Astigmatism shift after extracapsular surgery: Mersilene versus nylon.
International Ophthalmology
|May 1, 1989
Summary
Mersilene and nylon sutures showed no significant difference in wound stability or astigmatism decay over six months. This study compared these two common ophthalmic suture materials in patient wound closure.
Area of Science:
- Ophthalmology
- Biomaterials Science
- Surgical Technology
Background:
- Nylon sutures are commonly used for ophthalmic wound closure.
- Mersilene sutures are suggested to offer superior postoperative wound stability compared to nylon.
Purpose of the Study:
- To compare the postoperative wound stability and astigmatism changes between Mersilene and nylon sutures.
- To evaluate the clinical performance of 11-0 Mersilene versus 10-0 nylon in standard wound closure.
Main Methods:
- A prospective study involving 25 patients undergoing standard wound closure.
- Each patient received bilateral wound closure, with one eye closed using 10-0 nylon and the other using 11-0 Mersilene.
- Astigmatism was monitored over a six-month postoperative period.
Main Results:
- No statistically significant difference was observed in the rate of astigmatism decay between the two suture groups.
- Postoperative wound stability was comparable between eyes closed with Mersilene and nylon sutures.
Conclusions:
- Both Mersilene and nylon sutures provide similar wound stability and astigmatic outcomes in standard ophthalmic wound closure.
- The choice between 11-0 Mersilene and 10-0 nylon may not significantly impact early postoperative astigmatism or wound healing.
