Short sight and long sight where people cannot see items clearly either up close or far away affects many. The reason for this defect is a cornea that is misshapen. Laser eye surgery corrects this defect so the patient doesn't need to use corrective lenses. LASIK is the most popular laser used today and was discovered in the early 90's.
Only local anaesthetic is needed with this surgery. All the surgeon needs to do is cut into the surface of the eye above the cornea, pull the flap back and reshape the cornea using the laser. Once the reshaping is done the flap is put back into place and it heal naturally.
There are lots of benefits when it comes to this procedure such as not being able to see as soon as a person wakes up. No need to buy glasses or contact lenses on a repeated basis. There is also no need to worry about the cost of replacing lost of broken glasses.
For those people who are very active and like to play sports, this form of corrective surgery is perfect. Having to wear glasses can make some heavy contact sports almost impossible and sometimes even dangerous. For those who try contacts lenses they might find that they get dry and irritable eyes a lot of the time, having their sight corrected will often eliminate this.
Not every one can have laser on their eyes however. If someone has very severe long or short sightedness then this procedure isn't for them. The patient needs to be over 21 and have a prescription that has stayed the same for around 2 years. Any previous problems or injury to the eye usually means laser is a no go.
This procedure, like most, is not risk free. There is a chance of infection, bleeding, over or under correction and sometimes even the need to have the laser eye surgery repeated later. As people get older they usually form presbyopia which cannot be treated with corrective laser.
