Types of LASIK
LASIK is the most popular and common laser vision correction surgery. In most cases, LASIK can fully correct nearsightedness, farsightedness and astigmatism, and greatly reduce or even eliminate the need for prescription glasses or contact lenses.
There are several types of LASIK surgery, depending on the eye condition and technology used for the procedure. They include:
• Wavefront Optimized® LASIK Uses the detailed measurements of the curvature of your cornea. This is done to preserve the natural aspheric shape of the front surface of the eye, thereby reducing spherical aberrations that can occur with other types of laser refractive surgery.
• Wavefront-Guided LASIK Uses detailed measurements of how light waves travel through your eye to create a laser treatment that is completely personalized for your eye anatomy and vision needs. In addition to correcting nearsightedness, farsightedness and astigmatism, Wavefront-guided LASIK also can reduce refractive errors called higher-order aberrations.
• Topography-Guided LASIK Uses detailed maps of the corneal surface to program the laser to address vision problems caused by corneal scars and other abnormalities of the shape of the eye's front surface.

• All-Laser LASIK A femtosecond laser is used to create the corneal flap, eliminating the need for a bladed surgical instrument to touch the eye.
During your pre-operative exam and consultation, your eye doctor will determine which type of LASIK is best suited to your physiology and needs.
