Brief summary
The objective of this study was to evaluate the clinical and patient reported outcomes after bilateral implantation of the AcrySof™ IQ Vivity™ Toric intraocular lens.
Detailed description
This is a prospective interventional case series of 30 patients who underwent cataract surgery and bilateral implantation of the AcrySof™ IQ Vivity™ Toric intraocular lens. This study is represented by an Asian cohort of patients and the study evaluations were focused not only on clinical visual outcomes but also on real-life patient reported outcomes such as dysphotopsias, spectacle independence and daily visual tasks all of which were measured at 1 month and up to 3 months postoperatively. The objective would be to provide insight into the performance of this intraocular lens in Asian patients.
