A contact lens incorporating one or more surface modified zones on the anterior surface of the lens may be utilized to generate a friction driven rotational force when the upper and/or lower eyelids pass over the one or more regions during blinking. A small difference in the coefficient of friction between the modified and unmodified regions of the lens may result in an equivalent rotational force to that of a thickness gradient lens. This small difference in the coefficient of friction produces a means to orient and stabilize the contact lens on eye.

Friction stabilized contact lenses

The present invention is directed to a method and means for enabling contact lens wearers to photograph their own eyes using an electronic device with a camera such as an iPhone with a macro lens, for example, Olloclip&#xae; Macro Pro Lens Set 7&#xd7; lens, and a custom three-dimensional printed eyecup attachment. The eyecup attachment is designed to position the camera at a suitable and reproducible distance from the eye to ensure that the system can focus appropriately on the lens details. The eyecup attachment also serves to block stray light and diffuse the ambient lighting. In addition, the eyecup attachment ensures that the camera is held in the correct orientation while photos are being captured. The capture images are analyzed using image processing software to determine the angel of rotation of the contact lens.

Method and means for evaluating toric contact lens rotational stability

The invention provides an improved rotationally stabilized contact lens design and method of designing such a lens which minimizes stabilization time of the lens while maximizing the lens on-eye comfort. The lens and the method of designing the lens utilizes and combines non-circularity and thickness differential aspects resulting in equivalent or minimized stabilization time, ease of insertion and manufacturability as well as maximum comfort that is improved over that of what either aspect can achieve independently.

This invention discloses methods and apparatus for providing pulsatile release of active agents via a punctal plug inserted into a punctum. A tube is provided which may be inserted into a cavity of a punctal plug. One or more pulsatile delivery units are arranged in a generally linear fashion within the tube. The pulsatile delivery units include a core comprising the active agent and an encapsulation layer around the core.

Pulsatile release of medicaments from a punctal plug

A punctal plug or lacrimal insert comprising a microelectromechanical system pump and associated reservoir may be utilized to deliver precise dosages of an active agent into the eye though the tear film. The microelectromechanical system pump comprises four main components; namely, a reservoir, a pump, a series of valves and a vent. The microelectromechanical system pump is positioned within a cavity in the punctal plug. The microelectromechanical system pump is positioned with a cavity in the punctal plug.
