To evaluate circular neodymium: YAG laser incision in cases of anterior capsular contraction syndrome (ACCS) by comparing it to radial Neodymium: YAG laser incision as for efficacy and safety.
Ophthalmology Department, Benha University Hospitals.
The study was done on 74 eyes of 66 patients with symptomatic ACCS. Eyes were randomly allocated to one of the two groups. Group I were treated by circular YAG laser anterior capsulotomy. Group II were treated by radial YAG laser anterior capsulotomy. All cases passed a full ophthalmic examination before laser capsulotomy, 1 week, 1 month, 6 months and 12 months after laser.
BCVA at the 1st week and the 1st month after the capsulotomy did not show any significant difference between the two groups; however at the 3rd and 6th months, the circular group showed better visual acuity than the radial group (p 0.001 and < 0.001, respectively). All post-YAG UCVA and BCVA were significantly higher than pre-YAG UCVA and BCVA in both groups. IOL decentration occurred in two cases in radial group. Circular group had significantly higher percentage of contraction relief (94.4%) than the radial group (66.7%) with p value 0.003.
Circular Nd:YAG anterior capsulotomy is more effective and safe than radial capsulotomy in 1-year follow-up.
通过将环形钕：钇铝石榴石激光切开术与放射状钕：钇铝石榴石激光切开术的疗效和安全性进行比较，评估其在前囊收缩综合征（ACCS）病例中的应用。
本哈大学医院眼科。
对66例有症状的ACCS患者的74只眼睛进行研究。将眼睛随机分为两组。第一组采用环形钇铝石榴石激光前囊切开术治疗。第二组采用放射状钇铝石榴石激光前囊切开术治疗。所有病例在激光前囊切开术前、术后1周、1个月、6个月和12个月均进行了全面的眼科检查。
两组在囊切开术后第1周和第1个月时的最佳矫正视力（BCVA）无显著差异；然而，在第3个月和第6个月时，环形组的视力优于放射状组（分别为p<0.001和p<0.001）。两组术后的矫正视力（UCVA）和最佳矫正视力均显著高于术前。放射状组有2例发生人工晶状体偏心。环形组的收缩缓解率（94.4%）显著高于放射状组（66.7%），p值为0.003。
在1年的随访中，环形钕：钇铝石榴石前囊切开术比放射状前囊切开术更有效且更安全。
