Abstract
A sterile hand held slit lamp for laser refractive surgery includes a charging base that charges a battery while a hand held slit lamp is positioned thereon. A sterile supple cover is positioned over a slit lamp handle while supported by the charging base. A sterile gloved operator grasps the slit lamp handle covered by the sterile cover and illuminates an eye with a slit lamp beam. In many embodiments, an operating microscope provides a view of the eye to an operator while the slit lamp beam illuminates the eye. Operator adjustable controls located on the slit lamp handle are manipulated through a sterile cover and control a length, a width and an intensity of the slit lamp beam. An operator wearing sterile gloves adjusts a position of a piece of tissue near an incision, and removes debris from a surgical incision in tissue after viewing the eye illuminated with the hand held slit lamp beam.
