Hydrodelineation
Hydrodelineation
Hydrodelineation (pronounced: hy-dro-de-li-ne-a-tion) is a surgical technique used in ophthalmology to separate the nucleus of the eye lens into two or more parts. This technique is often used in cataract surgery to facilitate the removal of the lens nucleus.
Etymology
The term "hydrodelineation" is derived from three parts: "hydro" from the Greek word "hudōr" meaning water, "de" from the Latin word "de" meaning from or out of, and "lineation" from the Latin word "lineatio" meaning a marking with lines. Together, they describe the process of using fluid to delineate or mark out lines in the lens nucleus.
Procedure
During hydrodelineation, a balanced salt solution is injected into the substance of the lens nucleus. This creates a cleavage plane that separates the nucleus into two or more parts. The separated parts can then be more easily removed from the eye.
