方法：回顾性分析43例79眼已行ICL或TICL( toric implantable contact lens)近视矫正手术治疗的患者，术后观察1d～2a的视力、屈光状态、眼压、角膜内皮细胞密度、拱高、晶状体和眼底情况等。

结果：所有术眼术后裸眼视力(4.89±0.17)较前(3.49±0.24)显著提高。末次随访， 术后UCVA高于术前BCVA有72眼(91%)，所有患者手术前后BCVA无下降。等效球镜：术前-12.14±4.14D，末次随访-0.43±0.90D。术后1d眼压(14.82±3.46mmHg)与术前(15.59±2.66mmHg)比较差异有统计学意义(P<0.05)，末次随访眼压(15.77±2.36mmHg)与术前比较无明显统计学差异。术后1a拱高(481±219μm)和术后2a的拱高(475±196μm)与术后6mo拱高(502±225μm)相比有所降低。术后6mo，1、2a的角膜内皮细胞密度与术前相比略有降低，角膜内皮丢失率分别为5.9%、6.7%、8.2%。术后随访，有2眼出现晶状体前囊下混浊，经相应处理后，视力无明显影响，尚未发现黄斑出血、视网膜脱离等其他并发症。

结论：ICL植入术矫正高度、超高度近视疗效好且稳定，术后安全性高。通过术前的精确检查和测算、术中的精细操作及术后的严密观察随访可以有效防治并发症。术后出现的拱高下降的情况尚需进一步的观察并分析其影响因素及远期效应。

METHODS: Totally 79 eyes of 43 consecutive patients undergone ICL implantation or toric implantable contact lens(TICL)up to 2a postoperative were retrospectively analyzed. Visual acuity, refraction, intraocular pressure(IOP), average cornea endothelial cell density(ECD), central vault of the ICL and slit-lamp findings, etc. at 1d～2a after operation were observed.

RESULTS: The uncorrected visual acuity(UCVA)of all eyes was significantly improved from preoperative 3.49±0.24 to postoperative 4.89±0.17. Best corrected visual acuities(BCVA)didn't decline after operation and 91%(72 eyes)of UCVAs were better than preoperative BCVAs. The preoperative spherical equivalent was -12.14±4.14 diopters(D)while it was -0.43±0.90D at last follow-up. The difference on IOP at 1d after operation(14.82±3.46mmHg)and preoperative(15.59±2.66mmHg)had statistical significance(P<0.05), while there was no significant difference between last follow-up(15.77±2.36mmHg)and preoperative. The vaults of 1a(481±219μm)and 2a(475±196μm)after operation decreased comparing with that of 6mo(502±225μm). And the ECD of 6mo, 1 and 2a after operation slightly decreased comparing with that of preoperative. The corneal endothelial loss was 5.9%, 6.7%, 8.2% respectively. No severe complications occurred expect that 2 eyes appeared anterior lens capsules had limited opacities and the visual acuities didn't degrade with dispose in time. Other complications such as macular hemorrhage, retinal detachment, etc. were not found.

CONCLUSION: After 2a of follow-up,ICL implantation has good visual and refractive results with excellent biocompatibility and few adverse reactions. By accurate preoperative examination and measurement, intraoperative fine operation and close observation of postoperative follow-up, the complications can be effectively prevented. It still needs further observation and analysis of the cause and long-term effects of postoperative vault decline.
