title: Evaluation of the ZEBRA 2000 (Z-10) Breger Vision bifocal contact lens.
abstract: OBJECTIVE
  Evaluate the ZEBRA 2000 (Z-10) bifocal contact lens on presbyopic and aphakic patients.
  
  
  METHODS
  Thirty-eight patients, 37 presbyopes and one aphake, were fit in the Z-10 and evaluated for 6 months.
  
  
  RESULTS
  Twenty patients (53%) completed 6 months of contact lens wear. Ten (26%) discontinued due to lens related problems, three (8%) discontinued due to other health problems, and five (13%) were lost to follow-up. Average refits per eye were 1.75. Average distance visual acuity was 20/25; average near visual acuity was J1.6; average wear time, 11 hours. Patient satisfaction was rated good in comfort and vision and fair in nighttime glare by patients' subjective evaluation.
  
  
  CONCLUSIONS
  The ZEBRA 2000 (Z-10) can be a useful addition in fitting the general presbyopic patient population.
