Abstract Background and objectives This study aimed to investigate the impact of the possible prognostic factors for postsurgical success on visual acuity (VA) in traumatic cataract patients. Materials and methods The files of 92 patients (19 women[20.6%]–73 men[79.4%], 44 right–48 left total 92 eyes) who underwent surgery for traumatic cataracts between 2004 and 2018 were retrospectively reviewed for preoperative and final corrected distance VA(CDVA), laterality of trauma, time of admission to a hospital after trauma(TAH), type of injury, location of the injury (zone 1 [corneal], zone 2 [corneal and scleral], zone 3 [scleral]), additional ocular injury, simultaneous or secondary surgery, surgical cataract techniques, and complications. Result Of the 92 patients enrolled in the study, the mean CDVA was improved from preoperative 1.95 ± 0.49 logMAR to postoperative 0.73 ± 0.72 logMAR.(p \ 0.001) In 36.7% of cases, the final CDVA was C 20/40; it was C 20/60 in 58.7%, C 20/ 200 in 73.9%, and C 20/400 in 94.5%. The strongest correlation was found between postoperative CDVA and preoperative CDVA (Pearson’s R = 0.969, p = 0.0001). No correlation was found between CDVA and age, sex, and laterality.

analysis showed a significant relationship between the increase in CDVA and TAH, trauma type and location, and surgical timing and techniques. The worst CDVA prognosis was found for patients with a zone 3 injury; patients with a zone 1 injury had the best prognosis. The prognosis is better for a closed globe injury than an open globe injury (p = 0.019). Early TAH was related to a better prognosis than lateradmissions. No difference was observed between simultaneous and secondary surgeries (p = 0.413) and surgical techniques (p = 0.12). Conclusion Postoperative CDVA is better in traumatic cataract patients with a better preoperative VA. Early hospital admission after trauma, closed globe, and zone 1 injuries are better prognostic factors than late hospital admission time, open globe, and zone 3 injuries.

Introduction Ocular trauma is among the most well-known causes of unilateral blindness in individuals of reproductive age; its incidence peaks in adolescence, early adulthood, and in the 6th and 7th decades of life [1, 2]. It is observed 3 to 5 times more frequently in males than
