Transcorneal

Transcorneal refers to a path or route that passes through the cornea of the eye. The cornea is the transparent outer layer at the front of the eye that covers the iris, pupil, and anterior chamber. It plays a significant role in refracting light.

In medical contexts, "transcorneal" is often used to describe procedures or the passage of substances. For instance, transcorneal electrical stimulation involves applying electrical currents across the cornea, which can be used in the treatment of certain eye conditions. This method is considered non-invasive as it bypasses the need for surgical penetration of deeper eye structures.

Similarly, the delivery of certain medications or therapeutic agents can be described as transcorneal. This implies that the substance is intended to cross the corneal barrier to reach tissues within the anterior part of the eye, such as the iris or ciliary body. The permeability of the cornea to different substances is a key factor in transcorneal drug delivery efficacy. Research continues to explore new methods to improve the efficiency of transcorneal drug penetration for better treatment outcomes.
