Hypothesis
The study aims to compare the effects of BAC-preserved and unpreserved antiallergic eye drops on a 3D corneal epithelial model.
Conclusion
BAC-preserved solutions decreased cell viability and induced apoptosis, while unpreserved solutions did not impair cell structures, suggesting better tolerance for the ocular surface.
Supporting Evidence
- BAC-preserved solutions significantly decreased cell viability compared to control.
- Unpreserved formulations showed similar viability to the control.
- BAC-induced apoptosis was concentration-dependent.
- CD54 expression increased with BAC-preserved solutions.
- Occludin distribution was disrupted by BAC-containing solutions.
Takeaway
Some eye drops with preservatives can hurt your eyes, while those without preservatives are safer and better for your eyes.
Methodology
3D-HCE model was treated with various eye drops, and cell viability, apoptosis, and protein expression were assessed using MTT and TUNEL tests.
Limitations
In vitro findings may not fully represent in vivo conditions.
