Initial Objective And Subjective Outcome Data For The New Hoya Vivinex Gemetric Trifocal Intraocular Lens.

To report initial results of a new to be launched in 2022 diffractive trifocal IOL, the Vivinex Gemetric, (HOYA Surgical Optics, Singapore), both non-toric and toric versions. The IOLs were implanted to replace the lens during cataract and refractive lens exchange surgery.“Real world” data was collected using CLEARlog software during the pre-commercial launch phase.

Private practice in South Wales, United Kingdom.

A single surgeon used the CLEARlog software to upload pre-operative, surgical, and post-operative data for patients receiving the Gemetric trifocal IOL. Parameters evaluated were uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), manifest residual spherical equivalent (MRSE), spectacles usage at different distances, photic phenomena, and patient satisfaction. All visual acuity measurements were reported using LogMAR scale. Follow up period ranged from 7 to 105 days. Eyes that have not yet concluded post-op follow-up are not included.

Initial data for 56 eyes were analyzed. Of these, 96% had UDVA ≥ 0.2, 89% had UIVA ≥ 0.3, and 96% had UNVA ≥ 0.3. 73.6% of eyes were within ± 0.50 D MRSE and 88.7% were within ±1.0 D MRSE. Spectacle independence was achieved in 96% for distance, 98% for intermediate and 89% for near (reading) where patients reported never needing to use glasses at each distance. Photic phenomena were reported as either Never or Sometimes in 91% for halos, 95% for starbursts and 95% for glare. In 100% of cases these phenomena were either Mild or Moderate, but never severe. 100% of cases were Very Satisfied or Mostly Satisfied (89% and 11% respectively), 100% say they totally or mostly achieved their desired objective, and 100% would recommend this procedure.

The Vivinex Gemetric trifocal IOL yielded very high levels or spectacle independence and patient satisfaction, with low rates of photic phenomena (which were not severe when they occurred), and a very high willingness to recommend the surgery to friends or family members. MRSE outcomes could be link to shorter follow up period, which is unavoidable in real world cases. The overall patient satisfaction and spectacles independence rate were high. The Vivinex Gemetric trifocal IOL is a new trifocal lens that performs at least as well as comparable lenses, with excellent patient satisfaction ratings, and offers surgeons an alternative option to discuss with patients.
