after the operation and 1 case had a high intraocular pressure 10 days after the operation, others were controlled normally. UBM showed that  there was a certain gap between ICL  and the lens. During the follow up period, visual acuity, refraction, and intraocular pressure were stable. No complicated cataract, secondary glaucoma, retinal detachment or chronic meningitis, such as uvitis happened. ConclusionICL posterior chamber intraocular lens implantation in eyes is safe and reliable.
