ActaLens-SC ( Shape-Change)
• Same platform and hinge design as fixed optic version
– Again, .4 MM movement and 10 to 15 degrees flexion
expected
• 2 layer lens. Base layer firmer silicone. Top layer of
softer silicone deforms over base layer as haptics flex.

Summary
• ActaLens
– UBM, Pentacam, and Lenstar proven movement
– Novel, capsule-independent mechanism
• Actalens-Duo: Dual optic design
– Increases accommodative effect
• Actalens-SC
– Using same clinically tested platform from first
generation Actalens, > 5 D total pharmacological
accommodation expected, lens power
independent.
– Objectively measurable accommodation greater
than 2 D will be crucial to success.

Evaluation of Movement at 20
Months
• Independent analysis
– VIROS, N. Hirnshall MD, PhD, Findl, O, MD
• Lenstar PCI measurement of cyclo/pilo
axial shift at 20 months confirms
movement:
• .46 MM + .13 total movement of ActaLens
• no axial shift in control group
