Problems solved by technology
Conventional microscope-integrated OCT systems can be designed for wide-field viewing systems and are therefore difficult to implement with the narrow field of view of macular contact lenses
For example, when a macular contact lens is in place, OCT imaging may be affected because the range of the OCT scanning beam is limited by the pupil of the patient's eye

Embodiment Construction
[0020] In the following description, specific details are set forth to describe certain embodiments. It will be apparent, however, to one skilled in the art that the disclosed embodiments may be practiced without some or all of these specific details. The specific examples presented are intended to be illustrative, not restrictive. Those of ordinary skill in the art will recognize that other materials, although not explicitly described herein, are within the scope and spirit of the disclosure.
[0021] The present disclosure describes devices, systems and methods to facilitate and optimize simultaneous widefield OCT imaging and direct visualization using a surgical microscope with a macular contact lens in place. An ophthalmic lens and a miniature lens may be provided between the surgical microscope and the surgical eye. Ophthalmic lenses and miniature lenses can work with macular contact lenses to aid in both OCT imaging and directional visualization without changing the co...

An ophthalmic visualization system can include an ocular lens positioned between a macular contact lens coupled to a procedure eye and a surgical microscope. The ocular lens can guide a light beam through the macular contact lens and into the procedure eye, and in combination with the macular contact lens generate an intermediate image of the procedure eye at an image plane between the procedure eye and the surgical microscope. The system can include a reduction lens positioned in the optical path between the surgical microscope and the ocular lens. The reduction lens and / or ocular lens can align a focus plane of the surgical microscope with the image plane. A method of visualizing a procedure eye in an ophthalmic procedure can include positioning an ocular lens and a reduction lens between a macular contact lens and a surgical microscope; and scanning the procedure eye with a light beam.
Description
technical field [0001] Embodiments disclosed herein relate to ophthalmic visualization systems. More specifically, embodiments described herein relate to ophthalmic surgery utilizing a macular contact lens associated with the eye being operated on. An ophthalmic visualization system can simultaneously scan a target area within an operating eye using a light beam, such as an optical coherence tomography (OCT) scanning beam, and directly observe the target area using a surgical operating microscope. Background technique [0002] Some types of eye surgery involve the use of macular contact lenses. These procedures may include macular surgery for the treatment of membrane peels, macular holes and / or epiretinal membranes, among other ophthalmic conditions. During the procedure, the surgeon looks at the operated part of the patient's eye through a surgical operating microscope. When the macular contact lens is attached to the eye, the surgeon sees an upright virtual image of th...
