Abstract

Purpose:

To describe clinical presentations and comparative outcomes of primary versus deferred intraocular lens (IOL) explantation in delayed-onset endophthalmitis.

Methods:

In this retrospective study, a total of 77 eyes of 77 patients that were diagnosed clinically as delayed-onset endophthalmitis and underwent IOL explantation from January 1990 to January 2018 were included undiluted vitreous biopsy and IOL were subjected to microbiologic evaluation. Duration of symptoms, presenting visual acuity, organisms isolated, time to IOL explantation, time to endophthalmitis, resolution after explantation, number of repeat intravitreal injections, and final visual acuity were compared in the primary and the deferred IOL explantation groups.

Results:

There were primary and deferred IOL explantations. Interval between inciting event and endophthalmitis, between onset of symptoms to presentation, total follow-up, complication rate, and final visual acuity was comparable between the two groups. Median time to IOL explantation in the deferred group was 70 days. Between the primary and deferred IOL explantation groups the number of repeat intravitreal injections was 0.58 ± 0.86 and 2.62 ± 1.78 respectively, (P < 0.0001, 95% confidence interval, CI 2.00-2.22); the number of days to resolution after IOL explantation was 35.16 ± 14.26 and 55.5 ± 8.24 respectively, (P < 0.0001, 95% CI 15.22-25.45).

Conclusion:

Early IOL explantation in delayed-onset endophthalmitis causes faster clinical resolution and reduces the number of repeat intravitreal injections. Final visual improvement, however, may be unaffected.
