Corneal tomography and imaging uses:
- Pre-LASIK and Trans Epithelial PRK biometry
- Early detection of Keratoconus
- Evaluation of corneal scars
- Post-LASIK and Trans Epithelial PRK biometry
The Corneal Imaging mode uses an arc radius of 8-9 mm to match the cornea’s radius of curvature. The scan area can image the entire cornea utilizing four equally spaced meridians. The Insight 100’s ability to take precise corneal tomography and micro-measurements in the cornea and anterior segment provides early detection of subtle keratoconus eye disease, allowing the patient to receive the best care.
Corneal Ultrasound Solution
The ability to image the entire anterior segment in minute detail provides deeper insights into the actual anatomical structure of the cornea before and after refractive surgery.
Studies have shown that having this data available may enable clinicians to increase their LASIK and Trans Epithelial PRK candidacy and avoid ruling out patients from LASIK and Epithelial PRK surgery due to suspicious front and back surface corneal tomography 1,2.
IQ Laser Vision states that “We are able to achieve a very precise image of your eye that provides an accurate assessment of the type of vision correction that will be the best prescription for your personal eye care.” Read more from IQ Laser Vision here.
The epithelial thickness mapping that the ArcScan Insight® 100 System covers the entire 10mm diameter of the cornea, making it a viable instrument in analyzing and diagnosing potential underlying pathologies. The system’s integrated continuous scan mode allows clinicians to focus the scan easily on specific areas of interest to generate more precise corneal tomography and imaging. Furthermore, a deeper understanding of the various corneal layers may assist in evaluating potential Keratoconus and other physical corneal aberrations.
