Designed to perform optimally even in a decentered or tilted position
• IOL displacement is a common occurrence: 33% of patients experience postoperative decentering and/or tilt10
• When decentering of lenses occurs, resolution of the lens is decreased resulting in a loss of visual acuity
• The Afinity™ Collamer® Aspheric IOL is optimized to accommodate decentering and tilt without loss of visual acuity
Modulation Transfer Function (MTF) analysis of different lenses demonstrates exceptional performance with the Afinity™ Collamer® Aspheric IOL in on-axis, decentered, and tilted positions9
Greater MTF=Higher quality of vision
Provides sharp image quality and increased functional vision by design
• Modeled on a curved retina, the Afinity™ Collamer® Aspheric IOL is optimized to simulate in situ conditions
Afinity™ Aspheric IOL Design
• Small amount of negative spherical aberration compensates for the positive aberration of the average cornea and the curved retina
o The total eye (cornea+IOL+curved retina) carries a residual positive spherical aberration
