Primary cataract extraction and intraocular lens implantation in penetrating ocular trauma.

PURPOSE

To analyze the postoperative outcome and complication rate after cataract extraction or lensectomy with primary intraocular lens (IOL) implantation for penetrating traumatic cataract.

DESIGN

Retrospective, nonconsecutive, noncomparative case series.

METHODS

We retrospectively reviewed the files of 21 patients who were admitted to our departments because of traumatic cataract with corneal or scleral laceration caused by penetrating trauma with or without intraocular foreign body (IOFB) from 1992 through 1997. Lens aspiration or manual extracapsular cataract extraction with primary IOL implantation was performed in all patients. Removal of an IOFB was performed in eight patients.

MAIN OUTCOME MEASURES

Final visual acuity and deviation of actual refraction from emmetropia and from expected postoperative refraction.

RESULTS

The mean follow-up was 20.4 months. Fourteen eyes (67%) achieved final visual acuity of 20/40 or better, 95% obtained 20/60 or better final visual acuity, and all eyes achieved 20/100 or better final visual acuity. Major causes of limited visual acuity were central corneal scar and central retinal injury. Eleven eyes (57%) experienced secondary cataract and underwent neodymium:yytrium-aluminum-garnet capsulotomy.

CONCLUSIONS

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