If you are like the thousands of Americans who undergo a vision correction procedure every year, you know that a life of clear vision without the hassle of glasses and contacts would be a tremendous benefit. Glasses tend to get dirty, lost, or broken, especially for people who like to participate in sports and other outdoor activities. Other people simply don’t like the way they look, and what’s more, they don’t like the way they see in glasses.

Contact lenses have limitations as well: daily maintenance, recurring cost, cleaning, and care. If contacts aren’t cared for properly, they have the potential to put the eye at risk of severe infections and scarring. For other people, contacts simply aren’t comfortable in the eye. Many people need vision correction due to particular jobs or hobbies. For example, it is not ideal to wear glasses or contacts if you are a military sniper in a fox hole or an offensive tackle in the trenches of a football game.

Advanced Vision Correction: Know Your Options



In its most classic form, LASIK surgery (laser-assisted in situ keratomileusis) employs a specially-calibrated, computer-guided laser to treat nearsightedness, farsightedness, and astigmatism. It is a procedure that permanently improves the shape of the cornea, the clear covering of the front of the eye, using an excimer laser. In nearly all cases, LASIK is pain-free and takes about 8-10 minutes for both eyes. It is currently the most commonly performed vision correction procedure across the world.

The LASIK procedure works by reshaping the cornea to enable light rays entering the eye to focus properly on the retina. Numbing eye drops are applied to the surface of the eye and the surgeon creates a thin circular flap in the cornea. The surgeon then folds back the hinged flap to access the underlying corneal tissue. Using a highly specialized laser with a cool ultraviolet light beam, the surgeon reshapes a small amount of tissue to improve the focusing power of the cornea. After reshaping the eye, the flap is replaced to serve as a type of natural bandage.

LASIK is performed on each eye separately, with each procedure taking only about five minutes. Most patients experience little or no discomfort after LASIK. In as short as 24-hours, patients typically enjoy vision of 20/20 or better without glasses or contacts.

2. Implantable Contacts: Visian ICL

Visian ICL process

The Visian ICL (Implantable Collamer Lens or Implantable Contact lens) is an advanced form of vision correction providing ultra-hi def vision to correct nearsightedness and astigmatism. The Visian ICL produces excellent vision results. In fact, many top-performing athletes, Olympians, and US Military snipers have embraced the Visian ICL procedure because of the reliable visual clarity it achieves. Implantable lenses function similar to contact lenses to correct poor vision. They are able to produce superior vision results because they help the natural lens of the eye work better, without the need for removal or permanent reshaping of any part of the eye.

The Visian ICL is designed to offer permanent vision correction without the need for any maintenance in the future. One unique thing about the Visian ICL is that it can be removed or replaced if vision needs change over time. The clear lenses are placed behind the iris and in front of the natural lens. This enables light to focus properly on the retina. As an added benefit, the Visian ICL lens material contains UV protection that blocks harmful UV rays.

Unlike contacts, patients cannot feel the Visian ICL in their eyes. Apart from regular eye exams, the Visian ICL typically does not require any maintenance. Because the Visian ICL is placed behind the iris, it cannot be seen in the mirror and is undetectable to onlookers. After the 15-minute outpatient procedure, patients usually experience an immediate improvement in their sight. Recovery time is usually pain-free and short.

Visian ICL Quick Facts:

  • Dr. Parkhurst is the only surgeon in Texas, and 1 of 5 in North America in the “Visian ICL Master’s Club”, having implanted more than 1,000 ICLs
  • ICL is designed to be a permanent procedure, yet removable if vision needs change
  • Superior Vision Quality & Better Night Vision compared to glasses & contacts
  • Less Chance of Dry Eyes compared to contact lenses
  • Quick recovery and results
  • Maybe ideal for patients with thin or unusually shaped corneas
  • Maybe the ideal option for patients with dry eyes from their contacts
  • Nearly 20 years of experience with ICLs approved both internationally, and approved by the US FDA in 2005

3. Advanced Surface Ablation (PRK)

Woman about to have PRK surgery

PRK (photorefractive keratectomy) is the predecessor to LASIK. It is still commonly performed and may offer advantages over contacts and glasses for some patients with nearsightedness, farsightedness or astigmatism. The idea behind PRK is the same as LASIK, using a laser to correct the shape of the cornea to improve how light enters the eye and focuses on to the retina. What’s unique about PRK is how the surgeon reaches the cornea. During a LASIK procedure, the surgeon uses a laser to create a thin hinged flap on the outer surface. With PRK, the thin regenerating layer on the outside of the cornea is temporarily pushed aside, giving the surgeon access to the main part of the cornea to reshape. The surface naturally grows back in a few days.

PRK typically takes about 10 minutes to complete. Recovery time is usually a few weeks.

PRK Quick Facts:

  • May be suitable for some patients with a thin cornea
  • Longer recovery compared to LASIK

Making the decision to have vision correction surgery is a big one. Every person considering the procedure is encouraged to investigate fully all of the potential advantages, disadvantages, benefits, and risks with a qualified and licensed physician. According to the US Food and Drug Administration, risks of LASIK and PRK can include dry eye syndrome, which can be severe; the possible need for glasses or contact lenses after surgery; visual symptoms including halos, glare, starbursts, and double vision, which can be debilitating; and the loss of vision. In our experience, these risks are extremely rare when patients are selected properly, and those who may not be good candidates are instructed they may have different risks if they remain in their glasses and contact lenses to see. We have trained professionals on staff, willing, able, and happy to answer any of your questions. Simply call 210-615-9358 or complete our web form to have someone from our office contact you today.
