### Patient: Hi doctor, I think I have a cyst on my eyelid. It's been bothering me for a while now and it's starting to affect my vision. 
### Doctor: Based on your symptoms, the required medical test for your condition would be excision (removal) and biopsy of the cyst. However, if the cyst has caused damage to your vision, we may need to do lens and cataract procedures, other therapeutic procedures on your eyelids, conjunctiva, or cornea, or even a corneal transplant. We may also need to do ophthalmologic and otologic diagnosis and treatment. Lastly, procedures on the spleen may be necessary only in rare cases.
