Cataract surgery in herpes simplex virus ocular disease.

Abstract

To investigate the outcomes and complications associated with cataract surgery in eyes with herpes simplex virus (HSV)-related anterior segment ocular disease. Public tertiary center in Auckland, New Zealand. Retrospective observational cohort study. Clinical records of patients diagnosed with HSV-related keratitis and/or anterior uveitis who underwent subsequent cataract surgery in the affected eye were reviewed. Main outcomes measured were visual outcome, complications, and recurrence. 37 eyes of 37 patients were included. Intraoperative complications occurred in 1 patient (2.7%) with iris prolapse. Keratitis or uveitis recurred postoperatively in 17 patients (45.9%) 8 patients (22.5%); 22.5% experienced recurrences in the first year postoperatively. 1 case (2.7%) of postoperative cystoid macular edema and 1 (2.7%) postoperative endophthalmitis occurred. Corrected distance visual acuity at 3 months was >20/50 in 21 patients (70.0%), 20/50 to 20/200 in 4 patients (12.9%), and ≤20/200 in 6 patients (19.4%). Vision improved in 26 eyes (83.9%) and worsened in only 1 eye (3.2%). Risk for recurrent inflammation was associated with a greater number of recurrences prior to surgery (hazard rate [HR] 1.31), time quiescent prior to surgery (HR 0.48), and iris transillumination defect at preoperative assessment (HR 57.66). Cataract surgery in eyes with previous HSV disease may improve visual acuity for most of the eyes but, overall, carries a guarded prognosis, particularly in eyes with corneal scarring. There is a significant risk for recurrent inflammation in the first year postoperatively. If possible, surgeons should ensure a period of disease quiescence prior to surgery.
