Excimer Laser Keratectomies, also known as refractive surgeries or laser eye surgeries, are a type of surgical procedure performed to correct vision problems like nearsightedness, farsightedness, and astigmatism. It utilizes a specialized laser called an excimer laser to reshape the cornea, which is the transparent front part of the eye, in order to improve the eye's ability to focus light.
During an Excimer Laser Keratectomy, the patient's eye is numbed using anesthetic eye drops. Then, a thin protective flap is created on the cornea using a microkeratome or a femtosecond laser. The excimer laser is then utilized to precisely remove tiny amounts of tissue from the cornea, reshaping its curvature based on the specific vision problem being addressed. This allows light to properly focus on the retina, resulting in clearer vision.
Excimer Laser Keratectomies offer several benefits over traditional eyeglasses and contact lenses. They can provide permanent vision correction, eliminating the need for corrective lenses in many cases. Additionally, they offer a quick recovery time, with most patients experiencing improved vision within 24-48 hours after the surgery. However, it is important to note that Excimer Laser Keratectomies may not be suitable for everyone, as certain eye conditions, age, and medical history can affect eligibility for the procedure.
Overall, Excimer Laser Keratectomies are an effective and widely practiced surgical option for individuals with common vision problems, offering the possibility of long-term, glasses-free vision improvement.
