AIM:To observe the effect of multi-surgery for the treatment of severe traumatic hyphema and investigate surgical techniques.METHODS:Twenty-three cases (23 eyes) with severe traumatic hyphema underwent corneal incision and irriga-tionaspiration with ultrasound emulsification equipment or bimanual system to draw-off anterior chamber hyphema. During the operation,the viscoelastics was used to separate the blood clots and to stop bleeding. Anterior chamber,intraocular pressure and visual acuity were observed postoperatively.RESULTS:Twenty-one eyes succeeded in the first surgery,and the other 2 eyes failed. Visions less than 0.05 were in 5 eyes(22%),0.05~0.3 in 11 eyes(48%),and more than 0.3 in 7 eyes(30%).CONCLUSION:Multi-surgery in different hyphema may achieve better outcome.
