  We developed a new multicoated contact lens for use with the bimanualvitrectomy technique. The new lens is made of quartz, and its multicoatedsurface has properties that decrease light reflection and increase light absorption.The lens is placed on the cornea, and the coaxial light from the operatingmicroscope alone enables surgeons to obtain a clear image of the retinal surface.This new vitrectomy contact lens is very useful for the treatment of eyeswith proliferative membranes and allows surgeons to perform vitrectomy byusing both hands.
