Are You Suitable for Laser Eye Surgery?

Laser eye surgery can be a life-changing procedure that can help improve the eyesight of people suffering from different vision problems. However, not everyone will have a problem that can be resolved by laser eye surgery, or they may not be the right candidate due to a number of other health considerations.

To see whether you are a suitable candidate for laser eye surgery, we have compiled a list of important considerations below before you book an appointment. If still in doubt, the best thing to do is consult a doctor or vision specialist.

Who Can Have Laser Eye Surgery?

LASIK laser eye surgery is a form of refractive surgery that uses a laser to reshape the cornea at the front of your eye. The cornea is the clear film that covers your pupil and is vital for light to properly enter the eye and be collected correctly against the retina.

Refractive surgery, therefore, targets vision issues that are caused by irregularities in the cornea. If you already have glasses or contact lenses and know that one of these common eye sight problems is the cause, then laser eye surgery might be suitable for you.

Ideal candidates typically:

• Have myopia, hyperopia, or astigmatism within treatable ranges
• Maintain stable prescriptions for one to two years
• Have sufficient corneal thickness and regular corneal shape
• Do not have progressive eye diseases or uncontrolled systemic conditions

Similarly, if you suspect that you have one of these conditions because you are suffering from blurry vision, difficulty seeing at night, eyestrain and headaches, then you might wish to consult with an eye care specialist to diagnose your condition and discuss whether laser eye surgery is an option.

Who Are Not Eligible for Laser Eye Surgery?

Alternatively, there are some people who might not be suitable to undergo laser eye surgery despite having hyperopia, myopia or astigmatism.

Laser eye surgery requires stable eyesight and general good health to lower the possibility of complications and improve the chance of a successful procedure. Therefore, some people who may not be suitable include:

• Someone who has a varying refraction error. If you find that you need to change your glasses regularly or have recently undergone significant changes in eyesight (one-half dioptre or more), then your vision may not be stable enough to allow for laser eye surgery. Approximately one to two years of stable vision is required before laser eye surgery becomes an option.
• Someone who has a very high refractive error. If you have above-average levels of hyperopia or myopia, then laser eye surgery such as LASIK might not be suitable for you. You should talk to your eye care specialist for other surgical and non-surgical options.

There are also some people who might not be suitable due to other considerations:

• Other eye or health problems. If you have other eye conditions or an autoimmune disorder such as keratoconus, Lupus or diabetes, then you might not be suitable for eye surgery and need to discuss your options with your doctor.
• Candidates younger than 20 years old. People’s eyesight often continues to change until they are 20 years old, thus laser eye surgery is usually not recommended until they are older and maintain a stable subscription for longer than 12 months.
• Women who are pregnant or lactating. It is common for women who are lactating or pregnant to suffer from temporary changes in eyesight due to hormonal shifts in the body, thus, they wouldn’t be recommended laser eye surgery until the eyesight problem is proven to be a long-term condition.

As such, eligibility is determined through detailed diagnostic testing rather than age or prescription alone. A personalised assessment ensures laser eye surgery is recommended only when it offers a clear benefit with acceptable risk.

Can I Get Laser Eye Surgery For Reading?

If reading glasses are required due to presbyopia, the age-related loss of near focusing ability that typically begins in the early to mid-40s, standard laser eye surgery may not fully eliminate the need for glasses. Presbyopia is not caused by corneal shape, but by the natural stiffening of the eye’s internal lens.

That said, some laser treatments can still help certain patients. Options such as monovision laser correction, where one eye is optimised for distance and the other for near vision, may reduce reliance on reading glasses. This approach requires careful assessment and adaptation, as not everyone tolerates the visual balance comfortably.

If reading difficulty is caused by hyperopia (farsightedness) rather than presbyopia, laser eye surgery may significantly improve near vision. A comprehensive eye assessment is essential to determine the cause of reading problems and whether laser correction is appropriate.

When Can I Get Laser Eye Surgery?

Timing matters when it comes to laser eye surgery. The procedure is safest and most effective when vision has been stable for a sustained period.

Most candidates are considered once their prescription has remained unchanged for at least 12 to 24 months. Vision that continues to shift increases the likelihood that results will regress over time.

Age also plays a role. Laser eye surgery is generally recommended for adults aged 20 and over, once natural eye development has stabilised. Upper age limits are less strict, but older patients may have other eye conditions, such as cataracts or presbyopia that influence suitability and outcomes.

Temporary physiological changes can also affect timing. Pregnancy, breastfeeding, recent hormonal changes, or uncontrolled health conditions may delay eligibility until vision stability returns. A laser consultation helps determine whether now is the right time or whether waiting would lead to better long-term results.

Find Out If Laser Eye Surgery Is Right for You

Determining whether laser eye surgery is suitable depends on more than just your prescription. Vision stability, eye health, lifestyle, and long-term expectations all play an important role in achieving a safe and successful outcome.

At personalEYES, suitability for laser eye surgery is assessed through comprehensive diagnostic testing and personalised clinical advice. Every recommendation is based on whether treatment is appropriate for your eyes, not on a one-size-fits-all approach.
