摘要

目的评价前提肌切除术（ALR）前后人工晶状体度数计算和眼生物特征参数的差异。方法本前瞻性研究纳入了行ALR手术的渐进性上睑下垂患者。术前、术后3、6个月分别获得眼部生物特征参数。结果选取45例上睑下垂患者，其中25眼仅行上睑切除术，20眼同时行上睑切除术。术后3个月平均角膜曲率（Km）值较术前显著下降（P = 0.026）， 3 ~ 6个月无变化（P = 0.4）。术前平均MRD-1水平为0.86±1.1 mm，术后3个月为3.4±0.9 mm，术后6个月为3.45±1 mm （P = 0.0001）。针对斜视的平均IOL功率在术后3个月增加（P = 0.041）， 3 ~ 6个月无变化（P = 0.2）。6个月后MRD-1水平与K1、K2、Km呈负相关(r: -0.171, P: 0.02；r: -0.334, P: 0.04；r: -041, P: 0.001)，而6个月后MRD-1水平与IOL度数呈正相关（r: 0.348, P: 0.04）。术后6个月，纯alr患者的平均Km、IOL度数和MRD-1水平与纯alr患者比较差异无统计学意义（P值分别为0.2、0.07、0.32）。结论上睑下垂术后角膜度数变化会影响人工晶状体的度数，这种变化在术后3个月趋于稳定。角膜测量已被证明与术后眼睑位置有关。

Change in intraocular lens power calculation results after ptosis surgery

Purpose

To evaluate the difference between intraocular lens power calculation and ocular biometric parameters before and after anterior levator resection surgery (ALR).

Methods

In this prospective study, patients with involutional ptosis who underwent ALR surgery were included. Ocular biometric parameters were obtained preoperatively and 3 and 6 months postoperatively.

Results

Forty-five patients with ptosis were selected for the study, 25 eyes had only ALR surgery, and 20 eyes had both ALR and upper lid blepharoplasty. The mean keratometry (Km) value significantly decreased from the preoperative value at 3 months postoperatively (P = 0.026) and did not change between 3 and 6 months (P = 0.4). The mean preoperative MRD-1 level was 0.86 ± 1.1 mm, 3.4 ± 0.9 mm at 3 months, and 3.45 ± 1 mm at 6 months postoperatively (P = 0.0001). The mean IOL power targeting emmetropia increased at 3 months postoperatively (P = 0.041) and did not change between 3 and 6 months (P = 0.2). There was a negative correlation between MRD-1 level, K1, K2 and Km after 6 months (r: –0.171, P: 0.02; r: –0.334, P: 0.04; r: –041, P: 0.001 respectively), whereas there was a positive correlation between MRD-1 level and IOL power after 6 months (r: 0.348, P: 0.04). The mean Km, IOL power and MRD-1 levels were not statistically different between ALR-only patients and ALR-blepharoplasty patients at 6 months postoperatively (P: 0.2, 0.07, 0.32 respectively).

Conclusion

Ptosis surgery can affect IOL power postoperatively due to keratometric changes, and these changes stabilize at 3 months after surgery. Keratometric measurements have been shown to be related to postoperative eyelid position.

期刊介绍： The Journal français d''ophtalmologie, official publication of the French Society of Ophthalmology, serves the French Speaking Community by publishing excellent research articles, communications of the French Society of Ophthalmology, in-depth reviews, position papers, letters received by the editor and a rich image bank in each issue. The scientific quality is guaranteed through unbiased peer-review, and the journal is member of the Committee of Publication Ethics (COPE). The editors strongly discourage editorial misconduct and in particular if duplicative text from published sources is identified without proper citation, the submission will not be considered for peer review and returned to the authors or immediately rejected.
