Serrated forceps

A forceps comprising a first jaw and a second jaw arranged along a longitudinal axis of the forceps for relative movement toward and away from one another. The first and second forceps jaws have respective first and second jaw surfaces facing each other. The first and second jaw surfaces have a serrated surface texture at least on a distal part thereof. A serration direction of the serrated surface texture is at an angle which is non-perpendicular to the longitudinal axis, resulting in additional profile structure elements at a tip portion surface, allowing to handle and manipulate fine tissue materials such as membranes in an eye.

REFRACTIVE TREATMENT OF AN EYE BY PRINTING MATERIAL ONTO A TARGET
20190240070 · 2019-08-08 ·

In certain embodiments, a system for performing refractive treatment of an eye comprises a laser, a printer, and a computer. The laser emits a laser beam to prepare the eye for the refractive treatment. The printer prints material onto a print area of a target. The printer comprises a printer head and a printer controller. The printer head directs the material onto the print area, and the printer controller moves the printer head to direct the material onto a specific location of the print area. The computer comprises a memory and processors. The memory stores instructions for a pattern for the target. The pattern is designed to provide the refractive treatment for the eye. The processors instruct the printer controller to move the printer head to print the material onto the print area according to the pattern.

INSTRUMENT FOR TREATING AN OCULAR DISORDER
20190209373 · 2019-07-11 ·

An instrument for removing debris from an eye during the treatment of an ocular disorder has a swab and a rigid member. The swab includes a tip portion sized to provide access to the debris on an eyelid of the eye. The rigid member has a distal end portion affixed to the swab and a proximal end portion with a cross-sectional member profile. The cross-sectional member profile is non-circular and has a first groove. The first groove extends longitudinally along the proximal end portion for cooperating with a chuck such that rotation of the proximal end portion within the chuck is inhibited.

BOARD-LIKE FORCEPS FOR OPHTHALMIC USE
20190209370 · 2019-07-11 ·

Board-like forceps for ophthalmic use comprise forceps handles and forceps boards. The forceps handles comprise an upper forceps handle (1) and a lower forceps handle (2), two ends of which are connected to form a V-type structure. The length of the lower forceps handle (2) is greater than that of the upper forceps handle (1). An upper forceps board (3) and a lower forceps board (4) having a same shape are correspondingly disposed on unconnected ends of the upper forceps handle (1) and the lower forceps handle (2), and are bent in a same side direction. An included angle formed by the upper forceps board (3) and the upper forceps handle (1) is smaller than an included angle formed by the lower forceps board (4) and the lower forceps handle (2).

Methods for intraocular shunt placement

Intraocular pressure can be reduced by insertion of an intraocular shunt in the eye such that it forms a drainage pathway between the anterior chamber and a region of lower pressure. A hollow shaft that holds an intraocular shunt can be advanced through the anterior chamber. The sclera can be penetrated with the hollow shaft. A beveled tip of the shaft can be oriented such that a beveled surface thereof faces toward the Tenon's capsule when the beveled tip passes out of the sclera. After the beveled tip passes out of the sclera, at least a portion of the shunt can be advanced from the hollow shaft.

OPTHALMIC MICROSURGICAL INSTRUMENT
20190110925 · 2019-04-18 ·

In some embodiments, a microsurgical instrument includes a trocar having a rigid, hollow shaft formed with a lumen extending from a proximal end to a distal end of the shaft. The distal end of the shaft may be shaped for tissue penetration. The instrument may further include a composite microcannula slidably engaged with the trocar in the lumen. The microcannula includes a light guide and a flexible hollow tube having an outer diameter less than an inner diameter of the lumen in the trocar. Other embodiments include placing the microcannula in the lumen of the trocar, illuminating the end of the trocar by illuminating the end of the microcannula, advancing the trocar from a selected entry point on an eye into a selected structure in the eye, and extending the illuminated end of the microcannula from the trocar into the selected structure.

FLEXIBLE/EXPANDABLE PHACOEMULSIFICATION TIP
20190083310 · 2019-03-21 ·

A phacoemulsification cutting tip, including a rigid tubular portion and a flexible and expandable tip portion located distal to the rigid tubular portion. The flexible and expandable tip portion presents an axial length and an unexpanded radius and is formed such that the axial length shortens while the unexpanded radius increases when differential pressure due to an occlusion of an opening of the flexible tip portion exists.

ASPIRATING CUTTER AND METHOD TO USE
20190038460 · 2019-02-07 ·

An ophthalmic surgical cutting apparatus for cutting biological material including a handle, an outer tube attached to the handle and having a closed tip, a port formed in a side wall of the outer tube with a cusp formed by two or more intersecting surfaces, and an inner tube slidable within the outer tube and having a longitudinal axis and an open tip. The inner tube is in fluid communication with the handle, and the cusp of the port and the open tip interface during a cutting motion to fracture and cut biological materials and direct cut materials radially inward into the port.

Modular intraocular lens designs, tools and methods

Modular IOL removal systems and methods that cut an optic portion of an intraocular in a single motion such to facilitate removal of the optic portion from an eye through an incision, for example a corneal incision, without increasing the size of the corneal incision. Various cutting tools having one or more blades may be utilized. The cut intraocular lens may have one continuous cut or be cut into multiple smaller pieces. The single cutting step may apply balanced forces and torque to avoid damaging the surrounding eye anatomy, reducing the risk of trauma.

Meibomian gland intraductal diagnostic and treatment methods
10159599 · 2018-12-25 · ·

A method is provided for treating a meibomian gland of an eyelid of a patient. In a particular embodiment, an obstruction in a meibomian gland and the orifice thereof can be alleviated; in another, a substance can be injected thereinto; in yet another, the gland can be aspirated. The method includes the step of inserting an elongated probe into a meibomian gland via an orifice thereinto. In some embodiments the probe can have a longitudinal lumen therethrough, with at least one distal hole through the probe wall in fluid communication with the lumen. The lumen can be used in concert with a source of suction for removing debris from the meibomian gland, and/or with a source of a fluid and pumping means, for injecting a substance into the meibomian gland.
