a gradual loss of vision with abnormal color perception and glare.
A patient with bilateral cataracts is scheduled for an extracapsular cataract extraction with an interocular lens implantation of one eye. Preoperatively, the nurse should?
assess the visual acuity in the inoperative eye to plan the need for postoperative assistance.
Retinal tears leading to retinal detachment are most often caused by?
Vitreous shrinking during aging that pulls and tears retina.
