The importance and medical uses of the laser beams
The laser is a device that emits light through a process of optical amplification based on the stimulated emission of the electromagnetic radiation , The laser is highly coherent , It is monochromatic in nature and the laser beams are hardly divergent .
The medical uses of lasers
The laser is used in medicine to improve the precision work like the surgery , especially it is used in the brain surgery , The operations are quick and heal quickly with using lasers , They are less painful than ordinary surgery which performed with a scalpel .
Lasers are used for photocoagulation of the retina to halt retinal hemorrhaging and for the tacking of the retinal tears , Higher power lasers are used after cataract surgery if the supportive membrane surrounding the implanted lens becomes milky.
