To explore the features of the dominant and nondominant eyes in patients with cataracts and predict ocular dominance shift (ODS) based on preoperative indicators.

Prospective, observational study.
Patients with age-related cataracts who underwent unilateral cataract surgery were enrolled in this study. Before the procedure, uncorrected distance visual acuity (UDVA) was assessed and noncycloplegic subjective refraction evaluations were conducted to determine corrected distance visual acuity. Total astigmatism, corneal astigmatism, and intraocular astigmatism were measured using OPD-Scan III. Cataract type was assessed using slitlamp biomicroscopy based on the Lens Opacities Classification System III. Ocular dominance (OD) was determined under corrected conditions using the hole-in-card test. Follow-up visits occurred at 1 day, 1 week, and 1 month postoperatively. After 1 month, OD was re-evaluated, and participants completed the 9-item Short-Form Cataract Questionnaire.
94 patients (188 eyes) were enrolled in the study. The analysis showed that the ODS rate of unilateral cataract surgery was 40.4%. In addition, age, UDVA of the nondominant eye, posterior subcapsular cataract, and total astigmatism were risk factors for ODS. No difference in vision-related quality of life was detected between patients who had ODS and those who did not.
Several preoperative parameters as potential risk factors of ODS after cataract surgery were identified. These findings provide guidance for predicting changes in the dominant eye and may improve the precise selection of intraocular lenses and implementation of monovision strategies.

前瞻性、观察性研究。
本研究纳入了接受单侧白内障手术的年龄相关性白内障患者。在手术前，评估未矫正远视力（UDVA）并进行非睫状肌主观屈光评估，以确定矫正远视力。使用 OPD-Scan III 测量总散光、角膜散光和眼内散光。根据 Lens Opacities Classification System III ，使用裂隙灯生物显微镜评估白内障类型。在矫正条件下使用孔板测试确定眼优势（OD）。术后 1 天、1 周和 1 个月进行随访。1 个月后重新评估 OD，参与者完成 9 项短式白内障问卷。
本研究纳入了 94 名患者（188 只眼）。分析显示，单侧白内障手术后 ODS 发生率为 40.4%。此外，年龄、非主视眼的 UDVA、后发性白内障和总散光均为 ODS 的危险因素。ODS 患者与未发生 ODS 的患者之间的视力相关生活质量无差异。
确定了几个可能导致白内障手术后 ODS 的术前参数。这些发现为预测主眼变化提供了指导，并可能有助于更精确地选择人工晶状体和实施单视策略。
