From: Anti-amoebic and biocompatible properties of nephrite-embedded contact lenses
Light microscopic images (original magnification×100) of Acanthamoeba attached to different types of contact lenses (CLs). Acanthamoeba attached to (A) Clear CLs, (B) Cosmetic CLs, and (C) Nephrite-embedded CLs, respectively. Acanthamoeba attached to nephrite-embedded contact lenses are indicated with arrows to distinguish them from nephrite particles. (D) Graph showing the number of Acanthamoeba attached to three types of CLs. Nephrite-embedded CLs had significantly lower number of Acanthamoeba (n = 52.3 ± 2.6) attached compared with clear CLs (n = 94.0 ± 8.6, p = 0.0093), and cosmetic CLs (n = 28.0 ± 1.6, p = 0.0068). Statistical analysis was done using unpaired Welch’s t-test.
