Considering Lasik?

The Grene Laser team has helped thousands of people around Wichita enjoy great vision without the hassle of glasses or contact lenses by reducing their nearsightedness, farsightedness and/or astigmatism with LASIK. We combine experience and laser vision correction technology, with a strong commitment to great patient care. Many patients experience natural, 20/20 vision for the first time since childhood (results may vary).

If you or someone you know is interested in learning more about LASIK, schedule a free consultation to determine if you are a good candidate for LASIK. Our consultations last about an hour to develop an individualized treatment plan for your best vision.

You might be surprised to know not everyone qualifies for LASIK. That’s part of the reason we offer a free consultation. This simple checklist helps you understand if you’re a good LASIK candidate. You’ll need to know a bit about your eye health to be able to answer all the questions.

“My extremely active lifestyle made it difficult for me to manage my vision with glasses and contact lenses. Since surgery my vision is crisp and clear. I can honestly say that laser surgery was one of the best decisions I have ever made.”
Nick Moore, Salesman / Avid Motorcyclist – Wichita, KS

“Even with contacts correcting my poor vision I still had problems with halos around runway lights at night. Immediately after surgery I could see better than I ever had. My vision is better than perfect and halo free.”
Kristen Lingg, Pilot – Wichita, KS

“After having to wear contacts for 20 years, I knew it was time to throw them away when I became a firefighter. I now wake up to respond to an alarm with clear vision and I don’t have to worry about my eyes. It truly was an amazing and life changing experience.”
Justin Best, Newton Fire / EMS – Newton, KS

“Playing sports is hard enough without worrying about your contacts. The inconvenience of losing contacts during practice and competition was frustrating for me. The decision to have the surgery was the best decision I have made!”
Shalee Lehning, K-State Women’s Assistant Coach / Former WNBA and K-State Player – Manhattan, KS

Financing Options

Putting off vision care postpones wellbeing. It doesn’t have to be that way. CareCredit is an excellent method of financing your LASIK surgery. A couple of advantages of using CareCredit include: one easy credit card with over 150,000 places to use it, special financing rates available, and you will receive a credit decision within minutes of applying. Find out more about CareCredit.

Flex Savings Accounts (FSA)
Flex Savings Accounts can also be used for LASIK! LASIK is that much more affordable when it is paid for using pre taxed dollars. Cash and check payments While the convenience of using your FSA or CareCredit accounts are a nice option, sometimes patients are in a position to pay in full with cash or check. Patients who choose this option can receive up to a $200 discount on their procedure. Ask for details at your first appointment.
