LASIK Procedure | How will my eyes be assessed

The pathway to this treatment normally involves three health professionals. The first step is the patient’s optometrist or general practitioner delivering a referral. The patient then attends the eye surgery clinic where an orthoptist undertakes a full vision assessment, including an assessment of their current need for spectacles and/or contact lens. Finally, the patient sees an ophthalmologist.

Detailed measurements of the corneal profile are made using a corneal topographer, the Pentacam. They are taken at multiple positions on the cornea, providing very accurate information on the magnitude of front and back elevation and contour, and the thickness and power of the cornea. Once it is determined that a patient’s corneal topography is within an accepted normal range it is safe to proceed with laser vision correction.

Normal corneal topography is a pre-requisite to proceeding with laser vision correction. Very rarely, subtle irregularities are identified that prevent some patients from proceeding. In some situations corneal topography may provide important prognostic information that is not evident on the ophthalmologist’s examination or corneal topography performed using older technology.
