Multifocal Contact Lenses for Presbyopia
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to assess satisfaction with two types of soft multifocal contact lenses: Clariti® 1 Day Multifocal 3 Add and Proclear® 1 Day Multifocal. It targets individuals with presbyopia, a condition where aging affects the eyes' ability to focus on close objects. Participants will try the lenses in a random order to determine which offers better comfort and vision. Those who have used soft contact lenses for at least three months and require reading glasses may be suitable for this study. As an unphased trial, it provides a unique opportunity to explore personal comfort and vision preferences with innovative contact lenses.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications.
What prior data suggests that these multifocal contact lenses are safe for presbyopia?
Research has shown that both Clariti® 1 Day Multifocal and Proclear® 1 Day Multifocal contact lenses are generally safe. The FDA has approved Clariti® lenses for daily wear, designed to offer comfort and clear vision for those experiencing age-related difficulty with near vision. Studies on similar lenses indicate a low risk, with few reports of serious side effects.
Similarly, the FDA has approved Proclear® lenses, which are known for alleviating dry eyes while providing clear vision at various distances. Users of Proclear® lenses rarely report severe side effects.
Overall, both types of lenses are well-tolerated, and existing studies suggest they are safe for daily use.12345Why are researchers excited about this trial?
Researchers are excited about these multifocal contact lenses because they offer a potentially superior solution for presbyopia, a common age-related vision problem. Unlike traditional reading glasses or single-vision contact lenses, these lenses are designed to provide clear vision at multiple distances, reducing the need to switch between different pairs of glasses. The unique feature here is the innovative design of the lenses, which allows for a seamless transition between near and far vision. Additionally, the lenses are made from omafilcon A, known for its high moisture retention, which could enhance comfort for all-day wear. This combination of advanced design and material could make these lenses a game-changer for people struggling with presbyopia.
What evidence suggests that this trial's treatments could be effective for presbyopia?
This trial will compare different multifocal contact lenses for presbyopia. Research has shown that Clariti® 1 Day Multifocal 3 Add lenses are comfortable and effective for individuals with presbyopia, a condition where focusing on close objects becomes difficult. In a study with 58 patients at four U.S. clinical sites, these lenses met or exceeded comfort needs. Made from silicone hydrogel, they allow more oxygen to reach the eyes, maintaining comfort and health. The lenses come in various designs to suit different vision needs, with options for low, medium, and high power. Proclear® 1 Day Multifocal lenses are also recognized for their comfort and effectiveness in managing presbyopia. Both types of lenses aim to provide clear vision and comfort, making them suitable choices for those with presbyopia. Participants in this trial will wear different types of study contact lenses, including these options, in a randomized order to assess their effectiveness and comfort.678910
