Cataract surgery

   The early technics to remove cataracts laid down, which involved fine needle or pencil use to remove turbidity. This technics, as is known, existed during Roman times and has prolonged to be used everywhere on the Middle Ages and prolongs to be used in the deprived countries "Third world" today. In India, however, the up-to-date surgery with an intraocular parenthesizing of a lens in the Government and Not the Governmental Organization sponsored Eye Surgical Camp (the non-governmental organization) have completely exchanged this method.

  Cataract surgery - excision of a lens of an eye which has developed a cataract. The natural lens then is exchanged by an artificial intraocular lens. It is one of the most safe and most successful procedures in all medicine.

  Two main types of excision of a cataract - intrakapsuljarnoe cataract excision (ICCE) and extracapsular excision of a cataract (HERE).

  Extracapsular excision of a cataract involves lens excision, while an elastic capsule of a lens leave partially intact to allow implantation of an intraocular lens.

  There are two main types of extracapsular surgery: usual HERE and phacoemulsification.

  Usual extracapsular excision of a cataract involves a manual expression of a lens through a slit made in a cornea or a sclera. Though it demands a larger slit and use of stitches, the usual method is underlined for patients with very firm cataracts or a weak corneal epithelial tissue. Phacoemulsification involves use of a hyperacoustic vibrating handpiece to be blasted and break a cataract, thus facilitating to delete. As the smaller slit is required, few or any stitches are necessary, and the restoring time of the patient is usually shorter.

  Intrakapsuljarnoe cataract excision involves excision of a lens and an environmental capsule of a lens in one part. The lens then is exchanged by a plastic lens (an intraocular implant of a lens) which remains for a long time in an eye. Procedure has rather high norm of complications because of a major demanded slit, and the pressure placed in a vitreous, thus is seldom carried out in the countries where operative microscopes and the hi-tech equipment with readiness are accessible. A cryoextraction - shape ICCE which freezes a lens with cryogenic substance, such as liquid nitrogen. Though it is used now first of all for excision podvyvihnuvshih lenses, it was the exclusive shape of excision of a cataract from the extremity of 1960 to the beginning of 1980.

  The capsulotomia seldom known as a section of a capsule of a lens, is procedure to unclose a part of a capsule of a lens. The previous capsulotomia is converted to opening of a part of the forward side of a capsule of a lens whereas the back capsulotomia is converted to opening of a return part of a capsule of a lens. In extracapsular surgery the surgeon carries out a previous capsulotomia, or capsulorhexis, to frame opening through which the lens kern can be removed, and the intraocular implant of a lens is interposed. Turbidity or turbidity of a back capsule of a lens often meet in who had an extracapsular procedure of excision of a cataract, therefore, a laser back capsulotomia, or laser capsulotomia YAG, is used to strip a return surface of an implant. (Regarding, that a capsulotomia - opening making in a lens capsule, capsulectomy - acutal excision of a short tissue of a lens).

  Cataract activities are mainly carried out under local sedative, and to the patient will allow to go home the same day. Complications after cataract surgery are rare. Many people (to 50 %) can develop back capsular turbidity after initial surgery of a cataract. It is a thickening and turbidity of a capsule of a lens (which has been left behind when the cataract has been removed), and it can be easily corrected, using the laser to make holes in a capsule for the person to go through. Retina amotio - rare complication of surgery of a cataract.

  Earlier, polymethylmethacrylate it was used as a lens material. Successes have caused use of an acrylate of silicone which is the soft material. It allows a lens to be curtailed and interposed into an eye through a smaller slit. Acrylic artificial lenses can be used also with small slits and are the best select in people who have history of a uveitis or are at high hazard of amotio of a retina. Acrylic not always an ideal select because of its added rate of flux.

  The enunciating was the early shape of surgery of a cataract, in which small examination has been interposed into an eye to repel a lens in the back cabinet.
