What is Custom Wavefront LASIK?

Custom Wavefront is Lasik that is done using special equipment. This equipment is capable of making precise measurements that map each eye’s defects.

This information determines the degree of error that needs to be corrected. This technology can also be used to direct the laser for precision shaping of each cornea.

How Does It Work?

Custom Wavefront Lasik is a huge improvement over early laser ablation methods. It involves two steps. First, this technology gathers customized information about the way light travels through each eye, and computerizes these measurements.

Next, the computerized data is used to guide the laser in sculpting each cornea to the most effective shape. In all-laser Lasik, the laser, rather than a knife, is used to cut the flap as well as to shape the cornea.

Your eye surgeon may use this technology for both diagnostic measurements and to guide the laser during his procedures. Even if he doesn’t use it for the Lasik procedure, find out if he uses it for diagnostic measurements.

The Wavefront Lasik procedure, otherwise, is not different than traditional Lasik surgery. Your surgeon will cut a flap of corneal tissue, which is laid back to expose the tissue that will be reshaped to correct the error in your vision.

Pros and Cons

Indicated If You:

  • have sufficient corneal tissue to do the procedure
  • between ages of 18 and 40
  • have nearsightedness, farsightedness, presbyopia or astigmatism correctible by laser eye surgery
  • no eye disease or condition that can interfere with healing
  • corneal shape within treatable range
  • normal pupil size
  • adequate tearing, moisture
  • are otherwise a qualified candidate for Lasik eye surgery
  • Wavefront LASIK is not recommended if you

  • have thin corneas
  • engage hobbies or profession that are rough or pose risk of hitting eyes
  • have dry eye
  • have had lens prescription changes within two years
  • have cataracts
  • have glaucoma
  • are pregnant or nursing (lactating)
  • have corneal scarring
  • have eye disease or abnormalities that will slow healing
  • are taking steroids or immunosuppressants
  • have eye disease or abnormalities that will slow healing such as:
  • diabetic retinopathy
  • ocular hypertension
  • autoimmune disorders
  • are taking steroids or immunosuppressants
  • Herpes simplex of the eye
  • hypertension
  • Associated Risks

    Custom Wavefront Lasik has risks that are similar to other laser eye surgery procedures. Though rare, the ones that occur most often include:

  • over- or under-corrections
  • halos or starbursts around lights
  • erosion of the epithelium
  • dry eye
  • infection
  • corneal scarring
  • eyelid droop
  • chronic discomfort
  • inability to tolerate contact lenses
  • Doing your homework can minimize risks. Find out if your eye surgeon has plenty of experience using Custom Wavefront technology for both the diagnostic procedure and the Lasik surgery procedure.
