The anterior capsule holding technique in IOL implantation for traumatic cataract

Objective To investigate the clinical effect of the anterior capsule holding of intraocular lens for traumatic cataract with large area of posterior capsule rupture. Methods All the 96 eyes of 96 patients with traumatic cataract caused by corneal penetrating injury received corneal suturing first and then cataract extraction and lens implantation. All the cases were divided into three groups according to the severity of anterior and posterior capsule rupture and lens fixation methods. Group A, posterior capsule holding, 68 eyes; group B , the anterior capsule holding, 12 eyes; and group C, ciliary sulcus fixation, 20 eyes. The follow-up time was 6 to 36 months. The surgical effect and postoperative complications were observed. Results At the 6 months after the surgery, the best corrected visual acuity (BCVA) better than 0.3 was in 31 eyes (48.44%) in group A, in 6 eyes (50.00%) in group B and 6 eyes (30.00%) in group C. There were no any serious operative complications in three groups. The postoperative complications in group B included corneal edema in 3 eyes (25.00%), uveal inflammation in 3 eyes (25.00%), and no lens decentration, pupil block, artificial lens dislocation, posterior capsule opacity (PCO) or retinal detachment (RD) occurred. Conclusion The intraocular lens implantation by anterior capsule holding for traumatic cataract with large area of posterior capsule rupture caused by corneal perforation is simple and effective in the cases in whom the continuous circular capsulorhexis can be performed successfully.
