To evaluate the efficacy, safety and stability of posterior chamber phakic intraocular lens (PIOLs) implantation for the correction of high myopia.
Thirty-nine eyes of twenty patients with high myopia (between -11.75 and -25.75 diopters) had a posterior chamber PIOL (Staar ICL) implanted. During 6 - 48 months' follow-up, visual acuity, refraction, intraocular pressure (IOP), corneal reaction and space between crystal lens and intraocular lens (IOLs) were tested.
Successful implantation was achieved in all patients. Visual acuity without correction greater than 0.5 was found in 34 eyes at 1 day and 3 months postoperatively. Thirty-five eyes maintained a low negative power of refraction (-1.42 +/- 1.32 doipters), which did not prevent the patients from most of their daily activities. During 3 - 48 months' follow-up, refraction was stable and no cornea edema and glaucoma was found. Two eyes of one patient had corticosteroid glaucoma and another eye showed cataractogenesis under anterior capsular membrane.
Posterior chamber PIOL implantation is predictable, safe, and effective in the correction of high myopia, and its indications should be carefully selected.
评估后房型有晶状体眼人工晶状体（PIOL）植入矫正高度近视的有效性、安全性和稳定性。
对20例高度近视患者（-11.75至-25.75屈光度）的39只眼植入后房型PIOL（Staar ICL）。在6至48个月的随访期间，检测视力、屈光、眼压（IOP）、角膜反应以及晶状体与人工晶状体（IOL）之间的间隙。
所有患者均成功植入。术后1天和3个月时，34只眼的裸眼视力大于0.5。35只眼维持低负球镜度数（-1.42±1.32屈光度），这并不妨碍患者进行大部分日常活动。在3至48个月的随访期间，屈光稳定，未发现角膜水肿和青光眼。1例患者的2只眼出现皮质类固醇性青光眼，另1只眼在前囊膜下出现白内障形成。
后房型PIOL植入矫正高度近视具有可预测性、安全性和有效性，但其适应证应谨慎选择。
