AI Article Synopsis
- The study aimed to evaluate the indentation depth and duration of biodegradable PLA96 and silicone sponge implants in a scleral buckling procedure on rabbits.
- Thirty rabbits were divided into two groups, receiving either PLA96 or silicone sponge implants, and were monitored through computed tomography at 1 week, 3 months, and 5 months post-surgery.
- Results showed that the PLA96 implant produced less initial indentation than the silicone sponge, and its indentation decreased over time, with no complications reported for either implant type.
Article Abstract
Purpose: To measure the amount and duration of indentation depth achieved with biodegradable poly-L/D-lactide 96/4 (PLA96) and silicone sponge implants.
Methods: Thirty rabbits underwent a scleral buckling procedure. A PLA96 buckling implant was used in 15 rabbits and a silicone sponge buckling implant was in 15 rabbits. A circumferential scleral buckling implant was sutured episclerally on the left eye of each rabbit, just temporal to the superior rectus muscle and 7 mm posterior to the limbus. Computed tomography was performed at 1 week, 3 months, and 5 months after surgery.
Results: The PLA96 buckling implant (implant diameter, 3-3.5 mm) used in this study created lower indentation than the silicone sponge implant (implant diameter, 4 mm). The indentation created by the PLA96 implant decreased over time compared with that created by the silicone implant. There were no complications related to either kind of implant.
Conclusion: Both the silicone sponge implant and the PLA96 implant caused indentation that decreased in a comparable manner over the follow-up period (5 months).
