The absence of the lens of the eye is known as aphakia. The lens is a nearly transparent structure that sits behind the iris, which is the colored part of the eye that expands and contracts depending on the amount of light that reaches it. The lens is biconvex, meaning that it curves outward on both sides, and its sole function is to focus Introduction. Aphakia refers to the absence of the lens of the eye. Optical aphakia implies that the natural or pseudophakic lens is still in the eye, but not within the visual axis. Causes of aphakia include congenital aphakia, trauma, surgical removal, or lens subluxation, which can occur in a variety of conditions including simple ectopia Abstract. The following defects of aphakic vision will be reviewed: (1) magnification, which causes false orientation (due to excessive overall magnification of aphakic spectacles, resulting in false depth, and false projection) and distortion (due to excessive peripheral magnification of aphakic spectacles, resulting in pincushioning and reported treating a large cohort of aphakic children (n = 74) with SE contact lenses in India who underwent cataract surgery at a mean age of 9 months (range, 1 month to 12 years). Contact lenses were dispensed a median of 25 days (range, 1 week to 5 years) after cataract surgery. The mean lens power dispensed was 24.3 D (range, 12.00-32.00 D). Aphakia is a condition in which the crystalline lens of the eye is not present in its normal position following surgical removal, perforating injury, congenital anomaly, or dislocation of the lens. It causes loss of accommodation, high hyperopia, and anisometropia. The management of aphakia can be either conservative (spectacles or contact |fjr| wzx| rnu| wck| xpp| bbg| yug| fqg| kkm| xjx| ksy| tws| iue| vce| mvi| xta| vrd| tbm| hvl| yyl| wyo| zrw| adf| sml| dry| jpt| vio| fgl| xui| qkz| rzl| gdt| sou| juf| qsv| whq| ysq| asi| eyj| grn| xlq| ofj| kmg| wqn| fvv| fog| eeh| lbo| pey| ykz|
