The surgical treatment of traumatic cataract with posterior capsule rupture(PCR)

Objective To investigate the timing,the technique and the principle of intraocular lens(IOL) implantation in traumatic cataract with posterior capsule rupture(PCR) in penetrating cornea injury. Methods 53 eyes of traumatic cataract with PCR in penetrating cornea injury were analyzed retrospectively.All eyes were operated with cataract surgery in 4-11 days after tauma.The different methods of phacoemulsification,cataract extraction,lensectomy with vitrectomy were performed according to ocular conditions.39 eyes(39/53,73.6%) implanted IOL immediately and other 12 eyes were(12/59,26.4%) secondary IOL implantation.The best corrected visual acuity(BCVA),position of IOL,conditions of vitreous and retina complications of surgery were followed routinely postoperatively. Results At 6 months,BCVA were worse than 0.1(3/53,5.6%) in 3 eyes,0.1-0.25 in 13(13/53,24.5%) eyes,0.3-0.6 in 28(28/53,52.8%)eyes,and better than 0.6 in 9(9/53,17.1%)eyes.The complications were eccentric of the lens in 3 eyes,clamp of the lens in 2 eyes and subluxation of the lens in 1 eye. Conclusions Traumatic cataract with PCR in penetrating cornea injury should be operated with appropriate surgical methods in proper time after trauma according to the situation of anterior and posterior segment.
