Scleral tattooing

The process remains uncommon due to professionals' discomfort performing the procedure[1] and is illegal in the American states Oklahoma and Indiana and the Canadian provinces Ontario and Saskatchewan.

[7][8][9] As of March 2013, both Rahn and Larratt have died of causes unrelated to the procedure (murder and tubular aggregate myopathy, respectively), making Farrah Flawless the person who has had scleral tattoos for the longest period of time in the world.

The technique he used during the procedure, injecting the sclera with blue dye, is similar to an established method practiced by surgeons who install eye implants.

[11] Larratt's wife Rachel underwent a procedure where the surgeon injected small drops of saline to create a fluid-filled pocket between the conjunctiva and the sclera, where he inserted a thin piece of platinum jewelry.

[12] Larratt called Cobra's procedure "effectively painless because there aren't nerve endings in the surface of the eye" and claimed that the after-effects included minor pain, bruising, discomfort, and mild blistering between the sclera and conjunctiva.
