Abstract Details

Purpose:

To assess the efficacy and safety of bilateral implantation with the Rayner RayOne Trifocal Toric Intraocular lens.

Setting:

Multi-centre multi-surgeon international evaluation

Methods:

Subjects underwent bilateral refractive lens exchange or cataract surgery with RayOne trifocal intraocular lenses (Rayner, UK). Preoperative manifest refraction, and uncorrected visual acuity at far, intermediate, near distances were compared with follow-up at 1 week and 1 month. Dysphotopsias, quality of vision issues and other adverse events were reported.

Results:

20 eyes of 10 patients with mean age 66.0 ± 7.7 years were included. Mean pre-op corneal cylinder was 1.44 ± 0.94D and one month post-op mean corneal cylinder was 0.41 ± 0.27D. One month following surgery, average binocular UCDVA was 0.00 ± 0.09 logMAR and UCNVA was 0.05 ± 0.05 logMAR.  UCIVA was -0.03± 0.05 logMAR.  All eyes were within 0.75D of cylindrical correction with 71% of eyes being within 0.50D.  Patients experienced mild nighttime halos that were non-disabling.

Conclusions:

Implantation of the RayOne trifocal toric intraocular lenses allows for safe and accurate restoration of near, intermediate, and distance visual acuity and correction of astigmatism.
