Illnesses that affect healing may make vision surgery a poor choice. If you have diabetes, HIV, lupus, or rheumatoid arthritis, talk with an ophthalmologist about your best options. Other conditions that need careful evaluation and could make you a poor candidate for surgery include:
- Dry eye
- Large pupils
- Thin corneas
Laser surgery is not a good idea for people with keratoconus, a cornea disorder.
