Purpose
The purpose of this study was to compare the visual outcomes and subjective visual quality between bilateral implantation of presbyopia-correcting intraocular lens, TECNIS Synergy IOL (group A), and blended implantation of an monofocal, TECNIS Eyhance IOL with a TECNIS Synergy IOL (group B).
Setting
Brasília Ophthalmology Hospital, Brasília, Federal District, Brazil, South America.
Methods
A prospective, parallel group, randomized, double-masked, post market clinical study. Patients will be implanted with either bilateral implantation of the Synergy Intraocular Lens or Eyhance IOL in one eye and Synergy IOL in the contralateral eye. Binocular Corrected and Uncorrected Distant (4m), Intermediate (60cm) and Near (33 and 40cm) Visual Acuity were obtained. Binocular defocus curves will be performed under photopic conditions. Photopic and Mesopic contrast sensitivity with and without glare will be assessed. Reading speed will be tested for near and intermediate distances. Subjective questionnaires of visual quality were used - CAT questionnaire and TYPE questionare.
Results
The study included 60 subjects (120 eyes) who were implanted bilaterally with the bilateral Synergy IOL (n = 30) or blended IOL (n = 30), and binocular VA was evaluated 1 to 3 months (30–90 days) post-implantation. The bilateral Synergy IOL group showed superior visual outcomes compared with the Blended IOL group in binocular UIVA, UNVA and reading speed; and non-inferior outcomes in UDVA; Mean defocus curve from 0.00 to -3.00 diopter (D) ranged similar for both IOLs; better mean VA values were observed in the bilateral Synergy IOL group between -1.50 and -2.50 D compared with those of the Blended IOL group. Contrast sensitivity values were similar between the 2 groups in all conditions.
Conclusions
Preliminary results suggest that both groups promoted good quality of vision for long, intermediate, and contrast sensitivity. The bilateral Synergy IOL group showed superior visual outcomes compared with the Blended IOL group in reading speed and short distances visual acuity.
