Cellular experiments evaluating lens epithelial cell morphology, adhesion, and migration were conducted to exclude cytotoxic effects. Twelve New Zealand rabbits underwent implantation of a brown diaphragm IOL in one eye, whilst an additional 12 had a commercially available foldable IOL implanted, followed by slit\u2010lamp evaluations of inflammatory reactions and capsular opacification. Corneal endothelial cells density was measured before and after implantation. Aqueous humour samples were obtained weekly for liquid chromatography\u2013tandem mass spectrometry (LC\u2013MS\/MS) analysis to investigate dye leakage from the brown\u2010diaphragm IOL. Following 12\u2009weeks of observation, haematoxylin and eosin staining of ocular tissue and scanning electron microscopy (SEM) of the IOL surface were performed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Results from in vivo experiments found no statistically significant differences between the two groups in terms of postoperative inflammation and capsular biocompatibility. No significant changes in corneal endothelial cell density were observed in either group before and after surgery.

Histopathology of ocular sections and SEM imaging of IOL surfaces showed similar changes in both groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The newly invented IOL showed good biocompatibility and biosafety.
