Subjects viewed spots on the wall created by a laser pointer at 20, 30, and 40 degrees nasal and temporal and at physical targets at 20 and 30 degrees superior and inferior. Overall, the BLINK study will provide a much more thorough investigation of the optical ramifications of the soft multifocal contact lens on myopia progression than any study reported to date. Provide the most comprehensive and unbiased consumer guide with contact lens, vision correction and related eye care information. Only three subjects (0.7%) were ineligible because they could not achieve +0.1 logMAR binocular visual acuity while wearing +2.50-D add power contact lenses. The BLINK study will be the largest and longest contact lens myopia control study performed to date (Table 1). They provide a remarkable balance of comfort, breathability and excellent visual clarity. UV-B Blocking covers the 280nm to 315nm spectrum. In order to be classified into one of the groups, the UV blocking capabilities must meet the following requirements: IMPORTANT NOTE: UV-absorbing contact lenses are not substitutes for protective UV-absorbing eye-wear, such as UV-absorbing goggles or sunglasses, as they do not completely cover the eye and surrounding area. To determine the weighted average percent slowing of eye growth for each study, we subtracted the mean eye growth of the experimental group from the control group and divided by the eye growth of the control group. The primary outcome of the BLINK study is the 3-year change in spherical equivalent, cycloplegic autorefraction. The BLINK study uses Biofinity Multifocal D contact lenses (Comfilcon A; CooperVision, Victor, NY), so practitioners will be able to apply the results of the BLINK study immediately. Peripheral Refractive Errors in Myopic, Emmetropic, and Hyperopic Young Subjects. Newell DJ. Walline JJ, Jones LA, Sinnott L, et al. If you experience any symptoms such as redness, watering, discharge, bluriness, pain or discomfort, stop using your eyecare products immediately and check with your eye doctor. Comparing Biofinity Toric Multifocal to Ultra Multifocal for Specifications i. Lam CS, Tang WC, Tse DY, et al. The BLINK study will randomly assign subjects to single vision, +1.50-D add, or +2.50-D add to determine whether higher add powers provide better myopia control. Study record managers: refer to the Data Element Definitions if submitting registration or results information. The objective of the study was to compare the handling and performance of Biofinity Toric Multifocal to Ultra Multifocal for Astigmatism. Multifocal, bifocal and presbyopic contact lenses have an additional prescription parameter named 'ADD power'. CooperVision's Balanced Progressive Technology delivers exceptional vision at all distances, while a streamlined fitting approach means fitting presbyopes just got easier. The protocols were approved by The Ohio State University Bio-medical Institutional Review Board and the University of Houston Committee for the Protection of Human Subjects. AIR OPTIX plus HydraGlyde contacts use Alcon's proprietary SmartShield Technology and HydraGlyde Moisture Matrix technology to ensure a comfortable contact lens-wearing experience. Salmivalli C, Isaacs J. Biofinity multifocal Contact Lenses | CooperVision The primary reasons for ineligibility were myopia out of range (n = 58), astigmatism too high (n = 44), monocular best-corrected visual acuity worse than +0.1 logMAR with manifest refraction (Snellen 20/25, n = 19), could not agree to participate for 3 years (n = 16), strabismus (n = 10), unaccepted contact lens fit (n = 3), anisometropia (n = 1), and previous bifocal spectacle wear for more than 1 month (n = 1). The BLINK study subjects are similar to patients who would routinely be eligible for myopia control in practice, so the results will provide clinical information about soft bifocal contact lens myopia control as well as information about the mechanism of the treatment effect, if one occurs. Cessation Age of Childhood Myopia Progression. In addition, this will be the first longitudinal myopia control study with control subjects to determine whether higher add powers provide better myopia control, to examine peripheral refractive error in both the horizontal and vertical meridians, and to measure peripheral eye growth. A varying block size was used, and the allocations were made with equal probability. . Comfort Both AIR OPTIX plus HydraGlyde and Biofinity deliver long-lasting comfort, but how they go about that is vastly different. Both lenses provide excellent vision - at reading, far and intermediate distance. Our comparison table below details the differences between these two multifocal contact lenses. AquaClear contact lenses are identical to Biofinity contact lenses. Validity of the Convergence Insufficiency Symptom Survey: A Confirmatory Study. Myopia Control with Orthokeratology Contact Lenses in Spain: refractive and biometric changes. Longer siloxane molecules attract and bond to surrounding water molecules, continuously wetting and lubricating the lens material. and transmitted securely. By proceeding, you are declaring you are a registered eye care professional. Comfilcon A 52%, H2O 48% (SiH48) Packaging: 1 box of 6 lenses. What are the advantages of contact lenses? The benefits of peripheral myopic defocus may be exhibited by all treatment groups, especially the multifocal groups, so we will examine peripheral myopic defocus across the entire sample. Vision Specific Quality of Life of Pediatric Contact Lens Wearers. Charm J, Cho P. High Myopia-partial Reduction Ortho-k: A 2-year Randomized Study. Indicators of gaze direction and location will be included along with treatment group and time in a repeated-measures analysis of covariance model.

Peripheral Pptics with Bifocal Soft and Corneal Reshaping Contact Lenses. Total person-years = (65 2) + (63 2) = 256 person-years. Known from auto-darkening eyeglasses, this new feature will be available for the first time in 2019 as it will mark the date for the introduction of the world's first contact lens that adapts to changing light conditions. If the subject read three or more letters correctlyonthe bottom line, then the subject moved to 6 m and started the process again. Please remove one or more studies before adding more. Before Near targets were placed at 33 cm 2.06 M size letters (20/125 Snellen equivalent). Biofinity multifocal. Smith EL, 3rd, Kee CS, Ramamirtham R, et al. Find the best prices from the most popular retailers. For vertical readings, the forehead rest was used, and the subject's chin was placed on the chinrest. Peripheral Vision can Influence Eye Growth and Refractive Development in Infant Monkeys. Santodomingo-Rubido J, Villa-Collar C, Gilmartin B, et al. Repeatability and Comparison of Peripheral Eye Lengths with Two Instruments. Fujikado T, Ninomiya S, Kobayashi T, et al. Treatment assignments were concealed until the eligibility form was verified, at which time REDCap produced the next allocation in the sequence. Masked examiners were not allowed in the clinical area, other than to perform their masked examination duties. Between October 17, 2014, and June 20, 2016, 443 subjects attended baseline visits to determine final eligibility, and 294 subjects were enrolled. With Balanced Progressive Technology, CooperVision Biofinity multifocal contacts allow you to see near and far objects, along with everything in-betweenall with the clarity and comfort you deserve. Bailey-Lovie logMAR high-contrast charts 4 and 5 and low-contrast visual acuity chart 6 were used at a test distance of 4 m. Subjects read the first letter of every line until one was incorrectly read. Data Coordinating Center: Loraine T. Sinnott (biostatistician), Pamela Wessel (project coordinator), Jihuyn Lee (research programmer, 2015 to present). Shammas HJ, Ortiz S, Shammas MC, et al. The visual acuity had to be 20/25 or better with spectacle correction to reduce the likelihood of enrolling an amblyopic child and 20/25 or better with a +2.50-D add to reduce the likelihood of poor subjective vision with the highest add power used in the study. Walline JJ, Jones LA, Sinnott L, et al. During the 6-, 18-, and 30-month visits, the contact lens fit and compliance were assessed, and surveys were administered. If your vision is starting to change, if you want a contact lens with outstanding visual performance and premium comfort, you can rely on CooperVision Biofinity multifocal contact lenses. Primates with form deprivation1 or hyperopic blur2 imposed outside the macula experience excessive axial elongation and myopia progression. Walline JJ, Gaume A, Jones LA, et al. Soft multifocal contact lenses slow axial elongation of the eye, but no myopia control studies have examined the peripheral growth of the eye to determine the extent of spatial integration of optical cues to globally slow eye growth or whether the eye experiences only local changes in eye growth that result in slower myopia progression. The proportion of female participants is the same as the median percentage (60%) of the other soft multifocal contact lens studies (range, 47% to 73%), and the average age is younger than all but one of the soft multifocal contact lens myopia control studies (Table 5). If subjects or parents believed they were unmasked, we never confirmed whether they were correct or not, so they were never certain of whether they were unmasked. Using these repeated measurements gives us the greatest power to detect differences between the treatment groups by maximizing the degrees of freedom associated with the estimated mean square error, giving the best estimate of variability. Ticak A, Walline JJ. Inspired by the way the eye's tear film works, this wetting agent keeps the contacts wet and smooth for all-day comfort. Observations were made with cobalt blue and Wratten no. Rah MJ, Walline JJ, Jones-Jordan LA, et al. The range of spherical equivalent myopia in the other studies was from 0.75 to 7.00 D, but the average in almost every case was in the 2.00 D range, as it was in the BLINK study. This article describes the subjects' baseline characteristics and study methods. Shop Now Shop Now Which is better Proclear or Biofinity? 2) Biofinity toric contact lenses are designed to give you both comfort and vision stability. It is equal to the oxygen permeability divided by the thickness of the measured sample under specific conditions. Prices might further vary based on buying multiples or after applying coupons or rebates. Mutti DO, Jones LA, Moeschberger ML, et al. Myopia progression will be measured by the change in cycloplegic spherical equivalent refractive error from baseline to 3 years. government site. Measurement of pupil diameter of the right eye was performed with the NeurOptics VIP-200 Pupillometer (NeurOptics, Inc., Irvine, CA). Relative Peripheral Hyperopia does not Predict Development and Progression of Myopia in Children. Relative Peripheral Hyperopic Defocus Alters Central Refractive Development in Infant Monkeys. Fitting your presbyopic patients just got easier. The subject then read all five letters of the line, beginning two lines above the first letter missed. Creates an optimised balance of high oxygen permeability, good water content and optimum modulus to provide increased breathability and moisture in a soft, flexible lens. Subjects and parents were also masked, and they were told not to discuss their contact lens wear, vision, or care with the masked examiner. In order to view some areas of this website you will need to register and login. Mutti DO, Sinnott LT, Mitchell GL, et al. Finally, we divided the sum of the weighted percent slowing for each study by the sum of the total person-years for each study to determine the weighted average percent slowing. The New Biofinity Multifocal Fitting Guide - Eyedolatry Comparison of Two Multifocal Contact Lenses - Full Text View CooperVision is offering a D lens and a N lens version, D for the dominant eye, N for the non-dominant eye which promises to simplify the fitting process for doctors. Center near or concentric ring multifocal contact lenses may also slow myopia progression, but they were not used in the BLINK study. Some subjects were ineligible for more than one reason. Lntention-to-treat Analysis: Implications for Quantitative and Qualitative Research. Measurements were performed while the right eye was corrected with a trial lens equal to the spherical equivalent of the manifest refraction and the left eye was occluded. The new Pediatric Refractive Error Profile 2 elicited vision-specific quality-of-life scores sensitive enough to measure differences between children affected only by refractive error who wore different vision correction devices.55,56 The Pediatric Refractive Error Profile 2 consisted of 56 items, half positively worded and half negatively worded in seven scales: overall, vision, symptoms, appearance, activities, handling, and peer perception. Sankaridurg P, Holden B, Smith E, 3rd, et al. Myopia Control with Bifocal Contact Lenses: A Randomized Clinical Trial. Bold font indicates masked measures. The site is secure. A new contact lens power was provided if the overrefraction exhibited myopia progression of more than 0.50 D, or if the examiner deemed it to be necessary. The minimal difference in central refractive error change detected in a previous study was 0.13 D over 1 year.27 If this difference was expanded linearly for 3 years, the minimal meaningful difference would be 0.39 D. The SD of the change was set at 0.85, based on the most conservative SD in the change in relative peripheral refraction seen across peripheral measures in the STAMP (Study of Theories about Myopia Progression) study.41 Using this information, the sample size required to detect this magnitude of difference in the change in ocular shape between treatment groups was 89 subjects per group, for a total sample size of 267 subjects. Horner DG, Soni PS, Salmon TO, et al. Contact lens movement was graded as extremely inadequate (no movement), slightly inadequate (<0.2 mm), optimum (0.2 to 0.4 mm), slightly excessive (0.4 to 1.0 mm), and extremely excessive (>1.0 mm). People that reach their 40s and have difficulties reading small print can keep everything in focus - close up, far away, and in-between. Previous single-vision soft contact lens wear was permitted because single-vision soft contact lenses do not alter the progression of myopia.38,39 Subjects also needed to be free of systemic issues that may have affected myopia or myopia progression, could not be chronically using oral or ophthalmic steroids, and had to be willing to participate in the study for 3 years to reduce the likelihood of dropout. The comparability of the treatment groups at baseline was evaluated by the 2 or Fisher exact test for categorical variables or an analysis of variance for continuous variables to verify a reasonable distribution of covariates as a result of randomization. At least five readings in which neither the sphere nor cylinder differed from the median by more than 1.00 D were recorded. Your eye is getting multiple images at the same time, and the brain interprets them. The pink reticule was centered in the entrance pupil (not in the white keratometry circle reflecting off of the cornea), and the iris was focused. The sample was not limited to a younger age group in order to maximize generalizability of the results, which provides eye care practitioners with evidence for or against myopia control in the wide range of ages they treat. ACUVUE OASYS for ASTIGMATISM vs Biofinity Toric - Optix-now No study is free of limitations. They never examined subjects while they were wearing contact lenses, and all contact lens cases and packages were hidden during the masked portion of the examinations. In summary, the BLINK study provides the most comprehensive array of measures to determine whether soft multifocal contact lenses slow myopia progression, and if proven to be effective, this study will provide information on how soft multifocal contact lenses can be optimized for myopia control. Peripheral myopic defocus is quantified (right eye only) by peripheral refractive error in the nasal and temporal locations in gaze directions at 20, 30, and 40 degrees and in the superior and inferior locations at 20 and 30 degrees while the subject is wearing the treatment contact lens. Santodomingo-Rubido J, Villa-Collar C, Gilmartin B, et al. Biofinity multifocal is everything you'd expect in a contact lens. Your wearing schedule should be determined by your Eye Care Professional. The randomization schedule was created by the director of the coordinating center using a random-number generator in Excel and imported into REDCap. AIR OPTIX plus HydraGlyde for ASTIGMATISM, Bausch + Lomb ULTRA Multifocal for Astigmatism. Comfilcon A Specsavers . A Randomized Trial of the Effects of Rigid Contact Lenses on Myopia Progression. . The result is a lens with very high oxygen transmission AND a high water content that minimizes deposits. For horizontal readings, the forehead rest was removed, the subject's chin was placed on the chinrest, and the subject turned the head (as opposed to the eyes) to the target while maintaining primary gaze. Brief Summary: The purpose of this study is to compare two multifocal contact lenses in presbyopic wearers. Effect of Low-addition Soft Contact Lenses with Decentered Optical Design on Myopia Progression in Children: A Pilot Study. Kakita T, Hiraoka T, Oshika T. Influence of Overnight Orthokeratology on Axial Elongation in Childhood Myopia. Other contact lenses were used as deemed clinically necessary because all subjects who were randomly assigned to a treatment group were analyzed according to the intention-to-treat principle.45 Parameters of the primary and secondary contact lenses are listed in Table 4. Careers, Unable to load your collection due to an error. There are some differences between these lenses and Proclear Multifocal, but the design is very similar. Presbyopic patients who experience discomfort due to dryness when wearing contact lenses and are therefore looking for outstanding 24-hour comfort. The New Biofinity Multifocal Fitting Guide 4:08 PM I like to describe the way this lens works to the patient (briefly) because it can really set expectations to an appropriate place. The minimum age of 7 years was chosen because younger children may be less able to care for contact lenses; the maximum age of 11 years ensures that subjects will be younger than the expected age of cessation of myopia progression at the conclusion of the study.34 The minimum amount of myopia (0.75 diopter [D]) was used because children with less myopia may not be as motivated to wear contact lenses.25 The upper limit (5.00 D) eliminates pathological myopia that may have a different mechanism and protects against refractive error imbalance between the two treatment groups because of extreme outliers. People who are looking for breathable monthly lenses for healthy and extended overnight wear. The letters were presented at optical infinity, then moved to a slightly blurred position to ensure relaxation of residual accommodation.46 The 10 spherocylindrical autorefractions were averaged using the power vector analysis described by Thibos et al.47. Prospective Relations among Victimization, Rejection, Friendlessness, and Children's Self- and Peer-perceptions. Cycloplegia was achieved using one drop of 0.5% proparacaine or tetracaine followed by two drops of 1.0% tropicamide, separated by 5 minutes. If masked examiners became unmasked, they never examined that subject again. All study personnel were unmasked except the masked examiners, who performed cycloplegic autorefraction, axial length, peripheral refractive error without contact lenses, and peripheral eye length. 1. The higher the oxygen transmissibility the easier it is for oxygen to flow through to your eye. The BLINK study is a National Eye Institute-sponsored, double-masked, randomized clinical trial to investigate the effects of soft multifocal contact lenses on myopia progression. The Data Safety Monitoring Committee holds annual in-person meetings and conference calls at the 6-month interval between in-person meetings. On average, the enrolled subjects had approximately 2.50 D myopia with 20/20 best-corrected visual acuity at distance and near (Table 6). Enter the password that accompanies your username. For general information, Learn About Clinical Studies. If the subject missed any letters of the top line on the chart, the subject moved to 2 m and started the process again. All subjects also performed binocular high-contrast distance visual acuity while wearing +2.50-D add multifocal contact lenses with the spherical overrefraction in a trial frame. All subjects were randomly assigned to wear Biofinity, Biofinity Multifocal D with a +1.50-D add power, or Biofinity Multifocal D with a +2.50-D add power contact lenses. Anstice NS, Phillips JR. Effect of Dual-focus Soft Contact Lens Wear on Axial Myopia Progression in Children. In summary, the BLINK study is a 3-year randomized clinical trial to investigate the effect of commercially available soft multifocal contact lenses on myopia progression in children. Moisture Rich Ingredient, Surface Treatment etc. Subjective at-home ratings for ease of lens handling for insertion, using a 0-10 scale (0-Very difficult, 10 - Very easy). Factors Preventing Myopia Progression with Orthokeratology Correction. Convergence Insufficiency Treatment Trial (CITT) Study Group. Mean SD are presented for continuous variables and number (proportion) for categorical data. A Randomized Trial using Progressive Addition Lenses to Evaluate Theories of Myopia Progression in Children with a High Lag of Accommodation. Cheng X, Xu J, Chehab K, et al. The trial is registered with ClinicalTrials.gov ({"type":"clinical-trial","attrs":{"text":"NCT02255474","term_id":"NCT02255474"}}NCT02255474). The .gov means its official. Axial measurements were repeated until five readings without a poor-quality warning indicator or red highlight indicating implausible measurements were obtained. official website and that any information you provide is encrypted With up to 30 consecutive days of wear from just one pair of lenses, these are comfortable, affordable and securely-fitting lenses that you can rely on for crisp, clear vision each day. Percent slowing = (0.37 0.25)/0.37 = 32.4%. The purpose of this analysis is to compare ocular shape change among the two add powers of soft bifocal lens wearers and single-vision contact lens wearers using data from the 1-, 2-, and 3-year visits. In more than half of the soft multifocal contact lens myopia control studies, subjects wore multifocal contact lenses for 1 year or less, and none of the subjects wore treatment for more than 2 years. All vertical targets were placed on the wall in the appropriate location except the 30-degree inferior target, which was located within the housing of the autorefractor. Walline JJ, Greiner KL, McVey ME, et al. All distance targets were created by a laser pointer on the wall. Berntsen DA, Sinnott LT, Mutti DO, et al. All sample size calculations were performed using PASS 2005 software using = 0.05 and = 0.20 (power = 80%). Neovascularization and corneal scars are the result of previous hypoxia, infection or inflammation and are therefore not active. Subjects were encouraged to wear their contact lenses during the day as often as they could comfortably do so (no extended wear), but they were also reminded that they could wear their glasses any time they wished. This article provides the baseline characteristics of the subjects enrolled in the BLINK study and details the methods used in the investigation.
