Systems, methods, and devices used to treat eyelids, meibomian glands, ducts, and surrounding tissue are described herein. In some embodiments, an eye treatment device is disclosed, which includes a scleral shield positionable proximate an inner surface of an eyelid, the scleral shield being made of, or coated with, an energy-absorbing material activated by a light energy, and an energy transducer positionable outside of the eyelid, the energy transducer configured to provide light energy at one or more wavelengths, including a first wavelength selected to heat the energy-absorbing material. Wherein, when the eyelid is positioned between the energy transducer and the scleral shield, the light energy from the energy transducer and the heated energy-absorbing material of the scleral shield conductively heats a target tissue region sufficiently to melt meibum within meibomian glands located within or adjacent to the target tissue region.

Particular embodiments disclosed herein provide a membrane delamination device for delaminating a membrane from a retina of an eye. The membrane delamination device comprises an elastic component and a blade element at least partially covered by the elastic component. The blade element comprises a plurality of teeth. The blade element comprises a plurality of blades configured to cut connective tissues between the membrane and the retina. Each of the plurality of blades is positioned between two adjacent teeth of the plurality of teeth.

The present disclosure generally relates to a surgical instrument. The surgical instrument includes a base unit and a probe. The probe is disposed through an opening in a distal end of the base unit. The probe includes a port formed proximate to a distal tip of the probe. The distal tip includes a window, a lumen formed through the probe, and one or more optical fibers disposed in the lumen. The one or more optical fibers project a first laser light for irradiating an area proximate to the port to cut collagen fibers of vitreous material aspirated through the port. The one or more optical fibers further project a second laser light for cauterizing bleeding in an intraocular space of a patient.

Devices and methods are described for electrolytically, ultrasonically, or both electrolytically and ultrasonically disrupting debris on an eyelid margin. A device includes an eyelid contacting portion having at least a first electrode, a second electrode, and a power supply electrically coupled to at least one of the first and second electrodes. The eyelid contacting portion may optionally have a shelf separating an upper portion from a lower portion with electrodes on the upper and lower portions. The eyelid contacting portion may optionally include at least one channel with electrodes. The device may optionally include an ultrasonic driver. Another device includes an ultrasonic driver but no electrodes. A method contacts debris on an eyelid margin with a first electrode and contacting a surface of an eyelid with a second electrode and supplying electrical energy to one of the first or second electrodes to disrupt the debris. Another method applies ultrasonic energy to the eyelid margin to disrupt debris on the eyelid margin.

A corneal irrigation system, for removing a color pigment(s) from an intracorneal channel, includes a syringe, an irrigation device, and a flexible tube coupling the syringe to the irrigation device. The irrigation device includes a handle, having a distal end and a proximal end, that is coupled to the cannula. The handle also includes a lumen. The cannula includes (i) a shaft section having a first end that is coupled to the handle's proximal end, (ii) a curved section having a blunt tip, wherein an exterior surface of the curved section includes a rough-surface region, and (iii) a lumen having an opening in the rough-surface region, the lumen extending from the first end of the shaft section toward the blunt tip. The cannula's lumen is coupled to the handle's lumen.

Systems, apparatuses, and methods of and for an ophthalmic surgical system are disclosed. An example ophthalmic surgical system may include a body sized and shaped for grasping by a user. The body may include a lumen and a vent in fluid communication with the lumen. The vent may be located and arranged to be selectively occluded, such as when a user places a finger over the vent, and selectively unoccluded, such as when the user removes the finger from over the vent. Fluid pressure within the lumen may be increased when the vent is occluded and decreased when the vent is unoccluded. A piston within the may be displaced in response to the fluid pressure changes within the lumen.

An assembled blank may include a blank tip attached to a blank base, e.g., the blank tip may be welded to the blank base. The blank tip may be manufactured by modifying flat stock, e.g., tiers of blank tips may be manufactured by modifying tiers of flat stock. The blank tip may comprise a first forceps jaw, a second forceps jaw, and a blank tip aperture. The assembled blank may be disposed within a hypodermic tube and an actuation structure of a microsurgical instrument.
