Purpose

To compare the impact of routine 7 - 0 Vicryl suturing versus external bipolar diathermy for 23-gauge sclerotomy closure on postoperative ocular-surface integrity and patient discomfort.

Methods

Were randomized to sclerotomy closure with a single 7 - 0 polyglactin (Vicryl) suture at each port or to external bipolar diathermy sealing.

n = 26

Results

tear film stayed intact longer with diathermy - better eye-surface healing

Diathermy NIBUT

7.5s

Vicryl NIBUT

5s

More results

Both groups showed an early postoperative reduction in NIBUT and increased redness, but diathermy demonstrated faster recovery.

No persistent postoperative hypotony occurred.

Conclusion

In primary 23-gauge pars plana vitrectomy with routine port closure, external bipolar diathermy was associated with superior ocular-surface recovery and lower discomfort compared with 7 - 0 Vicryl suturing through 3 months, with reassuring short-term IOP outcomes.
