Abstract Details

Purpose:

To measure and compare the resistance force for intraocular lens (IOL) insertion using syringe-type injector systems.

Setting:

The David J Apple International Laboratory for Ocular Pathology, Department of Ophthalmology, University of Heidelberg, Heidelberg, Germany

Methods:

Using three different preloaded implantation systems (RayOne, CT Lucia 601P - Accuject and AcrySof IQ - Ultrasert), intraocular lenses were inserted into the lens capsular bag of porcine eyes after phacoemulsification. For each system, the resistance force for the IOL insertion into the porcine capsules was measured using an automated force gauge system. As a control, the resistance force of the IOL delivery onto a plastic dish with beer was measured. Changes in the resistance force as well as its curves and maximum values were evaluated. The mean total area under the curve (AUC) was compared.

Results:

Each implantation system demonstrated a characteristic maximum resistance force behavior unique to its own design. Maximum resistance forces in the pig eye and control group in Newton [N], as well as the total area under the curve forces in [N] in the pig-eye and control groups were different between the groups.

Conclusions:

In this ongoing study pressure profiles of IOL implantation show clear differences between the IOL implantation systems.
