Illustration of PCO evaluation using RTVue-100 OCT. a Assessment of PCO with cross-sectional image. L refers to line. L1, L2, L3, and L4 represent the anterior surface of IOL, the horizontal diameter of the IOL optic region, the posterior surface of IOL, and the posterior capsule, respectively. Distance from point A to C refers to the 3-mm IOL optic region, and point B is the center. Distances from point D to E, H to I, and F to G are the PCO thickness at the 3-mm IOL optic region and the central optic region. The IOL-posterior capsular space is the region between line 3 and line 4. The region around point DFHIGE is the PCO area at the 3-mm IOL optic region. b Pseudophakic eye with a clear posterior capsule
