World’s First Marketed Drug Delivery Lens Approved by the FDA

Johnson & Johnson Vision Care has received U.S. Food and Drug Administration (FDA) approval for their drug-eluting contact lens: ACUVUE® Theravision™ with Ketotifen (etafilcon A drug-eluting contact lens with ketotifen). Each lens contains 19 mcg ketotifen. Ketotifen is a well-established antihistamine. ACUVUE® Theravision™ with Ketotifen is the first in an entirely new category of contact lenses and brings forward a new wearing experience for contact lens wearers with allergic eye itch. According to Phase 3 clinical studies, ACUVUE® Theravision™ with Ketotifen showed a clinically and statistically meaningful reduction in itchy allergy eyes as quickly as 3 minutes after lens insertion and lasting up to 12 hours; however, the lens may be worn for longer than 12 hours for vision correction.

SightGlass Vision™ Diffusion Optics Technology™ Demonstrates Significant Reduction in Myopia Progression After Two Years in Clinical Trial

CooperVision’s SightGlass Vision Business has revealed two-year clinical study data for its Diffusion Optics Technology (DOT), which is specifically designed to slow the progression of myopia in children. After two years, children who wore their DOT-enabled spectacles full time, including not removing them for near vision activities, progressed on average one-half dioptre less than those wearing the control spectacles—a reduction of 59%.

The news was presented during a launch event in the Netherlands, timed with the world’s first commercial launch of the technology. The product will be available from CooperVision to eye care professionals in the Netherlands beginning this month. EssilorLuxottica, which will also introduce the spectacle lenses with Diffusion Optics Technology also participated.

The CYPRESS clinical study enrolled, randomized, and dispensed the lenses to 256 eligible children across 14 clinical trial sites in the United States and Canada. At the time of enrolment, subjects were six to 10 years old having myopia between -0.75 D and -4.50 D. After two years of wear, 85% of children wearing the innovative spectacle lenses showed less than one dioptre of myopia progression.4 Moreover, the study also showed that 41% of the children wearing spectacle lenses with DOT showed no clinically meaningful progression in refractive error after two years versus only 17% in the control group.

The last few decades have seen a steady rise in the prevalence of myopia across the globe, notably under the effect of lifestyle changes. Today affecting 2.6 billion people worldwide, it is estimated that half of the world population, will be myopic by 2050 (Holden et al. Ophthalmology 2016. 123:1036-1042).

Spectacle Lenses Effective in Reducing Myopia Progression

Data presented at the 2020 American Academy of Optometry meeting demonstrate the effectiveness of novel spectacle lenses in slowing the progression of myopia in children. The lenses utilise SightGlass Vision’s Diffusion Optics Technology (DOT). The CYPRESS study (Control of Myopia Using Peripheral Diffusion Lenses: Efficacy and Safety Study) is a prospective, multi-centre, subject- and observer-masked, randomized, controlled clinical trial in 256 children aged 6 to 10 years. The study compared two DOT designs against a control lens. At the time of enrollment, study participants had myopia between -0.75 D and -4.50 D. The results indicate a reduction in myopia progression (cycloplegic spherical equivalent refraction) of up to 74% at 12 months. A reduction in axial length progression of up to 50% was also seen for the same time period.

The study sponsored by SightGlass Vision Inc. has been supervised by Visioncare Research at fourteen investigational sites in Canada and the United States.

CooperVision Presents 6-Year Data on MiSight® Study: Myopia Progression in Children

CooperVision has reported the latest findings from its landmark MiSight® 1 day clinical study, providing new insights about myopia management and the proven efficacy of the specially designed contact lens.* Among several interesting findings are that the myopia of nearly one in four children originally fit with MiSight® 1 day remain stable after six years. CooperVision MiSight® 1 day is the first and only soft contact lens the U.S. Food and Drug Administration has approved for slowing the progression of myopia in children, who at initiation of treatment are 8-12 years of age.

Paul Chamberlain, CooperVision's Director of Research Programs, presented additional details during a paper presentation at the 2020 American Academy of Optometry's virtual meeting. "Evaluating children who were prescribed MiSight® 1 day at the study's initiation, 23% of eyes after year six displayed a total refractive change of less than -0.25D (spherical equivalent), which could be considered clinically stable," said Chamberlain. The newest findings also suggest that while intervention at an early age is optimal with MiSight®, commencing treatment at an older age could similarly slow the rate of myopia progression. The original control group was refit into the dual-focus lens in year four. Comparing this population to the children fit with MiSight® 1 day at initiation, there have been similar rates of myopia progression and axial length growth in the subsequent three years of assessment.

Six-year results continue to demonstrate excellent safety profile, wearing time, and visual acuity for children in daily disposable contact lenses over 653 wearing years. No other prospective randomized controlled study has offered conclusive data for such a high degree of continued efficacy in myopia management using a soft contact lens over a similar time span.

FDA Approves First Contact Lens for Myopia Control

CooperVision has received U.S. Food and Drug Administration (FDA) approval for the innovative MiSight® 1 day contact lens. This daily wear, single use soft contact lens is the first FDA-approved product clinically proven to slow the progression of myopia (short-sightedness) when prescribed for children 8-12 years old. Myopia affects 42% of U.S. children aged 5-19 according to a study published in Clinical Ophthalmology in August 2018. Myopic progression has been linked to sight-threatening conditions later in life such as cataracts, retinal detachment, glaucoma and myopic maculopathy. MiSight’s effectiveness has been supported by a prospective, multi-centre, double-masked, randomized multi-year study that enrolled 144 myopic children aged 8-12 years. Three-year peer-reviewed results published in Optometry and Vision Sciences in August 2019* indicated that use of MiSight 1 day was shown to slow myopia progression: 59% as measured by mean cycloplegic spherical equivalent (SE) and 52% as measured by mean axial elongation of the eye.

The study sponsored by CooperVision has been supervised by Visioncare Research at four investigational sites: Aston University, Birmingham UK; National University Hospital, Singapore; University of Waterloo, Canada; University of Minho, Portugal.

The Need for Toric-Multifocal Contact Lenses

Data presented at the recent American Academy of Optometry meeting in San Antonio suggest that a surprisingly high proportion of the over-40’s could benefit from toric multifocal contact lenses.  Visioncare Research undertook a chart review of 1001 presbyopic and pre-presbyopic patients (age: 40 to 70 years) among twenty optical practices in the US.  Most of the presbyopic patients (57%, 546/950) had significant astigmatism (≥0.75DC) in at least one eye; 33% had significant astigmatism in both eyes.  Even using the higher astigmatism threshold of 1.00DC, 39% (370/950) of presbyopes showed this level of astigmatism in at least one eye; 19% in both eyes.

The study was funded by Johnson & Johnson Vision Inc.

CooperVision Releases 4-Year Data on MiSight® Study: Myopia Progression in Children

An ongoing study of myopia control has shown significant benefits in children using dual-focus daily disposable soft contact lenses.  After 3 years, myopia progression slowed in children wearing the MiSight® contact lens: 59% as measured by mean cycloplegic spherical equivalent (SE) and 52% by mean axial elongation of the eye when compared to children wearing a single vision contact lens (AAO 2017).  Recently released results show that the treatment continues to work for children who have been using the lens for 3 years and is also effective for children previously wearing single vision contact lenses.  The treatment is continuing to work for children who have been wearing MiSight® contact lenses for the entire study, and their axial length progression in this last year has slowed further. Furthermore, in the study, the myopic control effects were similar for the two groups of children.  According to Paul Chamberlain, Director of Research Programs for CooperVision, “This illustrates the benefits of beginning myopia management as early as possible to maximize the benefit”.

The study sponsored by CooperVision is being supervised by Visioncare Research at four investigational sites: Aston University, Birmingham UK; National University Hospital, Singapore; University of Waterloo, Canada; University of Minho, Portugal.

Preventing Contact Lens Drop-outs

Visioncare Research CEO, Graeme Young, presented at the recent European Society of Contact Lens Ophthalmologists (BCLA) Conference in London.  The lecture, entitled ‘Preventing Contact Lens Drop-outs’, reviewed recent research into factors affecting contact lens success and proposed strategies for avoiding drop-outs.  These include: i) ensuring that new wearers understand that it may be necessary to try several products to find the optimum solution but that a wide range is available, ii) following-up new wearers by phone, text message or email, iii) with existing wearers, watching out for and treating any dryness problems, and iv) with presbyopes, using a holistic approach to ensure that all of their visual needs are catered for.

Comparing Chart Review and Registry Study Designs

Visioncare Research CEO, Graeme Young, presented a research paper at the recent British Contact Lens Association (BCLA) Conference in Liverpool, UK.  The lecture, entitled ‘Contact lens wearer retention rates - Retrospective versus prospective evaluations’, compared the advantages and disadvantages of these two approaches.  A retrospective evaluation is likely biased towards over-estimating dropout rates while a prospective study may be biased towards under-estimating dropouts.  In the studies reported, the new contact lens wearer dropout rates were 26% and 22%, respectively, suggesting a true rate of approx. 24%.  The findings will be published in Eye & Contact Lens.*

The studies were funded by Johnson & Johnson Vision Care Companies.

Study Points to Methods of Reducing Contact Lens Dropout

A study published in the journal Contact Lens and Anterior Eye* evaluated the retention rate for patients fitted with contact lenses for the first time based on a retrospective chart review.  Approximately one in four gave up contact lenses in the first year, many doing so in the first two months.   In contrast with previous studies, the most common reason cited for discontinuation was visual problems, followed by comfort problems.  This perhaps reflects the growing range of complex lens designs for the correction of astigmatism and presbyopia.  On the positive side, a high proportion of the new lens wearers were in older age groups (31% >45 years) and those in the 45-59 age group were just as likely to be successful as younger patients.

Only a small proportion of those patients discontinuing were offered or tried an alternative lens type.  The findings point towards several strategies for ensuring that new contact lens wearers are given the best possible chance of success: i) ensuring new wearers realise that a wide range of contact lens designs is available, ii) encouraging patients to return promptly if they encounter problems, iii) following-up new contact lens wearers by phone or email to check they are happy, and iv) optimising vision and comfort for all wearers.

The study was funded by Johnson & Johnson Vision Care Companies.

Visioncare Research at American Academy of Optometry Meeting in Anaheim

Visioncare Research representatives will be co-authoring a range of posters at the forthcoming AAO meeting in Anaheim, California.  New research will explore the effect of fitting larger than optimal diameter soft contact lenses.  Extra-large soft lenses might be expected to be less comfortable and cause greater effect on ocular physiology. However, clinical findings suggest that, provided the basic fit is optimal, extra-large lens fittings show similar clinical performance to optimal diameter lenses.

Visioncare Research at British Contact Lens Association (BCLA) Conference in Liverpool

Visioncare Research, presented the interim findings of a project evaluating contact lens success at the recent BCLA international conference in Liverpool U.K.  A multi-centre study conducted at 26 practices around the U.K. is throwing light on reasons why some patients struggle with contact lens wear.  Nearly 10% of new wearers give up contact lenses in the first month.  Vision appears to have overtaken discomfort as the prime reason for discontinuing contact lens wear.  This change may be linked to the advent of many new contact lens materials in recent years, specifically designed to give better, longer lasting comfort.  The authors conclude that better communication is needed between new contact lens wearers and their eyecare providers, as many of the visual problems experienced by patients can be overcome by modifying lenses or trying alternative designs.

The study was sponsored by Johnson & Johnson Vision Care, part of Johnson & Johnson Medical Ltd.

New Partnership to Improve Ophthalmic Instruments

Visioncare Research is working on a Technology Strategy Board funded project worth almost £150,000 with academics from Aston University’s School of Life and Health Sciences and Optimec Ltd, a manufacturer of contact lens measuring instruments.

The project, led by Optimec Ltd and with academic expertise from Prof. James Wolffsohn and Dr Thomas Drew, aims to significantly improve ophthalmic imaging instrumentation by developing further the use of wavefront sensing. Improved imaging will enable validation of medical devices such as contact lenses and intraocular lenses during manufacture to become more accurate.  The imaging device will also be used during ophthalmic surgery to examine how the medical device impacts on the surrounding tissue of the eye and its impact on light focus, in combination with the refractive ocular tissues, to give good vision. It will also allow changes over time following implantation or insertion to be monitored.  Current instruments cannot deliver this range of information and most verification that a product meets its design parameters is performed manually, increasing costs and the potential for error.

This project will develop a prototype instrument to validate medical devices during the production process for dimensions and optical quality, ensuring safe and optimal surgical implantation or placement on the ocular surface.  If successful, this should help Optimec increase their instrumentation sales, secure more clinical studies for Visioncare and enhance the profile of industry-based research at Aston.

Professor James Wolffsohn said of the project: “We are delighted to have been awarded this project.  Transferring the knowledge available here at Aston should provide Optimec and Visioncare Research with cutting edge methods and provide an ambitious and significant project.”

Complications with Unregulated Contact Lens Supply

A review from Visioncare Research, just published in the journal Eye & Contact Lens, suggests that the unregulated supply of contact lenses puts patients at greater risk.  The supply of contact lenses through unregulated internet sites, novelty shops and other unconventional suppliers is more likely to result in the use of inappropriate lenses, poor hygiene, and delayed treatment of any consequent complications.  The review summarises 70 individual cases from the literature of complications arising from the use of such lenses; in more than a half of cases, patients suffered permanent damage.

Not All Contact Lens Dryness Symptoms Relate to Dry Eye

A recent multi-centre clinical investigation sponsored by Alcon Research has thrown light on some of the underlying causes of dryness symptoms in soft contact lens wearers.  The study, supervised by Visioncare Research Ltd, involved 226 soft lens wearers with significant symptoms of lens-related dryness.  Each participant underwent a detailed examination comprising a battery of dry eye tests to assess the ocular surface and the tear film with and without contact lenses.  The most common (30%) cause of dryness was found to be insufficient lacrimal secretions (i.e. the watery part of tears), followed by unstable lens wetting (25%).  However, nearly a quarter (23%) of participants showed no actual signs of dry eye.  The research team concluded that factors other than dry eye were responsible for symptoms in many contact lens wearers; they suggest that factors such as lens fit and disinfection solution might be more important than previously thought.

These findings were presented at the American Academy of Optometry meeting in November 2010 and are awaiting publication in a scientific journal.
