Months or years after the cataract operation, the remaining posterior lens capsule can become opaque and vision will be reduced in about 20–25% of eyes. [4] This is known as posterior capsule opacification (PCO). PCO is best treated by posterior capsulotomy using YAG laser. [4]
This means the area highlighted by the HeNe laser is not precisely the area being affected Nd:YAG laser, and therefore some surgical lasers have an added adjustment to compensate. [ 2 ] The first successful use of photodisruption was in 1972, on a case of trabecular meshwork. [ 1 ]
Nd:YAG laser has been abandoned due to risks of damaging the colon wall, fibrosis, stricture formation, and recto-vaginal fistula, and severe damage in case of accidents, as well as the cost. [11] The other two modalities were largely replaced by argon plasma coagulation by 2011, which is safer and less expensive. [11]
Nd:YAG lasers are used in ophthalmology to correct posterior capsular opacification, [6] after cataract surgery, for peripheral iridotomy in patients with chronic [7] and acute angle-closure glaucoma, [8] where it has largely superseded surgical iridectomy, [9] for the treatment of vitreous eye floaters, [10] for pan-retinal photocoagulation in ...
A novelty eye can cost anywhere from $2,500 to $5,500 -- about the same range as a regular prosthetic -- but they aren't covered by insurance. Andy recalls one patient who was determined to make a return on his investment: He asked . for an eye that featured the Nike swoosh.

A 40-watt CO 2 laser with applications in ENT, gynecology, dermatology, oral surgery, and podiatry. Laser medicine is the use of lasers in medical diagnosis, treatments, or therapies, such as laser photodynamic therapy, [1] photorejuvenation, and laser surgery. The word laser stands for "light amplification by stimulated emission of radiation". [2]
Cataract surgery is one of the most cost-effective health interventions, since its economic benefits considerably exceed the cost of treatment. [ 131 ] [ 132 ] The 1998 World Health Report estimated 19.34 million people were bilaterally blind due to age-related cataracts, and that cataracts were responsible for 43% of all cases of blindness.
