Hovanesian, 2008 Hovanesian 2011 Crystalens: How it Works Primary Force: Ciliary Muscle Accommodation causes the ciliary muscles to contract, displacing the vitreous mass & forcing the lens forward
3
Hovanesian, 2008 Hovanesian 2011 Crystalens: How it Works Secondary Force: Optic Arching Capsular contraction slightly distorts the optic as it is forced anteriorly, changing the radius of the lens Distance Near Δ 2.50 D

Hovanesian, 2008 Hovanesian 2011 Crystalens AO Accommodating IOL Aberration-free optic design Maintains depth of focus of spherical IOL Improves contrast sensitivity over spherical IOLs Aspheric surface on anterior and posterior surfaces Less sensitive to decentration
5
Hovanesian, 2008 Hovanesian 2011 Effect of SA on Image Quality Spherical aberration degrades retinal image quality. Reduces contrast sensitivity and low-contrast visual acuity High-contrast visual acuity usually not affected Creates halos SA = 0 SA = +0.45 mm 20/40 Letter E
