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
Evolution of the eye fast locomotion or navigation by vision. The rate of eye evolution is difficult to estimate, because the fossil record, particularly of the lower Cambrian, is poor. How fast a circular patch of photoreceptor cells evolve into a fully functional vertebrate eye has been estimated based on rates of mutation, relative advantage to the organism, and natural selection. However, the time needed for each state was consistently overestimated and the generation time was set to one year, which is common in small animals. Even with these pessimistic values, the vertebrate eye would still evolve from a patch of photoreceptor cells in
