We’re proud to offer Blade-Free LASIK as part of our ongoing commitment to patients who want the latest advances, the best vision, and the highest quality of life.
Custom LASIK uses wavefront technology to generate a 3-D map of your cornea for the surgeon to evaluate. The wavefront analyzer used makes the procedure as much as 25 times more precise than conventional LASIK. Treating a patient with the information taken from the wavefront analyzer can result in greater clarity of vision and fewer complaints of glare and night halos.
Blade-free LASIK is one of the most trusted laser procedures available. The LASIK surgeon uses a computer guided laser during the first step to create a micro-thin corneal flap. The laser moves back and forth across your eye, a uniform layer of tiny microscopic bubbles forms just below the corneal surface. The flap is created as the surgeon gently separates the tissue where the bubbles have formed. The corneal flap is then lifted to expose the inner cornea for the next step, performing the laser procedure that will correct your vision. Finally, when the procedure is completed, the flap is positioned in place and the healing begins.
HISTORY OF PRK
Laser vision correction is a term used for Photorefractive Keratectomy (PRK) and Laser In Situ Keratomileusis (LASIK). PRK was actually invented first, but LASIK gained more popularity because patients experience less discomfort and obtain good vision more quickly. Although vision improvement with PRK is gradual over a few weeks or months, this procedure is many surgeons’ preferred treatment for patients not suited for LASIK—specifically those with thin corneas.
Both nearsighted and farsighted people can benefit from PRK. With nearsightedness, the goal of treatment is to flatten the cornea. With farsightedness, the desire is to create a steeper cornea. PRK can also correct astigmatism by smoothing an irregular shaped cornea into a more normal sphere. When the cornea is reshaped in the right way, it works better to focus light into the eye and provide clear vision.
HOW SURGERY WORKS
PRK is performed with the same highly sophisticated excimer laser our surgeons use for LASIK. Using a cool beam of ultraviolet light it reshapes the cornea by precisely removing microscopic amounts of tissue.
However, unlike LASIK where a thin flap is created and folded back to expose underlying tissue, with PRK the surgeon gently brushes aside a protective layer of surface cells covering the tissue to be treated. Anesthetic drops are placed on the eye so there is very little if any discomfort during the procedure.
Once the protective layer of cells is brushed aside from the surface of the cornea, the laser is guided to reshape the underlying tissue in a procedure that usually takes less than a minute. A protective contact lens is then placed over the treated area, which allows the surface cells to regenerate and heal during the next 3 or 4 days. In addition to helping the healing process, the contact lens reduces most of the discomfort associated with recovery.
