Question

How to fit for myopia control: What are two goals we shoot for when fitting in terms of power?

a) Achieving a myopic defocus in the peripheral retina
b) Reducing accommodative lag
c) Balancing central and peripheral refractive error
d) Ensuring a stable fit for at least 6 hours

Answer 1

When fitting for myopia control, the two goals we shoot for in terms of power are achieving a myopic defocus in the peripheral retina and reducing accommodative lag.

Step-by-step explanation:

Myopia, also known as nearsightedness, is a condition where distant objects appear blurry because the eye's optical power is too strong, causing the image to be focused in front of the retina. When fitting for myopia control, there are two goals we shoot for in terms of power:

1. Achieving a myopic defocus in the peripheral retina: By using specific types of contact lenses or glasses, we can create a slight blur in the peripheral vision, which has been shown to slow down the progression of myopia.
2. Reducing accommodative lag: Accommodative lag refers to the amount of extra focusing effort the eyes make, often resulting in increased myopia progression. The goal is to minimize this lag by ensuring the prescription is accurate and comfortable.

These two goals help in controlling myopia and reducing its progression.
