1. A method for promoting recovery of retinal tissue in an eye of a patient exhibiting dry age-related macular degeneration, said method comprising:
- delivering two or more light dosages of different wavelengths onto retinal tissue in an eye of a patient exhibiting dry age-related macular degeneration;
wherein each of said two or more light dosages is of at least 10−
2 J/cm2,wherein a first light dosage of said two or more light dosages has a first wavelength of visible light between approximately 577 nm and 597 nm and a second light dosage of said two or more light dosages has a second wavelength of visible light between approximately 640 nm and 700 nm,wherein each of said two or more light dosages is of sufficient energy density to modulate one or more cellular activities in said retinal tissue and to promote the recovery of said retinal tissue.

Abstract
An ophthalmic phototherapy device and associated phototherapy treatment method for promoting healing of damaged or diseased eye tissue. The ophthalmic phototherapy device includes a light emitting mechanism for transmitting light of at least one preselected wavelength to the eye tissue. The ophthalmic phototherapy method includes directing light of at least one wavelength for a selected period of time to a portion of damaged or diseased eye tissue, whereby the light transmitted to the damaged or diseased eye tissue stimulates cellular activity in the eye tissue to promote healing.

14. A method for promoting the recovery of retinal tissue in an eye of a patient exhibiting dry age-related macular degeneration, said method comprising:
-
directing onto said retinal tissue a continuous beam of light comprising visible light having a first wavelength, wherein said continuous beam of light is delivered for a first duration such that said continuous beam of light delivers a first dosage of at least 10−
2 Joules/cm2 to said retinal tissue anddirecting onto said retinal tissue a pulsing beam of light comprising light having a second wavelength, wherein said pulsing beam of light is delivered for a second duration such that said pulsing beam of light delivers a second dosage of at least 10−
2 Joules/cm2 to said retinal tissue andwherein each of said first and second light beams is of sufficient energy density to modulate one or more cellular activities in said retinal tissue and to promote the recovery of said retinal tissue. - View Dependent Claims (15, 16, 17, 18, 19, 20)
