When prescribing myopia controlling contact lenses for children, daily disposables are the safest modality. Only spherical corrections are available, though, which can impact lens selection for children with astigmatism. The NaturalVue Multifocal contact lens is suggested for up to 2D of astigmatism, much higher than is typical for spherical CL designs. Is is ‘masking’ astigmatism, or ‘partially correcting’ it instead?
The NaturalVue Multifocal contact lens is a daily disposable which may slow myopia. It is recommended for low astigmatism, as is typical for spherical contact lenses, but its unique optical profile has led practitioners to ask if it can be fit to patients with higher levels of astigmatism. Read this case which highlights the dynamics of a young visual system, using the fitting guide and finding the best solution for a very high myope.
If a child is wearing spectacles or using atropine as their primary myopia control treatment, which contact lens should we choose for sports? Is a myopia controlling contact lens needed if it will only be for occasional wear? Here we discuss the options and clinical considerations based on the individual patient.
The value and importance of axial length measurement in myopia control is growing. As you offer myopia control to more patients, you could start to consider which instrument to use to measure axial length. How do ultrasound and interferometry instruments compare in accuracy? What about the new generation combination instruments? Here we address the practicalities of axial length measurement.
This case study describes two examples of myopia and axial length mismatch – a low myope with long eyes and high myope with short eyes. With axial length becoming more available and crucial in myopia management, it’s important to understand that the relationship between refraction and axial length isn’t always consistent. Find out more regarding the other ocular components that can influence refractive error.
How do you manage your young patient when their ophthalmologist appears to have advised parents against orthokeratology? How should you communicate with the ophthalmologist about orthokeratology? This clinical case explores the aspects of safety, efficacy and benefits, including detail on the comparison of short-term risks of contact lens wear with the long-term risks of myopia.
How do you approach communicating with parents about myopia when they reject even standard single vision correction for their child? This is especially concerning given that even a full strength single vision correction is a better choice than under- or un-correction of myopia – for both myopia progression as well as the child’s functional abilities. This clinical problem is more common than you might think, especially in some regions of the world.
How does the normal emmetropization process in childhood influence refraction shifts in pseudophakes? Should a myopic shift in a pseudophakic child be viewed as myopia progression? How should they be managed and is myopia control needed? This blog covers important considerations in managing these atypical myopes.
When is a hyperope actually a myope? This case presents an aphakic patient with Marfan syndrome and an extremely long axial length, who needs to be managed like a high myope. This post also discusses a variety of pharmacological approaches to myopia management, based on a fascinating case presented in the subsequent Facebook discussion.
