摘要
目的 探讨有晶状体眼前房型人工晶状体植入术矫正高度近视的有效性和安全性。方法 对 5 1例 92眼高度近视患者行巩膜隧道切口有晶状体眼前房型人工晶状体植入术。平均年龄2 8 14岁 ,术前矫正视力 0 15～ 1 0 ,平均近视度数 (-14 90± 1 1)D ,平均散光度数 (-1 3 8±0 3 )D ,平均植入人工晶状体屈光度数 (-14 82± 1 3 3 )D。结果 术后所有患者裸眼视力提高 ;79眼 (85 87% )裸眼视力≥ 0 5 ;63眼 (68 48% )术后裸眼视力较术前最佳矫正视力提高。术后平均近视度数 (-0 5 4± 0 3 7)D ,平均散光度数 (-0 67± 0 14 )D。术后平均角膜内皮细胞数目为(2 90 5± 2 69)个 /mm2 ,较术前减少了 7 0 2 %。术后平均随访时间 18个月。无严重并发症发生。结论 有晶状体眼前房型人工晶状体植入术是矫治高度近视安全、有效的方法 ,具有术后视力好、并发症少。
Objective To investigate the efficacy and safety of the implantation of phakic anterior chamber intraocular lens to correct high myopia.Methods Phakic anterior chamber intraocular lensimplantation(AC-IOL-PM)through scleral tunnel incision was performed on 92 eyes of 51 high myopic patients.The average age of patients was 28 14 years(18～45 years)old.The preoperative corrected visual acuity was 0 15～1 0.The mean preoperative spherical equivalent and astigmatism was (-14 90±1 1)D and (-1 38±0 3)D respectively.The mean diopter of IOL was (-14 82±1 33)D.Results The uncorrected visual acuity improved in all cases postoperatively,with 79 eyes (85 87%) achieving ≥0 5.After surgery,the uncorrected visual acuity improved in 63 eyes (68 48%) than the mean best corrected visual acuity(BCVA).The mean postoperative shpherical equivalent and astigmatism was (-0 54±0 37)D and (-0 67±0 14)D respectively.The average follow up was 18 months(12～30 months).No severe complications happened.Conclusions The implantation of phakic anterior chamber intraocular lens to correct high myopia is a safe,effective procedure serving as a refractive surgery.It is worth to spread due to good outcome of visual acuity,low incidence of complications,high predictability and stability.
