Abstract
The method of controlling a lens haptic during insertion of an artificial lens into the eye, that includes releasably supporting an end portion of the haptic in a supported position relative to the lens during lens insertion into the eye, such supporting being independent of the lens itself; and permitting the supported end portion of the haptic to progressively release from support as the lens becomes positioned in the eye.

The method of controlling a lens haptic during insertion of an artificial lens into the eye, that includes
- a) releasably supporting an end portion of the haptic in a supported position relative to the lens during lens insertion into the eye, such supporting being independent of the lens itself,
- b) and permitting the supported end portion of the haptic to progressively release from support as the lens becomes positioned in the eye,
- c) and including tensioning the haptic in said supported position, whereby the tensioned haptic aids release of the lens from support.
The method of controlling a lens haptic during insertion of an artificial lens into the eye, that includes
- a) releasably supporting an end portion of the haptic in a supported position relative to the lens during lens insertion into the eye, such supporting being independent of the lens itself,
- b) and permitting the supported end portion of the haptic to progressively release from support as the lens becomes positioned in the eye,
- c) and wherein the lens is folded during said insertion into the eye, and said permitting includes allowing unfolding of the lens in the eye in such manner as to assist in said release.
The method of controlling a lens haptic during insertion of an artificial lens into the eye, that includes
- a) releasably supporting an end portion of the haptic in a supported position relative to the lens during lens insertion into the eye, such supporting being independent of the lens itself,
- b) permitting the supported end portion of the haptic to progressively release from support as the lens becomes positioned in the eye,
- c) providing insertion instrumentation to engage and transport the lens into the eye, and wherein said releasable supporting of the haptic end portion includes locating the haptic end portion in a recess provided by said instrumentation,
- d) providing said recess in said instrumentation,
- e) said recess being provided in the form of a receptacle, and a guide channel is provided leading toward the receptacle, to guide haptic end reception into the receptacle,
- f) and wherein said instrumentation includes a forceps first arm which is elongated, and said recess is provided in said arm.
