Comparison of OVs values between pear type and fibrosis PCO. a 100% OVs, 20% OVs, 9% OVs comparison between pre-YAG and post-YAG, OVs at the three contrast were significantly improved after laser capsulotomy (Mann-Whitney U test, ^**Z = − 4.31, p ≤ 0.001; ^**Z = − 3.9, p ≤ 0.001; ^**Z = − 3.96, p ≤ 0.001), b 100% OVs, 20% OVs, 9% OVs comparison between pear type PCO and fibrosis PCO before laser capsulotomy, OVs in fibrosis PCO was significantly higher than pear type PCO (Mann-Whitney U test, **Z = − 4.4, p ≤ 0.001; ^**Z = − 4.34, p ≤ 0.001; ^**Z = − 3.12, p = 0.002), c 100% OVs, 20% OVs, 9% OVs comparison between pear type PCO and fibrosis PCO after laser capsulotomy, there was no significant difference here
