  2. Multifocal intraocular lens - Wikipedia

    en.wikipedia.org/wiki/Multifocal_intraocular_lens

    People who have a multifocal intraocular lens after their cataract is removed may be less likely to need additional glasses compared with people who have standard monofocal lenses. [2] People receiving multifocal lenses may experience more visual problems, such as glare or haloes (rings around lights), than with monofocal lenses. [2]

  3. Intraocular lens - Wikipedia

    en.wikipedia.org/wiki/Intraocular_lens

    The intraocular lens did not find widespread acceptance in cataract surgery until the 1970s, when further developments in lens design and surgical techniques had come about. As of 2021, approximately four million cataract procedures take place annually in the U.S. and nearly 28 million worldwide, a large proportion in India.

    Composite optical/X-ray image of the Crab Nebula, showing synchrotron emission in the surrounding pulsar wind nebula, powered by injection of magnetic fields and particles from the central pulsar. The existence of neutron stars was first proposed by Walter Baade and Fritz Zwicky in 1934, when they argued that a small, dense star consisting ...

  6. Phakic intraocular lens - Wikipedia

    en.wikipedia.org/wiki/Phakic_intraocular_lens

    A phakic intraocular lens (PIOL) is an intraocular lens that is implanted surgically into the eye to correct refractive errors without removing the natural lens (also known as "phakos", hence the term). Intraocular lenses that are implanted into eyes after the eye's natural lens has been removed during cataract surgery are known as pseudophakic.

  7. History of cataract surgery - Wikipedia

    en.wikipedia.org/wiki/History_of_cataract_surgery

    Couching is the earliest-documented form of cataract surgery, and one of the oldest surgical procedures ever performed. In this technique, the lens is dislodged and pushed aside into the vitreous cavity, but not removed from the eye, thus removing the opacity from the visual axis, but also the ability to focus. [10]

    en.wikipedia.org/wiki/List_of_Neutron_stars

    Neutron stars can be classified as pulsars if they are magnetized, if they rotate, and if they emit beams of electromagnetic radiation out of their magnetic poles. [4] They may include soft gamma repeaters (SGR) and radio-quiet neutron stars , as well as pulsars such as radio pulsars , recycled pulsars , low mass X-ray pulsars, and accretion ...
