Purpose:
To determine the effect of Surgi Wrap (MacroPore Biosurgery, Inc, San Diego, California, USA) in delayed adjustable strabismus surgery.
Design:
An animal study.
Methods:
A prospective, masked-observer, controlled study was performed in rabbits. Forty-eight eyes of 24 rabbits were divided into two groups. After recession of the superior rectus muscle (SRM), Surgi Wrap was applied beneath and over the SRM in the Surgi Wrap group, and no barrier was applied in the control group. Delayed adjustment was performed once on each superior rectus muscle at 1, 2, and 3 weeks after surgery by a masked observer. The possible length to adjust, the force required for the adjustment, and the degree of any adhesions were also evaluated.
Results:
In the control group, adjustment was impossible in all of the five eyes at 1, 2, and 3 postoperative weeks, respectively. In the Surgi Wrap group, adjustment was possible in four of 10 eyes at 1 week after surgery, in two of 10 eyes at 2 weeks after surgery, and in none of the 10 eyes at 3 weeks after surgery.
Conclusion:
The use of Surgi Wrap could delay adjustment in some of the eyes up to 1 or 2 weeks after surgery. Surgi Wrap could be helpful for short-term delayed adjustment in rabbit eyes.
