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

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

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 = mm 20/40 Letter E

Hovanesian, 2008 Hovanesian 2011 Crystalens AO Outcomes Data Collection Uncorrected distance (UCDVA) and near (UCNVA) visual acuities entered into SurgiVision ® DataLink IOL Registry Data from: Our site: all eyes with data entered Global data: all Crystalens AO eyes entered into database Data from 1 and 3 month postoperative visits

Hovanesian, 2008 Hovanesian 2011 Conclusion Crystalens AO provides acceptable distance vision and functional near vision. Predictable outcomes: Mean MRSE within 0.5 D of plano in both groups
