What Is Custom LASIK?
Benefits of Custom LASIK
Custom LASIK Procedure
During the custom LASIK procedure, a wavefront device transmits a ray of light into your eye that is received and arranged into a unique pattern to create a 3-D map of your eye, including both lower and higher order aberrations. This information is transferred to the laser and applied to your eye’s position, allowing the doctor to achieve customized vision correction for each patient.

What Is Monovision LASIK?
Benefit Of Monovision Lasik Surgery
The ability to focus our eyes on objects at different distances, also known as accommodation, changes as we age. The lenses of our eyes lose their flexibility and begin to harden as a part of the natural aging process called presbyopia, making accommodation more difficult to achieve. People with symptoms of presbyopia often need bifocals or two different pairs of glasses; one for distance and the other for near vision. Patients who undergo conventional LASIK may still need glasses to correct for presbyopia after the procedure, because LASIK does not treat presbyopia — LASIK reshapes the cornea which does not affect the lens.With conventional LASIK, both eyes are corrected for distance vision, leaving some patients in need of glasses for reading and other daily activities that require near vision. Monovision LASIK preserves near and distance vision without this need for corrective eyewear. The LASIK procedure optimizes one eye for distance sight and the other eye for near sight. With practice, patients are able to adjust their vision to accommodate between distances.

What Is Photorefractive Keratectomy (PRK)?
Photorefractive keratectomy, or PRK, is a laser vision correction procedure that reshapes the cornea to correct mild to moderate conditions of:
- Nearsightedness, or myopia
- Farsightedness, or hyperopia
PRK uses an excimer laser to remove a small amount of the anterior portion, or front, of the cornea to correct refractive errors. Unlike the LASIK procedure, where a flap is created to access the cornea, PRK removes the epithelial, or outer layer, of the cornea so that it can be reshaped with an excimer laser to remove tissue from the surface. This process flattens the cornea and achieves the corneal steepening needed for vision correction.
