Abstract Details


To evaluate binocular visual outcomes including visual acuities at different distances, spectacle independence, visual symptoms, and patient satisfaction in patients undergoing cataract surgery with implantation of the TECNIS® Symfony Extended Range of Vision intraocular lens (IOL). All patients were targeted for emmetropia in the dominant eye, and micro-monovision between 0.5 to 0.75 D in the non-dominant eye.


Lee Hung Ming Eye Centre, Gleneagles Hospital, Singapore


A single-center, single-surgeon, six-month, retrospective/prospective, bilateral open-label, observational study. Subjects requiring with bilaterally implantated TECNIS® Symfony IOL were enrolled in the study. Key measurement variables at 4-8-week and 4-6-month postoperative time points included: (i) Binocular unaided visual acuities for distance (UDVA), intermediate at 70cm (UIVA) and near at 40cm (UNVA), (ii) Spectacle independence and patient satisfaction assessed through a questionnaire.


A total of 23 subjects with the 4-6 month assessment were included. 100% of patients achieved UDVA of 20/30 or better, 78.3% achieved UIVA of 20/30 or better, 87.0% achieved UNVA of 20/30 or better. No glasses were needed for distance, intermediate and near in 100%, 100% and 96% respectively. None reported severe photic phenomenon, 21.4% reported mild halos, 26.09% reported mild glare and 8.7% reported mild starburst. The satisfaction scores (median) with uncorrected visual acuity were 8 for each distance (far, intermediate and near). 93% would recommend the lens to friends/family, and 93% would choose the same lens again.


The 4-6-month study results for the TECNIS® Symfony IOL demonstrated good binocular uncorrected visual acuity at all distances. Micro-monovision led to good overall performance from far to near (40 cm) distances; and targeting for micro-monovision of 0.5 – 0.75 D can further improve uncorrected near vision without compromising intermediate or distance vision. Results showed a high degree of spectacle independence amongst all subjects. Satisfaction rates were also high for all subjects. The occurrences of optical visual symptoms were within the typical expected rates seen in monofocal IOLs.
