Lawrence Eye Care is now offering LASIK laser vision corrective surgery! Call now for a free evaluation!
LASIK surgery is a procedure that corrects abnormalities in the eye to improve your vision. LASIK can correct conditions such as nearsightedness, farsightedness and astigmatism. With LASIK surgery, many of our patients walk away with 20/20 vision and all of the conveniences that come along with better sight. Never worry about forgetting your glasses or needing to maintain proper hygiene with your contact lenses again. At Lawrence Eye Care, we are happy to be able to give you back control of your sight.
LASIK surgery is one of the safest and most comfortable procedures you can undergo. Due to this, and its high success rate, LASIK is the most common procedure used to correct vision. In refractive surgeries, the laser reshapes the surface of your eye, improving the cornea so that light is properly focused on the retina. This allows you to see without using glasses or contact lenses. Each eye is done separately, and the procedure takes around five minutes for each eye. You will be asked to look directly into the laser for the length of the procedure, but it will be entirely painless; you may only feel some mild pressure on the eye. You can expect hazy and blurry vision immediately after receiving LASIK, but your vision will begin to improve almost immediately. LASIK in itself is a simple procedure, and it has a simple recovery to match. In most cases vision is corrected in only a couple days after surgery, and the recovery is very simple; we recommend that you rest as much as possible to allow the eye to heal quickly, but you will be able to return to your routine a day or two after having the procedure done. This simple procedure can have an enormous impact on your life. Consider LASIK surgery at Lawrence Eye Care as a means to correct your vision and improve the way you see the world.
PHOTOREFRACTIVE KERATACTOMY or PRK
PRK, which stands for Photorefractive Keratectomy, is a laser correction surgery very similar to LASIK that is more beneficial for those who have very thin corneas.
While traditional LASIK cuts a flap into the cornea, the PRK procedure simply removes only the outermost layer of the cornea (called the epithelium) before using the same excimer laser used in LASIK to sculpt the cornea and correct refractive error. Altering the shape of the cornea allows light entering the eye to be properly focused on the retina for clear vision. While both procedures will result in corrected vision, some prefer LASIK for the faster healing times and others prefer PRK for its extra safety as the original laser surgery for vision correction. PRK is a safer procedure for patients with thin corneas since more of the cornea is left untouched during the procedure than in LASIK. Unlike LASIK surgery, there is no risk of corneal flap complications because the cornea does not need to be cut. Like most other refractive surgeries this procedure only takes 5 minutes per eye, and most people only feel a little pressure. You will be awake during the procedure but your eyes will be numbed with a topical anesthetic. Your surgeon will have you look into a target light while the laser uses pulses of light to reshape your cornea. As an additional benefit, patients experience less dryness in the eyes following PRK surgery. However, PRK does have a slightly longer recovery time than LASIK surgery as the outer layer of the cornea has to repair itself. After the procedure, you will have a corneal abrasion that will take 3-5 days to heal. The body is an amazing thing, and the cornea is able to repair itself without sutures or much interference from your surgeon. During the healing time you will wear a soft contact lens that acts as a bandage to minimize pain, promote healing, and protect the cornea. After the cornea has healed, your surgeon will remove this bandage lens for you. As a PRK patient, you will likely experience mild discomfort during the healing process. Expect some blurry vision initially; it is very normal for several weeks to pass before vision is clear and stable! Your vision will continue to improve and you will achieve excellent sight and minimal disruption to the cornea with PRK laser correction surgery.
Eye Surgery Evolution
Advanced technology has made it possible to reshape eyes and restore vision to healthy levels for many people from all walks of life. Surgical techniques and tools have rapidly evolved over the past two decades to create procedures that are both safe and helpful.
Corrective surgeries for eyes now include everything from using lasers to reshape the cornea surface to inserting artificial lenses. These procedures correct how light entering the eye is processed – leading to much sharper vision in patients.
The state of the cornea is a determining factor in these surgeries. Thinner corneas with a high degree of myopia, for example, usually require a more invasive surgery to reshape the eye surface enough to improve vision.
Types of Eye Surgeries
Laser correction surgeries offer a snapshot of evolution in eye surgeries. Photorefractive Keratectomy (PRK) became the first successful surgery to change the shape of the cornea through removing tissue. The FDA approved PRK in 1995 and it is still widely used early in the 21st Century. With PRK, it only takes a few days for vision improvements to be realized.
LASIK followed on the heels of PRK. It involves cutting a thin flap in the outer covering of the eye to reshape the cornea. Unlike PRK, it only takes a few hours to gain sharper vision with LASIK surgery. There is some risk of suffering dry eye and other complications such as halos around bright lights until the flap fully heals. At Lawrence Eye Care we will be preforming LASIK with a femtosecond laser for flap creation and an excimer laser for reshaping the cornea with customized wavefront technology that measures how light hits the eye.
Some eye surgeries require implanting new artificial lenses to produce vision improvements. Implantable lenses similar to contact lenses can correct more severe levels of nearsightedness. These artificial lenses go permanently over the natural lens on the eye. Refractive Lens Exchange (RLE) takes it a step further and replaces the natural lens with an artificial lens of a different shape. RLE is done to correct extreme farsightedness.
Eye Surgery Considerations
Our eyes change as we age, so some corrective surgeries are not a good option for everyone. People under 18, for example, are not good candidates for laser eye surgeries because their eyes change rapidly as their bodies are growing.
Health also factors into eye surgeries. If you have diabetes or other medical conditions that impact eyesight, certain eye surgeries may pose serious risks.
