Evaluation of PCO severity using RTVue-100 OCT. a Comparison of opacification area between pear type and fibrosis PCO (Mann-Whitney U test, Z = − 1.96, p = 0.05 at 3 mm optic zone; **Z = − 3.14, p = 0.002 at 5 mm optic zone; **Z = − 2.71, p = 0.007 at 6 mm optic zone). b Comparison of PCO thickness between pear type and fibrosis PCO, the difference was statistically significant (Mann-Whitney U test, Z = − 3.05, p = 0.002 at 3 mm optic zone; Z = − 2.52, p = 0.01 at 5 mm optic zone; Z = − 3.15, p = 0.002 at 6 mm optic zone). c Comparison of PCO density between pear type and fibrosis PCO (Mann-Whitney U test, Z = − 0.65, p = 0.51 at 3 mm optic zone; Z = − 0.15, p = 0.88 at 5 mm optic zone; Z = − 1.00, p = 0.32 at 6 mm optic zone). d Correlation of OSI changes and PCO area at 3 mm IOL optic region before laser capsulotomy for all eyes (r = 0.43, p = 0.02)
