What is the Difference Between LASIK, PRK and Clear Lens Exchange

When patents come to us to find out if they are a good candidate for LASIK vision correction we conduct a very thorough eye examination – because not everyone is a good candidate .  For example, your cornea might be too thin, or the shape of your eye might not be appropriate for LASIK.  ECT also offers PRK, which is an excellent option to improve your vision.

What is LASIK?

LASIK is the most popular surgical procedure to correct vision problems. LASIK is a type of laser vision correction performed by a surgeon using a computer-controlled laser that emits precise pulses of energy to reshape the cornea. LASIK dramatically reduces the need for glasses or contact lenses by treating nearsightedness, farsightedness and astigmatism. After LASIK, nearly all patients see well enough that they don’t need glasses or contacts for most or all activities requiring distance vision.

What is PRK?

PRK, which stands for photo-refractive keratectomy, works in exactly the same general way as LASIK by reshaping the cornea. While both LASIK and PRK are two-step processes, in PRK the first step is different. Whereas LASIK involves providing the laser treatment under a flap, PRK is the application of the laser treatment on the corneal surface.

What is Clear Lens Exchange?

This procedure is much like cataract surgery, where the natural lens of the eye is exchanged for a custom lens implant. So, when LASIK or PRK is not the best option for you, we most likely have other procedures to improve your vision!

The only way to know what procedure is right for you is to schedule a no-obligation evaluation. We will do a comprehensive set of specialized tests and talk to you about what will work best for your eyes. Our friendly LASIK Counselors and Physicians look forward to seeing you to answer all your questions.
