目的评价分析老年性白内障术后视力恢复不良的原因。方法对1154眼老年性白内障摘除及人工晶状体植入术后l～3个月随访检查视力及眼前、后段情况,分析其脱盲率、脱残率和未脱残原因。结果本组病例,脱盲率(矫正视力≥0.05)为96.62%,脱残率(矫正视力≥0.3)88.56%。未脱残(矫正视力<0.3)共132眼,其中因合并眼部其它病变(高度近视黄斑病变、糖尿病视网膜病变、视神经萎缩等)99眼占75%;因手术操作有关所致井发症(后囊破裂,玻璃体脱出、葡萄膜炎、人工晶状体移位等)32眼占25%。结论老年性白内障术后低视力的主要原因是同时合并眼部其它病变,其次是手术严重并发症。不断提高白内障手术的技术水平减少并发症是提高脱残率的重要措施,但是对老年性白内障合并视神经、视网膜多种病变者,术后视力恢复不良应有充分估计,尽管术后可能影响脱残率,但仍应积极手术,尽可能提高患者视力。
Objective To evaluate the causes of poor visual acuity after senile cataract surgery. Methods 1154 eyes with senile cataract extraction and intraocular lens implantation were followed up from 1 to 3 months to examine the visual acuity and the anterior and posterior segments. The causes of blindness rate, disability rate and non-disability were analyzed. Results In this group of patients, the blindness rate (corrected visual acuity≥0.05) was 96.62%, and the disability rate (corrected visual acuity ≥0.3) 88.56%. A total of 132 eyes had no dislocation (corrected visual acuity <0.3), of which 99 eyes (75%) had other ophthalmological lesions (macular myopia, diabetic retinopathy, optic atrophy, etc.) Posterior capsule rupture, vitreous prolapse, uveitis, intraocular lens shift, etc.) accounted for 25% of 32 eyes. Conclusions The main reason for postoperative low vision after senile cataract surgery is the combination of other eye diseases. The second is the serious complications of surgery. Continued to improve the technical level of cataract surgery to reduce complications is an important measure to improve the disability rate, but for senile cataract with optic nerve, multiple retinal lesions, poor postoperative visual acuity should be fully estimated, although postoperative may affect the disabled Rate, but still should be actively surgery, as much as possible to improve patient vision.
