目的了解农村防盲工作短期集中白内障手术质量和存在问题。设计人群为基础的流行病学调查。研究对象251例(254眼)接受白内障手术患者,其中131例(134眼)接受术后调查。方法患者施行白内障小切口非超声乳化现代囊外摘除+人工晶状体植入术,术后6个月时通知患者在手术医院进行复查,检查远视力、近视力、外眼、眼前节、眼后节、眼压。主要指标视力、眼压、屈光度及手术并发症。结果术后6个月时裸眼远视力≥0.3者占41.8%,裸眼远视力≥0.05者占82.8%;矫正远视力≥10.3者占64.2%,矫正远视力≥0.05者占92.3%。裸眼近视力≥0.1者占79.9%,矫正近视力≥0.1者占85.8%。屈光不正、后发障、瞳孔变形、瞳孔移位、人工晶状体色素沉着、人工晶状体偏位、高眼压是主要术后并发症。合并的玻璃体、视网膜和视神经疾病是影响术眼脱盲的主要因素,影响患眼脱残的原因除此以外,还包括屈光不正和后发障等。结论影响手术效果的严重并发症均控制在较低范围内,玻璃体、视网膜和视神经疾病是影响患眼脱盲的主要因素。需增加检查设备以提高防盲手术中人工晶状体屈光度的准确性。
Objective To understand the short-term cataract surgery quality and existing problems in rural anti-blind work. Design population-based epidemiological survey. Subjects 251 patients (254 eyes) received cataract surgery, 131 (134 eyes) underwent postoperative investigation. Methods The patients underwent small incision cataract phacoemulsification using modern extracapsular cataract extraction and intraocular lens implantation. At 6 months after operation, the patients were inspected in the operation hospital for examination. The patients were examined for distance vision, near vision, outer eyes, anterior segment, ,intraocular pressure. The main indicators of vision, intraocular pressure, diopter and surgical complications. Results At 6 months after operation, the uncorrected visual acuity ≥0.3 accounted for 41.8%, the uncorrected visual acuity ≥0.05 accounted for 82.8%, the corrected distant vision ≥10.3 accounted for 64.2%, and the corrected distant vision ≥0.05 accounted for 92.3%. The naked eye near vision ≥ 0.1 accounted for 79.9%, correction of near vision ≥ 0.1 accounted for 85.8%. Refractive error, posterior obstacle, pupil deformation, pupil displacement, intraocular lens hyperplasia, intraocular lens deviation, ocular hypertension is the main postoperative complications. The combined vitreous, retinal and optic nerve diseases are the main factors that affect the surgical blindness, and the reasons that affect the disability of the affected eyes include, among other things, refractive errors and post-cataracts. Conclusions The serious complications that affect the effect of surgery are controlled in a relatively low range. Vitreous, retinal and optic nerve diseases are the main factors affecting the blindness of the eye. Need to increase the inspection equipment to improve the accuracy of intraocular lens refraction during anti-blind surgery.
