Objective: To study final visual outcome in cases of surgically treated traumatic cataract caused by penetrating variety of Open globe group classified according to Birmingham Eye Trauma Terminology System. Material and Methods: We enrolled patients with specific inclusion criteria, examined their eyes to review the co-morbidities due to trauma, performed surgery for traumatic cataracts, and implanted a lens. The patients were re-examined 6 weeks postoperatively. We divided the cases of traumatic cataract into two groups, the open globe (Group 1) and closed globe (Group 2) groups, We further sub divided open globe in to sub groups of open globe injuries, out of which we studied penetrating sub group of ocular trauma based on the Birmingham Eye Trauma Terminology System (BETTS) and compared the determinants of visual acuity. Result: Our cohort of 687 eyes with traumatic cataracts included 496 eyes in Open globe and 191 in closed globe group. Six weeks postoperatively, Overall 373 (54.3%) eyes gained final visual acuity >20/60. Our study had 422 (61.4%) penetrating injury cases out of them 61.4% regained final visual acuity>20/60. Visual outcome was significantly better when compared amongst penetrating subgroup of open globe injury and other subgroups of BETTS. Conclusions: Penetrating subgroup of open globe injury has a favorable prognosis for satisfactory (>20/60) visual recovery after management of traumatic cataracts
