Outcomes

Primary Outcomes

Best Corrected Visual Acuity

Best corrected vision was tested at 4 meters (m), 60 centimeters (cm), 40cm and at preferred distance (distance chosen by each subject) with a standard ETDRS chart for distance and a hand held chart for near. Scores were calculated using logMAR values. LogMAR is the "logarithm of the minimum angle of resolution". A lower logMAR value indicates better visual acuity. Preferred distance for each study group was as follows: ReSTOR +3 = 38.7 +/- 6.8 cm, Crystalens HD = 49.9 +/- 9.8 cm, Crystalens AO = 53.1 +/- 9.8 cm.

Time frame: 6 Months after surgery
