Abstract Details
Purpose:
To analyse visual acuity, contrast sensitivity, aberrations, photic phenomena, patient satisfaction, and spectacle independence after cataract surgery with implantation of an extended range of vision intraocular lens (IOL) (Tecnis Symfony®), and a diffractive trifocal IOL (FineVision®).
Setting:
Severance Hospital, Yonsei University College of Medicine, Seoul, South Korea
Methods:
Prospective, comparative study. The study comprised of 45 eyes of 24 patients with implantation of an IOL after cataract phacoemulsification surgery. Twenty six eyes were implanted with an extended range of vision IOL (Symfony), and 19 eyes were implanted with a diffractive trifocal IOL (FineVision). Visual acuity was measured at distance (uncorrected and corrected distance visual acuity, UDVA & CDVA 4m), intermediate (uncorrected intermediate visual acuity, UIVA 50cm and 70cm), and near (uncorrected near visual acuity, UNVA, 33cm) at 3 months postoperatively. Defocus curves, contrast sensitivity, aberrations, dysphotopic phenomena, spectacle independence, and overall satisfaction were also compared.
Results:
The Symfony group achieved better UIVA 70cm than the FineVision group (p=0.008). On the other hand, the FineVision group showed better UNVA 33cm than the Symfony group (p<0.001). There was no significant difference in the UDVA, CDVA, and UIVA 50cm. Defocus curve evaluations showed better near visual acuity for the FineVision IOL at 33cm, whereas the Symfony group showed better intermediate visual acuity at 67cm-1m. There was no significant difference in contrast sensitivity, aberrations, dysphotopic phenomena. Over 85% of patients in both groups were spectacle independent. The average patient satisfaction score were 8 out of 10 in both groups.
Conclusions:
Extended range of vision IOL (Symfony) and diffractive trifocal IOL (FineVision) both achieved acceptable distance, intermediate, and near visual outcomes with high spectacle independence and patient satisfaction. Symfony IOL showed significantly better intermediate visual acuity, while FineVision IOL achieved better near visual outcome. This difference in visual outcome should be considered when selecting the appropriate IOL that satisfies the patient’s lifestyle needs and expectations.
