Outcomes of cataract surgery in eyes with previous herpes zoster ophthalmicus

To report the outcomes of cataract surgery in eyes with previous herpes zoster ophthalmicus (HZO).

Kellogg Eye Center, University of Michigan, Ann Arbor, Michigan, USA.

Retrospective case series.

Eyes with a history of HZO that had phacoemulsification and intraocular lens implantation were reviewed. The information analyzed included the ophthalmologic history, visual acuity, preoperative and postoperative adjunct treatments, and complications. Analysis of the mean corrected distance visual acuity (CDVA) at 1 month, 1 year, and the last follow-up was performed.

Twenty-four eyes were evaluated. The mean CDVA improved from 20/112 (0.75 logMAR ± 0.63 [SD]) preoperatively to 20/53 (0.42 ± 0.56 logMAR) 1 month postoperatively (P = .007) and 20/44 (0.34 ± 0.55 logMAR) at 1 year (P = .052) but decreased to 20/71 (0.55 ± 0.72 logMAR) by last follow-up (P = .605 versus preoperative CDVA). Eleven patients (45.8%) had recurrent keratouveitis after the first episode, 5 before cataract surgery and 6 after cataract surgery. Three had penetrating keratoplasty for worsening corneal opacification. Two patients had tractional retinal detachment from chronic uveitis and required vitrectomy and retinal repair.

Visual recovery after cataract surgery in HZO might be compromised by chronic factors such as ocular surface disease and keratouveitis. Despite long quiescent waiting periods before surgery and aggressive preoperative and postoperative maintenance therapy, visual improvement might be hindered by the inherent pathology associated with HZO. Nevertheless, with careful patient selection, reasonable visual improvement can be achieved.
