Cataract surgery is the most common application of lens removal surgery, and is usually associated with lens replacement. It is used to remove the natural lens of the eye when it has developed a cataract, a cloudy area in the lens that causes visual impairment. [ 4][ 10] Cataracts usually develop slowly and can affect one or both eyes. [ 4]
During cataract surgery, the opaque natural crystalline lens is replaced with a synthetic intraocular lens (IOL). The IOL may be designed to filter out equal, more or less UV light than the natural lens (have a higher or lower cutoff), and therefore attenuate or accentuate the blue-light hazard function.
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 ...
Orientation varies with that of polarization of light source. Haidinger's brush, more commonly known as Haidinger's brushes is an image produced by the eye, an entoptic phenomenon, first described by Austrian physicist Wilhelm Karl von Haidinger in 1844. Haidinger saw it when he looked through various minerals that polarized light. [ 1][ 2]
In 1753, Samuel Sharp performed the first-recorded surgical removal of the entire lens and lens capsule, equivalent to what became known as intracapsular cataract extraction. The lens was removed from the eye through a limbal incision. [ 1] At the beginning of the 20th century, the standard surgical procedure was intracapsular cataract ...
Couching (ophthalmology) "Couching for cataract"; Wellcome Collection illustration of Indian doctors performing the technique. Couching is the earliest documented form of cataract surgery. It involves dislodging the lens of the eye, thus removing the cloudiness caused by the cataract. Couching was a precursor to modern cataract surgery and pars ...
