My husband is 72 and only once before had the eyelash go inward. Perhaps more from rubbing the eye but we really don't know. What I do know is that washing the eyes with the baby shampoo in the shower seems to help. He also puts Erythromycin ointment on his eye lids at night and Tobramycin drops in 3 times a day for one month. I think the drops are to make sue the eyelash removal area doesn't get infected. All of these things are helping to make his eyes less sensitive to light. He used to wear dark sunglasses indoors now he doesn't.
