What Happens 20 Years After LASIK? Reading Glasses & Cataracts Explained

One of the most common questions people ask is, "Will my LASIK results last forever?" Or, "Will I need reading glasses or cataract surgery years after LASIK?"

In this video, we'll explain what really happens 20 years after LASIK and separate the effects of natural ageing from the results of laser vision correction.

Is LASIK Permanent?

Yes. LASIK permanently reshapes the cornea to correct refractive errors such as myopia, hyperopia, and astigmatism. The corneal tissue removed during the procedure does not grow back.

However, LASIK does not stop the natural ageing process of the eye. Over time, other parts of the eye continue to change, even though the corneal correction remains permanent.

Will You Need Reading Glasses?

Possibly, yes.

Around the age of 40 to 45, almost everyone develops presbyopia, a natural age-related condition in which the eye's natural lens becomes less flexible.

As a result, you may find it difficult to read small print, use your mobile phone, or perform close-up tasks without reading glasses.

This happens whether you've had LASIK or not. It is not a sign that your LASIK has failed.

Can Cataracts Develop After LASIK?

Yes.

LASIK does not prevent cataracts.

A cataract develops when the eye's natural lens becomes cloudy with age. Since LASIK reshapes the cornea—not the natural lens—you can still develop cataracts later in life.

The good news is that cataract surgery can usually be performed safely in patients who have previously undergone LASIK. Your eye surgeon may simply need additional measurements to calculate the most appropriate intraocular lens (IOL).

Can Vision Change Again After LASIK?

For most patients, distance vision remains stable for many years.

However, some people may experience:

• Mild prescription changes
• Dry eye symptoms
• Age-related presbyopia
• Cataracts later in life

These changes are usually related to the natural ageing of the eye rather than the LASIK procedure itself.

Will You Need Another LASIK Procedure?

Most patients never require another LASIK treatment.

In selected cases, where there is a small residual or recurrent refractive error and the cornea remains healthy, an enhancement procedure may be considered after a detailed evaluation by your ophthalmologist.

How Can You Protect Your Vision Long-Term?

Even after successful LASIK, it's important to:

• Have regular comprehensive eye examinations.
• Protect your eyes from excessive UV exposure.
• Control diabetes and blood pressure.
• Eat a balanced diet rich in leafy greens and antioxidants.
• Use lubricating eye drops if recommended.
• Seek medical advice if you notice sudden changes in vision.

Routine eye care helps detect age-related eye conditions early and keeps your vision healthy.

Final Thoughts

LASIK provides long-lasting correction for refractive errors, but it cannot prevent natural age-related changes such as presbyopia or cataracts. Needing reading glasses after 40 or developing cataracts later in life is a normal part of ageing—not a failure of LASIK.
