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. |
