Primary Outcome Measures
NameTimeMethod
Posterior Capsule Opacification (PCO)2 years after surgery

Thickening and opacification of the transparent membrane on which the intraocular lens is placed assessed by taking a digital retroillumination image of each eye with a dedicated retroillumination camera system. The photographs were analyzed with POCO software to measure the percentage area of PCO in the capsulorhexis area.

100% LogMAR Best Corrected Visual Acuity (BCVA)24 months after surgery

Best spectacle corrected vision was recorded for each eye of the patients at above follow up visits. The Visual Acuity (VA) measurement was taken under high contrast (100%), which means that there was maximum contrast between the letters on the chart and the background.

VA is measured in logMAR. LogMAR is the "logarithm of the minimum angle of resolution". A lower logMAR value indicates better visual acuity.

9% LogMAR Best Corrected Visual Acuity (BCVA)24 months after surgery

Best spectacle corrected vision was recorded for each eye of the patients at above follow up visits. The Visual Acuity (VA) measurement was taken under low contrast (9%), which means that there was low contrast between the letters on the chart and the background.

VA is measured in logMAR. LogMAR is the "logarithm of the minimum angle of resolution". A lower logMAR value indicates better visual acuity.
