App note: Ophthalmic surgery

Great read app note from Newport about non contact treatment for eye diseases using lasers. Link here

Ophthalmology is the branch of medicine that deals with the anatomy, physiology and diseases of the eye. The laser is particularly suited to ophthalmic surgery since it can provide a non-contact method of interacting with the cornea or even the interior of the eye, including the lens and the retina. Laser photocoagulation surgery is used to treat several eye diseases and has become widely used in recent decades. Treatments for diabetic retinopathy and macular degeneration have also been accomplished with several kinds of lasers including ion lasers, dye lasers, and laser diodes. Recently, two forms of ophthalmic surgery have attracted great attention: laser-assisted in situ keratomileusis (LASIK), which is used to modify the cornea and correct vision, and cataract surgery, which can facilitate replacement of the lens when it becomes cloudy. Both procedures are accomplished with the help of ultrafast pulsed laser systems.
