Purpose

To report initial results of a new 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.

Setting

Private practice in South Wales, United Kingdom.

Methods

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 monocular uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), 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. Eyes that have not yet concluded post-op follow-up are not included.

Results

Data for 160 eyes were analyzed. Monocular UDVA, CDVA, UIVA and UNVA are 0.04±0.14, -0.01±0.10, 0.23±0.12 and 0.21±0.12logMAR, respectively. Average MRSE is -0.37D with SD of 0.44D. Complete spectacle independence was achieved in 96% for distance, 97% for intermediate and 89% for near (reading) where patients reported never needing to use glasses at each distance. Photic phenomena were reported as either “none” or –“mild” in 92% for halos, 97% for starbursts and 99% for glare. 99% of cases were Very Satisfied or Mostly Satisfied (91% and 8% respectively), 100% say they totally or mostly achieved their desired objective, and 100% would recommend this procedure.

Conclusions

The Vivinex Gemetric trifocal IOL yielded very high levels of spectacle independence and patient satisfaction, with very low rates of photic phenomena, and a very high willingness to recommend the surgery to friends or family members. The Vivinex Gemetric trifocal IOL is a new trifocal lens that performs at least as well as comparable lenses and offers surgeons an alternative option to discuss with patients.
