可植入胶原聚合透镜植入术后早期眼前段观察

目的 观察有晶状体眼可植入胶原聚合透镜（ICL）植入术后早期的眼前段形态.方法 随机选取接受ICL植入术的高度近视37例（65只眼）,测量患者术前、术后1个月和6个月的前房深度、前房角、前房容积、眼压和角膜内皮细胞密度,并对测量结果进行统计学分析.结果 术后前房深度、前房角和前房容积均较术前显著减小,术后1个月和术后6个月相比差异无统计学意义.术后1个月时眼压较术前稍有降低,术后6个月时恢复至术前水平;术后1个月和6个月患眼角膜内皮细胞密度较术前分别降低4.75％和6.87％;术后1个月和6个月ICL拱高分别为（412.61±192.94）m和（365.69±179.75）m,与晶状体无接触.结论 ICL植入术后早期眼前段形态发生显著改变,但随访期内各指标稳定,未引起前房角关闭或眼压升高.仍需对其进行更为长期的临床观察.

Observation of anterior segment after implantation of implantable collamer lens in early stage

Objective To observe the anterior segment after implantation of implantable collamer lens （ICL） in early stage.Methods 65 eyes of 37 patients with high myopia who accepted ICL implantation were enrolled in this study.Anterior chamber volume （ACV）,anterior chamber depth （ACD）,iridocorneal angle,intraocular pressure （IOP） and endothelial cell density were measured at pre-operation,1 month and 6 months after surgery,and measurements were analyzed by statistical analysis.Results After surgeries,the ACD,iridocorneal angles and ACV decreased statistically significantly,and there were no statistical differences between measurements of 1 month and 6 months after surgery; the IOP measured at postoperative 1 month was lower than before and achieved stable state during postoperative 6 months; The endothelial cell density decreased about 4.75％ and 6.87％ respectively at postoperative 1 month and 6 months （P ＜ 0.05） ; The mean central vault were （412.61 ± 192.94） μm and （365.69 ± 179.75） μm respectively at postoperative 1 month and 6 months,the ICLs had no contact with lens.Conclusion In the early period after implantation of ICL,the anterior segment morphology changed significantly,but these indexes were stable and no closure of iridocorneal angle or increasing of IOP were observed in the follow-up 6 months,therefore,long time follow-up is still required.
