Eyhance IOL maintains intermediate vision advantage at 5 years

BARCELONA, Spain — Patients implanted with the Tecnis Eyhance IOL maintain enhanced visual performance for intermediate distance activities after 5 years with constant satisfaction, according to a study.
Tecnis Eyhance (Johnson & Johnson Vision) belongs to a new generation of monofocal IOLs designed to slightly extend the depth of focus with no compromise on vision quality. The study, presented by Giovanni Romualdi, MD, at the European Society of Cataract and Refractive Surgeons meeting, started in 2019 and included 80 eyes of 40 patients, seven of which were lost to follow-up. The comparator was the standard monofocal Tecnis ZCB00 (Johnson & Johnson Vision).
Over 5 years, only two eyes, one in each group, developed posterior capsular opacification, which was likely due to the Tecnis platform’s square-edge design that ensures minimal migration of lens epithelial cells after implantation, Romualdi said.
Distance and near vision were comparable to the standard monofocal and stable over the 5 years. In addition, Eyhance maintained an advantage at intermediate distance.
“The Eyhance maintained a similar binocular defocus curve and similar results in the 5-year follow-up and confirmed the statistically significant superiority for powers of –1 D and –1.5 D,” Romualdi said.
Binocular photopic contrast sensitivity decreased slightly but not significantly between 6 months and 5 years for the lower spatial frequencies.
Quality of vision was measured by the Optical Quality Analysis System (QQVision), and the aberration parameters were assessed with the Osiris-T topo-aberrometer and the MS-39 topographer (both CSO), showing no change from 6 months to 5 years.
“Just the internal higher-order aberrations and spherical aberration showed a slight increase without being statistically significant,” Romualdi said.
Dysphotopsia was measured using the iPad-based Aston halometer app.
“The patient is in a dark room at a distance of 200 cm from an iPad, and after 1 minute of adaptation, the exam starts. The halometer generates a glare map with numerical values,” Romualdi said.
Eyhance showed a dysphotopsia profile comparable to the standard monofocal IOL.
Patient satisfaction remained high, with 70% of patients not using spectacles for daily tasks at intermediate distance.
