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.
