Sklar's Ayer Chalazion Forceps are ophthalmologic thumb forceps used to evert the eyelid and expose chalazion for drainage and removal. The instrument has one is solid and one fenestrated tip. The tips isolate the chalazion on the elid and push it upward to aid in the procedure. The size and consistency of the chalazion are primary factors when choosing which chalazion forceps to use. Larger chalazion, as well as those with hard matter, will require larger incisions, hence require larger tipped forceps. Smaller, fluid chalazion may be excised with smaller incisions and the use of forceps with a smaller diameter. This product is available with or without a tightening screw, and the fenestrated ring diameter is 8mm.
