Laser Vision Correction, also know as LASIK (Laser-Assisted in-Situ Keratomileusis), is laser eye surgery intended treat nearsightedness, farsightedness, and/or astigmatism and reduce the dependency on contact lenses and eye glasses. At Vista Eye, we use the latest technology for our pre-operative exams and vision correction procedures, including PRK and LASIK. All surgeries are performed by a fellowship trained laser vision correction and cornea specialist, Dr. Jani. LASIK Overview The most common type of refractive surgery, LASIK, is an all laser procedure that can restore your vision. During LASIK, the eye surgeon creates a corneal flap with a femtosecond laser (All Laser LASIK) which is then folded over, so that the eye surgeon can precisely remove tissue from the cornea. By resculpting the corneal tissue, light focuses better into the eye, resulting in clearer vision. Excimer lasers can also be used to correct astigmatism by smoothing the surface of cornea to a more normal shape. The popularity of LASIK is due to many advantages, which include: Freedom from or less dependence on glasses and contacts Recovery time of 1-2 days Actual surgery lasting 10-20 minutes Little or no discomfort Immediate results by the next day Both eyes can be treated the same day LASIK Procedure The eye surgeon will first create a corneal flap using a femtosecond laser. After folding the flap back, Dr. Jani will use an excimer laser to reshape the cornea’s curvature to the precise correction (steepened for far-sighted patients, flattened for near-sighted patients). The laser treatment typically lasts 30 seconds or less depending upon the amount of correction desired. After the cornea is resculpted, the corneal flap is put back in place, like a natural bandage. The entire procedure takes about 10 minutes per eye, and patients are often ready to leave within an hour. The eye heals on its own within a few days with no need for stitches. The outer layer of the cornea, or epithelium, is a soft, rapidly regrowing layer that regenerates within a few days with no loss of clarity. In LASIK, the epithelium is not removed as in PRK; a flap is used to uncover the deep layers of the cornea. Thus, the recovery time is faster for LASIK. The deeper layers of the cornea, as opposed to the outer epithelium, have very limited regenerative capacity. At Vista Eye Specialists, we utilize the latest technology, including Intralase and WaveLight® Technology. LASIK Recovery With LASIK surgery, most people’s vision improves right away, but some find that their vision gradually improves even more over the next few days or even weeks. The recovery time for LASIK is typically 1-2 days. Eye shields are worn after the procedure and it is imperative that the eyes are not rubbed or disturbed for the first 48 hours or the corneal flap created during the procedure could be disturbed and lead to wrinkling of the flap. The various eye drops prescribed by your eye surgeon will help the healing process, while over-the-counter pain relievers may also be helpful to relieve any discomfort. Vista Eye recommends patients have a few days of rest for recovery. While some activities, like driving and going back to work can resume after a couple of days, certain activities, such as swimming and strenuous exercise, will be limited during the weeks following surgery to avoid any trauma to the eyes. LASIK versus PRK LASIK involves creating a corneal flap and shaping the cornea, while no flap is created during PRK. Both PRK and LASIK can be done on both eyes at the same time, however, the recovery time is typically longer with PRK. For many patients, LASIK is their first choice for laser vision correction due to less recovery time and discomfort levels. However, PRK is a safe, successful alternative for patients who are not good candidates for LASIK or choose not to have a corneal flap for their laser vision correction procedure. Studies have demonstrated in the long term, PRK and LASIK are very equivalent procedures in so far as vision is concerned however the primary difference is the speed of visual recovery. Difference between LASIK and PRK Refractive Errors That LASIK Can Help You to Overcome Laser Vision Correction In Fredericksburg A refractive error is a problem that causes light to bend incorrectly to the retina, resulting in blurry vision. LASIK or PRK is effective at treating the three most common types of refractive errors:
