Visual Efficacies Of Enhanced Monofocal, Diffractive Extended Depth Of Focus (Edof) And Non-Diffractive Edof Iols.

To compare the visual efficacies of three presbyopia-correcting intraocular lenses (IOLs) (enhanced monofocal: Eyhance®, extended depth of focus (EDOF): Symfony® and PureSee®). 

Bucheon St. Mary’s Hospital, Catholic University of Korea

180 eyes (90 patients; Eyhance– group 1, n= 60, diffractive type EDOF: Symfony®– group 2, n= 60, non-diffractive type EDOF: PureSee®- group 3, n= 60) who underwent cataract surgery were retrospectively enrolled. Uncorrected and corrected near (UNVA, CNVA), intermediate (UIVA, CIVA), and distant (UDVA, CDVA) visual acuity, manifest refraction spherical equivalent (MRSE), and satisfaction score were evaluated before and after surgery.

The postoperative UNVA of group 2 and 3 (0.16 ± 0.11 and 0.15 ± 0.10 logMAR, respectively) was significantly better than that of groups 1 (0.34 ± 0.21) (P<0.05). Group 2 and 3 provided significantly better defocus results from -2.5 D to -3.0 D of defocus range (corresponding to 25~33 cm) compared with groups 1, respectively (P<0.05). The near vision satisfaction of group 2 and 3 (1.68 ± 1.12 and 1.59 ± 0.86, respectively) was significantly better than that of group 1 (2.24 ± 1.48) (P<0.05). The glare and halo of group 1 and 3 (1.53 ± 0.85 and 1.47 ± 0.71, respectively) were significantly lower than those of groups 2 (2.37 ± 1.26) (P<0.05).

The enhanced monofocal and two EDOF IOLs showed similarly good uncorrected distant and intermediate vision. The near vision with two EDOF IOLs is better than that with the enhanced monofocal IOL. The glare and halo of enhanced monofocal and non-diffractive EDOF IOLs were significantly lower than those of diffractive EDOF IOL.
