Aphakia is the absence of the lens of the eye, due to surgical removal, such as in cataract surgery, a perforating wound or ulcer, or congenital anomaly. It causes a loss of ability to maintain focus ( accommodation ), high degree of farsightedness ( hyperopia ), [ 1 ] and a deep anterior chamber .

It was a joyful unforgettable moment the Sinclair family has been waiting for, when their 10-month-old baby Charlie heard for the very first time in her life.
Aniseikonia due to uniocular aphakia is best corrected surgically by intraocular lens implantation. [4] Similarly retinal aniseikonia is corrected by treating causative retinal disease. [4] Note however that before the optics can be designed, first the aniseikonia should be measured.
Oculomotor nerve palsy or oculomotor neuropathy [1] is an eye condition resulting from damage to the third cranial nerve or a branch thereof. As the name suggests, the oculomotor nerve supplies the majority of the muscles controlling eye movements (four of the six extraocular muscles, excluding only the lateral rectus and superior oblique).
