Summary
Multifocal contact lenses show minimal peripheral myopic shift, suggesting current designs may need larger optical zones and better depth of field control for effective myopia progression management.
Area of Science:
- Ophthalmology
- Optometry
- Vision Science
Background:
- Multifocal soft contact lenses (MSCLs) are explored for myopia control, potentially by creating relative peripheral myopia.
- Understanding the peripheral optical effects of MSCLs is crucial for evaluating their efficacy.
Purpose of the Study:
- To objectively evaluate the peripheral optical effects of commercially available MSCLs using wavefront measurements.
- To assess how MSCLs influence refractive shift, peripheral image quality, and depth of field.
Main Methods:
- Two MSCLs (high/low add) and a monofocal lens were tested on four subjects.
- A scanning Hartmann-Shack wavefront sensor measured optics over a ±40° horizontal field.
- Image quality was assessed using the area under the modulation transfer function (MTF).
Main Results:
- MSCLs with 2 diopters add induced approximately 0.50 diopters of relative peripheral myopia at 30° nasally.
- Lens edge effects significantly degraded image quality at larger off-axis angles (>30°).
- Image quality was reduced and depth of field increased even at small angles (10°-15°).
Conclusions:
- The tested MSCLs produced a minimal peripheral myopic shift in subjects.
- Current MSCL designs may require larger optical zones and more controlled depth of field for significant myopia control effects.
- Objective wavefront analysis provides a method to evaluate MSCL optical performance.

01:16Focusing of Light in the Eye
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
01:20Anatomy of the Eyeball
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...
