Abstract Details


To compare a new technique of YAG laser capsulotomy (circular capsulotomy with an inferior hinge) with commonly practiced circular YAG laser capsulotomy for management of posterior capsular opacification.


The study was performed in Farabi Eye Hospital, Tehran University of Medical sciences, Tehran, Iran.


The study was Prospective Randomized Clinical Trial. Pseudophakic patients with visually significant posterior capsule opacification entered into the study and divided randomly into two groups. Patients with history of any ocular trauma or surgery were excluded. In the first group patients underwent routine circular capsulotomy, and patients in the second group underwent capsulotomy with similar technique, with leaving an inferior hinge. Corrected distance visual acuity (CDVA) was measured before and after capsulotomy. After 3-month follow up, they were asked about annoying floater.


From 83 patients, 43 underwent hinged form of posterior YAG capsulotomy and 40 patients underwent routine circular capsulotomy. There was no significant difference between postoperative CDVA of the two groups. After 3 month, there was a significantly higher degree of annoying floater in the circular capsulotomy group (P value=0.02). There was no statically significant difference in total delivered energy (P value=0.4) or number of spots (P value=0.2) between 2 groups.


Hinged capsulotomy seems effective in decreasing floater rate after YAG laser capsulotomy for posterior capsular opacification.
