What are the techniques for laser treatment of glaucoma?

Glaucoma is a disease that middle-aged people are prone to, and its clinical symptom is increased eyeball pressure. If not treated in time, it will often lead to blindness. The traditional treatment is surgical incision and decompression.

The US Food and Drug Administration has approved two technologies to treat glaucoma with laser.

One is holmium laser from Sunray Technology Company to treat glaucoma. During the operation, the doctor inserted the needle into the conjunctival cortex and used the timely optical fiber to transmit the holmium laser to the sclera. By controlling, the emitted laser is at right angles to the fiber direction, and a small hole with a diameter of 0.2 ~ 0.3 mm is burned on the sclera. Let the drug flow into the cavity between conjunctiva and sclera to maintain proper intraocular pressure. The output wavelength of this holmium laser is 2. 10 micron, and the energy of each pulse is 0. 1 joule.

Lashag Company in Annapolis uses Nd: YAG laser to thermoform small cylinders. This is an operation to reduce the intraocular pressure of patients with unconstrained glaucoma. It is said that the laser produced by this company is the only Nd-doped YAG pulse laser device available to ophthalmologists.
