The method of extraction was via a LASIK-type flap in ReLEx FLEx, but in SMILE a flapless technique makes a small tunnel incision in the corneal periphery, that does not (mostly) destroy Bowman's layer. [4] One conspicuous difference between SMILE and LASIK is the size and shape of the corneal incision.
It involves excising a damaged section of cornea, and replacing it with a section (or "flap") of the patient's own conjunctiva. [ 1 ] It is named for Trygve Gundersen (1902 – February 24, 1987), an American ophthalmologist of Scandinavian descent, who first described the procedure in 1958 at the Massachusetts Eye and Ear Infirmary .
Osteo-odonto-keratoprosthesis (OOKP), also known as "tooth in eye" surgery, [1] is a medical procedure to restore vision in the most severe cases of corneal and ocular surface patients. It includes removal of a tooth from the patient or a donor.
Depending on the type of keratoprosthesis used, the surgery may involve a full thickness replacement of the cornea or the placement of an intralamellar implant. For the Alphacor a manual incision is used to create a corneal pocket and a punch is used to create an opening through the posterior cornea into the anterior chamber.
It is believed that additional thinning of the cornea via refractive surgery may contribute to advancement of the disease [31] that may lead to the need for a corneal transplant. Therefore, keratoconus is a contraindication to refractive surgery. Corneal topography and pachymetry are used to screen for abnormal corneas. Furthermore, some people ...
With PRK, the corneal epithelium is removed and discarded, allowing the cells to regenerate after the surgery. The procedure is distinct from LASIK (laser-assisted in-situ keratomileusis), a form of laser eye surgery where a permanent flap is created in the deeper layers of the cornea. However, PRK takes longer to heal and can, initially, cause ...
Thygeson's superficial punctate keratopathy (TSPK) is a disease of the eyes.The causes of TSPK are not currently known, but details of the disease were first published in the Journal of the American Medical Association in 1950 by American ophthalmologist Phillips Thygeson (1903–2002), after whom it is named.
The origins of British TV sitcoms trace back to radio comedies of the 1940s and 1950s like Hancock's Half Hour, which aired on BBC Radio in 1954, British TV sitcoms were initially inspired by American comedy formats, but they quickly developed their own style that highlighted dry wit, social satire, and the nuances of British life.
