    Cataract surgery and IOL implantation have the safest and highest success rates of any eye care-related procedures. As with any type of surgery, however, some level of risk remains. [7] Most complications of cataract surgery do not result in long-term visual impairment, but some severe complications can lead to irreversible blindness. [92]

    en.wikipedia.org/wiki/Manual_small_incision...

    Manual small incision cataract surgery (MSICS) is an evolution of extracapsular cataract extraction (ECCE); the lens is removed from the eye through a self-sealing scleral tunnel wound. A well-constructed scleral tunnel is held closed by internal pressure, is watertight, and does not require suturing.

    en.wikipedia.org/wiki/Phacoemulsification

    Phacoemulsification is a cataract surgery method in which the internal lens of the eye which has developed a cataract is emulsified with the tip of an ultrasonic handpiece and aspirated from the eye. Aspirated fluids are replaced with irrigation of balanced salt solution to maintain the volume of the anterior chamber during the procedure.

    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.

  8. 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 ]

    ISTCs are often co-located with NHS hospitals. They perform common elective (i.e. non-emergency) surgery and diagnostic procedures and tests. Typically they undertake 'bulk' surgery such as hip replacements, cataract operations or MRI scans rather than more complex operations such as neurosurgery.
