Abstract
The present invention relates to the field of diagnostic equipment in the ophthalmic field, and more precisely has as its object a multifunctional apparatus capable of performing measurements, examinations and even operations of various kinds on the eye of a patient.
Claims12
An ophthalmic apparatus comprising a plurality of optical devices including optical instruments, optical heads, or any combination thereof for measuring or evaluating a characteristic of an eye of a subject, each optical device of said plurality of optical devices having its own instrument optical axis, said plurality of optical devices being mounted on a frame comprising a base defining a resting plane for resting on a horizontal surface, and a carousel rotatable with respect to said frame about a carousel axis of rotation parallel to said resting plane, said plurality of optical devices being arranged on said carousel so that their respective instrument optical axes are parallel to said carousel axis of rotation, the apparatus comprising drive and control means, wherein:
- said carousel is supported by said frame so that said carousel axis of rotation is movable at least with respect to a height direction orthogonal to said resting plane;
- said control means being configured to perform a selective optical alignment of said plurality of optical devices with a patient's eye according to a laterality direction parallel to said resting plane and orthogonal to said rotation axis, by means of a position adjustment that combines a rotation of said carousel around said carousel axis of rotation and a displacement of said carousel axis along said height direction, wherein said carousel is supported by said frame such that said carousel axis of rotation is fixed to the frame with respect to said direction of laterality, and wherein one optical device of said plurality of optical devices is mounted on said carousel so as to be rotatable with respect thereto about said instrument optical axis of said one optical device relative to said carousel, wherein said one optical device is adapted to recover an inclination taken due to a corresponding rotation of the carousel about said carousel axis of rotation, by means of a counter-rotation of said one optical device about said instrument optical axis.
A method for optically aligning with a patient's eye an optical device of a plurality of optical devices of an ophthalmic apparatus, said plurality of optical devices comprising optical instruments, optical heads, or a combination thereof, each of the plurality of optical devices having its own instrument optical axis, said plurality of optical devices being mounted on a frame comprising a base defining a resting plane on a horizontal surface, and a carousel rotatable with respect to said frame about a carousel axis of rotation-parallel to said resting plane, said plurality of optical devices being arranged so that said instrument optical axes are parallel to said carousel axis of rotation, the apparatus comprising drive and control means, wherein:
- said carousel is supported by said frame so that said carousel axis of rotation is movable only with respect to a height direction orthogonal to said resting plane;
- the method providing to perform a selective optical alignment of one optical device of said plurality of optical devices with a patient's eye according to a lateral direction parallel to said resting plane and orthogonal to said axis of rotation, by means of a position adjustment of said one optical device that combines a rotation of said carousel about said carousel axis of rotation and a displacement of said carousel axis of rotation along said height direction, and wherein said one optical device is rotated with respect to said carousel about said instrument optical axis of said one optical device, recovering an inclination taken due to a corresponding rotation of the carousel about said carousel axis of rotation, by means of a counter-rotation of said one optical device about said instrument optical axis.
