Purpose: To evaluate the efficacy and safety of conjunctival cystectomy using high-frequency radiowave electrosurgery.

Methods: This retrospective study included 11 patients who underwent conjunctival cystectomy using high-frequency radiowave electrosurgery and had a follow-up of at least 6 months. Briefly, conjunctival opening with a diameter of 1 mm was made with using high-frequency radiowave electrosurgery (Ellman Surgitron; Ellman International, Inc., Hewlett, NY) in cut mode. The cyst was then extracted using a nontoothed forceps through the opening without rupture. Medical record of the patients was reviewed.

Results: In all the 11 patients, conjunctival wound healed in 1 week without any complication. No recurrence was detected in any patients over the 6-month follow-up.

Conclusions: Conjunctival cystectomy with the adjunctive use of high-frequency radiowave electrosurgery was shown to be effective and safe.
