K-Y jelly for opthalmology: Here’s sex lube in your eye

kyA single substance can have multiple uses if you put your eye to it, as Dr. Hemant K. Mehta demonstrates:

A new use of K-Y jelly as a gonioscopy fluid,” Hemant K. Mehta, British Journal of Ophthalmology, vol. 68, no. 10 1984, pp. 765-767. (Thanks to investigator Dany Adams for bringing this to our attention.) The author, at Gwynedd District Hospital, Bangor, Wales, reports:

“Methylcellulose drops varying in strength between 0.3% and 2.0% and isotonic saline are the fluids currently used for gonioscopy and posterior segment examination of the eye with diagnostic contact lenses. The author reports the use of K-Y jelly for such examinations in over 80 patients after having it used on his own eyes without any immediate or delayed ill effects. No observable difference was found between saline drops, methylcellulose drops of 0.3% and 2.0%, and K-Y jelly as regards the visibility of the anterior and posterior segments of the eyes. The more viscous fluids of 2% methylcellulose and K-Y jelly were more convenient to use, as they rarely allowed interposition of air bubbles between the cornea and the contact lens. K-Y jelly was well tolerated by all subjects.”
