These tissue sections will receive radiofrequency ablation to each eyelash follicle at a power of "low."

These tissue sections will receive radiofrequency ablation to each eyelash follicle at a power of 1.

These tissue sections will receive radiofrequency ablation to each eyelash follicle at a power of 1.5

These tissue sections will receive radiofrequency ablation to each eyelash follicle at a power of 2.

Trichiasis

The eyelid segments to be excised as part of their planned lateral tarsal strip procedure will be marked and divided into 4 equal sections (2 sections on each lid). A corneal shield will be placed into the fornix prior to treatment. Each section will be treated with the designated power setting in the following manner. The probe will be inserted into the follicle under direct visualization to a depth of approximately 1.4 mm. The designated power will be applied for 1 second. All lashes in each segment will be treated. The segments will then be excised and placed into labelled and coded containers of formalin.

Histologic Evaluation Comparing Power Settings in Radiofrequency Ablation on Eyelash Follicles

The extent of damage will be measured on the tissue sections. The diameter of abnormal/damaged tissue will be measured in microns.

The severity will be graded on a scale from 0 to 3, with 0 being no tissue changes and going up to 3 which will represent severe tissue changes.

Ochsner Health System

This will be a modified factorial trial. The tissue from all patients will be divided into 4 sections and undergo radiofrequency ablation at different settings in each section, giving us 4 groups. These 4 groups will be compared to each other.

The person examining the slides will be blinded to the power setting used.
