Abstract Details


To evaluate visual and optical performances of cataract eyes after phacoemulsification and trifocal Intraocular Lens (IOL) (RayOne Trifocal Lens – Rayner – UK ) implantation. Evaluation of a new method to improve visual outcomes based on eye selection and not on patients habits.


C.M.A. Centro Microchirurgia Ambulatoriale Monza – Italy


22 eyes of 11 patients mean age: 63.13 ± 9.33 years underwent uncomplicated phacoemulsification and trifocal IOL (RayOne Trifocal Lens – Rayner – UK) implantation. Preloaded IOL was implanted through a 2.4 corneal incision. Postoperatively, the following visual and refractive parameters were measured: distance (5m) near (40cm) and intermediate (80 cm) visual acuity, corneal topography and aberrometry, contrast sensitivity and defocus curve. Follow-up examinations were performed at day one, day two, one week one month 3 months 6 months.


Preoperative distance UCVA was 20/107 At one month distance UCVA is 20/20 , monocular and binocular uncorrected near vision are 20/24 and monocular and binocular intermediate vision are 20/26 92% of eyes achieved post operative refractive results within ± 0.50 diopter (sph equivalent)


RayOne Trifocal Lens provided good distance and near as well as intermediate visual acuity. This lens also improved quality of vision through remarkable diffraction efficiency and less penalization of contrast sensitivity.
