Collamer Had Significantly Less HO Aberrations Than STAAR Plate And SA-60 (P 0.005).
Difference With Sensar Was Not Significant.

NoteNote
Sample size may be too small, especially with the Sensar group, and results could change with a larger sample. However, we have strong clinical indications that less higher order aberrations are induced with the Collamer lens as compared to plate lenses and AMO lenses.

SummarySummary
Three Other Foldable Lenses Tested Had Between 55% and 117% More Higher Order Aberrations at 1 Week Postoperatively than the STAAR Collamer IOL

Is it clinically significant? Is this especially significant in
patients with large pupils? Do we need a bigger implant? Do we need a different shaped
lens? Do we need a different edge? Do we need a different material?
