An ophthalmic illumination/observation device for use in ophthalmology, which consists of a bi-concave contact lens with a front concave surface that matches an external surface of a patient's eye cornea onto which the front concave surface of the bi-concave contact lens is placed during the procedure, a rear concave surface on an opposite side of the bi-concave contact lens, and a separate optical gonio lens having a distal end and a proximal end with a convex surface on the proximal end that during the procedure is placed onto the rear concave surface of the bi-concave contact lens and matches the rear concave surface of the bi-concave contact lens. Preferably, the bi-concave contact lens is made from a soft elastic plastic material. The device provides efficiency of illumination and observation and is inexpensive to manufacture.

A modular lens adapter system or kit is provided for mobile anterior and posterior segment ophthalmoscopy. Equipped with various lens adapter modules, respective lenses and a mobile imaging device, a user is provided with tools for various mobile ophthalmoscopy imaging applications. Eye care practitioners can use their existing lenses to customize the modular lens adapter system in a cost-effective way, which allows for mobile and remote capture, viewing, and utilization of clinical images. The various modules are also adaptable to nearly any type of phone or tablet regardless of its dimensions or presence of a protective case. The invention also addresses the need for fewer, smaller, less expensive, and easier to use ophthalmic imaging equipment, which is further important in enabling a broad base of users.
