What is it for?

Measuring the optical imperfections of your eye that are not correctable with glasses alone (the higher order aberrations in your visual system).

When is this done?

Initial screening and during post-operative appointments.

What actually happens?

You will rest your chin on a padded support and stare straight into the examining instrument. The clinician sits in front of you and shines a bright light into your eye to help align the instrument properly. They will ask you to open your eyes widely. They will then take one or more readings of the wavefront of each eye.

How does it feel?

You feel nothing as the instrument does not make contact with your eye.

What does it do?

A wavefront analyser or aberrometer allows the surgeon to evaluate your suitability for Wavefront guided treatment as well as for detecting certain eye conditions that would preclude you from getting an optimal result.

How does it benefit you?

Allows your surgeon to decide if a Wavefront Guided treatment would benefit you more than a standard treatment. (See Wavefront Guided Treatment below).

The quality of commercial Wavefront sensors varies tremendously; like digital cameras, the best aberrometers have ten times the resolution (like camera megapixels) than the lowest quality units.
