Millions of people suffering from eye common vision problems such as astigmatism, farsightedness, and nearsightedness have been transformed by LASIK Vision Correction to lead more productive lives without the hassles of glasses and contact lenses. The excimer laser as well as the femtosecond lasers are both used during the LASIK procedure to reshape the corneal curvature.
First a microscopically thin layer of cornea is folded back utilizing a femtosecond laser, i.e. Intralase iFS 150 laser. Secondly, an excimer laser is utilized to reshape the corneal surface, thus correcting the refractive state of the eye. Finally, the LASIK procedure involves repositioning the flap layer for protection and speedy recovery. Following the procedure, typically improved vision is achieved immediately, which continues to improve in quality over the next several hours. In most cases, patients are able to return to work and resume their normal activities by the next day. Some patients may face minor visual fluctuations, especially during initial days up to two weeks following LASIK, depending on the eyeglass prescription and the individual healing rate. It is also common, during the recovery window, for some patients to feel sensation of dryness in the eyes, which is typically treated with tear drops.
During every single LASIK procedure anaesthesia is administered using eye drops to numb the eyes. The procedure does not require needles or stitches of any kind, and typically takes 10 to 15 minutes to complete.
LASEK, a LASIK variant, is performed when the corneal thickness to eyeglass prescription ratio favors a "no-flap" procedure. Both procedures utilize the same cool excimer laser beam. With LASEK, besides some discomfort during first 24 to 48 hours, the recovery period will also be several days longer. The end results are supposed to be the same with either procedure.
Patients requiring a more individualized correction are treated with CUSTOM LASIK, which captures a "fingerprint" of the eye with a 25 times more precise Bausch & Lomb's Zyoptix or VISX Wavescan/Star S4 laser system. The Wavefront technology is capable of capturing specific vision imperfections over and above nearsightedness, farsightedness, and astigmatism. An individualized treatment using a CustomVue procedure is thus available based on the data to achieve much better vision compared to glasses or contacts.
NO-BLADE LASIK – The unique Intralase iFS 150 femtosecond laser, is an all-laser, fully computerized approach to flap creation. It does not use a surgical blade for flap creation. The computer software provides utmost precision and comfort in aligning the laser pulses to create the LASIK flap in a pre-determined plane and thickness, thereby reducing patient’s anxiety, providing an unparalleled safety, accuracy, and ruling out blade-related complications.
CUSTOM-INTRALASIK combines the benefits of both technologies, potentially delivering the most advanced vision correction in select candidates.
