It includes removal of a tooth from the patient or a donor. [2] After removal, a longitudinal lamina is cut from the tooth and a hole is drilled perpendicular to the lamina. The hole is then fitted with a cylindrical lens. The lamina is grown in the patients' cheek for a period of months and then is implanted upon the eye.
•Intraocular lens: prosthetic lenses implanted after lens (anatomy) removal •Artificial eyes: as non-functional cosmetic implants into the eye socket Blade breaker: to break disposable blade after use to prevent reuse Thermo-cautery: to coagulate blood vessels and prevent haemorrhage: Cryoprobe: to freeze and extract the lens
Unlike a routine dental cleaning, the techniques used in a deep cleaning get below the gum line to remove bacteria stuck there. The procedure, which involves local anesthetic to temporarily numb ...
In dentistry, debridement refers to the removal by dental cleaning of accumulations of plaque and calculus (tartar) in order to maintain dental health. [1] Debridement may be performed using ultrasonic instruments, which fracture the calculus, thereby facilitating its removal, as well as hand tools, including periodontal scaler and curettes, or through the use of chemicals such as hydrogen ...
Posterior capsular rupture, a tear in the posterior capsule of the natural lens, is the most-common complication during cataract surgery. [8] Posterior capsule rupture can cause lens fragments to be retained, corneal oedema, and cystoid macular oedema ; it is also associated with increased risk of endophthalmitis and retinal detachment.
The scleral edge of the trepanation opening is heat-cauterized. [8] Additional deep scleral dissection can also be performed in the scleral bed with trabeculectomy, first introduced by T. Dada et al.; [9] deep scleral excision is performed in non-penetrating filtering surgeries but not traditionally in trabeculectomy. The space created from the ...
