Image Quality

• Extremely important

• Individual tolerances

• Individual appreciation

So, what is the PROBLEM?

Multifocality

Crystalens® AOIntroduction• 5th generation Crystalens

– Lineage: AT-45, AT-45SE, Five-O, HD

• Aberration free optic design• Aspheric: anterior & posterior surfaces• No Spherical aberration• Less sensitive to decentration• Designed for improved quality of vision• FDA Approved 10-23-2009

Diffractive IOL Diffractive IOL

WARNINGS:1. Some visual effects may be expected due to the superposition of

focused and unfocused multiple images. These may include some perceptions of halos or radial lines around point sources of light under

night-time conditions.

2. A reduction in contrast sensitivity as compared to a monofocal IOL may be experienced by some patients and may be more prevalent in low lighting conditions. Therefore, multifocal patients should exercise caution

when driving at night or in poor visibility conditions.

Results• Monofocal IOL’s have superior optical

performance ~ contrast sensitivity, MTF

• Multifocality with “ splitting of light “ results in a trade off of greater range of vision but negative consequences to vision quality

If you had a presbyopic IOL implanted in your own eye what would you be more willing to live with if you had to?

Question #1

a. Readers for near

b. Night symptoms

c. Slightly blurred image at all focal points
