About Refractive Error and Surgery

Refractive eye surgery reduces the need for glasses or contacts, either by reshaping the cornea or replacing the lens inside the eye. Via detailed preoperative corneal mapping, the refractive specialists at Ticho Eye Associates create an individualized plan for your unique visual needs. Refractive surgery can be an incredibly rewarding decision; however, not everyone is an appropriate surgical candidate. At Ticho Eye Associates, we are very protective of your vision, so we begin with a thorough consultation to help determine if LASIK / PRK surgery is the best choice for you.

Refractive Error Treatments

Ticho Eye Associates offers the following treatments for common refractive errors:

  • Glasses, including “digital” and high-index lenses

  • Contact lenses, including toric, gas-permeable, and specialty lenses

  • Eye surgery: LASIK, PRK, and refractive lens exchange

For most people, corrective eyewear — glasses and contact lenses — is all that is needed to provide sharp, healthy vision. Depending on your unique refractive error, age, and overall eye health, minimally invasive surgery, such as LASIK or PRK, may reduce or eliminate the dependency on corrective lenses. Some patients may be appropriate candidates for refractive lens exchange (RLE).


Different techniques have evolved over the years to surgically treat refractive errors, the most common being LASIK and PRK. LASIK stands for laser-assisted in-situation keratomileusis and is perhaps the best-known of these techniques. High energy, short-pulse laser light bursts precisely cut a flap in the cornea (the transparent part of the eye on which contact lenses are placed) and then reshape the corneal “bed”. By altering the overall corneal shape, the focusing power of the cornea is modified to enhance vision. LASIK surgery is virtually painless, taking only about 15 minutes per eye to reduce or eliminate the need for eyeglasses or contact lenses.

The surgeons at Ticho Eye Associates offer PRK (photorefractive keratectomy), a refractive operation similar but often preferable to LASIK. PRK reshapes the corneal surface without creating a separate flap. PRK has been around longer than LASIK and may provide more stable results than LASIK. Many patients do not qualify for LASIK, due to thin corneas, very high myopia, and military or other occupational limitations. For these patients, PRK offers a safe and effective method of correcting myopia and astigmatism. PRK eliminates the risk of flap-related complications and reduces side effects such as glare and halos.
