Purpose:
To analyze the effect of optical parameters on the outcomes of accommodating intraocular lens (IOL) implantation in cataract surgery.
Setting:
Department of Ophthalmology, KULeuven University, Leuven, Belgium.
Methods:
Thin-lens approximation optics were used to obtain a formula containing the following variables: axial length (AL), mean keratometry (Km), anterior chamber depth (ACD), and presumed anterior shift of the IOL (dACD). The influence of these variables was separately analyzed.
Results:
The accommodative amplitude (AA) decreased with a longer AL and higher Km. The AA varied between -5.4 diopters (D) and 0.0 D in eyes with an AL between 20.0 mm and 28.0 mm and a Km between 38.0 D and 52.00 D. The dACD was also a significant factor influencing the AA. The ACD had less influence on the AA.
Conclusion:
The obtained formula could guide selection of candidates for accommodating IOL implantation.
