Learn about Visual Disorders and their LASIK treatments in Philadelphia PA. Nearsightedness, Farsightedness, Astigmatism & Presbyopia treatments. With Nearsightedness or Myopia, rays of light are not focused on the BACK of the eye falling in FRONT of its focusing point on the Retina thus causing Blurriness for distance vision. We correct Myopia by forcing or “pushing” the focus point back properly on the Retina to achieve clear vision. This is often done with visual aides such as glasses & contact lenses. With LASIK, the focus point is forced BACK onto the Retina allowing proper focusing of the eye WITHOUT visual aides & resulting in CLEAR Vision WITHOUT any visual aides! This is accomplished with LASIK by FLATTENING the curvature of the cornea with the laser beam.
