Abstract
Purpose :
For patients who are not candidates for bilateral multifocal IOL or who chose EDOF (extended depth of focus) IOL (Symfony Optiblue) for their first eye, implanting a multifocal IOL (Tecnis Odyssey) in the second eye may be a method to achieve better near vision in those desiring improved reading without decreasing intermediate or distance vision.
Methods :
7 patients with bilateral cataracts implanted with Symfony Optiblue IOL who desired improved reading vision were implanted with Tecnis Odyssey IOL in their second eye and had visual acuities measured within a 60 day period. All eyes were targeted for plano. Visual acuities were measured at 6 m (distance), 60 cm (intermediate), and 40 cm (near) uncorrected, and best corrected for distance both unilaterally and bilaterally.
Results :
For uncorrected DVA, Odyssey (20/20, LogMAR 0.012 ± 0.037) performed nearly as well as Symfony (20/20, LogMAR 0 ± 0), and bilaterally, remained at 20/20 (LogMAR 0.014 ± 0.037). Similarly, for IVA, Odyssey (20/20, LogMAR 0.001 ± 0.115) performed nearly as well as Symfony (20/20, LogMAR -0.014 ± 0.067), and bilaterally, improved to 20/15 (LogMAR -0.097 ± 0). For NVA, Odyssey (20/25, LogMAR 0.124 ± 0.093) performed better than Symfony (20/30, LogMAR 0.200 ± 0.0845). Bilaterally, NVA improved to 20/20 (LogMAR 0.039 ± 0.070).
Best corrected DVA remained at 20/20 for Odyssey (LogMAR 0 ± 0), Symfony (LogMAR -0.031 ± 0.081), and bilaterally (LogMAR -0.31 ± 0.081). Best corrected IVA remained at 20/20 for Odyssey (LogMAR -0.55 ± 0.052), improved to 20/15 for Symfony (LogMAR -0.086 ± 0.092), and bilaterally remained at 20/15 (LogMAR -0.114 ± 0.072). Best corrected NVA remained at 20/20 for Odyssey (LogMAR 0.039 ± 0.07) and improved to 20/25 for Symfony (LogMAR 0.128 ± 0.126), and bilaterally remained at 20/20 (LogMAR 0.277 ± 0.047).
Conclusions :
EDOF IOLs are generally believed to provide improved distance and intermediate vision compared to multifocal IOLs. Despite this, Odyssey may be comparable to Symfony in terms of distance and intermediate vision. Additionally, Odyssey provides an increase in near vision acuity. This suggests that patients who are not a candidate for bilateral multifocal implantation or desire improved near vision after implantation of Symfony may achieve this with an Odyssey IOL in their second eye.
