PRK and Lasik

With the advent of the excimer laser, refractive surgery is opening up new lifestyle choices to people who were previously dependent on spectacles or contact lenses for clear vision. Utilizing the accuracy and precision of the computer-controlled excimer laser, photo refractive keratectomy (PRK) or laser in-situ keratomileusis (LASIK) changes the shape of the cornea to improve the way light is focused by the eye, correcting both myopia and astigmatism.

PRK is for candidates with low to moderate degree of myopia and LASIK is ideal for those with high degrees of refractive error. Dr Hardia has been performing excimer laser surgery since 1990 with excellent results. PRL or LASIK is performed as an outpatient in the comfort and convenience of our Excimer Laser Center. The entire procedure takes less than 10 minutes. The procedure is performed using anesthetic eye drops. Some patients see a dramatic improvement in their vision within the first few days. Most patients return to normal activities within one week.

About Photo refractive Keratectomy (PRK)

PRK uses the computer-controlled accuracy and precision of the excimer laser to sculpt the surface of the cornea, correcting both myopia and astigmatism. Because a very thin layer of the cornea is removed, PRK does not weaken the eye.

About Laser In-situ Keratomileusis (LASIK)

LASIK is a modification of PRK. First, it uses an instrument called a microkeratome to create a thin flap of corneal tissue. This flap is folded to the side and the excimer laser is then used to remove tissue from the exposed surface, correcting myopia and astigmatism. The corneal flap is then replaced.

Ideal Person for Excimer Laser Surgery?

In general, the ideal candidate for PRK and LASIK is over 18 years of age and has healthy corneas. Candidates should not have had a significant increase in their spectacle prescription within the last 12 months. People with certain medical conditions or women who are pregnant may not be good candidate for refractive surgery. Doctor can determine if you are a suitable candidate for excimer laser surgery after a preliminary consultation and examination.

The Truth

The decision to have PRK or LASIK is an important one that ultimately, only you can make. It is important that you have realistic expectations and that your decision is based on facts, not hopes or misconceptions. The goal of refractive surgery is to reduce your dependence on spectacles or contact lenses. It does not always create perfect vision. It cannot correct a condition known as presbyopia, which normally occurs around age 40 and may require the use of reading glasses. In fact, people over 40 years old who have had their myopia reduced with refractive surgery may find that they need reading glasses after procedure. Doctor will provide you with additional information that will allow you to make an informed decision.
