Patent ID: 7182780

Claim:
A method of performing visual correction in a patient by replacing the natural lens with a lens implant, comprising: (a) excising an area of the anterior capsular bag of the eye having a sufficient size to surgically remove the natural lens; (b) locating a sealing device comprising a flexible plug part and removable adjusting means of a size sufficient to cover said excised area with said adjusting means to a position where a peripheral anterior surface of said plug part contacts the inner wall of the capsular bag so as to sufficiently cover said excised area, without additional sealing means, wherein the adjusting means protrudes outside the eye and is operated from outside of the eye to locate the sealing device; (c) delivering a lens filling material into the capsular bag by using a delivering means to temporarily displace and/or deform said plug part to admit passage into the capsular bag of said material; (d) before removing the delivery means, introducing lens forming material into the capsular bag to an extent that said material exerts a sufficient pressure on the posterior side of the plug part to seal the excised area without additional sealing means, so said lens material is prevented from being displaced from the capsular bag to the posterior chamber of the eye; and (e) finalizing the lens forming process in the eye, wherein the adjusting means of the sealing device is removed from the eye after completing the introduction of lens forming material into the capsular bag.
