Assessment of visual performance and quality of life obtained with twoextended depth of focus simultaneous vision lens platforms

Introduction and objectives: To assess differences in visual performance after implantation of two extended depth of-focus simultaneous vision intraocular lenses (IOLs) with different optical designs.
Patients and methods: A randomised prospective comparative interventional study in patients requiring cataract surgery for both eyes. Patients were divided into two groups: one given biconvex IOLs (Tecnis EyhanceTM, Johnson & Johnson Vision Care, Inc, Jacksonville, FL, USA) and the other inverted meniscus IOLs (ArtIOLsr25,
Voptica, Murcia, Spain). One month after the surgical intervention in the second eye, the binocular distance corrected visual acuity was measured at far, intermediate (66 cm), and near (40 cm) distances. Additionally, binocular distance-corrected defocus curves were obtained. Potential correlations of intermediate visual acuity (VA) with corneal spherical aberration (Z4 ∘) and pupil size were explored. The Catquest-9SF questionnaire was administered to all patients to assess their vision-related quality of life after IOL implantation.
Results: Overall, 30 patients (60 eyes) were assessed. Binocular distance corrected intermediate visual acuities of 0.20 logMAR (0.10;0.30) (p = 0.445), were achieved in both groups. The binocular distance corrected near visual acuity was 0.3 logMAR (0.25; 0,40) in the Tecnis EyhanceTM group and 0.4 logMAR (0.30;0.50) in the ArtIOLsr25 group (p = 0.050). Intermediate visual acuity was weakly correlated with corneal spherical aberration and pupil size. The Catquest-9SF score was close to 1 in both groups, but better in the Eyhance group, and the difference was statistically significant (p = 0.035).
Conclusions: Both the Tecnis EyhanceTM and ArtIOLsr25 IOLs achieved a binocular distance-corrected intermediate VA of 0.2 logMAR, without compromising distance VA. No differences were observed between the two groups in the outcomes experienced by patients in their daily lives related to their vision problems after cataract surgery.
