![]() The minimum absolute degree of refractive error most practitioners considered necessary to prescribe for a child was −0.50 D.Consistent with being the preferred treatment options, most practitioners indicated that 0.01 per cent atropine and orthokeratology were efficacious for modulating childhood myopia progression.Relative to a single‐vision distance full‐correction, practitioners considered orthokeratology (85.4 per cent), low‐dose (0.01 per cent) topical atropine (54.4 per cent) and soft defocus contact lenses (40.6 per cent) as the three most effective modalities.They said that, based on current best‐available evidence, topical anti‐muscarinic receptor antagonists appear to be the most promising standalone agent for attenuating myopic progression in children. ![]() ‘Clinical guidelines may be of value for assisting practitioners in making clinical decisions based upon the current, best‐available research evidence.’ ![]() ‘Current optometric practices reflect the inconclusive nature of several key aspects of the evidence for childhood myopia management,’ they concluded. The authors were Optometry Australia members, optometrists Amanda Douglass, Peter Keller and Laura Downie from the University of Melbourne Department of Optometry and Vision Science and Centre for Eye Research Australia ophthalmologist Professor Mingguang He. The online survey about knowledge, perspectives and clinical practices of Australian optometrists in relation to childhood myopia was sent to Optometry Australia members in 2016 and results appear online in the March issue of Clinical and Experimental Optometry, out now. Low‐dose (0.01 per cent) atropine was the most frequently used, being prescribed at least ‘some of the time’ by about 20 per cent of practitioners. Respondents indicated prescribing topical atropine relatively infrequently. ![]() Of contact lens corrections, orthokeratology was the most popular approach, with almost one in two respondents indicating they would prescribe this modality at least half of the time. Spectacle prescribing was despite most optometrists identifying orthokeratology, low‐dose (0.01 per cent) topical atropine and soft peripheral defocus contact lenses as three potentially more effective therapeutic interventions for modifying childhood myopia progression. This form of correction was less likely to be prescribed by respondents with an interest in myopia and in independent practice.įor other spectacle options, the next most common response was progressive addition lenses, with about one in five practitioners indicating they at least ‘mostly’ prescribe this option. The survey of 239 optometrists found the most common approaches to management were single‐vision distance (full correction) spectacles with more than 50 per cent of respondents indicating they would ‘always’ or ‘mostly’ prescribe this modality. Prism lenses are prescribed for patients who suffer from severe binocular vision difficulties and double vision, most commonly resulting from:Ĭontact an eye doctor near if you or a family member suffer from any of these signs above, prism lenses may be the solution to eliminate these signs.Australian optometrists appear aware of emerging evidence around myopia treatment, but are not routinely adopting measures that have not yet received regulatory approval for modulating childhood myopia progression, the first myopia management survey in Australia shows. This helps the eyes to perceive images in a way that single vision can be achieved- improving binocular vision, and reducing double vision, headaches, reading difficulties, and more.Ī prism lens can be base out, base in, base up, or base down, depending on the way the eye is turned or misaligned. Prisms “trick” the eye into believing that an object is in a different location in order to improve eye alignment. They do not contain any focusing power, and therefore cannot correct any refractive errors. Prism lenses are special lenses that are prescribed by eye doctors and infused into regular lens prescriptions. Prisms, by definition, are triangular in shape, and made of plastic or glass for the purpose of dispersing light into a spectrum, or changing the direction in which light is reflected. One of the most common uses for an eye doctor prescribing prisms is to treat a condition known as Binocular Visual Dysfunction (BVD). Prism lenses can be effectively used to treat vision conditions, such as double vision and other binocular vision difficulties.
