Study Design
Patients (eyes)

• prospective, randomized implantation of 46S and
  46LC in left or right eye
• two surgeons
• coaxial mini phaco2.3 mm temporal stab. incision
• intra-individual comparison
• 2 mo's post-op clin. outcome, BCVA, wavefront
  analysis (WaveScan), contrast sens. (contrast
  sensitivity tester Model 1800)
• patient questionnaire
