The investigation on surgical timing of traumatic cataract

Objective To investigate the surgical timing of traumatic cataract. Methods 213 cases (213 eyes) of traumatic cataract received cataract extraction and intraocular lens implantation(IOL) in different time according to the age, type of trauma, degree of inflammation and accompanying injuries. In principle, all surgeries (especially for children) were performed as early as possible. In patients with corneal wound, the wound was sutured and primary or secondary cataract extraction was done according to the condition. For small capsule rupture or contusive cataract, the surgery was done until cortex became cloudy totally. For severe ocular inflammation, surgery was done until inflammation was controlled for 1-2 weeks. If cortex expanded, extruded and contacted with corneal endothelium or induced severe inflammation or secondary glaucoma, the surgery was done in emergency. In the 213 eyes, posterior chamber IOL implantation was done primarily in 187 eyes and 26 eyes received secondary posterior chamber IOL implantation. Results After surgery, visual acuity was 0.05 or better in 99.06% eyes, better than 0.3 in 87.79 % eyes, than 0.5 in 71.36% eyes and than 1.0 in 16.90% eyes. Conclusion For complicated traumatic cataract, suitable surgical timing, in time control of intraoperative and postoperative complications, most patients could get better visual acuity and binocular vision recovery.
