Safe surgical outcomes start with the quality of your diagnostic data

We feature an advanced diagnostic infrastructure

Laser vision correction is a science-based approach to quantifying your vision error (i.e., prescription) and other corneal characteristics (e.g., your corneal composition) for two primary purposes:

  • To determine if you medically qualify for treatment and, if so, for what type of procedure
  • As a basis to formulate your treatment plan

Poor quality data measurements can lead to poor decision-making which, in turn, can have serious consequences for both medical safety and surgical accuracy, so it’s essential your surgeon has access to high-quality diagnostic data.

That’s why Dr. Hyver employs an advanced data acquisition environment, featuring the Optovue Avanti optical coherence tomographer, the Oculus Pentacam corneal topographer, the Nidek Magellan and E300 topographers, and the Alcon Vario topographer. Not all practices can afford such an extensive diagnostic infrastructure, or the cost of maintaining it, but we consider it essential for safely evaluating medical candidacy and for optimizing surgical results.

The Optovue Avanti Optical Coherence Tomographer (OCT)

The Optovue Avanti Optical Coherence Tomographer (OCT)

Optical Coherence Tomography is a noninvasive imaging technique that produces high-resolution, cross-sectional images of the cornea on the micron scale. Similar in operation to ultrasound, OCT employs light rather than sound resulting in images that are much clearer and shaper. Dr. Hyver employs the Optovue Avanti OCT to evaluate the compositional layers of the patient’s cornea (pictured) as part of the pre-operative evaluation process.

The Oculus Pentacam Corneal Topographer

The Oculus Pentacam Corneal Topographer

Within a matter of seconds, the Oculus Pentacam corneal topographer produces precise imaging of the entire anterior eye segment (i.e., the front-most region of the eye including the cornea). By quantifying the depths of anterior and posterior corneal surfaces, the Pentacam calculates the total refractive power as well as the thickness of the cornea over its entire area. Dr. Hyver employs the Oculus Pentacam data in the pre-operative evaluation process and also as a basis for customizing the patient’s treatment plan.

The Nidek Magellan and E300 Topographers

The Nidek Magellan and E300 Topographers

The Nidek Magellan and E300 are high-resolution topographers that map corneal thickness and curvature. These topographers support a wide array of diagnostic applications in the refractive surgery field, including for pre- and post-operative evaluation of laser vision correction patients. Note that Dr. Hyver typically employs both the Oculus Pentacam and Nidek topographers at the patient’s consultation, giving him two independent sets of corneal imaging data that he can then cross-check, enabling him to arrive at a more precise understanding of the patient’s corneal geometry.

The Alcon Vario Topographer

The Alcon Vario Topographer

The Alcon Vario topographer performs topography, keratometry, and pupillometry. The Vario also generates corneal maps that support iris registration, which increases treatment precision by enabling the Alcon EX500 laser to automatically compensate for cyclotorsion (i.e., the patient’s eye rotation) by registering the laser’s position on the patient’s cornea using pre-established iris “landmarks.” The Vario also produces the topography data employed in topography-guided Contoura LASIK treatment.
