Primary Outcome Measures :
  1. Posterior Capsule Opacification (PCO) [ Time Frame: Up to 3 years ]
    Development of PCO using the EPCO Score. The EPCO score incorporates planimetric & grading assessments. The density of the opacification behind the Intraocular Lens (IOL) is graded clinically as follows: 0=No detectable opacification; 1=Minimal detectable opacification; 2=mild detectable opacification; 3=moderate detectable opacification; 4=severe detectable opacification. The individual PCO score is calculated by multiplying the opacification grade by the fraction of capsule area involved behind the IOL optic. The selection process and grading of areas are subjective.
