###Human: Will accidental entry of metal shavings into eyes lead to dry eyes and cataract? ###Assistant: Hi. Blurred vision may be due to a corneal problem, cataract or retinal scars. After trauma, all these complications can occur. Dry eyes will improve with artificial tears and cornea will get normal. But any corneal scar or opacity will remain and can hinder in vision. Cataract may be age-related or due to trauma. So if it is visually significant it is treated by surgical removal and intraocular lens implantation and your doctor will guide you when it needs to remove. The retinal scar can cause decrease vision significantly if they involve a central part of the retina called macula responsible for sharpest vision. But we can do much to treat retinal scars. So things to do are treat dry eyes and cataract (if surgery needed). I would suggest you visit your eye doctor and he will guide you accordingly.
