Abstract: A multi-part intraocular lens (IOL) with an interchangeable optic seated on a base and secured by a locking mechanism. The optic comprises an anterior surface with a diameter greater than a diameter of a ring of the base. The posterior side of the optic has a posterior surface, a transition region for contact with the base, and sidewalls and tabs radially outward of the transition region. The sidewalls and tabs overlap at least a portion of the ring to reduce or even prevent decentration and tilt of the optic. Each tab has a lateral extension for coupling to the base.

Abstract: An ophthalmic device includes an optic including an optic axis and a haptic structure coupled with the optic. The haptic structure includes an inner ring comprising a plurality of hinges such that portions of the inner ring reside at different radii from the optic axis. The haptic structure further includes a first loop extending from the inner ring and having two points of connection to the inner ring and a second loop extending from the inner ring and having two points of connection to the inner ring. The second loop is oriented opposite the first loop.

Abstract: An ophthalmic lens may comprise a posterior optic surface, an anterior optic surface, and an optic edge between the posterior optic surface and the anterior optic surface, wherein the optic edge forms a substantially circular perimeter having a thickness that varies periodically. The thickness of the optic edge may vary periodically for at least two cycles. Additionally, or alternatively, the ophthalmic lens may comprise an optic skirt coupled to the optic edge. The optic skirt can be configured to inhibit transmission of light around the optic edge.

Abstract: A modular optical implant, which may comprise a base ring and an optic with features that enable assembly, alignment, and stabilization of adjunct optics. The optic may have features that interface with other optics and improve optical outcomes through rigid alignment of adjunct optics, mitigation of anterior capsule opacification, in vivo identification of optical features while implanting the lens, and reduction of refractive error. More generally, some embodiments may be an optical implant, which may comprise a posterior optic surface, an anterior optic surface, an optic edge between the posterior optic surface and the anterior optic surface, a locking tab coupled to the posterior optic surface, and an optic stabilizer coupled to the anterior optic surface.

Abstract: Certain aspects of the present disclosure provide techniques for performing surgical ophthalmic procedures, such as cataract surgeries. An example method of determining one or more intraocular lens (IOL) parameters for an IOL to be used in a cataract surgery procedure includes generating, using a fused machine learning model, recommendations including one or more IOL parameters for the IOL to be used in the cataract surgery based, at least in part, on first predicted lens behavior for each of one or more IOLs by an emulated finite element analysis (EFEA) model and the second predicted lens behavior for each of the one or more IOLs by an IOL power calculator (IPC) machine learning model.
