Use Of Laser Image Of Medical & Engineering Application And Its Harmful Effect On Human Eye

Because laser light does not spread, the laser is ideal for precise surgical applications. The light produced is absorbed by tissue which, in turn, is consequently “harmed”. So it is important to take similar precautions when using the ESU when using lasers. Always check the power cords for frays, and check to make sure all switches are functioning properly. Also, make sure not to use any inflammable agents

Optical Drive: uses lasers to read or write data to/from optical discs like CDs or

Eye Vision Inc, a long-standing medical device manufacturer, has signed a contract to sell Holland Hospital the Clear View Laser and a two-year separately priced maintenance plan for $1 million and $0.2 million respectively. On a when-and-if available bais, Eye Vision Inc. will provide software updats that is embedded with the Laser to maintainance purchasor. The software has never been sold without Laser for its functional necessity. In this memo, as explained below, we conclude that:

The base of the light triangle, b, was measured first. Then, the light positions, a, were measured f=or the first order (m=1) and second order (m=2) light beams to determine the angle Ɵ for each. This data was organized in an Excel table and used to find the wavelength, λ, of the laser through Equation 1. This value was then compared to the theoretical value for wavelength of the laser, which was 6.328x〖10〗^(-7)m, and the percent error was calculated between the two.

An Excimer Laser is an extremely precise laser that uses ultraviolet light to remove minute amounts of corneal tissue. Each pulse of the laser removes mere microns of tissue, far less

The word laser is an acronym for, “Light Amplified by Stimulated Emissions of Radiation”, this means that all the lights in a laser have the same wavelength. Within a century of the laser being invented it occupied a major role in scientific research, medicine, industry, and even daily life. Lasers are used in the medicine field for procedures such as, laser eye surgery, heart, stomach, and intestinal surgeries. These procedures laser procedures are said to be harmless. Major factory industries use lasers to cut many things ranging from thin

New addition to the NIDEK family of Lasers – The new The GYC-500 Vixi has 22 preprogrammed scan patterns to allow treatment of various retinal pathologies, enhancing treatment efficiency and reducing patient chair time.

Not many people know what a “Laserphaco probe” is. It sounds as if it was from a science fiction movie, but it is not. It was invented by Patricia Bath. It was made to remove cataracts. Her early life was hard, mainly because she lived through segregation.

By using laser treatment it can delay the use of daily eye drops. Laser treatment is use to clear or open up the drainage canals that are lowering the movement of fluid in the eye. By clearing it up the eye pressure is lowered stoping the damage being caused to the optic nerve. Yet the effect of laser treatment is not permeant and the patient will eventually need to use eye drops.

The part of the eye responsible for refracting light in a way that allows an image to be created on your retina is the cornea. However, any imperfections in the shape of the cornea can cause blurry images to be created. LASIK surgery is a procedure that uses a laser to remove some of the corneal tissue, reshape the eye, and permanently fix these imperfections.

Lasers in the classes IIIa and IIIb are capable of causing damage to the eye when a laser in one of these classes is directly exposed to a person’s eye, or in some cases, when reflecting off of a smooth surface. Class IIIa lasers have a power output of less than 5 mW, whereas class IIIb lasers can have a power output between 5 and 500 mW, and thus high-power class IIIb lasers can be a fire hazard and cause minor burns to the skin.

The patient was brought to the operating room, and tetracaine was instilled in the operative eye. The patient was then docked with the LenSX Femtosecond laser. My preestablished protocol for the operative eye was administered with the laser, creating the primary incision, the side port incision, the capsulorrhexis, the nuclear grooves, and toric mark. The operative eye was then anesthetized with lidocaine given in a peribulbar fashion. The eye was then prepped and draped in usual sterile fashion. The previously created incisions were opened using a Slade spatula. The capsulorrhexis was inspected and found to be suitable. Gentle hydrodissection was then performed. Using the phacoemulsification handpiece and a Drysdale nucleus manipulator,

Lasers treatments work by producing heat when interaction with the skin takes place. A quite high beam of light is passed through the skin at the dermal level which makes it quite hot and stimulates the cells which produce elastin& collagen. The laser is also targeted to coloured lesions such as broken blood

In the class, it has been stressed that there is an importance to lower the radiation dose to the patient. It is important to lower the dose of radiation because it reduces the chance of radiation induced complications. It is the one of the priorities of a radiographer to reduce the radiation dose to the patient. This article was informative of another way to reduce the dose to the patient. Radiation dose for all patients should be reduced as much as possible because radiation does have harmful effects and should be limited throughout a year. The project was done to “determine if having a laser targeting system would decrease the radiation dose by eliminating unintentional radiation prior to localizing the region of interest” (Schenk & Johnston p. 39). The idea behind laser targeting was to limit and reduce the time it took to do the procedure, by reducing time exposed to radiation it lowers the dose to the patient. The laser “aids the technologist in properly aligning the c-arm in the desired position without exposing the patient to radiation” (Schenk & Johnston p. 42). Before the radiation dose was higher because the part of interest was located while radiation was occurring. Now to know that the laser can locate the part of interest before exposing the patient to radiation will help allow me to reduce patient dose if there is a laser with that particular fluoroscopic machine. Even though this experiment was done using pediatric patients, it is relevant information for adult patients as well because it is important to lower radiation dose regardless of age. This information will be helpful in the future because fluoroscopy is a common procedure and if there is a laser available on the machine, it should be utilized so radiographers and students can help reduce the radiation dose to that patient especially, now that it was found to have some effect on

"Star Wars," "Star Trek," "Battlestar Galactica" are some of fiction movies that implement laser technology in it. LASER is an acronym for Light Amplification by Stimulated Emission of Radiation. Generally, it is a device that control the way for energized atom released their photon. As we go deep into the words of ‘LASER’, it actually generates an intense beam of coherent monochromatic light (or other electromagnetic radiation) by stimulated emission of photons from excited atoms or molecules. Laser light is totally different from the other light that exist in this Earth. There are few properties that make them up as a laser. First and foremost, it is monochromatic, which means the light released contain one specific wavelength of light due
