Vision Correction--What are the Choices?

1. Glasses
2. Contact Lenses
3. Radial Keratotomy (RK)
4. Automated Lamellar Keratoplasty (ALK)
5. Excimer Laser Procedure (PRK - Photoreactive Keratectomy)
6. Excimer Laser Procedure (LASIK - Laser Assisted Intrastromal Keratomileusis)
7: Femtolasik
8. Customized Lasik

1 and 2 are non-surgical solutions. The rest are surgical solutions.


RADIAL KERATOTOMY (R.K.) - an older, but common surgical procedure whereby the periphery of the cornea is reshaped with a hand-held diamond blade, by placing microscopic radial incisions in the outer portions of the cornea. These fine incisions help flatten the corneal curvature, thereby allowing light rays entering the eye to properly focus onto the retina. These incisions are very small, and take only minutes to perform.


AUTOMATED LAMELLAR KERATOPLASTY (A.L.K.) -a newly introduced procedure whereby a fine microkeratome creates a corneal flap, revealing corneal tissue. A thin wedge of tissue is then removed with a second microkeratome pass. The shape of the cornea is changed through the removal of this wedge of tissue. The flap is then closed.


PHOTOREFRACTIVE KERATECTOMY (P.R.K.) - utilizes the excimer laser to gently reshape the outer surface of the cornea. Deeper cell layers remain virtually untouched. The laser can precisely reshape the cornea of the eye in seconds. This reshaping enables light rays entering the eye to focus properly onto the retina, resulting in clearer vision. Since the laser removes only a very thin layer of the cornea, the cornea keeps its original strength.


LASER-ASSISTED INTRASTROMAL KERATOMILEUSIS (L.A.S.I.K.) - utilizes the excimer laser as part of a procedure that is similar to ALK. With LASIK, a corneal flap is created, and the inner corneal tissue is precisely reshaped with the laser, altering the shape of the cornea and allowing light to be refracted properly on the retina. Air is then used to reseal the flap. LASIK is very effective for severe and extreme cases of myopia, significantly reducing the recovery time (versus PRK) and decreasing the chance of many of the procedural risks (versus ALK).

With the potential advantages of improved safety and accuracy, the excimer laser procedures are the procedures of choice for most patients.

During the consultation appointments, questions regarding various visual correction options will be answered in greater detail, and together with your doctor, you will assess which alternative is best suited for your needs.

Customized Ablation

Wavefront technology allows me to customize your LASIK treatment specifically for your eyes. Although millions of eyes may have the same refraction (glasses prescription), no two eyes will have the same wavefront pattern. Your unique wavefront pattern is programmed into the VISX Star S4 Excimer Laser, allowing customized LASIK treatment specific to your eye, increasing the precision and accuracy of LASIK.

Wavefront technology generates a computerized, 3-dimensional measurement of your eye. (We take a "picture" of your eye. You don't feel anything.) Wavefront measurements are 25 times more precise than previous measurement systems and can treat corneal imperfections that glasses or contacts cannot correct. This improves the quality of your vision after LASIK, especially at night
