This study evaluated the objective changes in the contralateral eye after unilateral cataract surgery.
The study was designed as retrospective observational study. It included 44 patients who underwent unilateral cataract surgery. Collected data were uncorrected and corrected visual acuity, spherical equivalent, intraocular pressure, contrast sensitivity (CS), stereoacuity, and anterior segment optical coherence tomography parameters. Data were collected preoperatively, and 1 week and 1 month postoperatively for each eye.
Following unilateral cataract surgery, the pupil size of the fellow eye decreased from 3.46 mm to 3.17 mm (postoperative week 1, p = 0.003) and 3.08 mm (postoperative month 1, p < 0.001). Anterior chamber depth of the fellow eye increased significantly from 3.16 mm to 3.27 mm (postoperative week 1, p = 0.005) and 3.26 mm (postoperative month 1, p = 0.001). Uncorrected distance visual acuity (UDVA) of the fellow eye improved significantly at postoperative week 1 (p = 0.042) and postoperative month 1 (p = 0.044). Change of UDVA of the fellow eye at postoperative month 1 was significantly correlated with that of the treated eye (p = 0.039).
Anterior chamber structures changed and UDVA improved in the contralateral eye after unilateral cataract surgery in our cohort. Because fellow eyes were positively affected by monocular cataract surgery, it would be good information if planning for unilateral cataract surgery due to inevitable reasons.
本研究评估了单侧白内障手术后对侧眼的客观变化。
本研究设计为回顾性观察研究。纳入了44例行单侧白内障手术的患者。收集的数据包括未矫正和矫正视力、等效球镜度、眼压、对比敏感度（CS）、立体视锐度和眼前节光学相干断层扫描参数。每只眼睛在术前、术后1周和术后1个月收集数据。
单侧白内障手术后，对侧眼的瞳孔大小从3.46 mm降至3.17 mm（术后第1周，p = 0.003）和3.08 mm（术后第1个月，p < 0.001）。对侧眼的前房深度从3.16 mm显著增加至3.27 mm（术后第1周，p = 0.005）和3.26 mm（术后第1个月，p = 0.00）。对侧眼的未矫正远视力（UDVA）在术后第1周（p = 0.042）和术后第1个月（p = 0.044）显著改善。对侧眼术后第1个月的UDVA变化与患眼的变化显著相关（p = 0.039）。
在我们的队列中单侧白内障手术后对侧眼前房结构发生改变，UDVA改善。由于对侧眼受到单眼白内障手术的积极影响，对于因不可避免的原因而计划进行单侧白内障手术的情况而言，这将是一个有用信息
