Assort is currently negotiating with makers of refractive lasers and
corneal topography machines to include Alpins' method in the programming of their equipment.

Based in Houston, Texas, Tracey Technologies has produced devices integrating ray tracing aberrometry wavefront analysis with advanced
corneal topography analysis for a decade, with the iTrace series of products offered since 2008.
Other chapters address
corneal topography and tomography; the application and validation of the registration approach; optical coherence tomography (OCT) and clinical and research applications, uses in medical or surgical treatment, and uses in the detection and monitoring of cysts; the evolution of fundus perimetry technology; applications of IVCM (in vivo confocal microscopy) in clinical settings and research; the biomechanical modeling of blood vessels; hybrid finite element simulation for bioheat transfer; the effects of electromagnetic fields on specific absorption rate and heat transfer; dry eye characterization by analyzing tear film images; and thermography.

Corneal topography provides an invaluable platform for the observation of corneal profile and ultimate choice of contact lens design.
The prevalence of true unilateral keratoconus has been reported to range from 0.5-4% in studies using computerized videokeratography (1,2) and was 4.5% in a more recent study using slit scanning
corneal topography (Orbscan 2).
This type of analysis is more comprehensive than the simple analysis of the
corneal topography as it offers the refractive behavior of a chosen area of the anterior corneal surface in a global form rather than the focal one obtained when the study is performed by the analysis of the keratometry values in given meridians.
Another study by Sonmez et al20 showed that hyperglycemia causes refractive change in cornea of diabetic patients and was detected by
corneal topography. Lee et al21 showed that patients who had diabetes for more than or equal to 10 years duration had advanced corneal morphological abnormalities.
