Surgical blade for use with a surgical tool for making incisions for scleral eye implants

A surgical blade is disclosed for use with a surgical tool for making incisions in the sclera of an eye to form a scleral pocket to receive a scleral prosthesis. The surgical blade comprises a rotatable support arm capable of being rotated by the surgical tool and a detachable curved cutting blade for making incisions in the sclera of an eye. The surgical tool causes the curved cutting blade to advance through the sclera to form an incision having dimensions to receive a scleral prosthesis. When the incision is complete the curved cutting blade is detached from the rotatable support arm. The curved cutting blade is then removed from the incision by pulling the curved cutting blade forward out of the incision. The incision has the exact dimensions to receive a scleral prosthesis.

Process for manufacturing intraocular lenses with blue light absorption characteristics

A process for producing intraocular lenses (IOLs) capable of absorbing blue light and ultraviolet light using photo curing. Intraocular lenses so produced block blue light and ultraviolet light from reaching the retina of an eye implanted with the IOL. By blocking blue light and ultraviolet light from reaching the retina, the IOL thereby prevents potential damage to the retina.

System and method for making incisions for scleral eye implants

A system and method is disclosed for making incisions in the sclera of an eye to form a scleral pocket to receive a scleral prosthesis. The system and method comprises a surgical tool comprising a surgical blade for making incisions in the sclera of an eye. When a surgeon places the surgical blade on the sclera of the eye a pressure sensor in the surgical tool determines whether there is sufficient pressure between the surgical tool and the sclera of the eye for the surgical tool to operate properly. The surgeon activates the surgical tool to cause the surgical blade to advance through the sclera to form an incision having dimensions to receive a scleral prosthesis. When the incision is complete the surgical blade is rotated back out of the incision. The incision has the exact dimensions to receive a scleral prosthesis.

Eye implant devices and method and device for implanting such devices for treatment of glaucoma

The present invention provides a method of relieving intraocular pressure by inserting a drainage device into the sclera near the trabecular meshwork from a remote location. The path of insertion is made from a corneal incision and avoids contact with the conjunctiva and tenons tissue. The drainage device comprises a tube like structure and may contain a barb at one end to secure the drainage device. A delivery device may be used to insert the drainage device. The delivery device may be inserted through a corneal incision and directed to the desired area for insertion in to the sclera. The delivery device may then be activated to shoot the drainage device into the sclera to promote increased drainage of aqueous humor and reduce the build up of intraocular pressure.

Method for preparation of cross-linking hyaluronic acid sodium jelly glue implanted in eyes

The present invention relates to preparation process of cross-linked sodium hyaluronate gel as eye implant. The process of preparing the cross-linked sodium hyaluronate gel includes the following steps: pouring the reactant liquid comprising sodium hyaluronate, hydrazide compound, carbodiimide as carboxyl group activator and proper buffer into the gap between two plates to form gel in certain thickness; purifying; cutting; packing and sterilizing. The cross-linked sodium hyaluronate gel is used as eye implant, especially for the non-penetrating glaucoma treating operation, to prevent adhesion of the aqueous humor filtering passage, raise the filtering effect and control the post-operational intraocular pressure.
