WIDE FIELD FUNDUS CAMERA
20190167098 · 2019-06-06 · ·

A wide field fundus camera is disclosed to implement multiple illumination beam projectors and to capture multiple retinal images at a various viewing angles to mimic wide field retinal examination with an indirect ophthalmoscope. The wide field fundus camera may incorporate a consumer image recording device with fast auto focusing so as to make the device quick to respond and easy to use. The wide field fundus camera may include narrow and broad slit beam illuminations to enhance autofocusing and imaging through less transparent crystalline lens and through haze due to Purkinje reflections from crystalline lens surfaces. Control of multiple illumination beam projectors in a programmable manner can be used to assess alignment of each illumination beam projector with the eye and to capture said multiple retinal images. Furthermore, a method is disclosed to montage said multiple retinal images into a single montage and to remove haze and reflections.

VIEWING CONTACT LENSES WITH INTEGRATED SPECULUMS
20240215814 · 2024-07-04 ·

Aspects of the present disclosure relate to an integrated contact lens apparatus for ophthalmoscopic examination comprising a lens portion, an upper speculum portion, and a lower speculum portion, and methods of use thereof. The integrated contact lens apparatus facilitates improved visualization of the peripheral retina, including the superior and inferior hemiretinas, via both manual examination and wide-angle cameras that may utilize contact lenses for viewing. The integrated contact lens apparatus further prevents or reduces corneal drying and patient discomfort during examination.

Mechanical support of an indirect contact lens by a surgical microscope during vitreoretinal surgery
10285588 · 2019-05-14 · ·

An indirect contact lens is mechanically coupled to a surgical microscope during ophthalmic surgery, such as vitreoretinal surgery. The indirect contact lens rests on a cornea of an eye of a patient during the surgery but is supported by a surgical microscope attachment having multiple degrees of freedom to accommodate small movements of the eye while remaining aligned to an optical axis of the surgical microscope.
