目的 :分析老年性白内障患者人工晶体植入术后低视力的原因。方法 :为老年性白内障 15 4例、164眼植入人工晶体 ,观察术后视力恢复状况。结果 :164眼中 ,16例 (9.7% )发生术后低视力 (视力 <0 .3) ,其中 2例 (1.2 % )视力低于 0 .0 5。导致术后低视力的原因有糖尿病视网膜病变 4例 ,角膜斑翳、有青光眼手术史、高度近视各 2例、视神经萎缩、黄斑变性、眼底出血各 1例。手术并发症致低视力 3例。结论 :术后低视力主要与伴有眼病尤其是眼底病变、手术并发症有关 ,因此 ,要重视术前检查 ,以便估计术后情况 ,手术操作要细致 ,以减少并发症的发生。
Objective: To analyze the causes of low vision after artificial lens implantation in senile cataract patients. Methods: 154 cases of senile cataract and 164 cases of artificial lens were implanted. Visual acuity recovery was observed. Results: In 164 eyes, 16 eyes (9.7%) had low visual acuity (visual acuity <0.3), of which 2 eyes (1.2%) had visual acuity less than 0.05. The causes of postoperative low vision were diabetic retinopathy in 4 cases, corneal macula, glaucoma surgery history, 2 cases of high myopia, optic atrophy, macular degeneration and retinal hemorrhage in 1 case. Surgical complications caused by low vision in 3 cases. Conclusions: Postoperative low vision is mainly associated with ocular diseases, especially fundus lesions and complications of surgery. Therefore, we should pay attention to preoperative examination in order to estimate the postoperative condition and the operation operation should be meticulous to reduce the complication.
