The investigation on surgical of timing traumatic cataract with capsula broken and clinical effect of secondary intraocular lens implantation

Objective To investigate the surgical timing of traumatic cataract with capstla broken and clinical effect of secondary intraocular lens implantation. Methods In 44 patients (44 eyes) of traumatic cataract with capsula broken, the catarat extraction and IOL implantation were performed on different time, according to the age, type and extent of trauma, degree of inflammation and accompanying injuries. In principle, corneal wound need prompt surgical intervention. If cortex extruded into anterior chamber or secondary glaucoma occurred, the surgery was done in emergency. For severe ocular inflammation, surgical intervention was considered until inflammation was controlled. 44 eyes underwent subsequent IOL implantation in 1 month. Results Follow-up visit after operation was 1 to 3 months. Best-corrected visual acuity ( BCVA) was 0.05 -0.08 in 3 eyes (6.82％) ,0. 1 -0. 2 in 6 eyes ( 13.64％ ), 0.3 -0.4 in 14 eyes (31.82％ ), 0.5 -0.8 in 17 eyes (38.64％), better than 1.0 in 2 eyes (4.54％). Conclusions The vision of patients with capsula broken is improved after surgical intervention. Appropriate surgical timing is important for patients suffering traumatic cataract with capsula broken to achieve finsl best-corrected visual acuity and decrease the postoperative complications.
