Claim:
1. A method of maintaining the structure of an opening in the anterior capsule formed by a capsulorhexis comprising: (a) creating an opening in the anterior of a capsular bag by capsulorhexis; (b) inserting an intraocular lens (IOL) through the opening completely into the capsular bag; and (c) separately inserting a device into the opening in the anterior capsule after the intraocular lens is completely inserted into the capsular bag, the device comprising an annular shaped main body including a peripheral portion and an opening therethrough, wherein the peripheral portion engages with the inside peripheral edge of the opening in the anterior capsule, and wherein an anterior aspect of the device protrudes anteriorly for 1-2 mm completely around the opening in the anterior capsule to extend between the anterior capsule and an iris, thereby minimizing any gap that may exist between the anterior capsule and the iris and blocking peripheral light towards a periphery of the intraocular lens, so that dysphotopsia is minimized.
