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

Figure 5

Relationship between visual acuity and PCO scores at the 3 mm and 5 mm IOL optic regions. Spearman’s correlation analysis was used. (a) Visual acuity and PCO scores for all PCO (, ; , ); (b) visual acuity and PCO scores for pear-type PCOs (, ; , ); (c) visual acuity and PCO scores for fibrosis-type PCOs (, ; , ); (d) PCO scores with OCT and PCO scores with the Pentacam (, ; , ). PCO score = PCO area × (PCO density−light scatter intensity).
