Abstract: A system for delivering light to a curved surface of a tissue of a subject. The system includes a light source; an optical coupler coupled to the light source; and a flexible waveguide coupled to the optical coupler. The waveguide has a first end and a second end with an elongated flat portion therebetween. Light from the light source is emitted substantially uniformly from along the elongated flat portion of the flexible waveguide, thereby delivering light substantially uniformly along the curved surface of the tissue.

Abstract: System, method, arrangement and non-transitory computer-accessible can be provided for, e.g., effecting refractive changes of the cornea by spatially-selective two-photon crosslinking of collagen fibers. For example, it is possible to obtain at least one property of at least one portion of the eye using at least one first arrangement. Based on the at least one property, data indicating a plan of affecting the portion(s) of the eye can be generated. Further, it is possible to control at least one electromagnetic-radiation-providing second arrangement to execute the plan and irradiate the at least one portion based on the plan. The irradiation can be selectively controlled to be delivered to at least one selective depth within the portion(s).
