Abstract
Purpose: :
To evaluate the visual outcome, surgical approach and accuracy of biometry in patients with traumatic cataract after penetrating or non-penetrating ocular trauma.
Methods: :
In a retrospective study, 31 patients with traumatic cataract were analyzed for type of trauma (extent of ocular tissue involvement), surgical procedures, biometry prediction error and visual outcome. Biometry prediction errors for penetrating and non-penetrating trauma were compared.
Results: :
Twenty nine of 31 patients were male. Average age at time of trauma was 30 years. Twenty-two patients had a penetrating trauma, with concomitant vitreous loss in 9 patients. Eighteen patients had additional iris trauma and in 11 cases iris reconstruction was necessary. In 7 out of 10 patients with zonulolysis a capsular tension ring was used. The mean visual improvement after cataract extraction and IOL implantation was -1.12 LogMar. Twenty-six eyes (84%) achieved final best-corrected visual acuity of 0.3 LogMar or better. The mean biometry prediction error was 0.84 diopter (SD=0.63) in patients with penetrating trauma compared to 0.63 diopter (SD=0.37) in patients with non-penetrating trauma (p=0.360). Fifteen eyes (69%) and 7 (88%) were within 1 diopter of the target refraction in the group of penetrating versus non-penetrating trauma respectively.
Conclusions: :
The majority of patients with ocular trauma were young males. Visual rehabilitation after surgical intervention of ocular trauma with traumatic cataract was excellent. There was no significant difference in biometry prediction error between patients with or without penetrating trauma.
