Astigmatism is the inability to focus on objects clearly at any distance. With astigmatism the cornea is shaped more like a football than a basketball. LASIK corrects this oval shape, making the cornea more round so images can be properly focused on the retina (the back of the eye).
Nearsighted people see close objects clearly – but not distant objects. In nearsightedness, the curve of the cornea is too steep so images are focused in front of the retina. LASIK corrects this condition by flattening the curve of the cornea.
Farsighted people see distant objects clearly, but all other objects are blurred. In farsightedness, the shape of the cornea is too flat so light rays are focused behind the retina. LASIK corrects this condition by shaping the cornea so that light focuses correctly.
Sometime between age 40 and 50, most people experience a condition called presbyopia. This is not a refractive error; it is caused by the eye lenses losing flexibility over time, making it harder to see up close. Presbyopia can occur in anyone’s eyes – even if you have had successful LASIK in the past or if you had perfect vision your whole life. Reading glasses help this condition; however, not everyone is thrilled about wearing them. While LASIK in the traditional sense cannot correct presbyopia, a special LASIK technique known as monovision can provide the ability to see both close-up and far away. In this process, one eye is corrected for near vision and the other eye is corrected for distance vision.
