Study Purpose
4
Study Population
iTrace aberrometry
Cycloplegia
3 mm zone
Matlab Software to calculate MTF
Monofocal IOL : 15 subjects (30 eyes)
Synchrony IOL : 16 subjects (32 eyes)

Objective Measurements3 mm pupil
Difference 0.01 um
8
Best-focus MTF 3 mm pupil
Differences are less than 10%

Mesopic Contrast Sensitivity
p=0.61 Wilcoxon Rank Sum Test

Dual Optic Design DOES NOT affect optical or retinal image quality of the eye
Objective evidence (iTrace, MTF)
Subjective evidence (CSF)
Contrast sensitivity of Synchrony is equivalent to that of monofocal IOLs
Discussion
11Discussion
Effect of the slight spherical aberration on Synchrony would only yield 0.42 D of increased depth of focus
Calculations based on Rocha’s work *
The improved near vision of Synchrony patients MOST LIKELY due to true accommodation

12Conclusion
Quality of Vision of Synchrony IOL similar to standard monofocal IOLs
Measured Subjectively
Measured Objectively
Improved Near Vision with Synchrony
Not related to increased depth of focus
