Discussion on time and methods for intraocular lens implantation in traumatic cataract

Objective To investigate time and methods for intraocular lens implantation in traumatic cataract. Methods 52 cases(52 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. The wound was sutured primarily and 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 52 eyes, posterior chamber IOL implantation was done primarily in 35 eyes and 17 eyes received secondary posterior chamber IOL implantation.Results After surgery, visual acuity was 0.05 or better in 96.15% eyes, better than 0.3 in 67.31 % eyes, better than 0.5 in 36.54% eyes and better than 1.0 in 3.85% eyes.Conclusions For complicated traumatic cataract, with suitable surgical timing and control of intraoperative and postoperative complications, most patients could get better visual acuity and binocular vision recovery.
