BACKGROUND: Various methods have been used in the treatment of
trichiasis: epilation, excision, cryosurgery, thermocaustic needle,
and argon laser. None of these is satisfactory. Based on the principle
of selective photothermolysis for destroying specifically the
hair follicle, we used a diode laser and evaluated its efficacy.
MATERIAL AND METHODS: Nineteen eyes with 301 itching lashes were
treated in three sessions at intervals of 1 week. In each session
the single hair follicle received laser energy of 20 J/cm2 at
a frequency of 806 nm for 15 ms. We used a bare fiber of 0.8 mm
at a distance of 2 mm from the follicle. RESULTS: After 4 months
two-thirds of the hairs were destroyed. The regrown lashes, however,
are lighter and softer than the original ones. This treatment
is less painful than all others. The laser is small, easy to use,
and inexpensive. CONCLUSIONS: The diode laser is a useful tool
for the treatment of trichiasis. The laser parameters, however,
should be ameliorated.
