    Lessons learned in adapting EDOF IOLs


    Early clinical outcomes

    The average age was 66.4 ± 7.1 years (range age 52 to 79) and 65% of the patients were female. 

    Target refractions ranged from +0.25 D to -0.50 D, with a slightly lower mean target for the non-dominant eyes (-0.20 D, vs. -0.03 D for the dominant eyes). In all, 64% of eyes were within 0.25 D of the intended refractive target, while 83% were within 0.50 D. 

    All eyes had ≤ 0.50 D of residual refractive cylinder at 1 month, with 75% of eyes having 0.0 D of residual cylinder. There was no significant difference in residual cylinder by type of IOL (sphere or toric EDOF).

    The best-corrected distance visual acuity (BCDVA) at 1 month was 0.02 logMAR, or about 1 letter worse than 20/20. No eye had a BCDVA worse than 20/25, and 62.5% had a BCDVA of 20/20 or better. All but 1 eye had 20/20 best-corrected near visual acuity (BCNVA).

    Mean monocular uncorrected distance visual acuity (UCDVA) was 0.15 logMAR, or between 20/25 and 20/30, with a standard deviation of 0.11 logMAR (about 1 line of vision). UCDVA was statistically significantly better (p=0.03) with the Symfony Toric IOL than with the Symfony IOL, by about 1 line (0.11 logMAR or ~20/25 vs. 0.19 logMAR or ~20/30). There was no statistically significant difference in UCDVA between the dominant and non-dominant eyes (p=0.19)Figure 2. Mean monocular UCIVA was 20/20 and UCNVA was 20/30 at 1 month.Mean monocular uncorrected intermediate visual acuity (UCIVA) was 20/20 and near (UCNVA) was 20/30 (See Figure 2).
