Abstract
BackgroundTo introduce a new technique of laser-assisted conjunctival cystectomy using pattern scan laser (PASCAL) photocoagulation.Case presentationA 50-years-old Asian woman presented with a conjunctival cyst in the left eye. Slit-lamp examination revealed a 5 mm × 2 mm sized freely movable conjunctival cyst. After a 1 mm × 1 mm sized conjunctival opening was made using PASCAL photocoagulation, the cyst was extracted using a non-toothed forceps without rupture. Two weeks later, complete re-epithelialization of the conjunctiva was observed without any complications. No evidence of recurrence was noted over the 6-month follow-up period.ConclusionConjunctival cystectomy with the adjunctive use of PASCAL photocoagulation can be an effective and safe treatment method.

Summary
To introduce a new technique of laser-assisted conjunctival cystectomy using pattern scan laser (PASCAL) photocoagulation. Simple aspiration is often attempted as the first-line treatment [3], but recurrence occurs frequently because the epithelial cells lining the cyst capsule are not removed [1, 3]. For complete removal of the cyst and prevention of recurrence, various methods have been developed, such as simple resection [1]; surgical excision with visualization of the cyst capsule using tissue dyes, including indocyanine green or trypan blue dye [1, 4]; thermal cautery [5]; intracyst injection of sclerosing agent [6]; cyst rupture using yttrium aluminum garnet (YAG) laser [7]; argon laser photoablation [3]; and highfrequency radio-wave electrosurgery [2].
