Nd:YAG capsulotomy after phacoemulsification in vitrectomized eyes: Effects of pars plana vitrectomy on posterior capsule opacification

To compare the progression of posterior capsule opacification (pco) in patients who required nd:yag laser capsulotomy following either combined cataract surgery with pars plana vitrectomy (ppv; c-cv),sequential cataract surgery after ppv (s-cv),or cataract surgery alone (ca). the medical records of 321 patients (408 eyes) who underwent nd:yag capsulotomy were retrospectively evaluated. the ca group had a significantly longer time interval from cataract surgery to capsulotomy than that of both the cv group (p=0.006) and the s-cv (p=0.013) and c-cv (p=0.042) subgroups when age-matched comparisons were used. cv patients who implanted a hydrophobic acrylic iol had shorter time intervals than those of ca patients (p=0.028). cv patients had larger hazard of earlier capsulotomy than ca patients (hazard ratio (hr) = 1.337; 95% confidence interval (ci) 1.100-1.625; p=0.004). c-cv and s-cv patients both had larger hazard than ca patients in earlier capsulotomy (hr=1.304; 95% ci=1.007-1.688; p=0.044,hr=1.361; 95% ci=1.084-1.709; p=0.008,resp.). pco progresses more rapidly in patients undergoing combined or sequential cataract surgery and ppv than in patients undergoing ca. © 2014 jong hwa jun et al.
