Corrective Eye Surgery Basics

While many Panama City residents, whether strolling historic downtown or relaxing on the nearby beaches, are familiar with LASIK, there are several variations of corrective eye surgery available that may better suit individual vision correction needs. Understanding these options can help local residents discuss the best course of action with their eye doctor and surgeon.

LASIK (Laser-In-Situ Keratomileusis) is the most widely known refractive surgery, having corrected vision disorders such as farsightedness, nearsightedness, and astigmatism for over 12 million people. The procedure involves an ophthalmologist creating a circular flap in the outer layer of the cornea using a femtosecond laser or mechanical tools. The underlying corneal tissue is then reshaped by an excimer laser, and the flap is returned to its original position, acting as a natural bandage. The procedure typically takes about ten minutes per eye, with recovery times ranging from a few days to several weeks.

Bladeless LASIK, also known as all-laser LASIK, replaces mechanical cutting tools with a femtosecond laser to create the corneal flap. This method generally results in fewer complications and allows surgeons to customize the corneal flap for each patient. This advancement may make the procedure accessible to individuals previously deemed unsuitable due to thin corneas, dry eyes, or extreme nearsightedness.

Custom LASIK offers precise, individualized vision correction through wavefront technology. This technology identifies and measures tiny imperfections in the eye 25 times more precisely than conventional LASIK. A 3-D map of the patient's eye guides the laser during the reshaping process, potentially leading to better overall vision, including improved night vision, and a higher quality of vision than achievable with eyeglasses or contacts. It may also reduce post-LASIK side effects like glare and halos.

Another option is Photorefractive Keratectomy (PRK) surgery, which debuted in 1986. Unlike LASIK, PRK surgery removes the epithelium, the thin surface layer of the cornea, to reshape it with an excimer laser. This eliminates the risk of flap complications and reduces the risk of removing too much corneal tissue. Recovery from PRK is slower than LASIK because the epithelial cells need to regenerate. PRK is often a good option for patients with large pupils, dry eyes, or thin corneas. Custom PRK, utilizing wavefront technology, can provide surgeons with additional data for personalized treatment.

While laser eye surgery complications are rare, potential risks exist for certain individuals. Panama City residents considering corrective eye surgery should discuss all applications and potential complications with their eye doctor and surgeon to determine the best procedure for their specific vision needs.
