Abstract: Hydrophilic coatings for implants are disclosed. The coatings are hydrophobically bound to the implant, but are not covalently cross-linked or covalently anchored to the implant's surface.
Abstract: An apparatus for determining aberrations of an eye includes a patient head rest allowing for positioning adjustment. The patient head rest is operable with an optical table having a base. The base includes a probe beam generating apparatus, probe beam directing optics which itself comprises a beam splitter; a mirror; and a lens. The probe beam directing optics is capable of directing a probe beam toward an eye of a patient positioned on the patient head rest. Video image components are provided and comprise a light source, a mirror; and a video camera. The video image components are capable of generating an image of an eye of a patient positioned on the patient head rest. Eye fixation components generate a target that the eye of a patient positioned on the patient head rest can view. The eye fixation components comprise a fixation target, a light source, a lens, and a mirror.

Abstract: The present invention provides a microkeratome for creating lamellar sections from a biological tissue containing a blade-post assembly which improves precision and predictability by preventing undesired blade wobbling. Methods and devices are disclosed to inhibit blade wobbling, preferably frictional fittings are employed to secure the blade (or blade assembly) within the microkeratome. By biasing the blade into a secure position, wobbling during usage is substantially lessened if not eliminated. A modified blade assembly is disclosed having a post that is mated to a surgical blade. In one embodiment of the invention, the post can have one or more protrusions that engage at least one side of a recess in the microkeratome thereby creating a frictional fit sufficient to prevent movement of the blade while cutting. In another embodiment of the invention, the recess can include certain biasing elements that engage the post to prevent blade wobbling.

Abstract: The present invention is directed to a drug delivery device for a human eye. The human eye has a sclera, an inferior oblique muscle, and a macula. The device of the present invention includes a pharmaceutically active agent, and a geometry that facilitates the implantation of the device on an outer surface of the sclera, beneath the inferior oblique muscle, and with the pharmaceutically active agent disposed above the macula. Methods of delivery a pharmaceutically active agent to the posterior segment of the human eye are also disclosed.
Abstract: Drug delivery devices, and methods of delivering pharmaceutically active agents to a target tissue within a body using such devices, are disclosed. One drug delivery device includes a body having an internal surface for placement proximate a target tissue and a well having an opening to the internal surface. An inner core comprising a pharmaceutically active agent is disposed in the well.
Abstract: Disclosed is a method and apparatus for delivering a drug formulation to a human eye. The method includes the steps of inserting the apparatus below the Tenon's capsule and above the sclera at a point posterior to the limbus of the eye and injecting the drug formulation to form a drug depot on an outer surface of the sclera. The apparatus includes a cannula having a distal portion, a proximal portion, and a bend separating the distal portion and the proximal portion. The distal portion has a radius of curvature substantially equal to a radius of curvature of the globe of the eye. A tangent of the distal portion at the bend is disposed at an angle no more than about 56 degrees with respect to the proximal portion.
