Because of visual problems, people cannot do certain number of things. Like for example, swimming, flying an airplane and vigorous sports are just not for them. No matter what passion they may have for these activities, their individual safety and the safety of others just can't outweigh the passion they feel.
Fortunately, in the year around 1950, a talented ophthalmologist by the name of Jose Barraquer developed the first microkeratome. It is a procedure wherein refractive errors of the eyes are corrected by altering the shape of the cornea. This method is called Keratomileusis.
That and other breakthroughs in such field of medical science gave way to the world famous laser guided eye surgery which is no other than LASIK or laser assisted in situ keratomileusis. The results of LASIK in people with refractive errors are astounding. But because each person differs from the other, the need to have more specific procedures emerged. This paved the way for LASEK which is different from LASIK because of the finer blade used and the stroma left uncut. Further advancements gave birth to LASAK, the latest laser guided eye surgery.
This gave way to the development of LASEK. With LASEK, a much finer blade is used which can be beneficial for people with thing corneas. Also the stroma is left uncut during the LASEK procedure. LASAK however, is the latest and most advanced of all laser assisted eye surgeries.
However there are procedures that can further specify and guide the procedure. This is no other than wavefront and aspheric. Because the cornea of the eye is not round as most people think it is, doing a procedure that assumes it is may incur unwanted side effects. With the aspheric eye surgery however what happens is that the surgeon evaluates the shape of the cornea before the start of the surgery. Then he decides which laser assisted eye surgery is best to perform on the said individual. With aspheric eye surgery, the post operative cornea resembles the shape of pre operative cornea thereby avoiding spherical aberrations.
