Abstract Background To evaluate application of AS-OCT in PCO severity assessment and analyse relationship between PCO severity and IOL characters. Methods PCO patients were prospectively recruited. Cross-sectional images of the anterior segment at horizontal and vertical medians were acquired with AS-OCT. The area of the IOL-PC (posterior capsular) space and PCO severity (area, thickness and density at 3 mm and 5 mm IOL optic regions) were measured. The relationship between visual acuity and PCO severity, comparisons of PCO severity and IOL-PC space using varied IOL designs were analysed. Results One hundred PCO eyes were enrolled. IOL-PC space and PCO thickness and area was positively correlated with axial length. The cut-off level of visual acuity: was 0.52 Log MAR. Visual acuity were positively correlated with PCO area and thickness when visual acuity was ≤ 0.52 Log MAR. 3-piece C haptic IOL showed a smaller PCO area and thickness than the 1-piece 3 haptic IOL and 1-piece 4 haptic IOL. PCO area and thickness values for an IOL with a diameter ≤ 11.0 mm were greater than for an IOL with a diameter of 12.5 mm. The differences were statistically significant. PCO area and thickness increased when IOL haptic angulation increased (from 0 to 12 degrees). Conclusions In PCO eyes, cut-off level of visual acuity was 0.52 Log MAR. With more severe PCO, visual acuity maybe not enough to describe the visual function impairment. PCO severity and IOL-PC space was significantly correlated with axial length and IOL design and material.
