LASIK, short for “Laser-Assisted In Situ Keratomileusis,” has gained immense popularity as a vision correction procedure. But you may be wondering how old you need to be to undergo this life-changing surgery.

In this blog, we will answer the question, ‘How old do you have to be for LASIK?’ and help you understand the factors that determine candidacy, especially for younger individuals.

Understanding LASIK

LASIK is a surgical procedure that reshapes the cornea to correct refractive errors such as nearsightedness, age-related farsightedness, and astigmatism. It’s a minimally invasive procedure that offers the possibility of reducing or eliminating the need for wearing glasses or contact lenses. But what is the best age to consider LASIK as an option?

Age Requirements for LASIK

How old do you have to be for LASIK? The age may vary depending on the clinic and surgeon’s preferences. In Australia, the minimum age for LASIK is usually 21 years, as patients below this age may experience changes in their vision due to natural growth.

Ideal candidates are often between the ages of 20 and 40, as their vision is more likely to have stabilised.

Stability of Vision

To determine if you are a suitable candidate for LASIK, it’s crucial to have a stable prescription. This stability is a key factor in the success of the procedure. Your prescription should remain relatively unchanged for at least a year before considering LASIK.

Frequently Asked Questions

Below you can find our most frequently asked questions about ‘How old do you have to be for LASIK eye surgery?’

Is laser eye surgery worth it if you have astigmatism?

Absolutely! LASIK can effectively treat astigmatism and help with clear vision. It’s essential to consult with us to determine if you are a suitable candidate.

What astigmatism is too high for LASIK Surgery?

The suitability for LASIK varies depending on the individual and their eye characteristics. In some cases, individuals with high astigmatism may not be ideal candidates for LASIK but may benefit from alternative procedures such as PRK or implantable collamer lenses.

How successful is LASIK eye surgery for astigmatism?

LASIK has a high success rate for astigmatism corrective surgery. The outcome depends on various factors, including the severity of astigmatism and the individual’s eye health. A consultation will provide you with a clearer understanding of your specific case.

Is refractive lens exchange the same as LASIK?

No, refractive lens exchange (RLE) is not the same as LASIK. LASIK reshapes the cornea to correct vision, while RLE involves replacing the eye’s natural lens with an artificial one to correct vision issues, typically used for individuals with age-related changes in the natural lens or high degrees of refractive error.
