The present technology relates to an image processing device, a method of image processing, and a surgical microscope that can detect and report a dangerous condition on the basis of a tomographic image during eye surgery. An image processing device includes: a dangerous condition detection unit configured to detect a dangerous condition on the basis of a tomographic image of an eye acquired during surgery of the eye; and a control information generation unit configured to generate and output control information used to manage the detected dangerous condition. The present technology is applicable to, for example, a surgical system used for eye surgery or other surgical procedures.

A method for manufacturing an inner drainage biomimetic stent for glaucoma. The inner drainage biomimetic stent for glaucoma comprises: a cylinder tube body with a hollow structure, and a plurality of straight tubes, provided inside the hollow structure of the tube body, for supporting a tube wall of the tube body. Proper placement of the inner drainage biomimetic stent for glaucoma can direct an aqueous humour to smoothly flow through an orifice expanded by the biomimetic stent, into Schlemm's canal. A collapsed Schlemm's canal is re-expanded by the flow of the aqueous humour to direct the aqueous humour to a collector canal, thereby lowering an intraocular pressure and achieving the goal of glaucoma treatment

Systems, apparatuses, and methods of and for an ophthalmic surgical system are disclosed. An ophthalmic surgical system may include a vitrectomy probe having a housing sized and shaped for grasping by a user. The vitrectomy probe may also include a cutter extending from the housing and being sized to penetrate and treat a patient eye. The cutter may include an outer cutting tube coupled to the housing. The outer cutting tube may have an outer port formed therein that is sized and shaped to receive tissue. The cutter may include a rotatable inner cutting member disposed within the outer cutting tube. The inner cutting member may include a first cutting surface that rotates across the outer port to cut the tissue when the inner cutting member is rotated. The vitrectomy probe may include a pneumatic vane actuator positioned within the housing and configured to rotate the inner cutting member.

In one exemplary aspect, the present disclosure is directed to a system. The system includes a pneumatic surgical instrument and a surgical console operable to provide compressed gas to the pneumatic surgical instrument. Additionally, the system includes a pneumatic drive line coupling the pneumatic surgical instrument to the surgical console. The pneumatic drive line has an internal bore configured to deliver the compressed gas to the pneumatic surgical instrument. The internal bore has a non-uniform cross-section along a length of the pneumatic drive line.

Described here are systems and methods for accessing Schlemm’s canal and for delivering an ocular device or fluid composition therein. The ocular devices may maintain the patency of Schlemm’s canal without substantially interfering with transmural fluid flow across the canal. The fluid composition may be a viscoelastic fluid that is delivered into the canal to facilitate drainage of aqueous humor by disrupting the canal and surrounding trabeculocanalicular tissues. Tools for disrupting these tissues and minimally invasive methods for treating medical conditions associated with elevated intraocular pressure, including glaucoma, are also described.

Methods, systems, and compositions for maintaining functioning drainage blebs to reduce intraocular pressure (IOP) of an eye being treated for glaucoma. The methods, systems, and compositions feature the combination of a minimally invasive glaucoma surgery (MIGS) implant or procedure and the application of beta radiation to the bleb. The beta radiation can function to inhibit or reduce the inflammation and/or fibrogenesis that typically occurs after insertion of a MIGS implant and leads to bleb failure. By reducing inflammation and/or fibrogenesis, the MIGS implant and the blebs can remain functioning appropriately.
