Study Summary
The introduction of presbyopia-correcting intraocular lenses (PC-IOLs) has provided cataract and refractive surgeons the ability to provide patients with a wider range of visual success and spectacle independence post-cataract surgery.Multifocal (MFIOL) IOLs have the ability to provide near and distance vision, and in the case of trifocal IOLs, near, intermediate and distance. Despite the significant technological evolution of MFIOL's, the potential for visual disturbances, such as glare, halos and starbursts still exists-and in much greater frequency compared to their monofocal counterparts. Extended depth of focus (EDOF) IOLs aim to provide patients with a functional range of vision, with a similar visual disturbance profile to a monofocal lens. In this way, this subset of PC-IOL's can offer patients some degree of spectacle independence, with a significantly lower incidence of visual disturbances. The Vivity Extended Vision IOL is the first of its kind to offer Wavefront Stretching technology, providing patients with an excellent extended range of vision from intermediate to distance, as well as some functional near vision. Prior studies have demonstrated very good vision in both bright and dim lighting conditions, as well as a high degree of spectacle independence with the Vivity IOL, as compared to a monofocal IOL. Studies evaluating the ability of the Vivity IOL to provide a significant impact on patient lifestyle (e.g. patient independence from spectacles for most activities with a low rate of visual disturbances) in the United States in a 'real-world' setting have yet to be performed. In addition, influence of pre-and-perioperative variables such as sex, age, prior refractive surgery, IOL formula used, axial length, astigmatism, use of intraoperative aberrometry, femtosecond laser and pupillary expansion devices has yet to be evaluated on the postoperative success of this IOL. This study will be comprised of patients with visually significant cataracts w
Primary Outcome
Change in uncorrected distance visual acuity between baseline and at 3 months postoperative will be assessed.
