【摘要】：目的观察有晶状体眼后房型人工晶状体(implantable contact lens,ICL)植入术治疗高度近视的早期临床效果。方法按照拟定的入选标准选取行ICL植入术治疗的高度近视患者48例90眼,术后随访6个月。记录术前、术后各随访时间点的裸眼视力、等效球镜度、低对比度视力、眼压及角膜内皮细胞密度。使用SPSS 19.0软件描述术前术后各指标的分布特征,采用非参数检验对裸眼视力进行手术前后的差异性比较,采用配对t检验对其余各指标进行手术前后的差异性比较。结果 90眼均成功植入ICL。全部患者在随访期中,裸眼视力均达到术前最佳矫正视力,52.2%的眼数超出一行及以上;等效球镜度维持在±1.0 D;低对比度视力术后1个月、3个月、6个月分别为-0.43±0.20、-0.47±0.21、-0.45±0.18,较术前矫正屈光不正后测得值有所提高(P0.05),眼压无明显变化(P0.05),角膜内皮细胞密度较术前减少(P0.05)。对于术后有统计学意义的指标,除低对比度视力在术后3个月达稳定水平外,其余指标均在术后1个月时即达到稳定状态。91.7%的患者对ICL植入术早期效果表示满意,全部患者术后均未出现严重并发症。结论有晶状体眼后房型人工晶状体植入术矫正高度近视在术后早期随访中取得了满意的临床效果。
[Abstract]:Objective to observe the early clinical effect of posterior chamber intraocular lens implantation in the treatment of high myopia. Methods according to the selected criteria, 48 patients (90 eyes) with high myopia treated by ICL implantation were selected. The uncorrected visual acuity, equivalent globular goggles, low contrast vision, intraocular pressure and corneal endothelial cell density were recorded before and after operation. SPSS 19.0 software was used to describe the distribution characteristics of each index before and after operation. Non-parametric test was used to compare the difference of visual acuity before and after operation, and paired t test was used to compare the differences of other indexes before and after operation. Results 90 eyes were successfully implanted with ICL.All the patients were followed up. The number of eyes with uncorrected visual acuity of 52.2% was more than one line or more. The equivalent spherical lens was maintained at 卤1.0 D, and the low contrast visual acuity at 1 month, 3 months and 6 months after operation was -0.43 卤0.20 卤0.47 卤0.21 卤0.45 卤0.18, respectively, which was higher than that measured after correction of refractive errors before operation (P 0.05), but the intraocular pressure did not change significantly (P 0.05), and the density of endothelial cells decreased compared with that before operation. P0.05. for the postoperative indexes, there is a significant difference between the two groups. Except that the low contrast visual acuity reached stable level 3 months after operation, the other indexes reached stable state at 1 month after operation. 91.7% of the patients expressed satisfaction with the early effect of ICL implantation. Conclusion posterior chamber intraocular lens implantation for correction of high myopia has achieved satisfactory clinical results in early postoperative follow-up.
