Vision correction has improved immensely over time from eyeglasses to contact lenses to laser vision correction procedures. The advancements in technology have allowed doctors to provide higher quality services to patients with more severe vision conditions. Simply non-invasive procedures can eliminate a person’s need for eyeglasses within a matter of minutes.
Laser vision correction can provide relief to patients suffering from nearsightedness, farsightedness, and/or astigmatism.
The absolute goal of laser vision correction is to provide patients with superior vision. In order to achieve superior vision the shape of the cornea must be altered from the current shape.
Most patients will be able to achieve 20/40 vision with one procedure which is the requirement in order to pass the driver’s vision text without being required to wear glasses when driving. The outcome of the procedure will depend on the current vision condition.
Photorefractive Keratectomy (PRK) is one of the first laser vision correction procedures. A laser is used to modify the shape of the cornea by first removing the top layer of the cornea. Once the top layer is removed the laser then begins to reshape the cornea to the appropriate shape.
The drawback to PRK is that the top layer of the cornea is removed during the surgery which can cause a longer healing time. PRK is now an alternative for patients who do not qualify for LASIK or have mild nearsightedness.
Laser Assisted In-situ Keratomileusis (LASIK) was first introduced in the late 90’s and has become a popular procedure amongst patients looking to shed their glasses and contracts. During LASIK a corneal flap is created and pulled back during surgery. Once the surgeon has created the corneal flap, a laser will be used to correct the shape of the cornea. After the shape has been changed the corneal flap is set back into position so that healing can begin. Because no tissue is removed from the cornea during the procedure the healing process is relatively quick and most patients resume their normal routines the days after surgery. If your ideal vision is not achieved after the first procedure you may have additional enhancements to improve your vision.
