Abstract: Introducing a new technique to remove the conjunctival cyst using atmospheric
low-temperature plasma (ALTP) and assessing its effectiveness.
Methods: Five eyes with conjunctival cysts were included in this study. The
procedure was started by applying a plasma spot on the highest point of the cyst, and then
other spots were spirally applied to the base of the cyst to debulk it. The conjunctival cysts
were removed using the white handpiece of the plasma generator device (Plexr, GMV s.r.l
Grottaferrata, Italy). Refraction, visual acuity, intraocular pressure (IOP), contrast sensitivity
(CS), aberrometry, dry eye tests, and ocular surface disease index (OSDI) questionnaire were
measured before, one and six months after treatment.
Results: The mean size of the cysts was 3.6 mm (range 2.1 to 4.8 mm). No intraoperative
and postoperative complications were observed. Postoperative examinations showed that the
patients’ cysts were completely healed and recurrence did not occur. Significant changes in
visual parameters, IOP, CS, aberrometry and dry eye tests were not observed in the follow-up
periods after treatment compared to before. OSDI score decreased after cyst removal.
Conclusion: Our recommended technique using ALTP can be used as a new approach to
treating conjunctival cysts. This technique is a simple, office-based, minimally invasive,
effective and inexpensive way to remove a cyst
