Comparative Evaluation of Corneal Staining With Balafilcon A Lenses and Two Multi-Purpose Solutions...
MyopiaHyperopia1 moreA new multi-purpose solution (MPS)was clinically evaluated against Opti-Free RepleniSH MPS at specific time points over the course of four days. The study was conducted with PureVision lenses.
Corneal and Conjunctival Sensitivity and Staining Study
MyopiaHyperopiaThe primary objective of this study is to compare subjective symptoms and ocular health in a group of individuals who are currently wearing soft contact lenses on a daily wear basis, after a short period of no lens wear and during the time course when using differing care regimens.
APIOC for Presbyopia and APIOC for Presbyopia With Astigmatism
PresbyopiaMyopia2 moreVision and comfort, both objective and subjective, will be assessed for single vision contact lens wearers for either the APIOC™ for Presbyopia or the APIOC™ for Presbyopia Astigmatism contact lenses.
Pilot Clinical Performance of a Silicone Hydrogel Lens for Up to Six Nights of Extended Wear
Refractive ErrorsMyopia1 moreThe purpose of this clinical study is to evaluate the on-eye performance of an investigational soft contact lens compared to a commercially available soft contact lens when worn continuously for up to 1 week.
Bilateral Dispensing Study of Fanfilcon A Toric Versus Enfilcon A Toric Lenses
MyopiaHyperopia1 moreBilateral dispensing clinical trial of fanfilcon A toric lens verses enfilcon A toric lens over two weeks.
Multicenter Evaluation of Safety and Effectiveness of Presbyopic LASIK for Hyperopes
PresbyopiaHyperopiaThe Presbyopia Algorithm subject to this study has been specifically developed to prospectively generate a treatment file for the Technolas 217z100 laser that will provide Presbyopia correction among eyes with primary hyperopia or hyperopic astigmatism (distance correction). The treatment algorithm provides a bilateral, multifocal ablation with a center near addition, thereby allowing good focus over a range of object distances.
