To evaluate the preoperative clinical and biometric determinants associated with the actual lens position after cataract surgery.
Department of Ophthalmology, University Hospital of Montpellier, France.
Prospective longitudinal cohort study.
The data collected included clinical factors (age, sex, history of vitrectomy) and biometry factors (axial length [AL], anterior chamber depth [ACD], lens thickness, white-to-white [WTW] distance) that might affect actual lens position. Each patient had optical low-coherence reflectometry biometry (Lenstar) preoperatively and 1 month postoperatively. The actual lens position was measured as the postoperative position of the center of the intraocular lens (IOL). Patients were stratified into 3 groups by type of IOL: Acrysof SN60WF or SN6AT (Group 1), Tecnis ZCB00 or ZCT (Group 2), and Asphina 409 MV (Group 3).
The study comprised 168 eyes (mean age 73.3 years ± 9.8 [SD]). The mean actual lens position was 4.88 ± 0.29 mm, 5.01 ± 0.29 mm, and 5.05 ± 0.32 mm in Group 1 (n = 67 eyes), Group 2 (n = 52 eyes), and Group 3 (n = 49 eyes), respectively. In the overall population, AL, ACD, anterior segment depth, and WTW distance were correlated with actual lens position (r = 0.48, P < .0001; r = 0.64, P < .001; r = 0.58, P < .0001; r = 0.39, P < .001, respectively).
The AL, ACD, anterior segment depth, and WTW distance correlated with actual lens position after cataract surgery. The integration of these data in IOL formulas could help improve refractive outcomes after the surgery.
评估白内障手术后实际晶状体位置与术前临床和生物测量学的相关性。
法国蒙彼利埃大学医院眼科。
前瞻性纵向队列研究。
收集的资料包括可能影响实际晶状体位置的临床因素（年龄、性别、玻璃体切除术史）和生物测量学因素（眼轴长度[AL]、前房深度[ACD]、晶状体厚度、白到白[WTW]距离）。每位患者术前和术后 1 个月均行光学低相干反射测量仪生物测量（Lenstar）。实际晶状体位置测量为人工晶状体（IOL）中心的术后位置。患者根据 IOL 类型分为 3 组：Acrysof SN60WF 或 SN6AT（第 1 组）、Tecnis ZCB00 或 ZCT（第 2 组）和 Asphina 409 MV（第 3 组）。
研究共纳入 168 只眼（平均年龄 73.3±9.8 岁）。第 1 组（n=67 眼）、第 2 组（n=52 眼）和第 3 组（n=49 眼）的平均实际晶状体位置分别为 4.88±0.29mm、5.01±0.29mm 和 5.05±0.32mm。在总体人群中，AL、ACD、前段深度和 WTW 距离与实际晶状体位置相关（r=0.48，P<0.0001；r=0.64，P<0.001；r=0.58，P<0.0001；r=0.39，P<0.001）。
AL、ACD、前段深度和 WTW 距离与白内障手术后实际晶状体位置相关。在 IOL 公式中整合这些数据有助于改善术后屈光结果。
