Effect of secondary intraocular lens implantation in traumatic cataract with posterior capsular rupture

Abstract

Objective To explore the effect of secondary intraocular lens (IOL) implantation in traumatic cataract with posterior capsular rupture.Methods 72 cases of traumatic cataract with posterior capsular rupture were divided into two groups:group A (36 eyes,36 cases) and group B (36 eyes,36 cases).Patients in group A were treated by traumatic cataract removal and primary IOL implantation.Patients in group B underwent traumatic cataract removal and secondary IOL implantation.The visual acuities and surgical complications were compared between two groups.Results There were 22 eyes (61.6％) in group A and 27 eyes (75.0％) in group B with visual acuities better than 0.5 at 8 weeks after surgery and the difference was statistically significant (x2 =8.175,P ＜ 0.05).The different degrees of inflammatory reaction were observed in two groups.The incidences of surgical complications in group B were much lower than that in group A (x2 =10.125,P ＜ 0.05).Conclusion The traumatic cataract with posterior capsular rupture treated by secondary IOL implantation can have better visual outcomes and less surgical complications compared with primary IOL implantation.
