Cataract extraction and intraocular lens implant is a generally safe procedure,so when pain occurs after the procedure,it indicates that infection has set in or there is bleeding in the procedure site and it is advices that when a patient notices any of these,it should be reported immediately. Certain things should be avoided after cataract extraction and intraocular lens implant, things like soap,having a bath,washing the hair can all irritate the eye so all these should be avoided from few days to atleast 2weeks after the surgery.
When the patient that has undergone cataract extraction and intraocular lens implant experiences flashes of light,it indicates they there is retinal detachment,this is not expected, but if it is experienced by the patient,it should be reported immediately too.
