Cataract surgery is a commonly performed procedure aimed at restoring vision in individuals affected by cataracts. The duration of recovery following cataract surgery can vary among patients and is influenced by a multitude of factors. Therefore, the purpose of this study was to determine the time to recovery from cataracts and its predictors among patients treated with cataract surgery at two selected Public Hospitals in Hawassa, Sidama regional state, Ethiopia.
Institution-based retrospective cohort study was conducted among 444 cataract patients treated with surgery from January 01, 2019, to December 30, 2021. A simple random sampling method was used to select two public hospitals. The data was collected using Kobo toolbox Version 4 and trained data collectors. STATA Version 16 was used for analysis. To estimate the recovery time and compare survival probability among variables Kaplan-Meir curve and Log-rank test were used. The cox-Proportional hazards model was used to identify significant predictors of time to recovery. The association was reported using the adjusted hazards ratio (AHR) with a 95% confidence interval (95%CI), and the significance level was set at a p-value of 0.05.
This study showed that 76.14% of cataract patients recovered from cataracts. The average time taken to recover from a cataract was 30 weeks (IQR = 15 to 48) 95%, CI, (26-33). Age 40-60 years (AHR = 2.04 CI; 1.12-3.82), urban dwellers (AHR = 1.48; 95% CI, 1.13-1.93), medium/high level of visual acuity (AHR = 1.49 CI; 1.14-1.94), secondary cataract (AHR = 1.56 CI; 1.11-2.18) and traumatic cataract (AHR = 1.82 CI; 1.32-2.52) were associated with time to recovery of cataract patients.
According to this study, the time to recovery of cataract patients was slightly high. Cataract patients' time to recovery was affected by age, residence, pre-operative visual acuity, presence of diabetes mellitus, and post-operative complications. To improve recovery time of cataract patients, treatment strategies must be prioritized.
白内障手术是一种常见的手术，旨在恢复白内障患者的视力。白内障手术后的恢复时间因患者而异，受多种因素影响。因此，本研究旨在确定在埃塞俄比亚西达玛地区哈瓦萨的两家选定公立医院接受白内障手术治疗的患者从白内障中恢复的时间及其预测因素。
这是一项基于机构的回顾性队列研究，研究对象为 2019 年 1 月 1 日至 2021 年 12 月 30 日期间接受手术治疗的 444 名白内障患者。采用简单随机抽样方法选择两家公立医院。数据使用 Kobo 工具包版本 4 和经过培训的数据收集器收集。使用 STATA 版本 16 进行分析。为了估计恢复时间并比较变量之间的生存概率，使用 Kaplan-Meier 曲线和对数秩检验。使用 Cox 比例风险模型确定恢复时间的显著预测因素。使用调整后的风险比 (AHR) 及其 95%置信区间 (95%CI) 报告相关性，并将显著性水平设置为 p 值为 0.05。
本研究表明，76.14%的白内障患者从白内障中恢复。从白内障中恢复的平均时间为 30 周（IQR = 15 至 48）95%CI，（26-33）。40-60 岁年龄组（AHR = 2.04 CI；1.12-3.82）、城市居民（AHR = 1.48；95%CI，1.13-1.93）、中/高度视力（AHR = 1.49 CI；1.14-1.94）、继发性白内障（AHR = 1.56 CI；1.11-2.18）和外伤性白内障（AHR = 1.82 CI；1.32-2.52）与白内障患者的恢复时间相关。
根据本研究，白内障患者的恢复时间略长。白内障患者的恢复时间受年龄、居住地、术前视力、是否患有糖尿病以及术后并发症的影响。为了缩短白内障患者的恢复时间，必须优先制定治疗策略。
