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.

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 plana vitrectomy.
Visual outcome after cataract surgery was close to conformity with WHO guidelines in Buenos Aires, where more than 80% of post-surgery eyes had visual acuity of 6/18 (20/60) or better, but ranged between 60% and 79% in most of the other regions, and was less than 60% in Guatemala and Peru. [126]

At the beginning of the 20th century, the standard surgical procedure was intracapsular cataract extraction (ICCE). [7] In 1949, Harold Ridley introduced the concept of implantation of the intraocular lens (IOL), which made visual rehabilitation after cataract surgery a more efficient, effective, and comfortable process.
