[EN] Purpose: A new technique for the assessment of the optical quality of multifocal
intraocular lenses (MIOLs) under monochromatic and polychromatic illumination
is presented.
Methods: The system provides, in a totally automated procedure, the modulation
transfer function (MTF) of the lens under test for different axial positions of the
object. The artificial eye admits different artificial corneas, to optimise the axial
resolution in the sampling of the MTF of the MIOL under test, and different
pupils, to test the dependence of the optical performance of the MIOL on the eye
pupil diameter.
Results: The performance and sensitivity of the apparatus is tested with different
commercial MIOLs. The through-focus MTF for a refractive MIOL was measured
at different moments during the process of hydration of a hydrophilic lens. Next,
to show the performance of our proposal, two commercial refractive and diffractive
MIOLs were evaluated.
Conclusions: We have designed a precise and robust optical method for testing
MIOLs in vitro. The proposed method represents a valuable technical improvement
to make the procedure of MIOL evaluation more versatile, efficient and
trustworthy.
