A complete eye examination (including pupil dilation) and preoperative tests are necessary to determine the refractive power and health of your eye. In order to determine your candidacy for the LASIK procedure it is also necessary to evaluate your expectations of what refractive surgery will do for you.

If you wear contact lenses, you must stop wearing the lenses for a few weeks before the exam, usually:

  • 3 weeks for soft daily wear lenses,
  • 6 weeks for gas permeable and extended wear soft contact lenses,
  • 8 weeks for [PMMA] hard plastic lenses on at least one eye (preferably both) and wear glasses or one contact lens during this period of time.

The actual time required for removal of contact lenses may vary depending upon the doctor's recommendation for your particular case.

Contacts need to be removed in order to achieve the most accurate measurements of your natural corneal curvature. You may be required to have measurements taken every week for several weeks before LASIK surgery to be sure the cornea is stable. If your cornea stabilizes sooner than expected after the removal of the contact lens, your surgery may be done sooner.

If your evaluation exam and preoperative tests indicate that you qualify for surgery, you should discuss the following surgical options with your doctor:

  • You may choose to have LASIK surgery on one eye, and have the second eye done several days to weeks later. When the first operated eye is comfortable and sees well, and both you and your doctor are satisfied, then evaluation for LASIK surgery on the second eye can be considered.
  • You may choose to have bilateral LASIK performed. Some patients choose to have both eyes done on the same day.

If it is determined that you are not a good candidate for the LASIK surgery:

  • You will be given an explanation as to the reasons why you are not a good candidate.
  • It may be recommended that you postpone your refractive surgery until further developments take place with LASIK.
  • You may want to consider an alternative method of refractive surgery, or stay with your glasses or contact lenses for the time being.
