This randomized controlled trial evaluated the effectiveness of a modified soft contact lens (MSCL) in maintaining visual clarity and protecting the cornea during vitrectomy. Patients were assigned to either an MSCL group or a balanced salt solution (BSS) group. The MSCL group demonstrated significantly better intraoperative visual clarity and corneal hydration compared to the BSS group (P < .05).
Key findings
- The MSCL group had significantly better intraoperative visual clarity than the BSS group (P < .05).
- Corneal edema and fluorescein staining were significantly improved in the MSCL group at 1 day and 1 week (P < .05).
- Surgical time and vitrectomy duration were comparable between the MSCL and BSS groups (P > .05).
- Ocular Surface Disease Index scores did not differ significantly between groups.
Why it matters
Maintaining intraoperative visual clarity and protecting the cornea are critical during vitrectomy. The use of MSCL may enhance surgical outcomes and patient comfort without increasing surgical time.
