Laser Vision Correction Surgery
Laser Vision Correction Surgery consists of LASIK and PRK. This precise treatment of the cornea allows for better vision than glasses or contact lenses, while providing the freedom from those hassles. Laser Vision Correction is often cheaper than glasses and contact lenses in the long run. It has also been shown to be safer than long term contact lens wear.
LASIK (Laser-Assisted In Situ Keratomileusis) is a laser vision correction surgery that has helped millions of people achieve better vision since the 1990s. There has been over 18 million LASIK procedures done in the United States, and LASIK is one of the safest and most effective surgeries. As a testament to how safe and effective LASIK is, both Dr. Hsiao and his wife had LASIK surgery done in 2009 and can’t thank this technology enough for changing their lives!
Refractive errors (near-sightedness, far-sightedness, and astigmatism) occur when the shape of the cornea does not match well with the length of the eye. This results in blurred vision because the light does not get properly focused on the retina.
LASIK works by using a precise computer controlled laser to reshape the cornea. By reshaping the cornea, the light is properly focused on the retina, resulting in clear vision. Prior to the reshaping, a separate laser is used to create a thin flap on the cornea. This flap allows for fast visual recovery and comfortable healing.
PRK (Photorefractive Keratectomy)
PRK is a laser vision correction surgery that is able to correct near-sightness, far-sightedness, and astigmatism. PRK has been called many names, but it is basically LASIK without a flap. Instead of making a flap, the surface cells of the cornea is removed prior to reshaping the cornea. The cornea is then reshaped with a precise laser, just like in LASIK.
Benefits of PRK
- Less dry eye after surgery
- Patients who are not candidates for LASIK due to thin corneas may still qualify for PRK
- No flap means less chance of corneal damage for people involved in certain physical activities that involves possible trauma to the eye
