Not all patients are candidates for LASIK. Some are more suited to other procedures such as PRK, Monovision, and Visian ICL. During your Free Personalized LASIK Evaluation, your surgeon will determine which procedure is most suited to your visual needs.
Monovision is a treatment technique that is often prescribed for people age 40 and older who are affected by presbyopia. Presbyopia occurs when, as part of the natural aging process, the eye's crystalline lens loses its ability to bring close objects into clear focus.
Monovision means wearing a contact lens for near vision on one eye and, if needed, a lens for distance vision on the other eye. Most people who try monovision are able to adjust to it. Alternative treatments for presbyopia include a combination of contact lenses and reading glasses, or your doctor may also prescribe bifocal contact lenses.
PRK (Photorefractive Keratectomy) has been also termed "LASIK without a flap". It is primarily offered to patients whom are poor candidates for LASIK due to corneal curvature or corneal thickness issues. PRK is equally effective as LASIK with long-term results being equal. With the PRK procedure, no flap is made on the cornea.
The outside layer of cells (epithelium) on the cornea is removed. The laser then reshapes the cornea to the desired correction in the same manner as the LASIK procedure. A soft contact lens is then placed on the cornea to function as a bandage. It remains in place 24 hours-a-day for 3 to 4 days until the epithelium heals over completely, then it is removed. It generally takes about one week for visual function to return to normal. Eye drops are used post-operatively for 12 weeks to control the healing process.
Visian ICL (also called the Implantable Collamer Lens), created by STAAR® Surgical Company, is a phakic intraocular lens (IOL) for the treatment of myopia and other refractive errors.
The Visian ICL is a great alternative to LASIK eye surgery but is typically used for patients that might have more nearsightedness than what LASIK can treat. For patients with high levels of myopia or nearsightedness this implant is a great option. So instead to treating your refractive error with a laser, this treatment works by inserting a collamer lens implant inside the eye.
