Precision Pulse Capsulotomy is a non laser capsulotomy procedure performed using a device with a soft collapsible tip and circular Nitinol cutting element that is connected to a control console. The Nitinol tip can be collapsed sufficiently to pass through an incision of about 2.2 mm, after which it springs back into circular shape inside the ...
The technique is most commonly used for lithotripsy of urinary calculi and the treatment of posterior capsulotomy of the lens. [3] When used in corneal surgery, picosecond and nanosecond disruptors are used on the lamellae of the corneal stroma, and the method may be preferable as it leaves the epithelium and Bowman's layer unharmed. This ...
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for peripheral iridotomy in patients with chronic [7] and acute angle-closure glaucoma, [8] where it has largely superseded surgical iridectomy, [9] for the treatment of vitreous eye floaters, [10] for pan-retinal photocoagulation in ...
Early symptoms of cataract may be improved by wearing appropriate glasses; if this does not help, cataract surgery is the only effective treatment. [4] Surgery with implants generally results in better vision and an improved quality of life: however, the procedure is not readily available in many countries. [4] [11] [12] [13]
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 ...
Capsulorhexis or capsulorrhexis, and the commonly used technique known as continuous curvilinear capsulorhexis (CCC), is a surgical technique used to remove the central anterior part of the capsule of the lens [1] from the eye during cataract surgery by shear and tensile forces.
An Ohio hospital successfully performed its first in utero fetal surgery to repair a birth defect in a nearly 23-week-old fetus, making it one of few elite medical facilities in the U.S. capable ...
Yttrium aluminium garnet (YAG, Y 3 Al 5 O 12) is a synthetic crystalline material of the garnet group. It is a cubic yttrium aluminium oxide phase, with other examples being YAlO 3 (YAP [2]) in a hexagonal or an orthorhombic, perovskite-like form, and the monoclinic Y 4 Al 2 O 9 (YAM [3]).
