  2. Minimally invasive glaucoma surgery - Wikipedia

    en.wikipedia.org/wiki/Minimally_invasive...

    Micro-invasive glaucoma surgery (MIGS) is the latest advance in surgical treatment for glaucoma, which aims to reduce intraocular pressure by either increasing outflow of aqueous humor or reducing its production. MIGS comprises a group of surgical procedures which share common features. [1] MIGS procedures involve a minimally invasive approach ...

  3. Trabeculectomy - Wikipedia

    en.wikipedia.org/wiki/Trabeculectomy

    Trabeculectomy is the most common invasive glaucoma surgery. It is highly effective in the treatment of advanced glaucoma as demonstrated in major glaucoma studies. [citation needed] Even if a prior trabeculectomy has failed a second trabeculectomy can be performed at a different site. If scarring is the main reason, anti-fibrotic and anti ...

  4. Glaucoma surgery - Wikipedia

    en.wikipedia.org/wiki/Glaucoma_surgery

    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 ...

  5. Glaucoma valve - Wikipedia

    en.wikipedia.org/wiki/Glaucoma_valve

    The glaucoma valve implant is indicated for glaucoma patients not responding to maximal medical therapy, with previous failed guarded filtering surgery (trabeculectomy) or in cases where conventional drainage surgery is unlikely to succeed. Common situations where the use of a glaucoma implant as a primary procedure is indicated include.

  6. Intraocular lens - Wikipedia

    en.wikipedia.org/wiki/Intraocular_lens

    An intraocular lens (IOL) is a lens implanted in the eye usually as part of a treatment for cataracts or for correcting other vision problems such as short sightedness and long sightedness; a form of refractive surgery. If the natural lens is left in the eye, the IOL is known as phakic, otherwise it is a pseudophakic lens (or false lens).

  7. Trabecular meshwork - Wikipedia

    en.wikipedia.org/wiki/Trabecular_meshwork

    The trabecular meshwork is an area of tissue in the eye located around the base of the cornea, near the ciliary body, and is responsible for draining the aqueous humor from the eye via the anterior chamber (the chamber on the front of the eye covered by the cornea). The tissue is spongy and lined by trabeculocytes; it allows fluid to drain into ...

  8. Anterior chamber paracentesis - Wikipedia

    en.wikipedia.org/wiki/Anterior_chamber_paracentesis

    Anterior chamber paracentesis. Anterior chamber paracentesis (ACP) is a surgical procedure done to reduce intraocular pressure (IOP) of the eye. The procedure is used in management of glaucoma and uveitis. It is also used for clinical diagnosis of infectious uveitis.

  9. Fisheye lens - Wikipedia

    en.wikipedia.org/wiki/Fisheye_lens

    A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image. [4][5]: 145 Fisheye lenses achieve extremely wide angles of view, well beyond any rectilinear lens. Instead of producing images with straight lines of perspective (rectilinear images), fisheye lenses use ...
