Trichiasis is the medical name for a condition characterized by misdirected or abnormally positioned eyelashes. These eyelashes typically direct inward and brushes against the eye. It can cause discomfort and irritation to the eye and lead to permanent damage to the cornea and vision loss. Symptoms of trichiasis include:
•Constant eye irritation
•Eye pain, redness and/or irritation
•Excessive tearing
•Excessive sensitivity to light

Treatment for trichiasis depends on the number of eyelashes affecting the surface of the eye. For temporary relief, the eyelashes can be plucked with a forcep in the office, but they generally grow back. For more severe cases and for recurrent diseases, permanent removal of the affected eyelash follicles using a special radiofrequency device is recommended. If the trichiasis is also associated with entropion, corrective eyelid surgery may be necessary.
