The embodiments disclosed herein include improved toric lenses and other ophthalmic apparatuses (including, for example, contact lens, intraocular lenses (IOLs), and the like) that includes one or more refractive angularly-varying phase members, each varying depths of focus of the apparatus so as to provide an extended tolerance to misalignments of the apparatus. Each refractive angularly-varying phase member has a center at a first meridian (e.g., the intended correction meridian) that directs light to a first point of focus (e.g., at the retina of the eye). At angular positions nearby to the first meridian, the refractive angularly-varying phase member directs light to points of focus of varying depths and nearby to the first point of focus such that rotational offsets of the multi-zonal lens body from the center of the first meridian directs light from the nearby points of focus to the first point of focus.

An intraocular lens insertion apparatus includes a distal end member which is inserted through an incision in an eyeball of a patient, an opening member provided for the distal end member through which an intraocular lens is ejected, and an indicating means provided for the distal end member. The indicating means is used for indicating that an entire part of the opening member is inside a cornea of the eyeball or inside a sclerocornea of the eyeball with respect to an external flap of the incision.

This document describes intraocular lenses and methods for their use. For example, this document describes intraocular lenses that are shaped with a concave posterior peripheral portion that mitigates occurrences of dysphotopsia. The intraocular lenses described herein are designed to reduce positive and negative dysphotopsias after cataract surgery.

A bodily implant is provided to support body tissues of a patient. The bodily implant includes a strip having a first portion and a second portion. The strip is configured to be stretched in a manner such that the second portion is stretched from a first length to a second length. The second portion of the strip is configured to maintain the second length. The strip is further configured to be disposed proximate to the patient's body tissues.

Implantable devices including conduits that have markings along the length of the conduit are described herein.

A silicone prosthesis delivery apparatus and associated methods are disclosed for facilitating the transport and subsequent insertion of a silicone prosthesis into a surgically developed pocket of a patient. In at least one embodiment, a flexible, substantially funnel-shaped delivery sleeve is constructed out of a material having a lubricating additive that forms a textured inner surface within the delivery sleeve. An entry portion of the delivery sleeve defines a stretchable entry opening configured for allowing the prosthesis to pass therethrough to a position inside the delivery sleeve. An opposing exit portion defines a stretchable exit opening configured for allowing the prosthesis to pass therethrough when the prosthesis is subsequently expelled from the delivery sleeve. A volume of surgical lubricating fluid coats the textured inner surface of the delivery sleeve so as to reduce the coefficient of friction between the inner surface of the delivery sleeve and the prosthesis.

The present disclosure relates to the field of endoscopy. Specifically, the present disclosure relates to systems and methods which allow the distal portion of a catheter to be visualized within the body using a colored marker and one or more secondary markers. In particular, the present disclosure relates to systems and methods which indicate when a medical device is properly positioned for deployment within a body lumen.

An implantable prosthesis for repairing a defect in a muscle or tissue wall. The prosthesis comprises a body of biologically compatible prosthetic material having a preformed three-dimensional contoured shape that independently assumes a three-dimensional curved shape configured to conform to the muscle or tissue wall. The body may be formed of a mesh fabric employing a knit construction. The body may be configured with one or more mechanical characteristics, individually or in any combination, having defined properties which may enhance the ability of the prosthesis to be handled in a surgical, robotic environment while meeting the performance and physical characteristics for soft tissue repair and reconstruction. One or more visual indicia may be provided to facilitate positioning and/or placement of the prosthesis at the muscle or tissue wall.
