Ophthalmologists: Lasik in Durham NC, all of USA Safe and Effective

Numerous ophthalmologists performing Lasik in Durham, NC and other US cities concur that the procedure is one of the safest and most effective treatments for correcting either nearsightedness (myopia), farsightedness (hyperopia) or astigmatism (fully-blurred vision).

Basically, diminished vision is caused by the cornea not effectively focusing the light which enters the eye to the retina, which then transfers the image to the brain for interpretation. During the surgery, the surgeon first creates a thin, hinged flap on the cornea using an instrument called a microkeratome (a precision surgical instrument with a spinning blade). He then pulls up the flap to expose the underlying corneal tissue. This gives way for the laser to reshape the cornea into a pattern pre-determined for each patient. It is then repositioned onto the underlying tissue again.
