Avastin or Lucentis?

My mom had an appointment with her ophthalmologist this morning, it was her routine check-up after having cataract and glaucoma surgery last year followed by capsulotomy procedure three months ago. She’s been worried because her vision becomes blurry lately.

After seeing her OCT (optical coherence tomography) test, the ophthalmologist said she had an AMD (Age-related Macular Degeneration) disease and had to be treated with avastin or lucentis injection. The difference? Avastin costs $200 while Lucentis costs $1100. I don’t have time to check further deep about those drugs yet, when I agreed to have a lucentis injection for my mom. Hopefully I will get more information before the procedure tomorrow.
