Before choosing to have elective LASIK vision correction surgery, it is essential that you have a comprehensive eye exam and LASIK consultation.
The eye exam may be performed separately by your family eye doctor, or both the exam and the LASIK consultation could be performed the same day by your LASIK surgeon or an eye doctor employed by the surgeon or the laser center.
During the comprehensive eye exam, your doctor will determine your eyeglass prescription and evaluate of the health of your eyes to make sure you are a good candidate for LASIK. Your pupils will be dilated during this exam — both to thoroughly examine the interior of your eyes and to relax the focusing mechanism of the eye to get the most accurate measurement of your refractive error.
During the pre-op consultation, additional measurements of your eyes will be taken to confirm you are a good candidate for the procedure. In particular, because LASIK reshapes the clear front surface of the eye (cornea), detailed corneal topography measurements of the shape and thickness of your corneas will be performed to confirm it is safe for you to have LASIK surgery.
Also, wavefront measurements will be conducted to determine the type and amount of higher-order aberrations in your eyes and whether a custom LASIK procedure is advisable.
An analysis of your tear film will be performed to detect any possible dry eye problems and treat them prior to LASIK surgery to avoid dryness-related complications.
Also, a close inspection of your eyelids will be performed to detect and treat any blepharitis that could increase your risk of LASIK complications.
A simple test to determine your dominant eye also will be performed. This is especially important if you have presbyopia and are considering monovision LASIK or multifocal LASIK so you have less need for reading glasses after surgery.
