Purpose:
|
The aim of this study was to investigate the effect of Tilt of IOLs in cataract surgery using Liu - Brennan optical eye model in a simulation.
|
|
Methods:
|
A phantom with the real eye parameters- Liu – Brennan model- and Tecnis Z9000 IOL were used for simulation
|
|
Results:
|
Results showed that with IOL tilts up to 8o in ±X direction the modulation transfer function (MTF) were constant. The results of IOL tilts in ±Y axes were the same as ±X direction. In the ±X and ±Y axes the 8? IOL tilt has no significant effect on the MTF and contrast of the eye.
|
|
Conclusion:
|
It can be said that the Tilt of Tecnis Z9000 IOL in vertical and horizontal axes have no significant effect on the visual quality of the patient and therefore no compensation methods required for improvement of the optical quality
