Emmetrope Inc. is developing a line of accommodating intraocular lenses (IOLs) called ActaLens, ActaLens-Duo, and ActaLens-SC. The ActaLens models use a restrained hinge mechanism to allow movement of the optic when the eye focuses. Early clinical studies show the ActaLens providing over 0.5mm of movement and an estimated 0.5 diopters of accommodation. The dual optic ActaLens-Duo and shape changing ActaLens-SC are expected to provide even greater accommodation.
