[Primary implantation of posterior chamber lenses after traumatic cataract peneration]

PURPOSE

To analyze the postoperative outcome and complication rate after phacoemulsification, lens aspiration or lensectomy with primary intraocular lens (IOL) implantation after traumatic cataract penetration.

METHODS

We retrospectively reviewed the data of 15 patients who were admitted to our hospital from 1997 to 2001 because of traumatic cataract with corneal laceration with and without intraocular foreign body (IOFB). In all patients phacoemulsification, lens aspiration or lensectomy and primary IOL implantation were performed. Removal of IOFB was performed in 6 patients.

RESULTS

The mean follow-up was 19.6 months, 8 eyes (53%) achieved a final visual acuity of 20/40 or better and 12 eyes achieved 20/100 or better final visual acuity. One patient (final visual acuity=1/40) had an additional macular pathology. Due to irregular astigmatism two patients achieved a final vision of less than 20/100. Major causes of limited visual acuity were central corneal scars and in one patient a photopic maculopathy. Four eyes (25%) developed secondary cataract and underwent YAG laser capsulotomy. In one patient PVR retinal detachment had to be treated by pars-plana vitrectomy with silicone oil tamponade.

CONCLUSIONS

Primary implantation of posterior chamber lenses after penetrating ocular trauma is associated with a favourable visual outcome and a low rate of postoperative complications.
