The investigational enVista Toric IOL, Model MX60T, and the currently approved Model MX60, are identical with the exception of the addition of toric optics and axis marks on the posterior optic surface for the correction of astigmatism on the Model MX60T. Both lenses have an aspheric biconvex optic with a modified C haptic monoblock, single-piece design. The design and material of both the MX60 and MX60T allow them to be folded and inserted through small incisions to minimize the possibility of surgically induced astigmatism (SIA).
