Ophthalmic surgical microscope with adaptive optics for optical wavefront compensation

摘要

An ophthalmic surgical microscope can include a first light source configured to project a first light beam at an observer's eye. The microscope can include a first wavefront sensor. The first wavefront sensor can be configured to determine aberrations in the first reflection wavefront of a reflection of the first light beam. The microscope can include adaptive optical element(s). The adaptive optical element(s) can be controlled to modify the phase of incident light. The microscope can include a computing device in communication with the first wavefront sensor and the adaptive optical element(s). The computing device can be configured to generate the control signal to compensate for the aberrations and to provide the control signal to the adaptive optical element(s). A second light source and second wavefront sensor can be provided to compensate for aberrations of a subject's eye.

1. An ophthalmic surgical microscope disposed in an optical path between an observer and a subject, comprising:
a first light source configured to project a first light beam at an eye of the observer, a reflection of the first light beam from the eye of the observer including a first reflection wavefront; a first wavefront sensor disposed in an optical path of a reflection of the first light beam from the eye of the observer, the optical path of the reflection at least partially overlapping the optical path between the observer and the subject, the first wavefront sensor being configured to determine aberrations corresponding to the eye of the observer in a first reflection wavefront of the reflection of the first light beam; a second light source configured to project a second light beam at an eye of the subject; a second wavefront sensor disposed in an optical path of a reflection of the second light beam, the second wavefront sensor being configured to determine aberrations corresponding to the eye of the subject in a second reflection wavefront of the reflection of the second light beam, the second wavefront sensor distinct from the first wavefront sensor; an adaptive optical element disposed in the optical path between the observer and the subject, the adaptive optical element being configured to modify the phase of incident light to compensate for the aberrations in the first reflection wavefront and the second reflection wavefront in response to a plurality of control signals; and a computing device in communication with the first wavefront sensor and the adaptive optical element, the computing device being configured to:
generate a first control signal to compensate for the aberrations in the first reflection wavefront;provide the first control signal to the adaptive optical element;generate a second control signal to compensate for the aberrations in the second reflection wavefront;provide the second control signal to the adaptive optical element.
