PHACOEMULSIFICATION CATARACT SURGERY WITH PROPHYLACTIC INTRAVITREAL BEVACIZUMAB FOR PATIENTS WITH COEXISTING DIABETIC RETINOPATHY: A Meta-Analysis.

PURPOSE: To evaluate the clinical effectiveness of intravitreal bevacizumab (IVB) injection combined with cataract surgery in the treatment of patients with cataract and coexisting diabetic retinopathy (DR).

METHODS

Pertinent comparative studies were identified through systemic searches of PubMed, EMBASE, and the Cochrane Controlled Trials Register up to March 1, 2016. Outcome measures included corrected distance vision acuity, central macular thickness, and progression of DR and maculopathy. A meta-analysis was performed using RevMan (Cochrane Collaboration, Oxford, United Kingdom).

RESULTS

Six studies describing a total of 283 eyes were identified. The meta-analysis results showed that corrected distance vision acuity measured at 1 month and 3 months after cataract surgery was significantly better in the IVB groups than in the control groups (P < 0.00001 and P = 0.01), whereas the corrected distance vision acuity at 6 months did not vary significantly between the 2 groups (P = 0.24). Similarly, the central macular thickness at 1, 3, and 6 months after surgery was significantly thinner in the IVB groups than in the control groups (P = 0.01, P = 0.0004, and P = 0.01, respectively). At 6 months, the progression of postoperative DR and maculopathy occurred more frequently in the control group than in the IVB group (P = 0.0001 and P < 0.0001, respectively).

CONCLUSION

Our meta-analysis indicates that cataract surgery combined with IVB seems to be an effective treatment in patients with coexisting DR in the short term (up to 6 months). More randomized, prospective, and large-sample-sized trials are needed to evaluate the long-term effects of IVB at the time of cataract surgery in patients with DR.
