The present invention relates to an ophthalmic ultrasonic emulsification sleeve for confirming intraocular and extraocular penetration and perfusion, which allows determining whether aqueous humor communication between the inside and outside of the eye is smooth through a microtube implanted in the eye during glaucoma tube surgery. The sleeve is characterized by having a rigid branch tube made of a material harder than a sleeve made of a soft material, provided in a perfusion port that allows the injection of a balance salt solution into the eye, and with the branch tube connected to the perfusion port, the tip of the branch tube protrudes further than the tip of the Paco tip, and the end of the microtube inside the eye is connected to the tip of the branch tube, so that the establishment of aqueous humor communication of the microtube can be quickly and accurately and sensorially confirmed based on the pattern of pressure change in the conjunctival area and surrounding blood flow change that occurs when the balance salt solution leaks out of the eye.

The present disclosure generally relates to systems and methods for laser power measurement, and more particularly, systems and methods for laser power measurement in a sterile operating environment. In certain embodiments described herein, power measurement is performed utilizing two laser sources: 1) a first laser source configured to generate a first laser beam (treatment laser); and 2) a second laser source configured to generate a second laser beam (test laser). The first laser beam generates a bubble in a test material (e.g., water, saline, balanced salt solution, gel, etc.) and the second laser beam is reflected back with the reflected portion of the second laser beam being measured to determine a lifetime of the bubble and correlate the lifetime measurement with a power measurement based on a correlation curve.

[0001] The present disclosure relates generally to systems and methods for laser power measurement, and more particularly, to systems and methods for laser power measurement in a sterile working environment. In certain embodiments described herein, power measurements are made utilizing two laser sources: 1) a first laser source configured to generate a first laser beam (a treatment laser), and 2) a second laser source configured to generate a second laser beam (a test laser). The first laser beam generates gas bubbles in a test material (e.g., water, saline, balanced salt solution, gel, etc.), and the second laser beam is reflected back, and the reflected portion of the second laser beam is measured to determine the bubble lifetime, and the lifetime measurements are correlated with power measurements based on a correlation curve.

A tear-fluid insoluble, ocular insert adapted for insertion into the eye of a subject, which is a mammal, for the sustained release of an agent selected from a therapeutic agent, a balanced salt solution, and a mixture thereof, wherein the insert comprises a bacterial cellulose hydrogel and an aqueous solution comprising the therapeutic agent and / or balanced saline solution.
