Scientific titleA quantitative study comparing hard and soft contact lenses to spectacles on changes in nystagmus oscillations
Study hypothesisOur hypothesis is that nystagmus can be improved with contact lens wearing. The specific research questions are:
1. Do contact lenses reduce nystagmus and improve vision compared to spectacle wearing?
2. Are hard contact lenses better than soft contact lenses for reducing nystagmus and improving vision in nystagmus?
Ethics approval(s)Leicestershire, Northamptonshire and Rutland Research Ethics Committee 1, 06/07/2010, ref: 10/H0406/40
ConditionNystagmus
InterventionPatients will take part in the trial for a total duration of 8 weeks. This will comprise of 2 weeks of spectacle wear followed by 2 weeks of hard or soft contact lens wear. The next 2 weeks the patients will be wearing the opposite type of contact lens to those prescribed previously and then finally 2 weeks of spectacle wear again. Details of each visit are below:

Visit 1: Optimal refraction determined and glasses prescribed and contact lenses fitted and ordered followed by EXAMINATION 1
Day 1 - 14: Spectacle wearing (minimum of 14 days)
Visit 2 (day 14): EXAMINATION 2 followed by contact lens type 1
Day 15 - 28: Contact lens type 1 wearing
Visit 3 (day 28): EXAMINATION 3 followed by contact lens type 2
Day 29 - 42: Contact lens type 2 wearing
Visit 4 (day 42): EXAMINATION 4 followed by spectacle wearing
Day 43 - 56: Spectacle wearing
Visit 5 (day 56): EXAMINATION 5
Intervention typeOther
Primary outcome measureChanges in nysatgmus intensity measured with eye movement recordings, measured at baseline, day 14, day 28, day 42 and day 56.
Secondary outcome measuresMeasured at baseline, day 14, day 28, day 42 and day 56:
1. Changes in LogMAR (chart) visual acuity at 4M (with head free)
2. Changes in LogMAR (chart) visual acuity at 0.4M (with head free)
3. Change in gaze dependant visual acuity at 4M
4. Change in nystgamus intensity, NAFX function and reading speed will be evaluated from the eye movement recordings at different fixation points across the horizontal plane
5. Subjective changes in visual function evaluated with the VFQ25
