Study Details

Study Description

Brief Summary

This study will determine how multifocal contact lens correction affects symptoms of discomfort and asthenopia in a group of myopic contact lens wearers in the non-presbyopic age range (ages 30-40 years).

Condition or Disease Intervention/Treatment Phase
  • Device: Multifocal Contact Lens
  • Device: Single Vision Contact Lens
N/A

Detailed Description

The purpose of this study is to determine how multifocal contact lenses affect contact lens comfort in non-presbyopic contact lens wearers. Current soft contact lens wearers who have symptoms of discomfort in their contact lenses will be recruited. Each subject (n = 84) will wear a single vision soft contact lens (Ultra single vision spherical lens) for two weeks and a low add power multifocal (Ultra for Presbyopia) for two weeks. Half of the subjects will wear the single vision lens first, and half of the subjects will wear the multifocal lens first. Initial lens group will be chosen randomly. Subjects will complete surveys that assess their vision and comfort which each lens, and ocular surface and accommodative/binocular vision status will be evaluated at the initial dispense and after wearing each lens for two weeks.

Outcome Measures

Primary Outcome Measures

  1. Contact Lens Dry Eye Questionnaire-8 (CLDEQ-8) Score [Baseline and after 2 weeks of contact lens wear with each study lens (single vision and multifocal)]

    After wearing each lens type (single vision and multifocal) for 2 weeks, subjects will complete the CLDEQ-8, a survey that assesses symptoms of contact lens discomfort, to reports their symptoms of discomfort with each lens type. CLDEQ-8 scores with the multifocal will be compared to CLDEQ-8 scores of the single vision lens and the subjects' habitual contact lenses to determine if the multifocal improved comfort. Min-Max CLDEQ-8 range: 0-37 points Higher point values indicate more/worse symptoms
