简要总结
Viscoelastic is a powerful tool in pars plana vitrectomy(PPV) surgery relative to perfluorocarbon liquid because it has the properties to dilate and engorge the retina and restore the detached retina to its original position. We intend to explore whether the use of viscoelastic to assist PPV surgery can help improve surgical efficiency, reduce tissue damage, and improve the outcomes of the patients.
