IOL power calculation and cataract toric surgery

A few questions to Noel Alpins, Australian cataract and refractive surgeon, who is one of the most renowned expert and has deeply studied the technological aspects related to the planning of surgical procedures for astigmatism correction and its postoperative outcomes.

He has invented new methods for treating and analyzing astigmatism, and has developed the ASSORT surgical planning outcomes analysis software program that is used by ophthalmologists in Australia and overseas.

You have developed a widely used IOL power calculator, could you please explain its main advantages?
The ASSORT® software I developed is based on the Alpins Method of planning and astigmatism analysis used in refractive, corneal and cataract surgery.
The Alpins Method forms the basis for astigmatism analysis methodology published by the American National Standards Institute and is the standard adopted by the Journals of Refractive Surgery and Ophthalmology by AAO for analyzing and reporting astigmatism results.
The ASSORT® toric calculator is considered the most precise and performing IOL power calculator, thanks to its powerful algorithm based on vector analytic approach to astigmatism analysis.
The ASSORT® toric IOL calculator includes “Pre-operative planning” as well as ‘Refractive surprise analysis’ module, to manage unexpected post-op refractive outcomes.

The Assort calculator is now available in a customized version, could you tell us something more about this news?
This is the outcome of a new partnership with the Italian company SIFI and will be another important opportunity to extend the use of the Alpins Method for planning of toric IOLs and astigmatism analysis.
The SIFI ASSORT Toric IOL Calculator is now available for the Mini Toric Ready SIFI IOL at www.minitoriccalculator.com.
This new IOL of MINI line was specifically developed for the surgical treatment of astigmatism in cataract surgery.
