VERION^® – The influence of expressed image-guided system technology on postoperative astigmatism control

DOI: 10.5935/0034-7280.20200020

Abstract

Objective:

To evaluate the astigmatism induced by cataract surgery through the phacoemulsification (PHACO) technique guided by the VERION^® surgical planner, in an ophthalmological service of Paraná.

Methods:

This is an observational study with retrospective individualized evaluation of medical records, analyzing 37 eyes of 20 patients who underwent cataract surgery using the PHACO technique using VERION^® and non-toric intraocular lens implantation at the Hospital de Olhos de Cascavel – PR in May 2016.

Results:

Within our sample of 37 eyes approached with VERION^® assistance, 43% of study participants (n=16) had reduced initial astigmatism, including elimination of more severe degrees of astigmatism (≥2.5 D).

Conclusion:

The impact of VERION^® was significant as it allowed the correction of previous astigmatism of a part of the sample. In eyes that had surgically induced astigmatism, this complication was less clinically relevant compared to conventional technique corneal incisions.
