Criteria

Inclusion Criteria:

1. Patients give fully informed consent and are willing and able to comply with all study procedures.

2. In the study eye:

There are primary or recurrent subfoveal or parafoveal active choroidal neovascularization (CNV) lesions secondary to wAMD.

The criterion of active CNV should meet at least one of following three conditions :

• fresh bleeding;

• neurosensory detachment showed on optical coherence tomography(OCT);

• leakage showed on fundus fluorescein angiography (FFA).

3. BCVA in study eye < 19 letters (approximately 20/400 Snellen equivalent).

Exclusion Criteria:

1. Past or existing non-exudative AMD in study eye decided by investigator that have affected macular detection or central vision;

2. Subretinal hemorrhage in study eye and bleeding area ≥6 disc areas;

3. History of vitreous hemorrhage within last month;

4. The maximum diameter of scar and fibrosis area ≥500μm at subfoveal in study eye;

5. Photodynamic therapy (PDT) or drug treatment of CNV within last 6 months in study eye, or anti-vascular endothelial growth factor (VEGF) therapy in fellow eye within last month;

6. History of glaucoma in study eye;

7. Aphakia (excluding artificial lens) in the study eye.
