PURPOSE: In this prospective study, argon laser photocoagulation
was used to eliminate misdirected cilia. The cases were followed
up to see the results and recurrences with this treatment. METHODS:
60 eyelids of 45 patients with trichiasis were treated with the
argon laser. After topical anesthesia a blue-green argon laser
was used with 1 watt power, for 0.20 seconds, with 100 micrometer
beam diameter. The beam was directed coaxially to the lash follicle
to create a 2-3 mm crater and vaporization was observed. After
crater formation, the laser parameters were changed to 1.2 watt
power, for 0.20 seconds, with 200 micrometer beam diameter, to
destroy residual follicular tissue. Up to five lashes were treated
in one session. At the end of each session an antibiotic ointment
was used t.i.d. for a week. RESULTS: Patients have been followed
for 4-12 months (mean 6 months). Recurrences have been seen in
15 of 60 eyelids (25%). Laser treatment has been used with the
same protocol for the cases with recurrence and results have been
successful in eight of them. Postoperatively severe pain, hemorrhage,
scar formation, neovascularization of lid margin, or infection
were not seen in any patient. In three cases mild hypopigmentation
and in three other cases mild lid notching were observed. CONCLUSIONS:
Argon laser lash ablation can be done as an effective office procedure
with topical anesthesia. The advantages include low recurrence
and complication rates in carefully selected patients and minimal
postoperative discomfort.
