Abstract
OBJECTIVE
To compare the visual performance of two presbyopia-correcting intraocular lenses (IOLs) that combine both bifocal and extended depth-of-focus profiles, Artis® Symbiose® Plus (Symbiose Plus; Cristalens Industrie, Lannion, France) and Tecnis® Synergy® (Synergy; Johnson & Johnson Vision, Santa Ana, CA, USA).
METHODS
The medical records of patients with cataract bilaterally implanted with either Symbiose Plus or Synergy between January 2022 and January 2023 were assessed. The principal measures of postoperative findings included uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near (40 and 33 cm) visual acuity (UNVA), objective optical quality (OOQ) parameters, distance-corrected defocus curve analysis, and surveys of subjective satisfaction.
RESULTS
Total of 96 eyes from 48 patients were enrolled. Each group was equally composed of 24 patients, 48 eyes. There were no significant differences between the two groups on baseline characteristics. Both IOLs displayed excellent binocular UDVA, CDVA, and UNVA (40 and 33 cm) with no statistical difference (p = 0.467(UDVA), p = 0.584(CDVA), p = 0.096(40-cm UNVA), and p = 0.621(33-cm UNVA)). However, with regard to UIVA, the Synergy group showed significantly superior results (p < 0.001). In contrast, the Symbiose Plus group showed significantly better results on OOQ parameters and patient-reported quality of vision survey outcomes (both p < 0.001).
CONCLUSIONS
Both IOLs provided a decent continuous range of vision from near to far distance.
