The Different Types of Laser Eye Surgery
When people think of laser eye surgery, LASIK often comes to mind. While LASIK is prevalent, other effective laser procedures address conditions like myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. In fact, there are four main types: PRK, LASIK, Customized LASIK, and LASEK.
PRK (Photorefractive Keratectomy)
PRK involves using a cool laser beam, known as an excimer laser, to remove excess corneal tissue. This reshaping helps light focus properly on the retina. The procedure removes the outer layer, or epithelium, revealing the cornea for treatment. Unlike LASIK, PRK doesn't involve creating a corneal flap. Instead, the epithelium heals naturally. Patients wear a protective contact lens for a few days to minimize discomfort.
LASIK (Laser Assisted In-Situ Keratomileusis)
LASIK is a popular choice in the U.S. It involves creating a flap in the cornea using either a microkeratome or IntraLase. The excimer laser then reshapes the cornea to fix refractive errors. After reshaping, the flap is repositioned and acts as a natural bandage, speeding up the healing process and reducing discomfort.
Customized LASIK
This advanced version of LASIK uses wavefront technology to map the eye's unique surface. A light beam measures optical distortions as it exits the eye, allowing for precise correction of irregularities. This technology is especially beneficial for treating higher-order aberrations, reducing issues like halos and glare, ultimately improving visual clarity.
LASEK (Laser Assisted Sub-Epithelial Keratectomy)
LASEK is ideal for patients with thin or flat corneas who might not qualify for LASIK. A small blade cuts into the epithelium, and a mild alcohol solution softens its edges. The surgeon then adjusts the flap, exposing the cornea for reshaping with an excimer laser. Replacing the flap speeds healing and reduces discomfort.
Conclusion
While PRK, LASIK, Customized LASIK, and LASEK all aim to correct refractive errors, each method has unique benefits and suitability for different patients. Those considering laser eye surgery should consult their ophthalmologist to explore options and determine the best procedure for their needs.
