Outcomes and longitudinal trend of traumatic cataract wound dehiscence in patients with blunt ocular injury.

Longitudinal trends on traumatic cataract wound dehiscence are scant. In this study, we present the characteristics of traumatic cataract wound dehiscence using 15 years of longitudinal trend in one of the largest medical centers in Taiwan for a period when cataract surgeries were gradually shifting from extracapsular cataract extraction (ECCE) to phacoemulsification. All patients with a prior cataract surgery who suffered from blunt open globe trauma between 2001 and 2015 at a tertiary referral center in Taiwan were included. The number of cases per year; type of prior cataract surgery; visual acuity (VA); mechanism and place of injury were analyzed. The risk factors associated with final VA were investigated in patients followed up for ≥ 1 month. Seventy-six eyes of 75 patients were included and all of them were traumatic cataract wound dehiscence with a prior ECCE (65 eyes) or phacoemulsification. The most common mechanism and place of injury was fall and at home in both cataract surgical types. The mean log of the minimal angle resolution (logMAR) of final VA was 2.15 ± 0.88 (ECCE) and 1.61 ± 0.83 (phacoemulsification) (P = .026). The most significant risk factors associated with worse final VA were retinal detachment at the initial visit and low ocular trauma score (both P < .001). Long-term visual outcome of phacoemulsification wound dehiscence was better than that of ECCE wound after a blunt trauma.
