To analyze the behavior of a new double-C-loop quadripod symmetrical intraocular lens (IOL) platform combined with a hydrophilic lens material and a new hydrophobic glistening-free acrylic lens material, Ankoris and Podeye, respectively, in silico (computer simulation), in vitro (laboratory investigation), and in vivo (rabbit model).

Experimental study.
An in silico simulation investigation was performed using finite elements software, an in vitro investigation according to the International Organization for Standardization (ISO11979-3:2012), and an in vivo implantation in a rabbit model with 4 weeks of follow-up. Postmortem data were collected by Miyake-Apple gross examination and histopathologic analyses. Biocompatibility and IOL centration were tested.
Both IOLs demonstrated statistically insignificant variations in posterior and anterior capsule opacification and Soemmerring ring formation. They were well biotolerated with no signs of toxicity, inflammation, or neovascularization. Axial and centration stability were noted in vitro and in vivo as a result of significant contact between surrounding tissues and haptics and the posterior portion of the optic.
The results suggest suitability of the double-C loop IOL platform for the manufacturing of premium (ie, multifocal, toric, and multifocal toric) IOLs.

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 16 November 2017.
All research outputs
#22,759,802
of 25,374,647 outputs
Outputs from Journal of Cataract & Refractive Surgery
#2,940
of 3,236 outputs
Outputs of similar age
#236,501
of 277,613 outputs
Outputs of similar age from Journal of Cataract & Refractive Surgery
#44
of 47 outputs
Altmetric has tracked 25,374,647 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,236 research outputs from this source. They receive a mean Attention Score of 4.7. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 277,613 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 47 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
