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for peripheral iridotomy in patients with chronic [7] and acute angle-closure glaucoma, [8] where it has largely superseded surgical iridectomy, [9] for the treatment of vitreous eye floaters, [10] for pan-retinal photocoagulation in ...
Laser vitreolysis is a possible treatment option for the removal of vitreous strands and opacities (floaters). In this procedure an ophthalmic laser (usually a yttrium aluminium garnet (YAG) laser) applies a series of nanosecond pulses of low-energy laser light to evaporate the vitreous opacities and to sever the vitreous strands. When ...
Treatment with Nd:YAG lasers and with Nd:YAG laser passed through a Potassium titanyl phosphate crystal, and with an argon laser has been studied in small clinical trials. [11] 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 ...
Floaters drift around your field of vision and dart away when you try to look at them directly, eventually settling at the bottom of your eye and out of your sightline. Floaters appear when the ...
However, the eye lens acts as a prism, so the infrared light bends at a shallower angle than the red light, causing chromatic aberration. 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]
Danièle Aron-Rosa (born 1934) is a French-Tunisian ophthalmologist and physician-scientist most known for developing the picosecond, ophthalmic Nd:YAG laser for eye surgeries. She has been called one of the two most respected laser pioneers in ophthalmology, alongside Franz Fankhauser.
There is no cure, but pigmentary glaucoma can be managed with eye drops or treated with simple surgeries. If caught early and monitored, chances of glaucoma are greatly reduced. A 2016 Cochrane Review sought to determine the effectiveness of YAG laser iridotomy versus no laser iridotomy for pigment dispersion syndrome and pigmentary glaucoma ...
Yttrium aluminium garnet laser (YAG laser) to correct posterior capsular opacification (specially after removal of a cataract, if required), peripheral iridotomy, retinal surgery, laser-assisted sub-epithelial keratectomy [4] etc. Electrolysis: used for permanent hair removal Electrocautery: for electrosurgery Phacoemulsification
