Ophthalmic treatment device, system, and method of use
First Claim
1. An ophthalmic treatment system, comprising:
- a light source device;
at least one optical treatment head operatively coupled to the light source device and defining an optical axis, and providing at least one treatment light concentric to the optical axis, the treatment light being selected from the group consisting of UVA light, blue light, and a mixture of UVA and blue light;
at least one processor associated with the light source device and programmed to control the treatment light to provide discontinuous treatment light projection onto an eye for a selected treatment time comprising successive treatment light exposure periods separated by non-treatment periods, wherein the treatment light exposure periods and non-treatment periods are of equal duration; and
a photosensitizer for application to the eye to promote corneal cross-linking during UVA light exposure periods, the photosensitizer comprising a riboflavin solution containing iodide ion wherein the treatment light exposure periods and non-treatment periods of are 15 seconds.

Abstract
Ophthalmic treatment systems and methods of using the systems are disclosed. The ophthalmic treatment systems include (a) a light source device; (b) at least one optical treatment head operatively coupled to the light source device, comprising a light source array, and providing at least one treatment light; and (c) a light control device, which (i) provides patterned or discontinuous treatment light projection onto an eye (e.g., the cornea and/or sclera of an eye); or (ii) adjusts intensity of part or all of the light source array, providing adjusted intensity treatment light projection onto an eye (e.g., the cornea and/or sclera of an eye). The at least one treatment light promotes corneal and/or scleral collagen cross-linking.
