To determine the visual outcome and safety of cataract surgery alone and compare with the long-term visual outcome of triple procedure in one-eyed patients.
Retrospective study.
This study reviewed 44 one-eyed patients with cataract coexistent with corneal opacity. The patients who underwent cataract surgery alone (group A, n = 25) were compared with patients managed by triple procedure (group B, n = 19). Outcome measures were the improvement of best corrected visual acuity (BCVA) and period of maintained ambulatory vision. Institutional ethics committee approval was obtained.
The most common etiology of corneal opacity was fungal and the commonest cause of permanent visual loss in other eye was phthisis bulbi. Mean age was 61.2 ± 8.1 years and 62.5 ± 6.9 years in groups A and B, respectively. At each follow-up, the mean postoperative BCVA was found significantly better than the preoperative vision in both groups and at the end of 3 years, mean postoperative vision of group A was better than that of group B (P = 0.012). Group A had longer (33.36 ± 11.97 months) mean period of maintained ambulatory vision than that of group B (26.5 ± 13.5 months) (P = 0.245) and showed less risk of losing ambulatory vision. Limited visual outcome was due to continuing presence of corneal opacity in group A, and graft infection and graft rejection in group B.
Cataract surgery with intraocular lens (IOL) implantation alone can be considered as an alternative or temporary option to provide stable ambulatory vision in one-eyed patients.
评估单眼白内障患者行白内障手术与三联手术的视力预后和安全性,并比较两种术式长期的视力预后。
回顾性研究。
本研究回顾了 44 例合并角膜混浊的单眼白内障患者的临床资料。白内障手术组(A 组,n=25)与三联手术组(B 组,n=19)患者的最佳矫正视力(BCVA)改善情况和可维持日常活动视力的时间作为观察指标。本研究获得了机构伦理委员会的批准。
角膜混浊的最常见病因是真菌,另一眼视力丧失的最常见原因是眼球萎缩。A 组和 B 组患者的平均年龄分别为 61.2±8.1 岁和 62.5±6.9 岁。在每次随访中,两组患者术后的平均 BCVA 均明显优于术前,且在 3 年结束时,A 组的术后平均视力优于 B 组(P=0.012)。A 组可维持日常活动视力的平均时间(33.36±11.97 个月)长于 B 组(26.5±13.5 个月)(P=0.245),且丧失日常活动视力的风险较低。A 组的视力预后较差,是由于角膜混浊持续存在,B 组的视力预后较差,是由于移植物感染和移植物排斥。
对于单眼白内障患者,白内障超声乳化吸除联合人工晶状体(IOL)植入术可作为提供稳定日常活动视力的替代或临时选择。
