OPHTHALMIC MEASUREMENT APPARATUS

摘要

An ophthalmic measurement apparatus having an instrument axis and comprising (A) a central housing comprising at least two reference surfaces and comprising a beam splitter, the instrument axis extending from the central housing, (B) a camera subsystem having a reference surface, the camera subsystem coupled to one of said reference surfaces such that the reference surface to which the subsystem is coupled and the camera subsystem reference surface together operatively align the camera with the instrument axis, and (C) an aberrometer subsystem having a reference surface, the aberrometer subsystem coupled to one of said reference surfaces such that the reference surface to which the aberrometer subsystem is coupled and the reference surface of the aberrometer subsystem together operatively align the aberrometer subsystem with the instrument axis.
