The VECTrAK program

VECTrAK by ASSORT is a comprehensive yet simple-to-use astigmatic vector calculator, developed for ophthalmic surgeons. VECTrAK can determine astigmatic changes occurring following cataract, astigmatic keratotomy and laser surgical procedures.

The Alpins method is a key feature of VECTrAK showing calculations for:

• TIA, SIA and Difference Vector
• The Correction Index
• Coefficient of Adjustment for nomogram refinement of systematic over- and undercorrection
• The success as measured by the Index of Success
• Angle and Magnitude of Error
• Other useful parameters

With minimal data entry, information about the effective change in astigmatism is rapidly calculated for up to 500 patients. VECTrAK allows these patients' data to be stored as well as having a data file import/export function for file formats such as Dbase, ASCII delimited, and Paradox formats.

VECTrAK - Up to 100 patients: US$595.00

VECTrAK - Up to 500 patients: US$895.00

VECTrAK - Up to 500 patients with import/export function: US$1595.00
