Abstract Details

Purpose:

The aim of the study is to evaluate various innovative properties of MINI TORIC READY (SIFI Medtech) intraocular lens (IOL). Mechanical stability guaranteed by four haptic design. Good optic performance determined by aspheric toricity, large clear toric optic zone and anti-scattering optic edge.

Setting:

Department Research and Development SIFI Medtech, Catania, Italy. Clinic DiStefano-Velona, Catania, Italy.

Methods:

IOLs mechanical stability were clinically investigated. IOLs optical performance, related to the aspheric design and extended dimension of the toric zone, were obtained with specific analyzer of image quality at various diameters of investigation. Ray-tracing optic simulations have been applied to dimension an optic toric/outer optic join that avoids scattering phenomena.

Results:

Clinical investigation demonstrated that the MINI TORIC READY IOL mechanical platform is rotationally stable. Optic simulation showed that aspheric toricity increases optical performance (MTF values ≥0.60 on both meridian) and makes IOL optic more robust to tilt (± 5°) and decentration (± 0,5mm). Optic toric/outer optic join resulted right dimensioned to not creating scattering phenomena at large pupil.

Conclusions:

All the investigated characteristics of this new aspheric toric intraocular lens permit to affirm that MINI TORIC READY IOL could be considered an effective, safe, and stable solution for correcting preexisting regular corneal astigmatism during cataract surgery.
