LASIK Alternatives -PRK


Photorefractive Keratectomy (PRK)

LASIK AlternativesPRK is a procedure where the outer membrane of the cornea is removed by an instrument. Then the Excimer laser is used to flatten the top surface of the cornea, 0.2 microns at a time (less than the thickness of a human hair). This flattens the curvature of the cornea, allowing images to be more sharply focused on the retina. The laser part of the surgery takes less than two minutes.

Following the surgery, a special contact lens is applied and worn for three days. It takes approximately three days for the eye surface membrane to heal and a few weeks to months for vision to fully improve to its best level. PRK is beneficial for patients with thin corneas.

The Staar Visian ICL™

VisianICLThe Staar ICL™ is placed inside the eye surgically without laser removal of corneal tissue or removal of the natural lens. By not removing the natural lens, the eye can still focus from far to near without the need for reading glasses or a reading contact lens.

The Staar Visian ICL™ is indicated for the correction of nearsightedness (-3.00 to -20.00 D) and farsightedness or hyperopia (+3.00 to +20.00 D). It is anchored in front of the crystalline lens behind the pupil of the eye, and functions much like a traditional contact lens except that it is left indefinitely and cannot be seen or felt by the patient. Surgical results are effective immediately, with only a short recovery period.

Frequently Asked Questions:

Q: Is the Staar ICL™ permanent?
A: The Staar ICL™ is designed to be permanent inside the eye. However, unlike laser procedures which permanently remove tissue from the eye, the Staar ICL™ is removeable and replaceable.

Q: Are both eyes implanted with Staar ICLs™ at the same time?
A: Not usually. The eyes are usually implanted 1-2 weeks apart.

Q: Can the Staar ICL™ correct all degrees of nearsightedness and farsightedness?
A: Once FDA approved, the Staar ICL™ will be able to correct nearsightedness from -3.00 to -20.00 and farsightedness +3.0 to +20.

Q: Can the Staar ICL™ focus both far and near?
A: No. The Staar ICL™ does not focus far and near, the natural crystalline lens provides the ability to focus far and near for most people under age 45.

Q: Are there risks of complications associated with Staar ICLs™?
A: As with any surgical procedure, there are risks of complications. The Staar ICL™ is placed inside the eye behind the iris (colored part of the eye) and in front of the eye’s focusing lens. An occasional patient (less than 3%) may develop a cataract. Although most of these cataracts are not progressive requiring surgery, a rare patient may require removal of the Staar ICL™, removal of the cataract, and implantation of a new lens to clear and correct the vision.

Q: Can I have an Staar ICL™ if I’ve had LASIK?
A: Yes, and vice versa. A LASIK patient who did not receive full vision correction from the laser procedure can have certain degrees of residual or recurrent refractive errors corrected by implantation of a Staar ICL™. Alternatively, a Staar ICL™ patient who has a residual refractive error can have LASIK to “fine tune” the vision.
