Compact wavefront sensor module and its attachment to or integration with an ophthalmic instrument

摘要

One embodiment disclosed is a compact wavefront sensor module to be attached to or integrated with an ophthalmic instrument for eye examination and/or vision correction procedures. The front lens for relaying the wavefront from the eye to a wavefront sampling plane is positioned at the optical input port of the wavefront sensor module. The front lens is shared by the wavefront sensor and the ophthalmic instrument, and the wavefront sensor module can be made very compact while still being able to cover a large eye wavefront measurement diopter range. Another embodiment disclosed is an ophthalmic device for measuring properties of a subject eye including an ophthalmic instrument integrated with the wavefront sensor module.

主权项

1. An ophthalmic device for measuring optical properties of an eye, comprising:
an ophthalmic instrument with or without its original objective lens, and a compact wavefront sensor configured to be attached to or integrated with the ophthalmic instrument, wherein the wavefront sensor comprises: a front lens, being the first lens of a 4-F wavefront relay, disposed at the optical input port of the wavefront sensing module; and a beam splitter configured to allow most of the light meant for the ophthalmic instrument to pass through and to reflect typically a near infrared wavefront beam from the eye to the wavefront relay path; wherein the front lens is shared by the wavefront sensor module and the ophthalmic instrument.
