Article Title: Frequency-Dependent Bioimpedance Signatures of Ocular Tissues in Intact Ex Vivo Eyes Under Simulated Surgical Conditions
doi: 10.64898/2026.05.14.725195
Figure Lengend Snippet: During measurements of the cornea and sclera, the ocular surface was continuously rehydrated with balanced salt solution (BSS) using a syringe (not pictured) to maintain physiological moisture conditions. The bottom-right inset shows a schematic of the data-acquisition workflow, including the probe–tissue interface, LCR meter, and PC.
Article Snippet: Preliminary data was collected from four eye samples across a frequency range of 5 kHz to 1MHz by the Keysight LCR meter. evaluates tissue-to-background contrast within relevant surgical media (BSS, OVD or gel, and composite intraocular fluid), demonstrating that tissue contact produces impedance values distinct from surrounding surgical media under simulated intraoperative conditions.
