Types of Eye Surgery
Which Type of Eye Surgery is Best?
The type of surgery depends on your individual eyes and differs from person to person. Dr. Crews is an expert LASIK eye surgeon and has been helping people in Vancouver, Washington; and Portland & Central Oregon choose the best technology for their specific needs for over 20 years.
LASIK, or Laser-Assisted In-Situ Keratomileusis, is an FDA-approved refractive procedure that is performed on nearly 1 million patients each year. LASIK surgery corrects nearsightedness (myopia), farsightedness (hyperopia), and astigmatism by permanently changing the shape of the cornea, increasing focusing power and improving vision. LASIK surgery is one of the most common vision correction procedures. It is designed to reduce your dependency on glasses and contact lenses.
Wavescan technology captures unique imperfections in each individuals vision that could not have been measured before. This new level of measurement provides 25 times more precision than measurements using standard methods for glasses and contact lenses. Wavescan technology produces a detailed map of the eye much like a fingerprint, no two are alike. Your treatment information is then transferred to the Visx Star S4 laser providing a new level of precision and accuracy.
PRK (Photo Refractive Keratectomy)
PRK is a refractive eye surgery similar to LASIK in that both procedures are performed using the Excimer laser and is used to treat myopia (nearsightedness), hyperopia (farsightedness), or astigmatism. PRK does not involve creation of a corneal flap utilizing the microkeratome, instead, Dr. Crews will gently remove the surface corneal cells (epithelium) and proceed with the laser aspect of the procedure.
