Introduction to LASIK:
Since the late 1970's, incisional refractive surgery (RK) has treated nearsightedness and astigmatism in patients all over the world, allowing them to experience a new kind of freedom. It is the kind of freedom that allows people to make lifestyle choices that were not options to them before because they were totally dependent on glasses or contact lenses. Now, refractive surgery is experiencing the dawning of a new era with the advent of the excimer laser, with the FDA approval of photorefractive keratectomy (PRK) in 1995 and now Laser Assisted in-Situ Keratomileusis, or LASIK in 1999, which represents another important step towards reducing dependence on corrective lenses. Now, All Laser Wavefront LASIK is another exciting step toward quality vision while minimizing side effects.
LASIK combines the precision of the excimer laser delivery system with the benefits of Lamellar Keratoplasty (LK) to treat a wide range of refractive errors. Advantages of the LASIK procedure have resulted in rapidly growing popularity of this operation among refractive surgeons all over the world.
The LASIK procedure combines two sophisticated techniques to correct nearsightedness, farsightedness and/or astigmatism. The first technique involves the use of the Intralase Laser to create a thin protective layer of corneal tissue (flap) that covers the area to be sculpted by the laser. This flap allows for rapid recovery of vision and reduces discomfort after the procedure. The second technique uses the excimer laser to sculpt the underlying cornea, correcting the refractive error. The protective layer of tissue (the flap) is repositioned without sutures. The eye is not patched, but a protective shield is placed over the eye to prevent inadvertent rubbing of the eye. Visual recovery is typically rapid and there is little or no post-operative pain. Eye drops, including an antibiotic to guard against infection, are taken for less than one week.
