Performance of a truncated-edged silicone foldable intraocular lens in Indian eyes

Abstract

The CeeOn Edge 911A IOL was well tolerated in Indian eyes, and the posterior capsule remained clear. Larger patient groups with a longer follow-up will provide more useful information.

In vivo digital imaging of the square-edged barrier effect of a silicone intraocular lens

“…Intraocular lenses with at least 1 edge that creates a sharp bend in the posterior capsule have become the preferred design, regardless of the IOL material, because of the edge's barrier effect to LECs. [1][2][3][4][5][6][7][8]12,[14][15][16][17][18]23 This design modification can yield dramatic results. In a study of 45 eyes 2 years after surgery, Kruger et al 23 found a 0% PCO rate in eyes with a square-edged silicone IOL but of 43% in eyes with a round-edged silicone IOL made by the same manufacturer.…”

“…Nishi and coauthors 13 found that fibrotic fusion of the anterior and posterior capsule edges is essential to the PCO-minimizing effect of a sharp-edged optic. 13 Determining whether a specific IOL leads to a higher or lower PCO rate than another IOL has generally been accomplished through 1 of 3 methods: monitoring groups of patients in whom specific IOLs are implanted [14][15][16][17] ; tracking PCO or Nd:YAG capsulotomies visible in posterior photographs of eye-bank eyes 1,9,18 ; quantifying the late PCO visible in retroillumination photographs of patients' eyes. 12,14,[19][20][21][22] These methods rely on IOLs that have been in wide use 2 to 3 years before the incidence of PCO can be stated reliably.…”
