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 seconds— at temperatures above will begin to cause scarring, and above will cause extreme changes in the sclera and surrounding tissue. Such long exposures even in industrial settings are virtually nonexistent. The sclera is highly resistant to injury from brief exposure to toxic chemicals. The reflexive production of tears at the onset of chemical exposure tends to quickly wash away such irritants, preventing further harm. Acids with a pH below 2.5 are the source of greatest acidic burn risk, with sulfuric acid, the kind present in car batteries and therefore commonly available, being among the most dangerous in this regard.
