摘要
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。
Purpose To analyze the causes of low - vision after senile cataract operation in rural areas. Methods 1 154 eyes of senile cataract extraction and intraocular lens implantation after 1 - 3months were reviewed. Vision and the anterior and posterior of eyes were examined.The causes of the rate of de - blindness, de - disability and disability were analyzed. Results In our study,the rate of de - blindness (corrected visual acuity ≥0.05) was 96.62% ,the rate of de - disability (corrected visual acuity ≥0.3) was 88.56% .Disability eyes (corrected visual acuity <0.3) were 132 cases.In the 132 cases, 99 eyes (75%) were caused by other diseases (diabetic retinopathy, optic atrophy, macular degeneration due to high degree of myopia etc. ) ; 33 eyes (25%) were caused by complications in operations (posterior capsule disruption, vitreous extrusion , uveitis, intraocular lens displacement, etc.) . Conclusion The main causes of low vision after senile cataract poeration were cataract in company with other ocular diseases. The other causes were serious operative complications. Improvement of cataract operative skills in order to reduce complications was the main method to improve the rate of de - disability. In senile cataract operation with retinal and optic nerve diseases,bad visual acuity should be estimated. Although there exists the rate of de - disability after operations, patients should be operated on actively and visual acuity might be improved as soon as possible.
