Summary: Posterior capsule opacification evaluation is a difficult task. Subjective clinical methods based on visual acuity testing, contrast sensitivity and glare presence are not errorless. Capsulotomy is not a proper index of PCO degree. The most reliable are methods based on photography in advanced computer systems. EPCO system determines the degree of opacification density by densitometry, POCO - surface of PCO in percentage, AQUA compares degree of opacification grey with matrix. POCOman is a semi objective evaluation method by the program available in internet. A modern method for evaluation of the posterior capsule opacification is SOCT. None of the systems ensures fully univocal and repeatable determination of PCO degree, therefore, further studies on the method allowing evaluation of posterior capsule opacification are necessary.
Keywords: posterior capsule opacification, methods of opacifications examination, computer systems for PCO evaluation.
