Application of Spectral Domain Optical Coherence Tomography to Objectively Evaluate Posterior Capsular Opacity In Vivo

Figure 1

Illustration graph of the PCO evaluation method with the Pentacam (the figure was acquired at the horizontal meridian). Measurement of PCO characteristics in one cross-sectional image. S: surface; S1: anterior surface of IOL; S2: posterior surface of IOL; S3: posterior capsule. Point A is the centre of the horizontal line, which is the centre of the pupil, and the distance between points B and C is 5 mm of the central optic region. The PCO area is located between S2 and S3, which is indicated with a red line.
