LVC – LASIK
What is LASIK?
LASIK, or Laser Assisted in-Situ Keratomileusis, uses FDA-approved technology in a procedure that is a safe and effective option for reducing or eliminating the need for glasses and/or contact lenses among adults with nearsightedness, farsightedness and astigmatism.
In LASIK, the surgeon creates a flap on the surface area of your cornea using a Femtosecond Laser. He/she then lifts the flap and folds it out of the way of the second laser. The surgeon then applies a ultraviolet “cold” laser, called an excimer laser, to the inner corneal surface correcting the vision problems by reshaping the cornea with that laser beam. By reshaping this layer, it allows the eye to focus clearly. After the laser treatment finishes, the doctor re-positions the flap.
What are the advantages of LASIK?
LASIK is an improvement over other methods of vision correction, such as RK (refractive keratectomy) or PRK (photorefractive keratectomy) surgeries. LASIK is performed under a protective layer of corneal tissue aka the ‘”flap”. As a result, there is less surface area to heal, less risk of scarring, less risk of corneal haze, less postoperative discomfort, less postoperative need for medications, and vision returns more rapidly, often within a day or so.
How is LASIK different than PRK?
LASIK and PRK both reshape the center layer of the cornea with a laser. How we get to the center layer is different between LASIK and PRK. LASIK uses a ‘flap’ to get to the treatment area, while PRK has no flap – it brushes away the out layer of the cornea called the epithelium. The final outcomes are the same with either technique, and the decision whether to do LASIK or PRK is up to the patient, unless corneal thickness is in question. LASIK has a faster recovery time, while PRK provides the benefit of no flap complications.
