Made-to-Order Multifocal Contact Lens Trial
Would a 'tailor made' made-to-order multifocal lens perfor better than the equivalant widely prescribed off-the-shelf alternative? A few statistically signifianct differences were found for visual acuity and subjective vision and the overall performance of 'tailor made' lens was much better than off-the-shelf alternative. These aspects could be leveraged in a marketing campaign among contact lens practices seeking to have better overall success with multifocal soft conact lenses. 08/01/2017 Update: This trial has now completed and closed with report issued to sponsor.
Multifocal Contact Lens Trial (two separate trials)
We are looking for subjects who are over 42 and require different prescriptions for distance and near, bifocal/varifocal glasses, two pairs of glasses, removes distance glasses to read, glasses over contact lenses to read or monovision contact lenses. The object of the clinical trial is to determine if vision with contact lenses changes over a time period. Subjects who complete the clinical trial and are successful with the sponsor's lenses will be offered 3 months lenses free-of-charge (approx value £150.00). The subjects would be prescribed one or two pairs of lenses to wear for a week, normally three to four practice visits will be required. 05/05/2017 Update: Both of these trials has now completed and closed with report issued to sponsor. 25/03/2017 Update: Both of these trials have now completed and closed.
