Stomach-churning video shows a surgeon struggling to remove a ball of pus from an EYEBALL

For those with a strong stomach, a nauseating procedure shows a surgeon struggling to remove a ball of pus from an eyeball.
The unnamed patient, believed to be male and from Madrid, is thought to have been suffering from a 'fat pad', or pinguecula, in his eye.
In the gruesome footage, ophthalmologist Dr Arteaga Sánchez can be seen struggling to remove the pus from deep within the patient's eye.
After pulling vigorously, the thick, yellow debris came out in one satisfying bulge.
When held against the patient's eye, the pus was more than one quarter its size.
