Abstract Details

Purpose:

To assess the injectability of various hydrophobic intraocular lenses in standardized conditions of injection

Setting:

Acrylian Ltd, 22 rue de la Ganzau 67000 STRASBOURG, FRANCE; Clinique Juge, 108 rue Mermoz 13008 MARSEILLE FRANCE

Methods:

Medicel Accuject injectors with cartridges of 2.1mm, 1,8mm and 1,6mm and Medicel ViscoJect injector with cartridges of 1.5mm were used at an external temperature of 19°C; the lenses were folded under protection of 1,2% hyaluronate OVD and then injected in a Petri box filled with water at 34°C, using a mechanical device with measurement of the strength necessary to push the IOL; video of unfolding IOLs were also performed

Results:

2 or 3 samples of the different models of IOLS were used. SN60WF, FocusForce, Tecnis and Vivinex IOLs were injectables only through 2.1mm cartridges; Aris, Acrygem2, Envista, EyeCeeOne and Lucia IOLs could be injected with the 1.8mm, 1.6mm and 1.5 mm cartridges. Video analysis of unfolding durations showed: less than 5 seconds for FocusForce IOL; 5-10 sec for Artis, AcryGem2, EyeCeeOne, Vivinex and SN60WF IOLs; more than 15 sec for Envista, Tecnis and Lucia IOLs

Conclusions:

We found significant differences in minimal sizes of injection, and significant differences of unfolding duration of the studied IOLs
