目的 :探讨白内障超声乳化及人工晶状体植入术后人工晶状体异位的相关因素及手术治疗。方法 :对人工晶状体偏位者 11只眼 ,瞳孔夹持者 13只眼 ,袢脱入前房者 3只眼 ,共 2 7只眼行人工晶状体复位术 ,2 6只眼行单纯复位术 ,1只眼行缝线固定复位术。观察其视力的变化 ,并回顾分析其病史、白内障手术的情况、人工晶状体的类型以及异位情况 ,以了解引起异位的相关因素。结果 :(1)病史 :老年性白内障 9只眼 ,非老年性白内障 18只眼 (外伤性白内障 8只眼、先天性白内障 5只眼、混合性白内障 4只眼、Marfan综合征 1只眼。合并青光眼者 4只眼、高度近视 3只眼、外伤性瞳孔裂伤 2只眼、糖尿病 1只眼 )。 (2 ) 13只眼白内障手术中 :开罐式撕囊 1只眼 ;撕囊口偏大者 (7～ 8mm) 2只眼 ,略偏中心 1只眼 ;玻璃体溢出 1只眼 ;瞳孔散大 (6～ 7mm)、变形 6只眼 ;植入的人工晶状体为C袢 ,夹角为 5～ 10°。 (3)人工晶状体复位术前裸眼远视力为 0 2 0±0 19,术后为 0 36± 0 2 4 (P <0 .0 0 1)。术后视力提高者 15只眼 ,不变者 11只眼 ,下降者 1只眼。结论 :人工晶状体异位的相关因素包括患者的病情、手术技巧及术后处理。关键要早期发现 ,早期治疗。人工晶状体复位术是一有效的方法。
Objective: To investigate the related factors and surgical treatment of phacoemulsification after phacoemulsification and intraocular lens implantation. Methods: 11 eyes of IOL, 13 eyes of pupil holder, 3 eyes of 袢 anterior chamber were removed, 27 eyes were treated with IOL reduction, 26 eyes were treated with simple reduction, One eye suture fixation reset. Observe the changes of visual acuity, and review its history, cataract surgery, intraocular lens and ectopic situation, to understand the etiology of etiology related factors. Results: (1) Medical history: 9 eyes of senile cataract, 18 eyes of non-senile cataract (traumatic cataract 8 eyes, congenital cataract 5 eyes, mixed cataract 4 eyes and Marfan syndrome 1 eye). 4 eyes with glaucoma, 3 eyes with high myopia, 2 eyes with traumatic pupil laceration, 1 eye with diabetes). (2) During the operation of 13 cataractous eyes, there were 1 can of open canned capsulorhexis, 2 eyes of large capsulorhexis (7 ~ 8mm), 1 eye slightly eccentric, 1 eye of vitreous overflow, (6 ~ 7mm), deformed 6 eyes; implanted intraocular lens C 袢, the angle of 5 ~ 10 °. (3) The intraocular lens (IOL) distance vision before surgery was 0 2 0 ± 0 19 and 0 36 ± 0 2 4 (P 0 01). 15 eyes improved postoperative visual acuity, unchanged in 11 eyes, decreased in 1 eye. CONCLUSIONS: Factors associated with IOLs include the patient’s condition, surgical technique, and postoperative management. The key to early detection, early treatment. IOL reduction is an effective method.
