Eyelid chalazion (stye) removal
The only effective treatment to get rid of the chalazion would be to surgically cut it out using hidden inside eyelid incision under local anesthesia. See following link.
Warm compresses will be completely ineffective after a year.
The eyedrops are just going to irritate the eyes and will have absolutely no effect on the bump. This is not an infection and suggests that whoever is treating you does not know anything about eyelids. You would benefit from a real examination. Depending on precisely your history and findings, treatment can go one of two ways. An excisional biopsy might be advised to diagnose the bump or a corticosteroid injection may be recommended, which may be sufficient to melt the chalazia without the necessity of surgery.
It is a chalazia. I usually treat them with warm compresses and an antibiotic/steroid ointment for 2 weeks. If it doesn't go away, then I surgical drain them in the office. I would recommend you see an ophthalmologist/oculoplastic surgeon for evaluation and treatment.
Getting rid of a chalazion
Start wuth hot compresses (twice a day for 5 minutes) and washing the eyelids with mild soap. If it isn't improved in a week or two, see your ophthalmologist. You may need a steroid ointment at some point.
