IOL Scaffold foreign bodies can enter the eye and can get lodged on the retina or vitreous. This is often removed through the open method of opening through the sclera (white coat of the eye). While removing large intraocular foreign bodies (IOFB), it may drop or slip onto the back part of eye again. In order to prevent this, the IOL can be placed on the sulcus or glued to the sclera and the IOFB can be removed over it (Fig 4). This will prevent the accidental slippage of IOFB into the eye. There has been no increased risk of postoperative complications
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
