In 1991, shortly after the first laser to perform laser vision correction procedures in Canada was approved, LCA-Vision began applying its laser operating capability to the field of refractive eye surgery, particularly to Photorefractive Keratectomy (PRK), a procedure in which lasers are used to correct nearsightedness and other eye conditions.
As with other forms of refractive surgery, keratoconjunctivitis sicca, colloquially referred to as 'dry eye,' is the most common complication of PRK, and can be permanent. In more advanced cases, recurrent erosions occur during sleeping from adherence of the corneal epithelium to the upper eyelid with rapid eye movement .
The condition of posterior staphyloma in high myopia was first described by Scarpa in the 1800s. [6] Speculation about reinforcement of the eye began in the 19th century, when Rubin noted that sclera reinforcement “is probably the only one of all the surgical techniques [for myopia] which attempts to correct a cause, rather than an effect”. [7]
Clear lens extraction, also known as refractive lensectomy, custom lens replacement or refractive lens exchange is a surgical procedure in which clear lens of the human eye is removed. Unlike cataract surgery , where the cloudy lens is removed to treat a cataract , clear lens extraction is done to surgically correct refractive errors such as ...
Refractive surgery is an optional eye surgery used to improve the refractive state of the eye and decrease or eliminate dependency on glasses or contact lenses. This can include various methods of surgical remodeling of the cornea ( keratomileusis ), lens implantation or lens replacement.
Laser eye surgery or laser corneal surgery is a medical procedure that uses a laser to reshape the surface of the eye to correct myopia (short-sightedness), hypermetropia (long-sightedness), and astigmatism (uneven curvature of the eye's surface). Importantly, refractive surgery is not compatible with everyone, and people may find on occasion ...
The S.N. Fyodorov Eye Microsurgery Complex is a clinical and research ophthalmological center in Moscow, founded in 1988 by the Russian eye surgeon Svyatoslav Fyodorov. [1] The center also includes regional branches in Cheboksary, Irkutsk, Kaluga, Khabarovsk, Krasnodar, Novosibirsk, Orenburg, Saint Petersburg, Tambov, Volgograd, and Yekaterinburg.
Contoura Vision has resulted in vision outcomes better than 6/6 (or 20/20, the standardized normal vision) in multiple patients who were a part of validation trials by the US FDA.
