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 ...
Glaucoma is a group of diseases affecting the optic nerve that results in vision loss and is frequently characterized by raised intraocular pressure (IOP). There are many glaucoma surgeries, and variations or combinations of those surgeries, that facilitate the escape of excess aqueous humor from the eye to lower intraocular pressure, and a few that lower IOP by decreasing the production of ...
The femtosecond lenticule extraction (FLE then FLEx) procedure was first introduced at the American Academy of Ophthalmology Annual Meeting in 2006 by Walter Sekundo and Marcus Blum, and was first published in 2008 by Walter Sekundo et al. [7] [8] [9]
After two years researchers found that vision and quality of life are similar in both treatments. At the same time eye pressure was lower in people who underwent surgery and in the long-run surgery is more cost-effective. [114] [115] The LiGHT trial compared the effectiveness of eye drops and selective laser trabeculoplasty for open angle glaucoma.
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.
During the surgery, it has to be ensured that no carbon dioxide retention occurs. If this occurs, the choroid swells up and ocular contents may prolapse as soon as the eye is opened. The advantages of general anaesthesia is that it produces complete akinesia, controlled intraocular pressure and safe operating environment.
The lacrimal apparatus is the physiological system containing the orbital structures for tear production and drainage. [1]It consists of: The lacrimal gland, which secretes the tears, and its excretory ducts, which convey the fluid to the surface of the eye; it is a j-shaped serous gland located in lacrimal fossa.
On the day of the procedure, the patient will arrive to the hospital or laser center where the surgery is to be performed. After a brief physical examination, the patient will be taken to the operating room. General anesthesia or local anesthesia is given before the surgery begins. An eyelid speculum is used to keep the eye open throughout the ...
