Stellest Clinical Research
Understanding Stellest Clinical Research
Researchers designed the Stellest clinical trials to determine whether specially engineered spectacle lenses could reduce the speed at which myopia worsens in children. Myopia progression can lead to higher prescriptions over time and increase the risk of vision-threatening complications later in life. The studies aimed to measure how effectively these lenses could slow both the refractive error changes and the physical lengthening of the eyeball that drives myopia.
Investigators wanted solid data showing whether wearing Stellest glasses every day would make a meaningful difference compared to wearing standard single-vision lenses. They also tracked safety, comfort, and whether children could tolerate wearing the lenses throughout their daily activities.
Stellest lenses feature a central zone that provides clear distance correction, surrounded by hundreds of small lenslets arranged in a honeycomb pattern. These lenslets are intended to create a myopic defocus signal while maintaining central distance clarity, which research suggests may slow the elongation of the eye. Standard lenses focus light directly on the retina without this additional optical signal.
The design aims to address the concept of myopic defocus signaling, which evidence suggests plays a role in eye growth. By managing how light reaches different parts of the retina, the lenses attempt to reduce the stimulus for the eye to continue lengthening. The exact biological mechanism is still being studied, and scientists continue to refine the understanding of how optical signals influence axial elongation.
Progressive myopia refers to nearsightedness that continues to worsen over months and years, especially during childhood and adolescence. Clinical studies define progression by tracking increases in the prescription strength and changes in axial length, the measurement from the front to the back of the eye. Even a small yearly increase can add up significantly by the time a child reaches adulthood.
- Higher levels of myopia raise the risk of retinal detachment
- Severe myopia increases the likelihood of glaucoma and cataracts
- Longer eyes have thinner retinal tissue that is more vulnerable to damage
- Slowing progression early may reduce these long-term risks
Before any myopia control intervention can be recommended confidently, we need high-quality evidence showing it works and is safe for growing eyes. Rigorous trials include control groups, standardized measurement methods, and enough participants followed long enough to detect real differences. Without controlled studies, it would be impossible to separate the effect of the lenses from natural variations in how different children's eyes develop.
Eye care professionals rely on peer-reviewed research to guide treatment recommendations. The Stellest trials were designed to meet these standards and provide transparent data on effectiveness and safety.
How the Clinical Trials Were Designed and Conducted
The primary Stellest research included randomized controlled trials, which are considered the gold standard for evaluating medical interventions. Participants were randomly assigned to wear either Stellest lenses or standard single-vision spectacles, ensuring that differences in outcomes could be attributed to the lens design rather than other factors. The studies also included observational phases to gather real-world data on usage and acceptance.
Researchers collected data at multiple sites to ensure findings were not limited to one geographic area or population. This multi-center approach strengthens the reliability of the results.
The published clinical trials used specific inclusion and exclusion criteria to create a well-defined study population. Most studies included children between six and twelve years old with low to moderate myopia. Common inclusion criteria in published trials often limited enrollment based on factors that might affect measurement reliability or treatment response.
- Documented myopia progression over a defined period before enrollment
- Baseline myopia typically ranging from low to moderate levels
- Limits on the degree of astigmatism and anisometropia allowed
- Otherwise healthy ocular findings with no prior eye surgery or disease
- Willingness and ability to wear spectacles full-time with parental consent
In real-world clinical practice, we may consider Stellest for children outside these specific study criteria, though expectations and monitoring may be adjusted based on individual factors.
Researchers measured two main outcomes to assess myopia progression. They tracked changes in the eye's optical power, typically reported as spherical equivalent refraction in diopters, and axial length, the distance from the cornea to the retina measured in millimeters. Both measurements were taken at baseline and at regular intervals throughout the study.
- Cycloplegic refraction is the standard for primary refractive outcomes in pediatric myopia trials to control for accommodation
- Spherical equivalent refraction serves as a common endpoint for comparing progression
- Axial length is measured most commonly with optical biometry using light-based methods, though some settings may use ultrasound
- Consistency of device and measurement protocol across visits is important for reliable tracking
- Repeated measurements and averaging help improve accuracy and reduce variability
Using standardized protocols and well-calibrated equipment helps ensure accuracy and allows comparison across different study sites.
The main Stellest trials followed children for periods ranging from one to three years, with some ongoing studies extending beyond that timeframe. Longer follow-up periods provide more information about sustained effectiveness and whether the treatment benefit continues or diminishes over time. Participants attended regular study visits every six months or annually, depending on the protocol.
Extended observation helps determine whether myopia progression resumes if lens wear is stopped or reduced. It also reveals whether any side effects emerge only after prolonged use.
Clinical Research Results and Effectiveness Data
Published Stellest trial data showed an average reduction in myopia progression of up to approximately 60 to 67 percent compared to children wearing standard single-vision lenses over two years in the specific trial populations studied. This means that children in the Stellest group experienced significantly slower increases in their prescriptions when measured as spherical equivalent refraction change under standardized conditions. The percentage reduction varied depending on how compliance and wear time were measured.
Individual outcomes vary based on factors including baseline age, baseline progression rate, and daily wear time. The magnitude of the effect observed in these trials suggests that Stellest lenses can make a clinically meaningful difference for many children, though results align with the range seen in other optical myopia control strategies studied in recent years.
Axial length elongation was also significantly slower in the Stellest group in the published trials. Over two years, children wearing Stellest lenses had an average axial length increase that was up to about 60 percent less than the control group, measured in millimeters of axial elongation. Since axial elongation directly correlates with myopia progression and long-term eye health risks, slowing this growth is a primary goal of myopia management.
- Shorter eyes have thicker, healthier retinal tissue
- Reducing elongation may lower the cumulative risk of complications decades later
- Even modest slowing can compound into substantial benefits over years of childhood growth
- Individual response varies based on baseline characteristics and wear compliance
Children in the control group wore standard single-vision spectacles that corrected their myopia but provided no myopia control effect. The difference between the two groups became apparent within the first year and continued to widen over the study period. By the end of two years, the gap in both refractive error and axial length was statistically significant and clinically relevant.
Standard lenses remain an appropriate choice for vision correction, but they do not address the underlying progression of myopia. The comparison demonstrated that adding the lenslet design provided additional benefit beyond simply correcting blurry distance vision.
Subgroup analyses revealed that children who wore the lenses for at least twelve hours per day tended to show better myopia control outcomes. Younger children and those with faster baseline progression also appeared to benefit more, though results varied individually. Compliance with full-time wear was a key factor in achieving the treatment effect.
Not every child experienced the same degree of slowing, reflecting natural biological variation. We use this information to set realistic expectations and monitor each child's response over time.
Safety, Comfort, and Compliance Findings
The Stellest trials found very few serious adverse events, and no serious events were attributed to the lenses in the published studies to date. Some children initially noticed peripheral blur or slight distortions in their side vision due to the lenslet design, but these sensations typically diminished within days to weeks. No participants experienced vision-threatening complications linked to the spectacle lenses themselves in the trial populations.
- Mild awareness of peripheral lenslet zones or transient ghosting in peripheral gaze during initial adaptation
- Occasional glare or halos in certain lighting conditions until adaptation is complete
- Mild transient asthenopia or eye strain that usually resolves quickly
- Proper frame fit and centration are important for optimal visual comfort and treatment effect
- Overall safety profile was comparable to standard spectacles with no cases of corneal damage or infection linked to spectacle wear
Researchers tested visual acuity and contrast sensitivity to ensure that the lenslets did not compromise clear central vision. Study participants maintained excellent distance and near visual acuity with Stellest lenses, performing similarly to children in standard lenses on vision tests. The central optical zone provided the necessary correction without degradation in sharpness.
Children reported that they could comfortably perform schoolwork, sports, and screen-based activities. The design aims to balance effective myopia control with real-world visual function.
Most children adapted to Stellest lenses within one to two weeks of starting wear. During this period, they might notice slight differences in peripheral vision or need time to get used to the lens weight and feel. We typically schedule a follow-up visit shortly after dispensing to address any concerns and confirm proper fit and adaptation.
Younger children and those who have never worn glasses before may take a little longer to adjust. Encouragement and consistent wear help speed the adaptation process.
The Stellest trials reported relatively low dropout rates, indicating that most children and families were willing to continue with the treatment protocol. Common reasons for discontinuation included moving away from the study area, difficulty attending follow-up visits, or personal preference to try a different myopia control method. Very few children stopped because of intolerable side effects or discomfort.
- High retention rates suggest good acceptance among participants
- Families valued the potential long-term benefits despite minor initial challenges
- Researchers used intention-to-treat analysis to account for dropouts
Applying Research Findings to Your Child's Care
We compare your child's age, prescription, and eye health to the inclusion criteria used in the Stellest trials. If your child falls within the studied range and shows documented myopia progression, the research data may apply well to their situation. Children outside the studied age or prescription range might still benefit, but we have less direct evidence to guide expectations.
We also consider your child's lifestyle, willingness to wear glasses full-time, and any other eye conditions. A thorough evaluation helps us decide whether Stellest is a good fit for your family.
Stellest is one of several myopia control strategies supported by clinical research. We discuss all appropriate options with families to help you make an informed choice based on your child's needs, preferences, and individual circumstances.
- Low-dose atropine eye drops slow progression in many children but may cause light sensitivity and near blur, and typically require compounding or off-label use with ongoing monitoring
- Orthokeratology uses overnight rigid contact lenses to reshape the cornea, offering daytime freedom from correction but requiring strict hygiene and carrying contact lens-related infection risk
- Multifocal soft contact lenses provide myopic defocus during daytime wear, with effectiveness similar to other optical methods, but require maturity for safe contact lens handling
- Increased outdoor time is one of the most consistent evidence-supported preventive measures, and we recommend at least 90 to 120 minutes of outdoor activity daily when feasible
- Near work habits such as taking regular breaks, maintaining appropriate working distance, and limiting prolonged close tasks may also support eye health
If we recommend Stellest lenses, your child will need to wear them during all waking hours to match the protocol that produced the clinical trial results. You should expect an initial adjustment period during which your child may comment on peripheral visual sensations. We provide guidance on encouraging consistent wear and answering questions that arise.
- Lenses should be worn for at least twelve hours daily
- Regular cleaning and care are the same as for standard spectacles
- Your child can participate in most activities while wearing the lenses
- We monitor response at scheduled follow-up visits
- Treatment typically continues for several years during active eye growth
Clinical trials evaluated participants every six months to track changes in refraction and axial length. We follow a similar schedule, typically seeing your child every six to twelve months while using Stellest lenses. At each visit, we measure the current prescription, assess axial length when available, and check overall eye health.
Many community practices may not have access to optical biometry equipment for axial length measurement. When axial length tracking is not available, we monitor myopia control effectiveness using trends in cycloplegic or standardized refraction, growth curve comparisons, and individualized risk-based follow-up intervals. Frequent monitoring allows us to confirm that myopia is slowing as expected and adjust the plan if progression continues at a rapid pace.
Some initial adaptation symptoms such as mild peripheral awareness or slight visual distortions typically resolve within one to two weeks and are not cause for alarm. However, certain urgent symptoms require immediate attention and should prompt you to contact our office right away.
- New flashes of light in your child's vision
- Sudden increase in the number of floaters
- Appearance of a curtain, veil, or missing area of vision
- Sudden distortion or central blur that does not improve with blinking
- Acute severe eye pain accompanied by redness
We also want to know if your child develops persistent headaches, refuses to wear the glasses, or if follow-up measurements show that myopia is progressing faster than expected despite treatment. If rapid progression continues, we may recommend switching to a different myopia control method or combining approaches.
Frequently Asked Questions
Stellest trials reported progression reductions similar to those found in studies of other optical treatments like orthokeratology and certain multifocal soft contact lenses. Each method has unique benefits and trade-offs, such as daytime versus overnight wear or spectacles versus contacts. We review all available options and help you choose based on your child's age, preferences, and lifestyle.
Not every participant achieved the same degree of myopia slowing, and a small percentage showed minimal or no response. Individual biology, genetics, and compliance all influence outcomes. We cannot predict in advance which children will respond best, so careful monitoring during the first year helps us assess effectiveness for your child specifically.
Research on discontinuation is still emerging, but studies of other myopia control treatments suggest that progression may resume at a rate closer to untreated levels once the optical intervention is removed. For this reason, we typically recommend continuing treatment as long as the eyes are still growing and myopia is still at risk of worsening, usually through the mid to late teenage years.
No treatment can guarantee a specific result for an individual child. The clinical trial data show average effects across large groups, but your child may experience more, less, or potentially no slowing. We use the research as a guide and tailor our recommendations to your child's unique response over time.
Yes, outdoor time remains important even with myopia control lenses. Evidence consistently shows that spending time outdoors, particularly in natural bright light, helps reduce myopia progression risk. We recommend combining Stellest treatment with at least 90 to 120 minutes of outdoor activity daily when possible, as lifestyle measures and optical treatments may provide additive benefit.
We assess treatment effectiveness by tracking your child's prescription changes and, when available, axial length measurements over six to twelve month intervals. We look for slower progression compared to expected rates based on age, baseline myopia, and prior progression history. Because individual growth patterns vary, we typically evaluate trends over at least one year before determining whether to continue, adjust, or change the treatment approach.
