In brief: Indirectly, yes

Visual loss in and of itself will not cause a loss of cognitive function.
However, it may worsen the situation in people with dementia, as it impairs orientation and general functioning. So, a person with dementia and severe cataract may see an improvement in functioning if the vision is improved.
