Abstract

Purpose: To investigate the relationship between intraocular pressure (IOP) and axial length (AL) and to compare the refractive predicted error in patients who have undergone cataract surgery alone or in combination with trabeculotomy.

Setting: Hospital.

Design: Single-center, retrospective, case-control.

Methods: The medical records of patients who had undergone cataract surgery alone or in combination with trabeculotomy using the Tanito microhook were retrospectively reviewed. Patients were grouped into cataract surgery alone (CAT) or cataract surgery combined with trabeculotomy (LOT) groups. Demographic data, preoperative and postoperative IOP and AL, and surgically induced astigmatism (SIA) were analyzed before and 1 month postoperatively to evaluate the interplay between IOP, AL, and refractive outcomes.

Results: 52 eyes (52 patients) underwent LOT, and 67 eyes (67 patients) underwent CAT. The mean IOP at baseline did not differ between the groups; the change in IOP (dIOP) was significantly higher in the LOT group than in the CAT group. The mean AL at baseline and the change in AL (dAL) were 24.0 ± 1.2 mm and 0.16 ± 0.11 mm, respectively, in the LOT group, and 23.8 ± 1.1 mm and 0.11 ± 0.070 mm, respectively, in the CAT group. The difference in dAL was also significant. In the LOT group, dIOP and dAL were significantly correlated. The mean SIA vectors did not significantly differ between the groups.

Conclusions: AL decreased because of the reduction in IOP after cataract surgery combined with trabeculotomy. Consequently, the refractive target error was greater, and the postoperative refractive outcome showed a tendency toward hyperopia.

小梁切开术后眼压降低对轴长和眼内透镜选择的影响

目的：研究眼内压（IOP）和轴向长度（AL）之间的关系，并比较单独接受白内障手术或结合小梁切开术的患者的屈光预测误差：医院：设计：单中心、回顾性、病例对照：方法：回顾性审查使用谷藤微钩单独或联合小梁切开术进行白内障手术的患者的病历。患者被分为单纯白内障手术组（CAT）和白内障手术联合小梁切开术组（LOT）。对患者的人口统计学数据、术前和术后眼压（IOP）和角膜屈光度（AL）以及手术引起的散光（SIA）进行了分析，以评估眼压（IOP）、角膜屈光度（AL）和屈光结果之间的相互作用v：52只眼睛（52名患者）接受了LOT手术，67只眼睛（67名患者）接受了CAT手术。两组基线时的平均眼压没有差异；LOT 组的眼压变化（dIOP）明显高于 CAT 组。LOT 组基线平均 AL 值和 AL 值变化（dAL）分别为 24.0±1.2 mm 和 0.16±0.11 mm，CAT 组分别为 23.8±1.1 mm 和 0.11±0.070 mm。dAL 的差异也很显著。在 LOT 组，dIOP 和 dAL 显著相关。各组的平均 SIA 向量没有明显差异：结论：白内障手术联合小梁切开术后，由于眼压降低，AL也随之降低。结论：白内障手术联合小梁切开术后，由于眼压降低，AL下降，因此屈光目标误差增大，术后屈光结果显示出远视趋势。
