What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing eye drops and special glasses or contact lenses to see if they can slow down worsening nearsightedness in children by controlling eye growth and changing how light enters the eye.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, if you are using any form of myopia control or certain contact lenses, you may not be eligible to participate.

Is the combination of atropine and MiSight contact lenses safe for treating near-sightedness?

Research shows that using low-concentration atropine and MiSight contact lenses is generally safe for children with near-sightedness. Studies have monitored children for adverse reactions and found no significant safety concerns over a year of treatment. ^{1 2 3 4 5}

How does the treatment of atropine and MiSight contact lenses for near-sightedness differ from other treatments?

The combination of 0.05% atropine eye drops and MiSight contact lenses is unique because it targets myopia (near-sightedness) progression by using both a pharmacological approach and a specialized contact lens that alters how light focuses on the retina. This dual approach has shown effectiveness in significantly slowing myopia progression in children, which is not typically achieved with standard glasses or contact lenses alone. ^{1 2 6 7 8}

What data supports the effectiveness of the treatment for near-sightedness?

Research shows that using 0.05% atropine eye drops combined with MiSight contact lenses can significantly slow down the progression of near-sightedness in children. In a study, this combination reduced the average myopia progression from -1.45 to -0.41 over one year, indicating its effectiveness in controlling myopia. ^{1 4 6 9 10}

The combination of 0.05% atropine eye drops with MiSight® 1 day contact lenses effectively reduced myopia progression in four children, decreasing their average myopia change from -1.45 D to -0.41 D over one year.

This case series, involving children with an average age of 9.68 years, is the first to demonstrate the efficacy of this combination treatment in controlling moderate myopia progression, with no reported adverse reactions during the study.

In a study involving 97 Danish children aged 6 to 12, low-dose atropine eye drops (0.1% and 0.01%) were found to be safe over a 12-month period, with most reported adverse events being mild.

The treatment showed a modest reduction in myopia progression, with the 0.1% group experiencing 0.24 D less progression in spherical equivalent refraction compared to placebo, although this result was not statistically significant after adjustments.

A retrospective study of 79 patients over ten years found that atropine eyedrops can effectively manage myopia, especially in children with low refractive errors, who are more likely to benefit from the treatment.

Children who responded well to atropine in the first year tended to continue treatment, while those with less favorable results often stopped, indicating the importance of early response in treatment adherence.

Further observations on use of atropine in the treatment of myopia. Brenner, RL.[2013]

In a study involving 438 children aged 4 to 12, low-concentration atropine eye drops (0.05%, 0.025%, and 0.01%) significantly reduced myopia progression compared to placebo over one year, with the 0.05% concentration being the most effective.

All concentrations of atropine were well tolerated and did not negatively impact visual acuity or quality of life, indicating a safe option for managing myopia in children.

Atropine, particularly at a concentration of 0.05%, is effective in slowing the progression of myopia and controlling axial length growth, which can help prevent serious eye conditions.

The treatment is generally safe and well-tolerated, but it requires long-term use, potentially extending into adolescence, to maintain its benefits and manage the rebound effect after stopping treatment.

The study evaluated a combination of cyclopentolate and tropicamide (CTA) for cycloplegia in 33 black children, finding it to provide reliable refractive results similar to atropine, which is the gold standard.

While atropine is more effective, the CTA combination is less disabling and offers a satisfactory alternative for routine use in children, making it a practical option for objective refraction.

A case report highlighted that the use of Lameline suppositories, which contain atropine derivatives, led to prolonged non-reactive dilation of the pupils (mydriasis) and cycloplegia, indicating potential ocular sensitivity in some individuals.

This case emphasizes the importance of recognizing the presence of atropine derivatives in medications and adhering to contraindications, even at low doses, to prevent adverse effects.

The MOSAIC trial is a double-masked, placebo-controlled study involving 250 children aged 6-16 years, investigating the efficacy and safety of 0.01% unpreserved atropine for controlling myopia progression over 24 months.

This study is significant as it is the first randomized clinical trial to assess atropine's effects in a predominantly White population, addressing the limitations of previous studies that primarily included Asian participants.

The study investigated how different drugs, including atropine and gentamicin, are absorbed and released in soft contact lenses with varying hydrophilic properties and thicknesses, using radiometry to measure these kinetics.

Factors such as the chemical structure of the drug, the hydrophilic nature of the contact lenses, and the temperature of the solution significantly influenced the absorption and desorption rates of the drugs in the lenses.

Cyclopentolate demonstrated the least residual accommodation (1.48 D) compared to homatropine (2.32 D) and atropine (1.10 D), indicating it may provide a more effective cycloplegic effect for eye examinations.

The study suggests that cyclopentolate could be recommended as a routine cycloplegic agent in children due to its favorable balance of efficacy and safety, as evidenced by the measured differences in retinoscopy readings among the three agents.
