What type of doctor is best to use to remove a chalazion? An eye doctor or a plastic surgeon? Or other?

Most ophthalmologists can perform chalazion excision. If needed, you can see an oculoplastic surgeon for the removal.

Usually an ophthlamologist can treat/remove an eyelid stye or chalazion but sometimes more expertise with an oculoplastic surgeon is required.

Thank you for your question.  The specialist that most often treats this area of the face is an oculoplastic surgeon.  He or she will possess the most intricate knowledge of the eyelid. 
Best of luck,

While I do remove these on occasion, I know my ophthalmology colleagues deal with them quite a bit. There is also a specialty called occuloplastic surgery which would likely be helpful to you. It really depends on your area.

Dear ritahamele,Seek out an expert oculoplastic surgeon or an ophthalmologist. They are most qualifies to diagnose and treat this condition. Although other physicians may also attempt this successfully, the oculo[plastic surgeon is trained in the anatomy of the eye.Cheers
