Patients may take other symptoms like headaches, eye fatigue, and middle strain. Vision may be worse in those with other co-existing refractive errors like astigmatism.

• Nearsightedness (myopia): Difficulty seeing distant objects.
• Farsightedness (hyperopia): Difficulty with almost vision.
• Astigmatism:Curvature of the cornea or lens is uneven, leading to distorted or blurred vision.

LASIK is a curt procedure and ordinarily completed in xxx minutes or less. Medication may exist given to sedate the patient. Anesthetic eye drops are placed in the eye and the eyelids are held open with an musical instrument. A small-scale blade or cutting light amplification by stimulated emission of radiation is used to make a pocket-sized flap in the middle. The flap is folded to give admission to the office of the cornea. A programmed laser beam is used to reshape the cornea and a small amount of corneal tissue is removed. The flap is so repositioned and heals on its own without stitches. LASIK surgery tin can be washed in both eyes simultaneously.
