Abstract
A retina viewing system and method of using the same includes an ophthalmic microscope, a disposable lens attachment, and an electronic control unit (ECU). The microscope has an optical head and a set of internal focusing lenses, the latter providing the microscope with a variable working distance or focal length. The disposable lens attachment includes a resilient body with a proximal end connected to the optical head and a distal end connected to a high-power/high-diopter distal lens. The ECU executes instructions for viewing a retina or other intraocular anatomy of a patient eye. Execution of the instructions causes the ECU to automatically adjust the variable working distance or focal length of the microscope when viewing an image of the retina through the distal lens.
Claims18
A disposable lens attachment for use with a retina viewing system having an ophthalmic microscope with an optical head, the disposable lens attachment comprising:
- a distal lens;
- and
- a resilient body having a proximal end configured to connect to the optical head of the ophthalmic microscope, and a distal end connected to the distal lens, wherein the resilient body is constructed of a resilient material configured to bend and collapse away from a patient eye in the event of contact therewith.
