Phacoemulsification has proven to be a breakthrough technique in cataract surgery. Its popularity has grown dramatically as procedures and equipment have advanced, improving both safety and efficiency. This study presents long-term outcomes from phacoemulsification surgeries performed at the Evangelical Church Winning All (ECWA) Eye Hospital, a tertiary eye care center.
This prospective clinical cohort study followed standard practices for operations performed under local anesthesia. Ophthalmologists evaluated long-term outcomes and predictors of improved visual acuity after phacoemulsification cataract surgery. The visual recovery of the patients over time was evaluated, and the factors that influence the gains in vision were identified.
A total of 177 patients were subjected to treatment at our facilities during the study period. There were 116 male and 61 female patients, which resulted to a male-to-female ratio of 1 : 0.53. The average age of the patients was 59.18 years with a standard deviation of 11.38 years. Of the 259 eyes treated, 249 eyes (96.1%) achieved a high success rate with visual acuity of 6/6 - 6/18. Ten (10) eyes (3.9%) had moderate acuity between <6/18 and 6/60. Follow-up examinations over five years after phacoemulsification showed poor vision outcomes among old patients. The primary factor that affected improvement in visual acuity among patients was amblyopia, present in 30% of cases. Posterior capsular opacification and macular edema collectively accounted for 20% of poor vision cases, while optic atrophy, glaucoma, and retinal hemorrhage each represented approximately 10% of poor vision cases.
The phacoemulsification approach demonstrated a highly effective restoration of vision for the vast majority, while long-term data analysis indicated the potential for age-related variability in postoperative visual gains.
超声乳化术已被证明是白内障手术中的一项突破性技术。随着手术操作和设备的进步，其安全性和效率都得到了提高，因此该技术的普及程度大幅增长。本研究展示了在三级眼科护理中心福音教会全胜（ECWA）眼科医院进行的超声乳化手术的长期结果。
这项前瞻性临床队列研究遵循了局部麻醉下手术的标准操作规范。眼科医生评估了超声乳化白内障手术后的长期结果以及视力改善的预测因素。评估了患者随时间的视力恢复情况，并确定了影响视力提高的因素。
在研究期间，共有177名患者在我们的机构接受了治疗。其中男性患者116名，女性患者61名，男女比例为1∶0.53。患者的平均年龄为59.18岁，标准差为11.38岁。在接受治疗的259只眼中，249只眼（96.1%）获得了高成功率，视力达到6/6 - 6/18。10只眼（3.9%）的视力中等，在<6/18至6/60之间。超声乳化术后五年的随访检查显示，老年患者的视力结果较差。影响患者视力改善的主要因素是弱视，占病例的30%。后囊膜混浊和黄斑水肿共同占视力不佳病例的20%，而视神经萎缩、青光眼和视网膜出血各约占视力不佳病例的10%。
超声乳化术对绝大多数患者显示出了非常有效的视力恢复效果，而长期数据分析表明术后视力改善可能存在与年龄相关的差异。
