Real World Experience With Vivity Edof Iol In Cataract Patients With Concurrent Eye Pathology Or Post Refractive Surgery Patients

Extended depth of focus (EDOF) intraocular lens (IOL) are designed to provide a high degree of spectacle independence in cataract surgery patients with less visual side effects as compared to refractive/diffractive multifocal (MF) IOL. In patient with less than ideal situation, ie with concurrent mild ocular pathology or post refractive surgery patients, multifocal IOL implant may not be suitable, and EDOF lenses may be a better option. We seek to find out how the real world visual performance and satisfaction outcomes of a new EDIOF IOL (Alcon Vivity/Vivity Toric) in a clinic population who were deemed not suitable for MF IOL.

Retrospective, single-centre, single-surgeon,nonrandomised, noncomparative case series.

Vision parameters analysed included preoperative unaided vision, postoperative vision (distance, intermediate and near) at month one, target refraction status, and questionnaires regarding  incidence of side effects (glare/haloes) and functional satisfaction such as dependency on glasses post-surgery. We also analyse by subgroup the performance of these EDOF lenses. 116 eyes in 83 consecutive patients were analysed.

There was significant improvement in preoperative vs postoperative unaided vision at all distances.  Mean unaided distance visual acuity pre-operation improved from 6/15 to 6/9.5 at month one. 48 percent and 70 percent of patients reported satisfaction with near and intermediate vision respectively.  Patient vision satisfaction and functional ability is generally favourable.

Alcon Vivity EDOF IOL gives acceptable unaided near, and excellent intermediate and far vision at month one post surgery,  and high degree of spectacles independence in cataract patients deemed not suitable for MF IOL with minimal side effects.
