INSTRUMENT FOR OBJECTIVE MEASUREMENT OF REFRACTIVE WAVEFRONT ABERRATION, SURGICAL MICROSCOPE, AND SLIT LAMP

摘要

PROBLEM TO BE SOLVED: To provide an instrument for objective measurement of refractive wavefront aberration facilitating the confirmation of a visual field or the recording of eye movement and capable of being also combined with a device other than a surgical microscope.SOLUTION: The instrument for objective measurement of refracted wavefront aberration includes a wavefront measuring system having a light source 100 for irradiating the eyeground of an eye to be examined with illumination light, a Hartmann diaphragm 120 for dividing the reflected light flux reflected from the eyeground of the eye to be examined into a plurality of light fluxes and a light detection part 122 for detecting the divided light fluxes divided by the Hartmann diaphragm 120 and further includes an anterior eye part observation system having a light source 112 for illuminating the anterior eye part of the eye to be examined and a light detection part 114 for detecting the light reflected from the anterior eye part of the eye to be examined. Then, an object lens 108 functions as the object lens common to the wavefront measuring system and the anterior part observation system.
