Bifocal and Multifocal Contact Lenses for Presbyopia and Myopia Control

Figure 5

Reconstruction of the binocular defocus curves drawn at the same scale from different studies: red line: 20 subjects (49–67 years of age) fitted with Softlens multifocal (Gupta et al. [99]). Blue line: 20 subjects (age: 45–63 yrs) Proclear Toric Multifocal (Madrid-Costa et al. [113]). Orange line: 20 subjects (age: 42–48 yrs) Acuvue Oasys (Madrid-Costa et al. [102]). Green line: 20 subjects (age: 42–48 yrs) Acuvue Oasys presbyopia (Madrid-Costa et al. [102]). Black line: 38 subjects (age: 48–62 yrs) Proclear Multifocal (Garcia-Lázaro et al. [116]). Dashed grey line: expected performance for fully presbyopic eyes (unpublished data from CEORLab-UMinho).
