Laser Vision Correction
What Is LASIK Eye Surgery?
LASIK Eye Surgery is a refractive procedure that reshapes the cornea to correct nearsightedness, farsightedness and astigmatism. LASIK offers many improvements over other refractive surgery procedures. These include little or no post-operative discomfort, immediate vision improvement, and the ability to drive or return to work quickly-sometimes as soon as the next day. Most patients require no corrective eyewear after surgery although patients over 40 may require reading glasses.
Types Of LASIK Procedures
- Custom LASIK
- Monovision LASIK
- Intralase LASIK
What Is Custom LASIK?
Custom LASIK, is the standard in laser vision correction. It offers the most accurate, individualized results for each patient. This FDA-approved procedure uses three-dimensional measurements of the eye to guide the laser as it reshapes the cornea and corrects your vision.
Benefits of Custom LASIK
Custom LASIK benefits patients benefit by achieving 20/20 vision, with many patients obtaining vision that is better than 20/20, a goal that has not been achieved with traditional LASIK, glasses, or contacts. Custom LASIK also reduces the risk of poor night vision and glare, side effects that are common with traditional 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?
Monovision LASIK surgery corrects one eye for distance and the other eye for near vision, eliminating or reducing the need for patients, with presbyopia, to rely on glasses or contacts. Patients are able to retain their near and distance vision after LASIK surgery. If you are over the age of 40 and wear bifocals or reading glasses, monovision LASIK may be an option.
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 IntraLase LASIK?
The IntraLase method provides a blade-free approach to laser vision correction. IntraLase uses laser energy to create a customized flap based on the shape of the eye, providing the patient with the best possible outcome.
Benefit Of Intralase Lasik
IntraLase offers patients many benefits over the traditional LASIK procedure, including improved accuracy and customization, a shorter recovery time and a reduced risk of flap-related complications. The IntraLase technique also allows for complete customization of the LASIK procedure to accommodate each patient’s individual vision needs. All elements of surgery, including the size, location and angle of the flap, can be customized for the most precise results.
What Is 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.
