Before the actual process of conducting the LASIK surgery, the doctor will have a consultation and examination of your eyes to determine your suitability for the process. This process begins with a discussion regarding what your expectations are and what you wish to achieve by being less dependent or eliminating eyeglasses or contact lenses. Then the doctor takes a careful review of your health and eye history.
Next, in order to determine the exact prescription that will need to be treated, a refraction will be performed to measure the amount of nearsightedness or farsightedness and astigmatism. This will require the use of eye drops to get the best possible measurements. It is necessary to map the surface of the eye, called the cornea, with a corneal topographer that gives the doctor a blueprint of the shape of your eye. An important step is to measure the corneal thickness, called pachymetry, in order to help determine whether the anatomy of your cornea is appropriate for LASIK or perhaps another laser eye surgery procedure. Once all of these steps have been completed, the doctor will examine the health of the retina and inner structure of your eyes as a final check.
