Chalazion still red swollen 5 months after procedure. (photos)

It is likely there is residual stye/chalazion present that needs to be drained. See an oculoplastic specialist for evaluation.

I have had very good success treating these with a steroid injection of kenalog.  This avoids unnecessary surgery on a very delicate area. The steroid will be helpful even though you had a procedure on the chalazia and it has been going on for 5 months.  I use a numbing cream and then use a little bit of local so the whole thing is surprisingly comfortable.

There may be residual encapsulated chalazion/ stye in the eyelid.  An incision and drainage does not guarantee total removal, and the swelling and redness can persist for months after.  See an oculoplastic specialist for an in-person examination and to learn more.  

Hello mitt1997,
This will resolve. Not to worry. I suggest you see an ophthalmologist or an oculoplastic surgeon in your area. Options could be steroid injections, eye drops or ointment or surgical removal.
Cheers
