Dear Editor,

Thank you very much for your kind remind and helps! We are also grateful for the efforts that editors have done for the manuscript. However, we are sorry that we have to withdraw the submission of our paper (Manuscript Number, CLINICALGROUP-14-316: Evaluation of intracameral cefuroxime injection for endophthalmitis prophylaxis following cataract surgery in a China ophthalmology department during 2009-2013). The reason is that, after careful consideration, we feel that we have not yet studied our work completely and have some difficulties to add additional explanations in the revised paper quickly. We will pay much time to evaluate some data and then plot them in the revised paper. We are very sorry that we have to make this decision and continue our investigation of this work further. All authors declare no conflicts and sign as below. We appreciate the reviewers very much for their careful work and helpful suggestions. Thanks again!
