Can Presbyopia Develop after Vision Correction Surgery?

 What Causes Presbyopia (age-related farsightedness)?

Presbyopia is caused by the aging of the crystalline lens, which makes it harder to focus on nearby objects. This is why people in their mid-40s often start having difficulty with near vision.

Presbyopia occurs similarly in most people as they age.

However, some people can have clear near vision even in their 60s or 70s, while others struggle to see nearby objects in their late 30s and start using reading glasses.

This difference usually depends on whether a person is nearsighted or farsighted.

Difference in Normal Vision?

People with emmetropia(normal vision) can see distant objects clearly. However, they need the help of the crystalline lens to focus on nearby objects.

Those with myopia can see close objects clearly without relying much on the lens. On the other hand, people with hyperopia require the lens’ help.

As we age, everyone experiences lens aging at a similar rate. However, the onset of presbyopia is usually noticed in the order of hyperopia → emmetropia → myopia.

In conclusion, undergoing vision correction surgery does not cause presbyopia to come earlier, nor does it accelerate the aging of the lens.

Depending on the surgery results — whether the person ends up with emmetropia, myopia, or hyperopia — the onset of presbyopia may vary by about 1 to 2 years.
