This is a protocol rarely followed by Indian practitioners that when a patient gives history of any major short or long term illness, he/ she must consult the respected physician to proceed with the invasive procedures like Extraction, RCT, Implant, surgical grafting, cyst and tumor removal etc. If your father's cardiologist suggests for dental procedures to be carried out, risk of future complications will be reduced drastically.
todays cataract surgery is predominantly blood-less so there is hardly any chance of bleeding as surgery is usually performed using anaesthetic drops and without any injection.
only thing that you need to take care is have a proper physician checkup before you plan surgery
and have a anaesthetic standby
rest no other special advice
