Abstract 
 
Purpose:
 

Compare the rate of retinal reattachment and visual acuity resultsamong patients with rhegmatogenous retinal detachment (RRD)who underwent scleral buckle surgery with retinopexy by intraoperativecryotherapy (cryopexy) or postoperative (one month later) laserphotocoagulation (laserpexy)

 
Methods:
 

86 patients with RRD with an indication for scleral buckle surgerywere randomly assigned to cryopexy or laserpexy

 
Results:
 

The rate of 1-week, 1-month and 6-months anatomical successwere similar in the two groups, respectively 93% (40 patients),100% and 100% in the cryopexy group and 95.3% (41 patients),100% and 100% in the laserpexy group. Three patients of cryopexyand 2 of laserpexy needed underwent one additional RRD surgery(pars plan vitrectomy) after primary failure at 1-week follow-up.The rate of postoperative complications were similar in bothgroups, except for eyelid edema. Visual recovery was slowerin the cryotherapy group after one month, but the differencein visual acuity after 6 month postoperative was not significant

 
Conclusions:
 

In patients with uncomplicated retinal detachment, both techniquesof retinopexy have shown a satisfactory anatomical and functionalsuccess. The option of laserpexy offer faster visual acuityrecuperation with less postoperative complications but requiresa second intervention and more cost than cryotherapy
