A fresh look at iontophoresis

Arch Ophthalmol. 1984 Dec;102(12):1825-9. doi: 10.1001/archopht.1984.01040031483028.


The rate of penetration of fluorescein and gentamicin ions into the anterior chamber of the rabbit was increased more than 100-fold by the passage of 1 mamp; the amount of drug that penetrates is better controlled by iontophoresis than by instillation. The potential value, the safety and the limitations of this procedure are discussed, and a theoretical basis for the increase is provided. Practical methods of using iontophoresis in the clinic are described. A 30-s application should result in a therapeutic level of the antibiotic in the anterior segment over a 12-hour period in eyes with an intact epithelium.
