Ophthalmic treatment systems and methods of using the systems are disclosed. The ophthalmic treatment systems include (a) a light source device; (b) at least one optical treatment head operatively coupled to the light source device, comprising a light source array, and providing at least one treatment light; and (c) a light control device, which (i) provides patterned or discontinuous treatment light projection onto an eye (e.g., the cornea and/or sclera of an eye); or (ii) adjusts intensity of part or all of the light source array, providing adjusted intensity treatment light projection onto an eye (e.g., the cornea and/or sclera of an eye). The at least one treatment light promotes corneal and/or scleral collagen cross-linking.

A drug delivery implant and a method of using the same are disclosed herein. In one or more embodiments, the method includes forming a pocket in the cornea of the eye to gain access to tissue surrounding the pocket; applying a photosensitizer inside the pocket so the photosensitizer permeates at least a portion of the tissue surrounding the pocket and facilitates cross-linking of the tissue surrounding the pocket; irradiating the cornea to activate cross-linkers in the portion of the tissue surrounding the pocket, and thereby stiffen a wall of the pocket and kill cells in the portion of the tissue surrounding the pocket; and before or after the portion of the tissue surrounding the pocket has been stiffened and is devoid of cellular elements by the activation of the cross-linkers, inserting a corneal drug delivery implant into the pocket configured to release one or more medications into the eye.

A surgical instrument for marking spots at locations on the scleral limbal surface of a human eye. The instrument includes an elongated handle dimension to be handheld. A first elongated pointer extends substantially axially outwardly from one end of the handle. This pointer has a pointed free end which, when pressed against the scleral limbal surface, creates a depression in the scleral surface having a first area. A second elongated pointer also extends substantially axially outwardly from the end of the handle. The second pointer has a blunt free end which, when pressed against the scleral limbal surface, creates a depression in the scleral surface having a second area which is several times in magnitude the area of the first area.

A surgical knife safety device having a handle, a blade connected to the handle, and a guard carried by the handle for sliding movement between a retracted position in which the blade is exposed for use, and an extended position for covering the sharp cutting edge of the blade. In the retracted position, an enlarged guard radius is provided at the distal end of the handle to allow improved handle control and blade orientation. The enlarged guard radius is positioned to allow the user to firmly grip a large distal handle portion which is preferably molded as a single piece with the blade holder, preventing unwanted blade or handle movement due to guard mechanism tolerances.

A device comprising: an elongated head having a distal end formed by an elongated edge of a cutting blade positioned in parallel with an elongated edge of a control blade, wherein the elongated edges of the respective control and cutting blades are separated by a uniform gap forming the distal opening to a channel running from an anterior end to a posterior end of the head, wherein the elongated edge of the cutting blade extends distally beyond the elongated edge of the control blade providing a height differential between the edge of the cutting blade and the edge of the control blade, wherein the edge of the cutting blade is sharp and configured to cut a bodily tissue, and wherein the edge of the control blade is dull and forms a barrier that limits the depth of penetration of the edge of the cutting blade into the bodily tissue.

The disclosure relates to the use of contact lenses for treating ophthalmologic conditions, such as presbyopia, induced myopia, computer vision syndrome, insufficient accommodation, or a condition associated with insufficient accommodation. The contact lens may be selected based on a measured sagittal depth and/or eccentricity of the cornea. When fitted, fluid may accumulate between the cornea of the eye and the contact lens The lens may exhibit a sufficient amount of apical clearance such that when the wearer blinks, the lens moves no more than 1 mm on the eye. The lens may be structured such that bubbles greater than 0.5 mm in diameter are prevented from forming between the contact lens and the eye. The contact lens may be used in combination with a suitable bioactive agent providing for enhanced visual correction.
