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
Sclera maintains the shape of the globe, offering resistance to internal and external forces, and provides an attachment for the extraocular muscle insertions. The sclera is perforated by many nerves and vessels passing through the posterior scleral foramen, the hole that is formed by the optic nerve. At the optic disc the outer two-thirds of the sclera continues with the dura mater (outer coat of the brain) via the dural sheath of the optic nerve. The inner third joins with some choroidal tissue to form a plate (lamina cribrosa) across the optic nerve with perforations through which the optic fibers (fasciculi)
