纳入标准：

Inclusion criteria

1. Patients diagnosed with neovascular age-related macular degeneration, regardless of gender.
2. Aged between 50 and 89 years old.
3. Following prior anti-VEGF therapy in the study eye, SD-OCT assessment indicated a prior therapeutic response (defined as a reduction in central retinal thickness of <=50 micrometres from baseline or improvement in central fluid of <=30% at one week post-injection).
4. Subjects had received intravitreal injections of anti-VEGF agents within the eight months preceding screening, demonstrating inadequate response to at least four treatments (defined as increased central retinal thickness at one week post-injection compared to baseline and/or a loss of >=5 letters in best-corrected visual acuity (BCVA) relative to baseline or the highest BCVA achieved during treatment).
5. Recruited subjects had best-corrected visual acuity (BCVA) ranging from 20/400 to 20/63 (Snellen chart, corresponding to ETDRS letters 19 to 63).
6. Both eyes meet the inclusion criteria; the eye with poorer vision is selected for inclusion.
7. The study must clearly diagnose subfoveal choroidal neovascularisation (CNV) secondary to age-related macular degeneration (AMD). The CNV lesion area must be less than 10 disc areas, and the haemorrhagic area must constitute less than 50% of the total lesion area.
8. The degree of cataract formation does not affect the assessment of the fundus or the fitting of an intraocular lens.
9. Able to comply with all research procedures and follow-up appointments during the study period.
10. Female subjects of childbearing potential must have a negative urine pregnancy test at the screening visit, a negative serum pregnancy test result on day 8, and must consent to additional pregnancy testing during the study period.
11. Participants who are sexually active must agree to use contraception from the date of recruitment until 24 weeks after carrier administration. Should contraception need to be discontinued thereafter, this should be decided following discussion with the responsible physician.
12. Subjects must be willing and able to sign a written informed consent form.

排除标准：

1.研究眼存在除AMD以外其他原因所致的CNV或黄斑水肿。
2.AMD病灶中出血面积≥50%，或研究眼黄斑中心凹下方出血面积＞1.0mm²。
3.存在任何可能阻碍研究眼视力改善的病变，例如中心凹区域的纤维化、萎缩或视网膜色素上皮撕裂。
4.研究眼存在活动性视网膜脱离，或既往有视网膜脱离病史。
5.研究眼存在晚期青光眼。
6.研究眼存在任何可能增加受试者风险、需在研究期间接受药物或手术干预以预防或治疗视力丧失，或干扰研究操作或评估的疾病（由研究者判断）。
7.招募前12周内研究眼曾接受过眼内手术，或10周内接受钇铝石榴石激光后囊切开术。
8.招募前6个月内，研究眼曾接受抗VEGF治疗除外的其他玻璃体内治疗（如玻璃体内糖皮质激素注射或试验用产品）。
9.招募时研究眼已置入植入物（人工晶状体除外）。
10.招募前5年内曾患需接受化疗和/或放疗的恶性肿瘤。局限性基底细胞癌除外。
11.入组前30天内或试验用产品5个半衰期内曾接受过试验用产品。
12.曾参与其他基因治疗研究。
13.既往接受过已知可致视网膜毒性的治疗，或当前正在接受可能影响视力或具有已知视网膜毒性的药物（例如氯喹或羟氯喹）。
14.研究眼存在可能干扰手术操作的眼部或眼周感染。
15.近6个月内发生过心肌梗死、脑血管意外或短暂性脑缺血发作。
16.存在未控制的高血压（收缩压＞180 mmHg，舒张压＞100 mmHg）。
17.正在同时接受可能干扰眼部手术操作或术后愈合的治疗（由研究者判断）。
18.已知对雷珠单抗或其成分物过敏，或既往对AAV类药物存在过敏反应（由研究者判断）。
19.患有严重、慢性或不稳定的内科或精神疾病，经研究者判断可能危及受试者安全，或影响其完成全部评估及随访。

Exclusion criteria：

1. Investigate the presence of choroidal neovascularisation or macular oedema caused by factors other than age-related macular degeneration. 2. The haemorrhagic area within the AMD lesion is >=50%, or the haemorrhagic area beneath the fovea centralis in the study eye exceeds 1.0 mm². 3. Any pathological condition that may impede the improvement of visual acuity, such as fibrosis, atrophy, or retinal pigment epithelial detachment in the foveal region. 4. The eye under investigation exhibits active retinal detachment or a history of retinal detachment. 5. The eye exhibits signs of advanced glaucoma. 6. Investigate any existing conditions that may increase subject risk, necessitate pharmacological or surgical intervention during the study to prevent or treat vision loss, or interfere with study procedures or assessments (as determined by the investigator). 7. Subjects who had undergone intraocular surgery within the 12 weeks preceding recruitment, or who had received YAG laser posterior capsulotomy within the preceding 10 weeks. 8. Within the six months preceding recruitment, the study eye had received intravitreal treatment other than anti-VEGF therapy (such as intravitreal corticosteroid injections or investigational products). 9. At the time of recruitment, the eye under investigation must already have an implant (excluding intraocular lenses). 10. Recruitment excludes individuals who have had malignant tumours requiring chemotherapy and/or radiotherapy within the preceding five years. Excludes localised basal cell carcinoma. 11. Received the investigational product within 30 days prior to study entry or within five half-lives of the investigational product. 12. Has previously participated in other gene therapy research. 13. Previously received treatment known to cause retinal toxicity, or currently receiving medication that may affect vision or has known retinal toxicity (e.g., chloroquine or hydroxychloroquine). 14. Investigate whether any ocular or periorbital infections may interfere with surgical procedures. 15. Myocardial infarction, cerebrovascular accident, or transient ischaemic attack within the past six months. 16. Uncontrolled hypertension is present (systolic blood pressure > 180 mmHg, diastolic blood pressure > 100 mmHg). 17. Currently undergoing treatment concurrently that may interfere with ocular surgical procedures or postoperative healing (as determined by the investigator). 18. Known hypersensitivity to rituximab or any of its constituents, or a history of allergic reactions to AAV-based medicinal products (as determined by the investigator). 19. Suffering from severe, chronic, or unstable medical or psychiatric conditions which, in the investigator's judgement, may jeopardise the subject's safety or impair their ability to complete all assessments and follow-up.

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture：	Data collection utilises a standardised electronic case report form. Key data undergoes double-entry verification before input, followed by cross-checking and error correction with documentation of the rectification process. Statistical specialists conduct logical data verification, with researchers providing reasonable explanations for outliers. Unexplained anomalies necessitate repeat testing for validation. Paper records are archived in the dedicated filing cabinet of the hospital's GCP office, whilst electronic data is backed up on secure internal servers.
