Abstract

Purpose: To assess the influence of ocular biometric parameters on intraocular lens (IOL) tilt and decentration after cataract surgery.

Methods: Patients scheduled for cataract surgery were screened for inclusion in this prospective cohort study. Tilt and decentration of the crystalline lens and IOL were measured using the CASIA2 (Tomey). Anterior chamber depth (ACD), lens thickness (LT), and axial length (AL) were preoperatively measured by the IOLMaster 700 (Carl Zeiss Meditec AG). Multivariate regression analysis was performed to assess the influence of ocular biometric parameters on IOL tilt and decentration after cataract surgery.

Results: In total, 191 eyes of 120 patients were included. Age was positively correlated with IOL tilt, whereas ACD and AL were negatively correlated with IOL tilt. A strong positive correlation was found between preoperative crystalline lenses and postoperative IOLs in tilt magnitude (r = 0.769, P < .001) and tilt direction (r = 0.688, P < .001). A positive correlation was found between preoperative and postoperative lens decentration magnitude and decentration direction. Greater postoperative IOL tilt and decentration were significantly associated with greater preoperative crystalline lens tilt (P < .001) and decentration (P = .027).

Conclusions: IOL tilt was greater in older patients. Shorter AL and shallower ACD contributed to greater IOL tilt. The tilt and decentration of the IOL will be greater in patients with greater tilt and decentration of the crystalline lens. [J Refract Surg. 2024;40(7):e438-e444.].

眼部生物测量参数对眼内透镜位置的影响：前瞻性队列研究

目的：评估眼部生物测量参数对白内障手术后人工晶体（IOL）倾斜和分散的影响：方法：筛选计划接受白内障手术的患者，将其纳入这项前瞻性队列研究。使用 CASIA2（Tomey）测量晶状体和人工晶体的倾斜度和偏斜度。前房深度（ACD）、晶状体厚度（LT）和轴向长度（AL）在术前由 IOLMaster 700（卡尔蔡司医疗股份公司）测量。进行了多变量回归分析，以评估眼部生物测量参数对白内障手术后人工晶体倾斜和分散的影响：结果：共纳入了 120 名患者的 191 只眼睛。年龄与人工晶体倾斜度呈正相关，而 ACD 和 AL 与人工晶体倾斜度呈负相关。术前晶体镜片与术后人工晶体在倾斜幅度（r = 0.769，P < .001）和倾斜方向（r = 0.688，P < .001）方面存在很强的正相关性。术前和术后人工晶体的分散幅度和分散方向呈正相关。术后人工晶体倾斜度和分散度增大与术前晶体倾斜度增大（P < .001）和分散度增大（P = .027）显著相关：结论：老年患者的人工晶体倾斜度更大。结论：年龄较大的患者人工晶体倾斜度较大，较短的AL和较浅的ACD导致人工晶体倾斜度较大。晶状体倾斜和分散程度越大的患者，人工晶体的倾斜和分散程度也越大。[J Refract Surg. 2024;40（7）：e438-e444]。

期刊介绍： The Journal of Refractive Surgery, the official journal of the International Society of Refractive Surgery, a partner of the American Academy of Ophthalmology, has been a monthly peer-reviewed forum for original research, review, and evaluation of refractive and lens-based surgical procedures for more than 30 years. Practical, clinically valuable articles provide readers with the most up-to-date information regarding advances in the field of refractive surgery. Begin to explore the Journal and all of its great benefits such as: • Columns including “Translational Science,” “Surgical Techniques,” and “Biomechanics” • Supplemental videos and materials available for many articles • Access to current articles, as well as several years of archived content • Articles posted online just 2 months after acceptance.
