Pre-Operative Evaluations

Our complementary pre-operative evaluation is one of the most complete in the industry. Each potential candidate for LASIK receives a comprehensive eye exam, including multiple automated tests, thorough refractions (the measurement of the prescription of the eye), and a complete ocular health examination. Approximately 5% of the patients we evaluate are not good candidates for LASIK based on the results of their pre-operative tests.

Corneal Topography: An individualized contour map of the front surface of the cornea.

Oculus PentacamOculus Pentacam: Anterior Segment Tomography – This is the latest technology in visualizing the front and back surfaces of the cornea. It takes a photo of the ocular anatomy with a camera that images the eye 360 degrees to capture an image of all the anterior ocular structures. This allows us to rule out any mild irregularities that would preclude a patient from undergoing LASIK.

Pachymetry: The pachymetry reading is the measurement of the thickness of the cornea. We utilize two pachymetry measurements in our pre-operative evaluations: Orbscan (as illustrated above) and Konan non-contact optical pachymetry, as seen below.

Pupilometry: We use the Colvard Pupilometer, an instrument that uses infrared light to measure the pupil size in extreme dark conditions. Pupil size is an important factor in determining a patient’s risk of night time difficulties after LASIK.

Slit Lamp Examination: Doctors will thoroughly examine the cornea and other structures of the eye to rule out any diseases that would be contraindicated in LASIK.

Optical Coherence Tomography: This latest advancement in ophthalmic technology provides extremely high resolution imaging of ocular structures, allowing our doctors to more precisely evaluate the cornea, optic nerve, and retina to rule out underlying diseases.

Referring Doctors: We work with many local eyecare providers to provide our patients with the most comprehensive eye care possible.
