We assessed anterior capsular overlap, intraocular lens-capsule adhesion, and capsular bending. In addition to\u00a0measuring the intraocular lens-posterior capsule distance and capsule bending angle\u00a0(CBA), the PCO parameters (area, density, and score at 6-, 5-, and 3-mm intraocular lens optic regions) were recorded. The associations between capsular bend and PCO type and characteristics were investigated. A control group of 12 eyes without PCO was used to compare the study variables.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>With p values greater than 0.001, there was a statistically significant difference in the mean PCO area and score at the 6-, 5-, and 3-mm optic zones in different PCO types, with the pearl type having the highest value, followed by the mixed type, and finally the fibrosis type. The PCO group had a significantly higher mean\u00a0CBA than the control group (<jats:italic>P<\/jats:italic>\u2009=\u20090.001). CBA was positively related to intraocular lens-posterior capsule distance, PCO area, and PCO score at the 6-, 5-, and 3-mm zones (<jats:italic>P<\/jats:italic>\u2009=\u20090.001). The receiver operating characteristic curve's cut-off point for CBA was 96.85\u00b0 when comparing PCO cases to controls.
