2PURPOSE
To compare the visual quality of the aspheric
diffractive multifocal intraocular lens (IOL)
with of the aspheric monofocal IOL.
3PATIENTS IOLS
- Bilateral cataract surgery
- IOL power was aimed for emmetropia
4METHODS
Distance visual acuity (VA)
Uncorrected Corrected Near VA
Uncorrected Distance-corrected
Corrected Contrast sensitivity (CSV-1000 chart)
Above measurements were performed more than 1
month post-operatively.

8DISCUSSION
- The modified prolate anterior surface of Tecnis
multifocal IOL significantly reduces spherical
aberration. - This structure may provide improving contrast
sensitivity and image quality.
9CONCLUSION
Tecnis ZM900 multifocal IOL provided good
uncorrected distance and uncorrected near visual
acuities, with minimizing loss of contrast
sensitivity.
