Abstract
The present invention provides a uniquely position adjustable ophthalmic instrument support table for use in conjunction with an examining chair and a lighting system which allows the user to program the desired room lighting independently for each of several inputs such as instrument switches, examination lights or other electrical devices used during an ophthalmic examination. The ophthalmic instrument support table includes a base unit and a table top mounted to the base unit by support structure allowing four degrees of freedom to adjust the location of the table top with respect to both the patient seated in the chair and the doctor examining the patient on the opposite side of the table. The lighting control system allows one or two circuits of room lights to be adjusted in intensity and to have this adjustment automatically recalled to set the programmed room lighting condition upon activation of the input.
