8. Aphakia (excluding intraocular lens) or posterior lens capsule rupture (except for YAG laser posterior capsulotomy after intraocular lens implantation more than 1 month from screening) in the study;
9. Afferent pupil defect (APD) in the study eye;
10. Patients have received anti-VEGF(vascular endothelial growth factor ) treatment within 6 months before screening, such as ranibizumab, bevacizumab, conbercept, etc in any eye or the whole body;
11. Use of intraocular or systemic corticosteroids within 3 months before screening, or use of periocular corticosteroids within 1 month;
12. Any active intraocular or periocular infection (for example: blepharitis, infectious conjunctivitis, keratitis) in either eye;
13. Any history of glaucoma;
14. Any evidence of pseudocapsular exfoliation syndrome in either eye;
15. A history of vitreous hemorrhage within 3 months before screening in either eye;
16. Any systemic drug (currently in use or may need to use) could cause lens toxicity or retinal toxicity, such as desferrioxamine, chloroquine/hydroxychloroquine, tamoxifen, phenothiazine, ethambutol, etc.;
17. History of allergy to the therapeutic or diagnostic drugs used in the research protocol, including allergies to the test articles;
18. Diabetic subjects with diabetic retinopathy or glycosylated hemoglobin> 9%;
19. Any history of surgery within 1 month before screening, and/or any currently unhealed wounds, ulcers, fractures, etc.;
20. Any infectious disease requiring systemic treatment (oral, intramuscular or intravenous) during screening;
21. History of a medical condition, including myocardial infarction, unstable angina pectoris, coronary revascularization, cerebrovascular accidents (including TIA), other thromboembolic diseases (such as thromboembolic angiitis, pulmonary embolism, deep vein thrombosis, portal vein thrombosis, etc.), New York Heart Association (NYHA) grade ≥ Grade II cardiac insufficiency, severely unstable ventricular arrhythmia within 6 months before screening;
22. History of diffuse intravascular coagulation and obvious bleeding tendency (such as hemoptysis, hematemesis, severe purpura, etc.) within 3 months before screening, or use of anticoagulant and antiplatelet therapy other than aspirin/NSAIDs within 14 days before screening;
23. Subjects with systemic immune diseases;
24. Poorly-controlled blood pressure (defined as: after receiving antihypertensive drugs, the subject's systolic value ≥160 mmHg or diastolic value ≥100 mmHg at seat);
25. Any uncontrollable clinical disease (such as serious mental, respiratory and other system diseases and malignant tumors);
26. Abnormal liver and kidney function (ALT, AST≥2.5 times the upper limit of normal; total bilirubin≥1.5 times the upper limit of normal; Crea, urea/urea nitrogen≥1.2 times the upper limit of normal);
27. Abnormal blood coagulation function (prothrombin time> upper limit of normal value 3 seconds or activated partial thromboplastin time> upper limit of normal value 10 seconds);
