Visual Acuity outcome in the two treatment groups during the 1 year follow up after surgery

Postop time	Treatment group		Achieved 6/9 or better vision—ie, <0.2 logMAR	Proportion ratio: Phako/ECCE (95% confidence limits)	Fisher's exact test p value
Postop time	Treatment group		No (%)	Proportion ratio: Phako/ECCE (95% confidence limits)	Fisher's exact test p value
