Scleral tattooing Paul Mowery (aka "Pauly Unstoppable"/"Farrah Flawless"). Larratt got the idea after Dutch eye surgeon Gerrit R. J. Melles gave Shannon's then-wife Rachel Larratt an eye implant. She had a small piece of thin platinum jewelry inserted over the sclera, which is the white layer of the eye, and under the conjunctiva, which is a clear layer covering the sclera. The method Melles had developed included injecting a small drop of saline in order to create a fluid filled pocket before inserting the implant into this pocket, which would gradually shrink and leave only the jewelry behind. Shannon then imagined the
Eodiscina surface. The interlensar sclera is not deeper than the lenses. This type of eye is called abatochroal. A second type of eye, called schizochroal, is unique to the Phacopina suborder, and has up to several hundreds of relatively large lenses (0.05-0.5 mm), that do not touch either, but the corneal membrane extends into the sclera outside the lens, and the sclera is deeper than the lens. The most usual type of trilobite eye, called holochroal, has usually thousands of small hexagonal lenses without an interlensar sclera, and a common cornea. Many later Eodiscina however, lost their visual organs altogether, and
