The aim of this study was to analyze the correlation between various factors related to cataract surgery and ciliary zonule weakness.
A retrospective analysis of medical record was conducted on 485 patients and 711 eyes who underwent cataract surgery at a single institution and all included patients were Asian.
Intraoperative ciliary zonule weakness was defined as small cortical particles observed in the anterior vitreous under a microscope at the end of cataract surgery. Pearson's correlation analysis was performed between intraoperative zonule weakness and risk factors, including age, systemic medical condition, axial length, corneal curvature, type and degree of cataract, size of continuous curvilinear capsulorhexis (CCC), duration of CCC time, frequency and completeness of hydrodissection, and presence of posterior capsule wrinkles during polishing. Subgroup analysis was performed on 74 eyes of 37 patients who underwent cataract surgery on both eyes within 1 month and had cortical particles in the anterior vitreous in only one eye.
During cataract surgery, anterior vitreous cortical particles occurred in 104 eyes (14.6%) out of 711 eyes. In the correlation analysis, posterior capsule wrinkles during polishing (r=0.659, p<0.05) and duration of CCC time (r=0.213, p<0.05) showed a significant correlation with the occurrence of anterior vitreous cortical particles. The subgroup analysis showed that posterior capsule wrinkles, completeness of hydrodissection, and duration of CCC time were significantly correlated with the occurrence of anterior vitreous cortical particles (r=0.606, 0.315, 0.269, p<0.05, respectively).
Zonule weakness during cataract surgery showed a significant correlation with posterior capsule wrinkles during polishing and duration of CCC time. However, there was no significant correlation found between preoperative factors and factors related to systemic conditions and ciliary zonule weakness during cataract surgery.
