Extended-Wear Silicone Hydrogel Soft Contact Lenses in the Management of Moderate to Severe Dry Eye Signs and Symptoms Secondary to Graft-Versus-Host Disease

Abstract

To determine the safety and efficacy of the Focus NIGHT & DAY (CIBA Vision, Duluth, GA) silicone hydrogel contact lens in the management of refractory, moderate to severe dry eye signs and symptoms secondary to graft-versus-host disease (GVHD). Seven patients with GVHD and moderate to severe dry eye disease as determined by the Ocular Surface Disease Index (OSDI) questionnaire were fitted with a near plano Focus NIGHT & DAY soft contact lens (SCL) used on a 7-night continuous-wear basis. Visual acuity, objective measures of dry eye disease (i.e., Schirmer I, tear breakup time, and corneal fluorescein staining), and OSDI scores were compared before SCL wear and after 1 week and 1 month of SCL wear. There was significant improvement in subjective assessment of dry eye symptoms (initial vs. 1-month OSDI score, 76.8 +/- 13.6 vs. 31.2 +/- 17.8, P<0.0005, paired t test). In addition, patients had significant improvement in best-corrected visual acuity after 1 month of SCL wear (initial vs. 1-month logMAR visual acuity for the right eye, 0.23 +/- 0.050 vs. 0.04 +/- 0.027, P<0.007; initial vs. 1-month logMAR visual acuity for the left eye, 0.22 +/- 0.049 vs. 0.04 +/- 0.020, P<0.007, analysis of variance, Dunnett post hoc). There were no significant changes in results of Schirmer I testing, corneal fluorescein staining, or tear breakup time. No adverse events or complications of SCL wear were observed. The Focus NIGHT & DAY contact lens can improve subjective dry eye symptoms and visual acuity in patients with refractory dry eye disease secondary to GVHD.
