Welcome to the ASSORT Vector Planning Calculator.
This online calculator incorporates the corneal astigmatism as well as the refractive cylinder into a possible excimer laser treatment plan.
Features of the ASSORT Vector Planning calculator include:
- Calculation of the Ocular residual astigmatism (ORA – the vector difference between the corneal astigmatism and the refractive cylinder at the corneal plane expressed in diopters)
- Display of astigmatic treatment (TIA) using emphasis of
- 100% Refraction
- 60% refractive / 40% corneal parameters
- 100% Corneal
- Calculation of target refractive cylinder and target corneal astigmatism
These calculators allow astigmatism analysis of one eye only; group analyses are performed by purchasing the ASSORT or VECTrAK software
