Predictors of successful laser capsulotomy for significant posterior capsule opacification after phacoemulsification

Purpose: this study aimed to determine the reasons behind the failure of laser capsulotomy (lc) performed for significant posterior capsular opacification (pco). methods: eighty-eight eyes of 88 patients referred for lc at a tertiary care center were retrospectively analyzed. the data recorded included the cause of cataract,visual acuity,duration of pco,location of pco,intraocular lens (iol) position,iol type,and lens capsule status. these data were later analyzed for determining the requirement of high pulse energy during lc and the success rate of primary lc. results: the mean age of the participants was 55.77 ± 18.60 years with 58 (65.9%) male patients. the mean duration between cataract and lc surgeries was 45.58 ± 37.33 months. senile (n=58),uveitic (n=12),post-pars plana vitrectomy (ppv) (n=12),and traumatic (n=6) cataracts were the common causes. late-presenting pco,trauma,uveitis,sulcus placement of iols,irregular capsulorhexis shape,and polymethyl methacrylate (pmma) iols were significantly associated with unsuccessful lc and/or higher pulse energy settings during lc. conclusion: significant pco is often associated with cataract caused by uveitis or trauma,and after ppv. pco associated with trauma,sulcus placement of iols,and pmma iols may need multiple lcs. takkar brijesh 1 dr. rajendra prasad centre for ophthalmic sciences,aiims,new delhi chandra parijat 2 dr. rajendra prasad centre for ophthalmic sciences,aiims,new delhi temkar shreyas 3 dr. rajendra prasad centre for ophthalmic sciences,aiims,new delhi singh ashutosh 4 dr. rajendra prasad centre for ophthalmic sciences,aiims,new delhi bhatia indrish 5 dr. rajendra prasad centre for ophthalmic sciences,aiims,new delhi pandey sk,apple dj,werner l,maloof aj,milverton ej. posterior capsule opacification: a review of the aetiopathogenesis,experimental and clinical studies and factors for prevention. indian j ophthalmol 2004;52:99-112. mcdonnell pj,zarbin ma,green wr. posterior capsule opacification in pseudophakic eyes. ophthalmology 1983;90:1548-1553. rabsilber tm,reuland aj,entz bb,holzer mp,limberger ij,auffarth gu. quantitative evaluation of acrylic and silicone intraocular lenses with a sharp optic edge design. © 2017 journal of ophthalmic and vision research published by wolters kluwer - medknow.
