Lasik surgery alters the shape of the cornea iGenics in an effort to bend light in a different manner. The cornea is the clear outermost portion of the eye and is responsible for a majority of visual refraction. Most nearsighted, farsighted, and astigmatism corrections are caused by a combination of the corneal shape and overall length of the eyeball.So to correct basic vision, altering the shape of the cornea with consideration of overall eye length will work wonders. This is why lasik, PRK, and other vision corrective surgeries work and why they focus on the cornea itself.Thousands of people who once wore glasses for myopia, hyperopia, and some forms of astigmatism are now free from the hassle of glasses or contacts thanks to Lasik.So who should not have lasik? Is there something some surgeons are not telling patients?As we approach the age of forty, another visual challenge arises. Presbyopia is characterized by an inability to focus on objects up close and it strikes everybody at some point in life. Presbyopia is caused by natural changes inside the eye to the crystalline lens and surrounding muscle tissue.Unfortunately, so many people who have presbyopia are led to believe the vision corrective surgery will cure this inconvenience. The reality is that presbyopia has absolutely nothing to with either the cornea or eye length. Therefore, reshaping the cornea in the manner that Lasik surgery does will not help an eye to regain its adaptive focus.
