Cataract surgery in chronic Stevens-Johnson syndrome: aspects and outcomes.

Abstract

To assess the outcome of cataract surgery in patients with chronic sequelae of Stevens-Johnson syndrome (SJS). <i>Setting</i>: Tertiary eye care centre in South India. Retrospective, non-comparative, consecutive, interventional case series. <i>Study period</i>: March 2003 to May 2014. Of the 1662 consecutive patients with SJS, 32 patients (40 eyes) with chronic sequelae of SJS who underwent cataract surgery were included. The main outcome measures were best-corrected visual acuity (BCVA) and ocular surface stabilisation. The visual acuity was expressed with reference to the logMAR. The study included 12 men (37.5%) and 20 women (62.5%). 8 patients (25%) had bilateral cataract surgeries. The median preoperative BCVA was 1.61 (IQR, 0.80 to 2.78) (only perception of light in three eyes). The median BCVA in the immediate postoperative period was 0.60 (IQR, 0.30 to 1.48) (perception of light in an eye) which was significantly different from the preoperative BCVA (p<0.0001). The median BCVA achieved was 0.30 (IQR, 0.00 to 0.80), suggesting further improvement. Median time taken to achieve this postoperatively was 1.5 months (IQR, 8 days to 3 months). The median BCVA during the last follow-up was 0.48 (IQR, 0.18 to 1.00). The preferred type of cataract surgery was phacoemulsification. Ocular surface condition remained stable in 35 eyes (87.5%). Ocular surface breakdown in four eyes (10%) was managed appropriately. Cataract surgery outcome can be visually rewarding in chronic sequelae of SJS provided ocular surface integrity is adequately maintained preoperatively and postoperatively.
