Can I get double eyelid surgery with ptosis?

Doctor says I have ptosis (weak eye opening muscle).

Consulted at multiple places - Clinic A says ptosis correction first, Clinic B says can fix with double eyelid surgery.

**My Confusion**
- Is ptosis correction separate?
- Can double eyelid fix it?
- Which is safer?
- Cost difference?

**What I've Learned**
- Mild ptosis: Double eyelid can help
- Severe ptosis: Needs dedicated surgery
- Get specialist opinion

Ptosis patients, please advise!
