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 ...

If the natural lens is left in the eye, the IOL is known as phakic, otherwise it is a pseudophakic lens (or false

A well-constructed scleral tunnel is held closed by internal pressure, is watertight, and does not require suturing.
