A deformable intraocular lens (IOL)comprises a deformable optic,having an annular edge around its periphery, and at least two haptics, each having a proximal portion and a distal portion relative to the optic. Each haptic extends from a different position on the annular edge of the optic and can be compressed. The IOL further comprises at least one tab extending from the annular edge of the optic at a position different from the proximal portion of each of the haptics. The or each tab can adjust the folding characteristics of the IOL, which in turn can control the speed and orientation of the IOL on injection into a patient's eye and ensure greater reliability of desired injection.
