A clinical study on the surgery indication and IOL selection after complicated global penetrating injury.

Objective To study the indication and the intraocular lens (IOL) selection after complicated global penetrating injury. Clinical results were evaluated. Methods 78 eyes (78 patients) with traumatic cataract and vitreoretinopathy after complicated global penetrating injury were treated with pars plana vitrectomy, 12 eyes with primary IOL implantation, 57 eyes with secondary anterior chamber IOL implantation and 9 eyes with secondary black diaphragm IOL implantation. The mean follow-up after IOL placement was 12. 8 months. Results The visual acuity afte IOL implantation was much elevated than that after trauma. It was closely related with the traumatic degree of posterior segment. No retinal detachment and bullous keratopathy were observed. Conclusion It is safe and effective to implant IOL for traumatic cataract after complicated global penetrating injury if an optimal operative treatment and an optimal type of IOL are selected.
