The association of comfort and vision in soft toric contact lens wear

PurposeThis work set out to investigate if there was an association between subjective comfort and both measured vision during the use of contemporary daily disposable soft toric contact lenses.MethodsThirty-eight habitual lens wearers wore each three lenses for one week in a prospective, crossover, randomised, single-masked study. The following clinical measures were recorded at dispensing follow-up visits: biomicroscopy scores, fitting (including rotation rotational stability), high low contrast visual acuity, quality ocular surface comfort. Subjective scores collected using 0–10 numerical grading scales. Comfort analysed linear regression model with age, sex, visit, phase crossover (‘phase’), type, rotation, stability, cylinder power as factors interest then refined backward stepwise regression.ResultsThirty six participants (31.1 ± 13.5 years) completed found be associated (F = 127.0 ; p < 0.0001), 7.2; 0.001) type 4.9; 0.009). Greater observed greater scores. Visual acuity not statistically significant model.ConclusionThis suggests that symptoms discomfort may more intense is also perceived compromise lenses. There stronger positive correlation compared acuity.
