Methods

• A reading chart based on the MNRead chart was
  developed in Spanish.
• 25 patients implanted binocularly with Synchrony
  IOL
• 15 patients implanted with conventional monofocal
  IOLs (AcrySoft) served as controls

3
Methods

• Measured through the best-corrected DISTANCE
  visual acuity (BCDVA) at 40 cm.
• No near Add power was used
• Measurements
• Reading Acuity (logRAD)
• Maximum Reading Speed (words/min)
• Reading speed at newspaper print size (logRAD 0.4)

Reading Speed at 0.4 logRAD
Mean reading speed at 0.4 logRAD (newspaper print
size) was also significantly better in eyes with
Synchrony IOLs (160.6 words/minute) vs control
(23 words per minute). At this print size, 88
of Synchrony eyes could read at least 80
words/min vs 13 of controls.

Summary

• The maximum reading speed and reading acuity was
  better in eyes implanted with Synchrony IOLs
• Synchrony also showed excellent reading speed and
  reading acuity at newsprint size, with 88 of
  eyes reading at least 80 words/min

9
Summary

• This study demonstrates that Synchrony can
  provide adequate near functional vision, without
  compromising intermediate vision, or inducing
  haloes
• A new test for functional intermediate vision is
  under development, and will be shown at upcoming
  meetings
