非正常晶状体眼行人工晶状体悬吊术的疗效观察

观察由各种原因导致的非正常晶状体眼因无足够后囊膜支撑而施行人工晶状体悬吊术的疗效。 方法:使用美国ALCON公司CZ70BD悬吊式人工晶状体对8例9眼非正常晶状体白内障患者（过熟期白内障3眼，外伤性白内障伴晶状体半脱位4眼，马凡氏综合征2眼）因术中无后囊膜支撑施行人工晶状体悬吊术；对8例8眼Ⅰ期白内障术后非正常晶状体眼患者（伴有瞳孔异常的无晶状体眼7眼，人工晶状体严重偏位1眼）施行Ⅱ期人工晶状体悬吊术,观察其术中、术后并发症及术后视力情况。随访1~6mo。 结果:术中或术后5眼（29%）出现前房或玻璃体少量出血，10d左右基本吸收；术后1眼（6%）发生脉络膜脱离，1mo恢复；切口微漏致低眼压2眼（12%），加压包扎5d恢复。术后1d，裸眼视力＞0.1者13眼（76%）；术后10d，裸眼视力＞0.1者17眼（100%），术后10，30d，裸眼视力＞0.3者分别为11眼（65%）和12眼（71%）。 结论:人工晶状体悬吊术是治疗易发生无后囊膜支撑的非正常晶状体眼的一种较好的选择。

Therapeutic effect of suture-fixation of intraocular lens for non-normal lens eye

AIM:To observe the clinical therapeutic effect of suture-fixation of intraocular lens(IOL) for non-normal lens eye of non-posterior capsule because of all kinds of reasons.METHODS:Alcon CZ70BD IOL was selected.8 cases(9 eyes) of non-normal lens(including 3 eyes of hypermature cataract,4 eyes of traumatic cataract with subluxation,2 eyes of Marfan’s syndrome) were treated with suture-fixation of IOL because of non-posterior capsule or disintegrated-posterior capsule;8 cases(8 eyes) of non-normal lens that had been treated with cataract surgery(including 7 aphakic eyes with pupillary complications,1 eye of dislocated IOL) were treated with secondary suture-fixation of IOL.Main outcome measures were visual acuity and complications.All the patients were followedup for 1-6 months.RESULTS:Mild anterior chamber or vitreous hemorrhage occurred in 5 eyes(29%) intraoperatively or postoperatively and cured in 10 days.Choroidal detachment was observed in 1 eye(6%) and cured in 1 month.Ocular hypotension because of mild incision leakage occurred in 2 eyes(12%) postoperatively and cured by hypertension bandaging in 5 days.Uncorrected visual acuity >0.1 was achieved in 13 eyes(76%) at the first day and 17 eyes(100%) at the 10th day;Uncorrected visual acuity >0.3 was achieved in 11 eyes(65%) and 12 eyes(71%) at the 10th day and 1st month.CONCLUSION:Suture-fixation of IOL is a good choice for non-normal lens eye of non-posterior capsule.
