Ophthalmic lasers These lasers allow non-invasive treatment of diseases of the eye as well as vision correction. Vision correction utilizes an ultraviolet excimer laser to reshape the cornea. Near infrared YAG lasers or argon lasers are used to treat glaucoma by relieving intra-ocular pressure. Argon lasers are also used to treat abnormal retinal blood vessels that are common in diabetics. Macular degeneration Macular degeneration can also be treated with lasers.
Laser photocoagulation is used to seal the blood vessels and restore vision.
The procedure performed with a near-infrared YAG laser involves thermal effects and may be accompanied by damage of local tissue. A new procedure utilitzes a photosensitizer that is activated by red light to seal the blood vessels without thermal damage.
