This study aimed to determine the relationship between visual function impairment in 776 patients who had extracapsular cataract extraction with posterior chamber intraocular lens implantation and gender, age, preoperative visual acuity of both the operative and the contralateral eye, and presence of other ocular disease in the operative eye. It concludes that when deciding whether to perform cataract surgery, functional impairment must be considered in relation to the age and the gender of the patient, for the type of functional impairment varies in association with age and gender.
