Patient Satisfaction With A New Trifocal Iol Platform Offering Two Complimentary Light Distributions

To evaluate the subjective satisfaction of patients after implantation of Vivinex Gemetric and Vivinex Gemetric Plus trifocal IOLs (HOYA Surgical Optics).

Multicenter clinical trial, randomized, prospective

A standardized questionnaire was used in 124 patients at the 6 month follow-up visit to evaluate visual disturbances, as well as spectacle independence and visual satisfaction for distance, intermediate and near vision. Data analysis was split into three groups: Vivinex Gemetric both eyes (G-G), Vivinex Gemetric Plus both eyes (GP-GP) and combination of Vivinex Gemetric and Vivinex Gemetric Plus (G-GP). Cylinder powers up to 3.00D were included. First eye’s in the G-GP group were implanted with Gemetric. No test of distance or near dominance was mandated.

In the groups G-G (n=36), G-GP (n=36) and GP-GP (n=52) severe glare was described by 2.8%, 0%, 3.8% of patients, severe halos by 13.9%, 16.2%, 7.7% and severe starburst by 8.3%, 10.8%, 3.8%, with no significant difference between the groups. Satisfaction with vision at far was stated by 97.2%, 94.4%, 94.2%, at intermediate by 97.2%, 100%, 98.1% and at near 97.2%, 100%, 100%. The proportion of patients who never wear spectacles in G-G, G-GP and GP-GP groups are 91.7%, 94.4% and 98% for far, 94.4%, 97.2% and 98% for intermediate, 80.6%, 91.7% and 84.6% for near, respectively.

All groups; G-G, G-GP and GP-GP reported high patient satisfaction and high spectacle independence, and a low incidence of visual disturbances.
