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
Aberrations of the eye converge to a perfect point, the wavefront emerging from the optical system must be a perfect sphere centered on the image point. The distance in micrometers between the actual wavefront and the ideal wavefront is the wavefront aberration, which is the standard method of showing the aberrations of the eye. Therefore, aberrations of the eye are the difference between two surfaces: the ideal and the actual wavefront. In normal population the dominant aberrations are the ordinary second-order spherocylindrical focus errors, which are called refractive errors. Higher order aberrations are a relatively small component, comprising about 10% of the eye's total
