Description
Ben Connell and Jack Kane compare cataract lens implants that correct mild astigmatism with plain implants, in eyes with low levels of the condition. Toric lenses that fix astigmatism clearly help at high levels; the gain at low levels is in doubt. Their 2026 study reviews eight hundred four eyes where a standard calculator advised the mildest toric lens.
After surgery, the toric group had slightly less leftover astigmatism on refraction tests. Yet unaided and corrected sharpness of sight were the same overall in both groups. In one subgroup, defined by the direction of the eye's curve, plain lenses actually gave better unaided sight. The authors say the toric gain at this low level is real on paper but small in daily vision.
