or Lasik (laser-assisted in situ keratomileusis) is a type
of refractive laser eye surgery performed by ophthalmologists for
correcting myopia, hyperopia, and astigmatism. The procedure is
generally preferred to photorefractive keratectomy, PRK, (also called
ASA, Advanced Surface Ablation) because it requires less time for the
patient's recovery, and the patient feels less pain overall. However,
there are instances where a PRK/ASA procedure is medically justified as
being a better alternative to LASIK.
Many patients choose LASIK as an alternative to wearing corrective eyeglasses or contact lenses.
What is the Initial Lasik Eye Exam Like?
The first significant step before the Lasik surgery is to have a comprehensive eye examination, in order to be sure that you are a good candidate for the Lasik procedure. A map of your eye will be created during this exam. This map is used in order for the Lasik physician to determine how to reshape your eye to give you the clearest post-operative vision possible.
This eye exam will do several things. Your eyes will be dilated in order to see if there are any irregularities within the eye itself. The thickness of the cornea will be measured, and a precise map of the cornea will be generated.
The "refractive error" (or the reason why your vision isn't currently perfect) will be accurately analyzed in order for the Lasik procedure to get the best results possible. Finally, how your eyes generate tears will be closely looked at, as good tear production is essential for the health of every eye.
Before or after these measurements, the Lasik physician will discuss your past medical history to see any previous operations or any ongoing health problems. A few chronic conditions may make the Lasik procedure not a good option for some people, and also women currently expecting should wait for some time after delivery. The physician also will discuss the expectations the Lasik client has about the operation and subsequent changes in their lifestyle.
Though most people pass through this Lasik eye exam with flying colors, be prepared for some suggestions or serious discussion. Your eye map may indicate that a newer form of Lasik procedure might be better, such as one that generates a three dimensional waveform for each eye. Tear production issues may indicate that the Lasik procedure is not the best option for you, and the Lasik physician may recommend another solution.
If all goes well and the Lasik procedure is scheduled, the physician will review the treatment plan and what the client should do to prepare for the Lasik surgery. This plan may vary slightly between patients, but in general will look something like the schedule below. Always follow the recommendations of your Lasik physician closely.
contact lenses should be avoided for several weeks prior to Lasik vision
correction, since contacts can slightly affect the shape of your cornea.
It is important to let your eyes rest in order to get the most accurate
Lasik vision improvement possible. Hard contacts should be avoided for a
month, soft contacts for at least two weeks.
Stop using any lotions, makeup, or anything else that could possibly get into the eye the day or two before surgery. It is important to have your eyes as rested as possible before the Lasik operation. Also, arrange for someone else to drive you home after the Lasik procedure itself.
These are the most common steps to prepare you for an easy and successful Lasik procedure. Make sure you give the doctor all information needed for your case, and follow his directions closely. The Lasik procedure will give you a new outlook in life!
