COMPARISON OF REFRACTIVE AND VISUAL OUTCOMES OF THREE PRESBYOPIA-CORRECTING INTRAOCULAR LENSES.

2021 
Purpose To evaluate and compare the clinical outcomes after cataract surgery with implantation of three different types of trifocal diffractive intraocular lenses (IOLs). Setting Hospital da Luz, Lisbon, Portugal. Design Prospective comparative case series. Methods 180 eyes of 90 patients undergoing phacoemulsification cataract surgery with implantation of one of these trifocal IOLs were enrolled: Tecnis Synergy (JJ p=0.107) and near VA (0.01±0.08, 0.01±0.06, 0.04±0.10; p=0.186). Likewise, no significant differences among groups were found in binocular uncorrected distance (p=0.572), near (p=0.929) and intermediate VA (p=0.327). In contrast, significant differences between groups were found in the visual acuity for the vergence demands of -0.50, -1.00, -2.00, -3.50 and -4.00 D (p≤0.045). No significant differences among groups were found either in the frequency, severity and bothersomeness of different disturbing visual symptoms, including glare and haloes (p≥0.129). More than 96% of patients in all groups did not require the use of spectacles at any distance after surgery. Conclusions The three trifocal IOLs evaluated provide an effective visual rehabilitation with minimal incidence of photic phenomena. A trend to obtain a wider range of functional focus was observed with the Tecnis Synergy IOL.
