Summary
Suture erosion after penetrating keratoplasty is linked to longer time post-surgery, superior suture location, topical steroid use, and inflammatory conditions. These factors increase risks like infection and graft rejection.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Ocular Surface Disease
Background:
- Suture erosion following keratoplasty is a significant risk factor for complications.
- Complications include inflammation, infection, neovascularization, and graft rejection.
- Identifying associated patient characteristics is crucial for preventative strategies.
Purpose of the Study:
- To identify patient characteristics associated with 10-0 nylon suture erosion after keratoplasty.
- To analyze factors contributing to suture erosion and its timing post-surgery.
Main Methods:
- Retrospective study of 100 eyes from 97 patients with suture erosion post-keratoplasty.
- Data collected included patient age, diagnosis, time from surgery, suture characteristics, and treatment history.
- Analysis of suture location, integrity, topical steroid use, and presence of infiltrate.
Main Results:
- Average time to presentation was 33 months post-keratoplasty.
- Superior suture location was most common (53%).
- Erosion occurred earlier with topical steroid use (29 months) and for inflammatory conditions (p=0.09).
Conclusions:
- Increased time since surgery, superior suture placement, topical steroid use, and pre-existing inflammatory ocular conditions are associated with suture erosion.
- These findings aid in managing patients at risk for suture erosion after penetrating keratoplasty.
