Abstract
PurposeTo describe a simple and minimally invasive technique using double-frequency YAG laser for correction of mild medial lower eyelid ectropion with punctal eversion and assess the efficacy of the technique by measuring the tear film meniscus pre- and post-laser treatment using imageJ software.MethodsThis study included 23 eyes of 19 patients with lower eyelid ectropion with punctal eversion. All patients were treated by double-frequency YAG laser applied to lower medial conjunctiva. Tear film thickness was assessed using imageJ software pre- and post-argon laser treatment.ResultsThere was a highly significant change detected after argon laser treatment as regarding the mean of the height of tear film which was found to be significantly lower after argon laser treatment compared to before it (81.1 pixels versus 193.1 pixels, respectively) (P < 0.001).ConclusionDouble-frequency YAG laser applied to lower medial palpebral conjunctiva is a simple, easy, safe, and effective procedure which can be used as a solo treatment in early cases of punctal eversion with no or mild medial canthal tendon laxity.
