Design of the SML
The SML was invented by Gabor Scharioth, MD, PhD, who published a proof of concept paper in the Journal of Cataract and Refractive Surgery in August 2015.
The single-piece hydrophilic IOL has a 13 mm overall diameter and 6 mm optic that features a +10 D add in the central 1.5 mm. The rest of the optic is refractory neutral.
The SML is an add-on lens for implantation in the ciliary sulcus. It features a convex-concave optic, 4-point fixation with flexible haptics, a non-torque and square design, and can be implanted through a 2.2 mm incision. The lens is not available preloaded, but is delivered using a standard cartridge.
The features of the lens allow for safe and easy surgery, perfect fit in the ciliary sulcus with rotational stability, and avoidance of both iris capture and touch with the pseudophakic IOL.
“A great advantage of this lens is that its implantation is reversible,” Dr. Srinivasan said.
