Nd:YAG laser
Nd:YAG lasers (1064nm)are used in ophthalmology to correct posterior capsular opacification, a complication of cataract surgery, and for peripheral iridotomy in patients with acute angle-closure glaucoma, where it has superseded surgical iridectomy. Frequency-doubled Nd:YAG lasers (wavelength 532 nm) are used for pan-retinal photocoagulation in patients with diabetic retinopathy.
