Assessment of Changes of Periocular Skin Sensation Following Eyelid and Ocular Surface Surgeries

"The eyelid's sensation will be assessed at 6 points of the eyelid using the Cochet-Bonnet aesthesiometer (Luneau Ophtalmologie, Paris, France). Measurements will take place before surgery, and two weeks, three months and six months after surgery.~This instrument contains a 6 centimeters long, retractable, flexible monofilament. For any given length, when applied perpendicularly to a test surface, the filament will exert a precise pressure before visibly bending. The filament's length inversely corresponds to the pressure exerted by the aesthesiometer such that the shorter the filament length, the more pressure it exerts on the test surface."
