Understanding the spacing of placodes in the eye: A comparative study across age and species
The Anatomical Record, EarlyView.Abstract The conjunctival placodes of the avian eye form in an intriguing and conserved sequence in a circular annulus around the cornea. These 13–16 placodes develop into papillae that are essential for inducing underlying intramembranous flat bones, known as scleral ossicles, which form an important part of the ocular skeleton.

Journal of Contact lens Research and Science, 2018 Scleral lenses (ScCLs) are developed using the same material as rigid gas permeable corneal lenses yet the care of scleral lenses differs from corneal lenses. These large diameter rigid gas permeable lenses necessitate hygiene, care and compliance protocol that is more complex compared with corneal lenses.

Scleral suture-fixated intraocular lens explantation [PDF]
Eye, 2014 Sir, Scleral-sutured intraocular lens (IOL) implant is one of the common methods for correction of aphakia in eyes without adequate capsular support.1 Scleral-sutured IOLs can, however, be associated with a variety of complications that sometimes lead to the need for explantation of the implant.2 Although many reports describe insertion ...
