The overwhelming majority of our patients that desire independence from glasses and contact lenses using a vision correction procedure benefit the most from either LASIK or Refractive Lens Exchange, depending upon your age. There are certain scenarios in which your doctor would recommend an alternative procedure. Dr. Rush will discuss these other less common options with you if they offer an advantage to achieve your best possible outcome.
Photorefractive Keratectomy (PRK)
uses the same excimer laser used in advanced LASIK but is done directly over the surface of the eye without the creation of a flap. We favor LASIK in most cases as PRK requires a longer healing time on the surface of the eye and has more discomfort in the postoperative period. Excellent outcomes can still be achieved using this technique, and it remains a good alternative treatment option in very select cases.
Phototherapeutic Keratectomy (PTK)
also uses the same excimer laser used in advanced LASIK but is done in a setting in which disease such as corneal scarring or keratoconus is present. PTK can correct for your refractive error while simultaneously removing scar tissue or otherwise smooth out a misshapen cornea. Oftentimes, simultaneous LASIK can be done in the fellow eye in the absence of disease. PTK can also be done in combination with advanced corneal collagen cross-linking procedures.
Small Incision Lenticule Extraction (SMILE)
is a laser correction treatment using a femtosecond laser to carve out a small portion of the corneal tissue to correct nearsightedness. It has limited ability to correct high amounts of refractive error and astigmatism.
Implantable Collamer Lens (ICL)
is a type of lens implant that is placed internal to eye to correct for refractive error. It has the advantage of being able to correct extremely high amounts of nearsightedness. It is unable to correct significant farsightedness and astigmatism.
