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 configured to provide at least one treatment light and an anti-startle light of visible colored light from the light source device, the treatment light being selected from 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 operation of the light source device to provide discontinuous treatment light projection onto an eye of a patient under treatment for a selected treatment time comprising successive treatment light exposure periods of a first light intensity level separated by non-treatment periods at a second light intensity level lower than the first light intensity level and to switch on the anti-startle light to be directed towards the eye of the patient during the non-treatment periods and switch off the anti-startle light during treatment light exposure periods.

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.

13. A method of producing a treatment light for use in phototherapy treatment of an eye, comprising:
-
directing at least one light beam of at least one predetermined wavelength band from a light source along a predetermined light path from the light source to an outlet of at least one optical treatment head; projecting the light beam from the outlet of the at least one optical treatment head towards one eye of a patient and focusing the beam to produce at least one light spot of predetermined size and shape on the eye at a predetermined working distance from the at least one optical treatment head, whereby the at least one optical treatment head is positioned at a distance from the eye sufficient to allow access to the eye; and controlling the light source or projected light beam to provide discontinuous treatment light projection onto the eye for a selected treatment time, the discontinuous treatment light projection comprising successive treatment light exposure periods of a first light intensity level separated by non-treatment periods at a second light intensity level lower than the first light intensity level, wherein the discontinuous treatment light is selected from a group consisting of UVA light, blue light, and a mixture of UVA and blue light; and projecting an anti-startle light of visible colored light from a second light source to be directed towards the eye during the non-treatment periods. - View Dependent Claims (14, 15, 16, 17)

18. An ophthalmic treatment system, comprising:
-
a light source device; first and second optical treatment heads operatively coupled to the light source device, and configured to provide at least one treatment light, the treatment light being selected from 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 operation of the light source device to provide discontinuous treatment light projection onto an eye for a selected treatment time comprising successive treatment light exposure periods of a first light intensity level separated by non-treatment periods at a second light intensity level lower than the first light intensity level; and a height adjustable support stand, a first adjustable arm including a flexible, adjustable gooseneck supporting the first optical treatment head on the support stand and a second adjustable arm including a flexible, adjustable gooseneck supporting the second optical treatment head on the support stand, each optical treatment head comprising a housing having a lower surface including a UVA/blue light output port and first and second positioning light output ports on opposite sides of the UVA/blue lightoutput port, the first and second positioning light output ports configured to emit angled light beams of two different colors which cross over at the predetermined working distance from the treatment head in alignment with the UVA/blue light output port.
