Therefore, an accommodative intraocular lens (IOL) was implanted into freshly enucleated porcine eyes.

The eyes were glued into a mechanical apparatus to expand the ciliar body effectuating mechanical accommodation.

SETTINGDepartment of Physics and Medical Technology, VU University Medical Center, Amsterdam, The Netherlands.

METHODSA concept IOL that has a rotating focus mechanism and a mechanical frame that can operate within the range of ciliary muscle contraction of a typical 60-year-old human eye was designed.

To rotate the 2 lenses in the IOL with variable optical power, a frame that allows the displacement and force of the ciliary muscle to be transferred by the capsular bag was designed.

RESULTSRay tracing showed that the modulation transfer function (MTF) of the IOL in different accommodative states did not deviate to a great extent from the MTF of a monofocal IOL.
