摘要
目的探讨有晶状体眼AcrySofCACHETM人工晶状体（PIOL）植入术治疗高度近视的有效性、安全性、可预测性、稳定性及患者满意度。方法前瞻性研究。选取2012年1月至2013年2月于山西省眼科医院就诊的高度近视患者共12例（22眼），年龄（28．2±5．9）岁，术前等效球镜度（SE）为-17．25—6．50D，平均（-11．97±3．03）D。22眼行PIOL植入术后1d、1个月、3个月、6个月、1年进行随访，对比观察术前及术后各时间点患者视觉效果及安全性参数。观察指标包括视力（裸眼视力、最佳矫正视力、近视力）、屈光度、眼压（10P）、角膜内皮细胞计数、对比敏感度、手术并发症，以前节OCT测量PIOL位置，前节照相测量PIOL旋转度及问卷调查患者满意度。不同时间点间各指标差异采用重复测量设计的方差分析进行比较。结果随访期间各时间点所有患眼实际SE与预期SE差值在±1D以内。其中20眼实际SE与预期SE差值在±0．5D以内。术后各时间点安全性指数分别为1.31、1.36、1．34、1．41、1．31；有效性指数分别为1．23、1．28、1．22、1．23、1．31。中央区角膜内皮细胞计数累计丢失率分别为1．69％±2．2％、2．25％±3．15％、4．32％±3．04％、4．27％±3．52％、3．82％±2．15％。患眼术前最佳矫正近视力为5．0±0．2，10P为（14．6±3．0）mmHg（1mmHg=0．133kPa），二者术后各时间点与术前相比差异无统计学意义。术后1个月时前节OCT测量PIOL光学区中心及边缘与角膜内皮间垂直距离分别为（1．96±0．25）mm（〉1．5mm）、（0．99±0．08）mm（〉0．8mm），与自然晶状体间垂直距离分别为（1．36±0．22）mm（〉1．0mm）、（0．94±0．09）mm（〉0．8mm）。随访过程中，11眼PIOL位置稳定，6眼顺时针旋转，5眼逆时针旋转，6眼旋转大于15°。与术前相比，术后3个月内各空间频率对比敏感度均明显提高，�
Objective To evaluate the efficacy, safety, stability and predictability of the AcrySof CACHETTM phakic intraocular lens （PIOL） for the correction of high myopia. Methods In this prospective study, 12 patients （22 eyes） who ranged in age from 19 to 40 with high myopia at -17.25-6.50 （-11.97±3.03） diopters （D） were implanted with angle-supported phakic intraocular lenses from 2012 January to 2013 February. Visual acuity, refraction, intraocular pressure, corneal endothelium, PIOL position, contrast sensitivity, glare sensitivity, surgical complications and poor visual symptoms were assessed preoperatively and 1 day, 1 month, 3 months, 6 months and 1 year after treatment. The repeated measures ANOVA was used for statistical analysis. Results The mean manifest refraction at the one-year follow-up was within ID of the attempted correction in 22/22 eyes and 20/22 eyes were within 0.5 D of the attempted correction. At 1 day, 1 month, 3 months, 6 months and 1 year postoperatively, the mean safety indexes were 1.31, 1.36, 1.34, 1.41, 1.31 and the mean efficacy index was 1.23, 1.28, 1.22, 1.23, 1.31. The differences in near vision and intraocular pressure were not statistically significant at any time point. The mean loss of corneal endothelium was 1.69%±2.2%, 2.25%±3.15%, 4.32%±3.04%, 4.27%±3.52%, 3.82%±2.15% at 1 day, 1 month, 3 months, 6 months and 1 year postoperatively. The distance from the central and peripheral corneal epithelium to the AcrySot CACHETTM phakic IOL was 1.96±0.25 mna （〉1.5 mm） and 1.36±0.22 mm （〉1.0 mm）, and was 0.99±0.08 mm （〉0.8 mm） and 0.94±0.09 （〉0.8 mm） from the AcrySof CACHETm phakie IOL to the natural lens. An analysis of the results of the steadiness of the PIOL showed that it was stable in 11/22 but 6/22 had a clockwise rotation and 5/22 had a counter-clockwise rotation. Improvements were statistically significant when contrast sensitivity and glare sensitivity were compared preoperatively and postoperatively. The study showed that there was
