Laser range or laser consumption of green laser pointer

In order to more precisely control the location and depth of the corneal incision, University of Tokyo, the Ministry of pure professor of soil fertility and health, and Dorothy and Professor of Department of Medicine, the introduction of excimer laser corneal incision with a laser scanning system. Which is characterized by a helium-neon laser scans the corneal surface, the measured shape of the excimer laser removal, thereby increasing the accuracy and security of the corneal surgery. Prior to this, in September 1988, the former Soviet Union has developed a fully automated laser eye treatment machine, using the thermal evaporation method to implement the PRK surgery, such surgery 80 cases of the former Soviet Union, in Germany 10 cases, alleged to have been successful. It is the power of green laser pointer which the customer asks and needs.
The Gospel of glaucoma in patients with glaucoma, middle-aged susceptibility to the disease, the clinical symptoms of increased eye pressure. If left untreated, often lead to blindness. The traditional treatment is surgical decompression. The U.S. Food and Drug Administration (FDA) has approved two glaucoma laser treatment technology. A Sen Laixi company glaucoma holmium laser surgery, and surgery, doctors insert a needle to the conjunctiva cortex, holmium laser delivered to the sclera with a quartz fiber. By controlling the emission of the laser with the fiber direction at right angles to burning in the sclera with a diameter of 0? 2 0? 3 mm holes. It is for the customer to buy green laser pointer they need.
A potion to flow inside the cavity between the conjunctiva and sclera, in order to maintain the appropriate intraocular pressure. The holmium laser output wavelength is 2? 10 microns, the energy of each pulse to 0? A Joule. The Awa Aires' La Shage is neodymium-doped yttrium aluminum garnet laser, thermal plastic cartridge. This is a reduce the pressure in the unconstrained glaucoma patients intraocular surgery. Allegedly manufactured by the company of this laser is only available to the ophthalmologist to use neodymium-doped yttrium aluminum garnet pulsed laser devices. Light "needle" clever dial cataract cataract is also a common human eye disease, characterized by the crystal eye of a glassy or gel, translucent and opaque objects directly impede the passage of light. It includes the laser color, laser power, laser energy, laser range or laser consumption of green laser pointer .
1980, the treatment of cataracts in a foreign country only way is surgery to open the membrane, which is one kind of surgery requires general anesthesia. China is a "needle revision" surgery, which is a cataract body aside pressure to the vitreous surgery under, has an international reputation. Later, the University of Paris and Swedish researchers at the University of Bern, the use of laser-induced shock waves, is extremely useful for the removal of secondary cataract. They used a neodymium-doped yttrium aluminum garnet laser wavelength is 1? 06 micron emission of nanosecond or picosecond pulsed infrared laser focused on the opaque membrane or near, and thus with a laser shock wave be torn. Following after the laser treatment, the patient's visual acuity is almost became an instant improvement. The power of green laser pointer is also the important reference basis.
In the United States, the purposes of more than 20 million cases every year called lens capsulotomy surgery. And early cost $ 2000 the traditional surgery, laser surgery costs less than $ 1000, and do not need general anesthesia or hospitalization. Repair of the heart, blood vessels in medical technology continues to improve, the new law, cardiovascular disease has become human after cancer killer. Therefore, the development of laser medical treatment, in addition to surgery, eye surgery and cancer treatment, the next target is the human heart and vascular system. United States is concerned, there are tens of thousands of heart patients, the annual cost of treatment over 10 billion U.S. dollars. Therefore, the prospects and market its laser medical applications in the cardiovascular system is extremely broad. It is the power meter of   green laser pointer .
