NEW ORLEANS, La. — During the American Academy of Optometry Annual Meeting, CooperVision researchers and partners presented multiple scientific posters with findings that will aid how eye care professionals evaluate and prescribe a range of contact lenses.
“Over recent years, CooperVision has established a major presence on the scientific program at Academy,” said Vice President of Research & Development Francis Erard. “This reflects a deep commitment to extend research and development efforts well beyond commercializing innovative products. Once our contact lenses reach the marketplace, the team’s work continues to help build further confidence and expertise with ECPs and staff, including in selection, fitting, and wearer education,”
The study on “Subjective Vision Experience in Soft Myopia Control Contact Lenses by Age” (Guthrie S, et al.) compared short-term vision of preteens and teens between two lens designs. A total of 26 children aged 8-15 years who had no prior history of contact lens wear or recent myopia control interventions participated in a single-visit, double-masked trial with study lenses — MiSight 1 day and ACUVUE Abiliti 1-Day — randomly fit and worn contralaterally. According to the study, MiSight 1 day was preferred by both groups for better distance vision measured subjectively and objectively, as well as for near visual acuity. Likewise, more preteens and teens chose MiSight 1 day as their overall lens preference after one hour of wear, citing vision as the primary reason. While teens had an equivalent objective vision experience to the preteens for both lenses, they were more likely to subjectively rate that experience lower than preteens. This indicates that teenagers may offer a more critical assessment of their vision, which ECPs should make note of for interactions with patients as they age.
With its growing prevalence in China, MiSight 1 day was also the subject of “Short-Term Clinical Performance and Vision Quality of Dual-Focus Soft Contact Lenses in Myopic Children in Shanghai, China” (Zeng L, et al.). A total of 33 myopic children who were new to soft contact lens wear and had no prior myopia control intervention were fit with MiSight 1 day and then assessed after one week and one month. The lens demonstrated good clinical performance and stable vision quality across both time frames.
Adding an additional study site and more participants to data first shared at the 2023 BCLA Clinical Conference, “Software Guided Orthokeratology Fitting Success” (Luensmann D., et al.) used CooperVision’s Visavy platform to provide recommended parameters for Paragon CRT or CRT Dual Axis Lenses. The experiences of 54 participants across four study sites were analyzed, with topography data, subjective refraction, and white-to-white corneal diameter entered into the software. Only four eyes (<4%) from three subjects required a lens parameter change after the initial Visavy recommendation. This >96% first fit success rate reflects probable time-saving and patient experience benefits of the new decision support technology for orthokeratology practices.
CooperVision is also a sponsor of the Myopia in Practice (MIP) Study presented in New Orleans as part of the American Academy of Optometry Fellows Doing Research special interest group.
The company’s studies shared at Academy were conducted in conjunction with the Centre for Ocular Research & Education (CORE), Waterloo, Ontario, Canada; Ocular Technology Group International (OTGi), London, England; and Eye & ENT Hospital, Fudan University, Shanghai, China.
U.S. Indications for Use: MiSight 1 day (omafilcon A) soft (hydrophilic) contact lenses for daily wear are indicated for the correction of myopic ametropia and for slowing the progression of myopia in children with non-diseased eyes, who at the initiation of treatment are 8-12 years of age and have a refraction of -0.75 to -4.00 diopters (spherical equivalent) with ≤ 0.75 diopters of astigmatism. The lens is to be discarded after each removal.
China Indications for Use: MiSight 1 day is indicated for the correction of myopia for patients with non-diseased phakic eyes, who at the initiation of treatment are 8-12 years of age and have a refraction of -0.75 D to -4.00 D with ≤ 0.75 diopters of astigmatism. It has the dual focal design with alternative multiple rings, which allows part of the light passing through the optical zone to focus in front of the retina, forming myopic defocus with the expectation to slow the change of axial length of the patients. Fitting and evaluation of the product should be in medical institutions by ophthalmologists with an intermediate title or above and with regular monitoring. It must be used in strict accordance with the IFU requirements.
