What is LASIK?


LASIK is an outpatient vision correction procedure that permanently reshapes the cornea to treat nearsightedness (myopia), farsightedness (hyperopia), or astigmatism.  At John-Kenyon, we perform blade-free, all-laser LASIK surgery. Our doctors have performed thousands of laser vision procedures and are dedicated to using the safest, most effective, and most advanced technology available.

The first step of the procedure, the creation of the flap, was traditionally performed by hand but is now completed using the IntraLase® FS laser. Clinical surveys have shown that the IntraLase® FS produces more 20/20 or better results.  In fact, the technology was recently approved by the U.S. Military and NASA for their pilots and astronauts.

The second step of the procedure, the reshaping of the cornea for improved vision, is completed using the state-of-the-art ALLEGRETTO WAVE® Eye-Q laser. The ALLEGRETTO laser is the fastest laser system in the U.S., taking only seconds to correct one eye.

The technology used at John-Kenyon allows us to customize treatment to the individual patient, their prescription, and their cornea, allowing for more precision and accuracy than ever before. All refractive procedures are done on an outpatient basis from our Louisville office.  The actual procedures take just a few minutes and only require a topical anesthetic, so you will not be asleep during the surgery.  A John-Kenyon team member will walk you through detailed information on caring for your eyes post-surgery, and most patients return to work the next day.

What does LASIK stand for?

If you’ve already done some research on LASIK, you know that it uses a laser. During a
LASIK procedure, doctors use an excimer laser to reshape your cornea and fix visual
refractive errors like nearsightedness, farsightedness, and astigmatism.

Our surgeons complete LASIK procedures with the assistance of the laser. The doctors at
the John-Kenyon LASIK Center are nationally recognized experts in laser vision surgery –
our namesake, Dr. Maurice John, was one of the first in the nation to perform LASIK and Dr.
Asim Piracha is credited with performing the first all-laser LASIK surgery in the state in

Many medical terms have a Latin base, and that’s just what In Situ is. This Latin term,
pronounced “in-sight-ooh” means “in its place.”

Keratomileusis is the last term in the LASIK acronym, meaning to reshape the cornea.
When combined with In Situ, it describes the LASIK procedure of shaping the cornea in the

  • Am I a good candidate for LASIK?

    The ideal candidate for LASIK is over 18 years old, has healthy corneas and a relatively stable prescription (i.e. – the same prescription for 1 to 2 years).

  • Does LASIK hurt?

    Many patients experience little to no discomfort during or after LASIK. During your procedure, you’ll have a John-Kenyon staff member dedicated to making you feel comfortable. We will, literally, hold your hand throughout the entire process.

  • What if I'm nervous?

    We work hard to maximize your comfort throughout the entire LASIK experience.  If you find that you are nervous before the procedure, we’ll offer you an oral sedative to help you relax. A staff member will hold your hand throughout the entire procedure and the John-Kenyon team is more than happy to answer your questions at any time.

  • Will I be able to see immediately?

    Many patients can read the clock across the room immediately after LASIK. That being said, your vision the first few hours after the procedure can be cloudy. That’s why we ask that you bring a friend or family member to drive you home afterwards.

    We require that you rest with your eyes closed for six hours after surgery, but the overwhelming majority of patients wake up the next morning and are able to drive without glasses or contacts to their follow-up appointment.

    Every case is unique but you can expect to experience improved vision within the first few days.

  • Does insurance cover LASIK?

    Unfortunately insurance does not cover the cost of LASIK but you can use your Flexible Spending Account (FSA) or Health Savings Account (HSA) to pay for LASIK. We also have a number of financing options available to help make LASIK fit your budget.

  • Isn't LASIK expensive?

    The upfront cost of LASIK is certainly more than a pair of glasses or an order of contact lenses but some cost comparisons show that after 10 years the costs equal out.  If you have LASIK at 28, you may not have to wear contacts ever again and only need to start wearing reading glasses like most people do in their 40’s or 50’s.
