Posterior capsule opacification in myopic eyes

Abstract

When an acrylic IOL of low-power, zero-power, or minus-power with a sharp optic edge was implanted, high myopia and long axial length were not associated with the degree of PCO.

Prospective evaluation of posterior capsule opacification in myopic eyes 4 years after implantation of a single-piece acrylic IOL

“…In eyes with a 3-piece acrylic IOL with a sharp optic edge, Hayashi et al 20 found high myopia and long AL were not associated with the degree of PCO. We did not attempt to determine whether the degree of PCO varied among eyes with high, moderate, and mild axial elongation.…”

“…[39][40][41][42][43][44] Posterior capsule opacification in patients with myopia has been observed mainly by judging the incidence of Nd:YAG capsulotomy, which is a subjective method for comparing groups. Recently, Hayashi et al 20 described an objective method for determining PCO density using a Scheimpflug videophotography system. We decided to evaluate PCO by using digitally acquired retroillumination photographs because they provide excellent image quality and high reproducibility.…”

“…17 Furthermore, most studies of the outcomes of cataract surgery in myopia were of young patients having refractive lens exchange 18 or poly(methyl methacrylate) (PMMA) IOL implantation 14,15,[17][18][19] or of eyes with various levels of myopia without a comparative group. 20 It is therefore difficult to clearly correlate the development of PCO with the factors of age, refractive lens exchange, or solely myopia.…”

Three-haptic intraocular lens for myopia: Early results

“…Most previous studies report PCO rates of 20% to 50%, 2,20-25 although the rate varies from 3.5% (at 24 months) 6 to 61.0% (mean follow-up 64 months) 7 according to the surgical technique, length of follow-up, and inclusion criteria. It will be of interest to see whether Nd:YAG capsulotomy is associated with an increased RD rate in our patients; 1 study 26 in which 85% of patients were left aphakic after lens extraction found that Nd:YAG laser capsulotomy increased the rate of subsequent RD.…”

“…5 The reported rate of posterior capsule opacification (PCO) after cataract surgery in myopic patients varies greatly. Some studies found no increased risk in cases of myopia 6 and attribute the low PCO rates to the use of sharp-edged acrylic IOLs. Other studies report rates as high as 61%.…”
