Benefits of fitting non contact lens wearers with astigmatism with MyDay® 1-day toric contact lenses
If you're aged 18-35 and have astigmatism but have never worn contact lenses before, this study might be for you. Researchers want to understand if contact lenses designed for astigmatism (called 'toric' lenses) are more comfortable and provide better vision than standard contact lenses. You'll wear daily disposable contact lenses for one month and attend two clinic visits. The study aims to compare your comfort and vision satisfaction with these different types of lenses. Potential benefits include trying contact lenses to correct your eyesight. There's a very small risk of eye infection, which is common with any contact lens wear. The study is run by Ocular Technology Group and funded by CooperVision.
At a glance
What is this study about?
This study is designed to help us understand how comfortable new contact lens wearers, especially those with a common eye condition called astigmatism, find different types of contact lenses. Astigmatism means your eye isn't perfectly round, leading to slightly blurry or distorted vision. Historically, some people with astigmatism have found contact lenses less comfortable than those with regular eyesight. This research wants to see if modern daily disposable contact lenses, specifically designed for astigmatism, offer a better experience.
Researchers will compare two types of daily disposable contact lenses: one specifically for astigmatism (called a 'toric' lens) and a more standard lens. They want to find out if there's a difference in how comfortable people feel and how happy they are with their vision when wearing each type. By doing this, they hope to improve the experience for people with astigmatism who are new to contact lenses.
The study is being carried out by Ocular Technology Group - International (OTG-i) in the UK and is sponsored by CooperVision International Limited. It's a 'Phase IV' study, which means it's looking at how a product already on the market works in real-world situations and with different groups of people.
Key takeaways
- Study for new contact lens wearers (18-35) with astigmatism.
- Compares comfort and vision with two types of daily disposable lenses.
- Participation involves two clinic visits and one month of lens wear.
- Potential to try contact lenses for astigmatism correction.
- Small risk of eye infection, common with all contact lens use.
- Study is funded by CooperVision International Limited.
Who may be eligible?
To be considered for this study, you need to be an adult between 18 and 35 years old. A very important rule is that you must have never worn contact lenses before. You also need to have astigmatism, which is a common vision problem.
There are also some specific requirements for your eyesight. Your eyeglass prescription for fuzziness should be between -6.00 and +2.00. For your astigmatism, if you're in the group wearing the standard lenses, it should be between 0.00 and -0.50. If you're in the group testing the astigmatism-specific lenses, it should be between -0.75 and -2.00.
You won't be able to join if you have certain eye problems, like infections, serious dry eyes, or if you've had eye surgery in the past. Also, if you're taking certain medications that could affect contact lens wear, or have other health conditions that might be made worse by wearing lenses, you might not be eligible. The researchers will check all these details to make sure the study is safe for you to take part in.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you between 18 and 35 years old?
- Have you never worn contact lenses before?
- Do you have astigmatism?
- Do you have healthy eyes without current infections or serious dryness?
- Have you not had eye surgery in the past?
- Are you able to attend two clinic visits in the UK?
What does participation involve?
If you decide to join the study, you'll need to attend two appointments at the clinic. At your first visit, you'll be fitted with one of the two types of daily disposable contact lenses – either the standard lens or the one designed for astigmatism. You'll then wear these contact lenses every day for one month, throwing them away after each use. During this month, you'll also fill out some questionnaires about your experience. Your second visit will be after one month of wearing the lenses, where the researchers will check your comfort and how satisfied you are with your vision. The study is expected to run from March 2025 to October 2025.
