LASIK (laser in-situ keratomileusis) is the most popular refractive surgery performed today. LASIK surgery is easy, effective and surprisingly quick. LASIK allows more freedom, making it a popular decision for those who are tired of the hassle of glasses and contacts. There are different types of LASIK surgery, which are offered at Laser & Corneal Surgery Associates in New York City and White Plains.
LASIK is a surgery that reshapes the cornea so that light is properly reflected onto the retina. This procedure reduces blurriness of vision, often making glasses and contacts unnecessary. This surgery is highly customizable, and is great for patients who are nearsighted, farsighted, or have astigmatism.
At Laser & Corneal Surgery Associates in New York and White Plains, we offer Wavefront Technology, which adds a component of better accuracy during surgery.
With Custom LASIK, LASIK surgeons are able to focus on the quantity as well as the quality of your vision. Many patients who have had Custom LASIK are reporting the ability to see clearer than ever before. Custom LASIK uses a Wavefront Analyzer to measure the way light travels through your eye. The Wavefront Analyzer creates a customized 3-D map of your eye that looks at your entire optical system. This map provides information about the unique visual characteristics of your eye which adds an additional level of data about your vision, enabling your LASIK surgeon to further customize your vision correction. This map that is created is then used to guide the laser during your LASIK laser vision correction procedure for optimal results.
What is Custom LASIK?
How is Custom LASIK different?
Standard LASIK is generally based off of your eyeglass prescription, while custom LASIK is based off of Wavefront analysis. Wavefront analysis measures not only the eyeglass prescription in a highly accurate fashion, it also maps the irregularities of the entire visual system.
What are the advantages?
Wavefront-driven LASIK allows your surgeon to further customize your surgery, providing you with:
- A greater chance of having 20/20 vision
- The potential for better vision than is possible with contacts or glasses
- Less incidence of glare and halos
Better Quality Vision
Clinical studies have shown that Custom LASIK may improve not only what you see but also how well you see it. In the past, all vision was measured using a standard vision chart. If you could see the letters, the eye doctor would use that measurement for how well you could see. Several types of visual imperfections, referred to as lower- and higher-order aberrations, exist within the eye and may affect your vision (the amount of these aberrations vary from person to person).
Previously, only lower-order aberrations (such as nearsightedness, farsightedness and astigmatism) could be measured and treated. Higher-order aberrations may also have a significant impact on vision and have been linked to glare and halos.
Now Custom LASIK may help to further customize your treatment of these higher-order aberrations that, in the past, could not be adequately treated with glasses, contacts or conventional LASIK treatments.
If you want the best possible Laser Vision Correction, then a blade-free procedure is the ultimate choice. In the LASIK and CustomLASIK procedures, a flap of corneal tissue must be created and then folded back. Standard LASIK surgery requires cutting a flap on your cornea using a sharp blade. However, it simply can’t compare to the precision and accuracy of a laser. Bladeless LASIK technology allows your surgeon to customize the corneal flap for every individual patient. And because we have access to the latest technology in flap creation, we can now treat some patients with LASIK who were previously dismissed as candidates.
- Now, you can have an all-laser procedure that is designed to deliver:
- The potential for a lower incidence of dry eyes
- Great precision and accuracy
- Great flexibility and treatment options for a wider variety of patients
- Excellent outcomes
- Technology that has been used in over a million LASIK procedures worldwide
What can I expect on the day of surgery?
Before you can undergo LASIK surgery, your doctor must examine your eyes to determine whether or not you are a candidate for LASIK. If it is determined to be a good fit for you, you will be scheduled for LASIK surgery. Upon arrival, your doctor will use a corneal topography machine (Wavefront for custom LASIK) to map out the irregularities of your eye. This gives your surgeon a clear idea of where your irregularities are, and what changes need to be made.
Once the LASIK surgery begins, your doctor will administer some topical anesthesia, and a mild sedative. Your surgeon will create a corneal “flap” using an excimer laser, exposing the interior surface of the cornea. Another laser is then used to reshape the cornea so that light is properly passed through to the retina, helping reduce blurry vision. The corneal flap is then replaced, acting as a natural bandage.
Generally, patients are allowed to leave the office around an hour after surgery. Your doctor will prescribe you anti-inflammatory and antibiotic eye drops, which you will use for around a week.
You will be asked to wear a protective eye shield at night to prevent unconscious rubbing of the eyes. Your doctor will further advise you on how to care for your eyes post-surgery. Usually, a full recovery will be made within a few weeks.
