Types of Laser Eye Surgery
We provide various types of laser eye surgery through our iLASIK Technology Suite, which is a combination of IntraLase (a femtosecond custom flap laser) and Advanced CustomVue Technologies (a custom prescription laser).
Laser surgeries correct common refractive errors:
- Nearsightedness (myopia) – A person can see things clearly near, but not far.
- Farsightedness (hyperopia) – A person can see things clearly far away, but not near.
- Astigmatism – This is a common imperfection in the eye's shape, where the eyeball is a bit lopsided rather than normally round. Depending upon where things are in ones’ vision, they may become distorted and wavy.
- Presbyopia – This is something that happens to many people over the age of 40. The lens of the eye becomes less flexible. This is when people start buying reading glasses.
Laser surgeries correct refractive errors. If a patient’s eyesight falls within certain normal ranges, one procedure, LASIK or PRK may be used. If a patient’s eye refraction errors are outside those ranges, additional customization using more advanced techniques (LASEK) must be utilized.
We utilized the most advanced Custom Wavefront Procedures, which first create three-dimensional images of the eye. That information is used to guide the entire laser eye surgery procedure.
Both PRK and LASEK laser procedures are done with the iLASIK technology suite, so it does not involve a different set of lasers. Rather, the different procedures use the lasers in different ways, optimizing the procedures to best fit each patient’s needs.
Photorefractive keratectomy (PRK) corrects refractive errors. This works by completely removing the top layer of the cornea, known as the epithelium. Lasers are then used to reshape the cornea. Because the epithelium had been removed, a contact-like bandage is put on the eye until a new epithelium layer grows back in about five days. Complete healing may take up to a month.
Laser-assisted in-situ keratomileuses (LASIK) also reshapes the cornea. However, it creates a flap in the epithelium, rather than removing it completely. After using a laser to reshape the lower layers of the cornea, the epithelium flap is put back over the cornea. This procedure may give you almost instant great vision.
Laser epithelial keratomileusis (LASEK) also reshapes the cornea. This procedure combines certain methods from both PRK and LASIK procedures. It works best with those with thin corneas or with large pupils. Healing time may take longer than PRK.
