What Is The Difference Between Yag And Lasik Surgery
Unusual,flap no flap: Many potential complications but the most serious are very unusual. Usually temporary side effects are glare, halos, light sensitivity, dry eye. A more complete list of possibilities for each procedure can be found at your eye surgeon's office. Ek removes the outer layer of the cornea without a flap, and ik goes below the surface to create a flap. ...Read moreSee 3 more doctor answers
Target: Nd:yag is a type of laser that targets primarily water. It is excellent for larger veins and can also be used for laser hair removal, skin tightening, acne and tattoos (when q-switched). Erbium:yag also primarily targets water but it vaporizes the skin and is used for laser skin resurfacing. Essentially it is the wavelength of light the laser produces that determines what it will work on. ...Read more
Yes: As i mentioned before there are over 20 ways of performing laser vision corrective techniques among close to 40 vision corrective procedures to help people see without glasses and contact lenses. The term laser eye surgery includes lasik as one among them. All laser vision surgeries re-shape the cornea to help correct the refractive error. Lasik in particular involves making a flap. ...Read moreSee 4 more doctor answers
Goals differ: LASIK (and also PRK) use a specific type of laser to sculpt a new lens power for the eye. These eliminate the need for eyeglasses or contacts. laser eye surgery is a general term which includes LASIK but indicates any use of laser to treat various eye problems like glaucoma, diabetic retinopathy and some other conditions. They are both aspects of the use of lasers for eye treatment. ...Read moreSee 1 more doctor answer
Oval eye shape: Refractive errors require either plus (farsighted) or minus (nearsighted) glasses + an extra amount if the eye is oval in shape (astigmatism). These are called refractive errors and can be corrected with glasses or contacts. Short sightedness is another term for myopia which uncorrected usually allows for good vision at near and blur at distance. ...Read more
Keratoconus is: progressive disease of the cornea in which the normally dome shaped cornea thins and begins to bulge into a cone-like shape. This condition needs to be monitored and possibly treated to prevent long term visual disability. Astigmatism is a refractive error, therefore it is not an eye disease it is an error in the focusing ability. Astigmatism is treated simply with glasses, contacts or surgery. ...Read moreSee 2 more doctor answers
TURP vs laser TUVP: Main differences occur with the surgeon's experience. Both procedures (mandated by insurers) must be scheduled/performed on an "outpt" basis, and may leave you with a foley catheter for ~ 1 week. Reports suggest longer post-operative discomfort following laser tuvp. Also, no tissue is typically obtained for review with a laser procedure, unless the surgeon is performing a laser "resection.". ...Read moreSee 1 more doctor answer
Terminology: In strabismus the eyes present 2 different images to the brain which would result in a double image. Over time the brain may turn off one of the images & keep the best one. In stereopsis the eyes present the same image to the brain separated by the distance between the eyes. This allows you to have depth perception. ...Read moreSee 2 more doctor answers
Wavelength of light: Medical lasers work by using electrical energy to excite a "laser medium". The laser medium can be a natural or synthetic substance such as a gas (e.g. Argon), a liquid or a solid (e.g. Yag) . When excited by electricity these substances give off light energy of a unique wavelenth. Some wavelengths of light heat tissue, while others are absorbed by colored molecules such as melanin or hemaglobin. ...Read moreSee 1 more doctor answer
Laser liposuction: Laser lipolysis can be done in conjuction with tumescent aspiration liposuction (removal of the fat after laser treats the fat). Laser lipolysis is attempted through the skin without much success but has been done via cannula through the skin and introduced in the fat before tumescent liposuction. ...Read moreSee 6 more doctor answers
a few items: While most lasik works well with excellent results a few do not match the target and may need a little extra called an enhancement. Lasik will not correct presbyopia, the need for near correction past age 40. Lasik might induce some degree of eye dryness which requires lubricating drops. Other issues are very rare ...Read moreSee 2 more doctor answers
