LASIK after 40: is it still worth it? (2026)

Yes, LASIK can still fix distance vision after 40, but it cannot correct presbyopia, so most people will need reading glasses. Options include monovision LASIK, ICL (now FDA-indicated to age 60 in the US) or, from the mid-40s, lens replacement that also prevents future cataract.

LASIK after 40: is it still worth it? (2026)

Is LASIK worth it after 40?

It can be, if you understand what it will and will not do. LASIK and SMILE correct the focus of the cornea for distance. They do not stop the natural lens inside the eye from stiffening with age, which causes presbyopia, so after about 40 most people will still need reading glasses.

The AAO says you may start to notice presbyopia shortly after age 40 and states plainly that LASIK cannot correct it. If you are nearsighted now, you may currently read by taking your glasses off; after distance LASIK you will lose that and need readers instead. Facts on this page were checked on 1 November 2026.

What changes in your eyes after 40?

Three things start to matter more:

  • Presbyopia: near focus gets harder, usually first noticed with small print or dim light
  • Dry eye: more common with age, and the most common side effect of LASIK; see dry eye after LASIK
  • Early lens changes: the beginnings of cataract can appear, and the AAO lists a cataract affecting vision as a reason not to have LASIK

A thorough exam checks all three before recommending a procedure. See pre-op eye exam in Korea.

What are my options after 40?

The right choice depends on your age, prescription, lens health and how you use your eyes.

Option How it works Often suits Trade-off
Distance LASIK or SMILE Both eyes corrected for distance 40s, healthy lens, happy to wear readers Reading glasses for near
Monovision LASIK One eye distance, one eye slightly nearsighted People who tolerated monovision contacts Less depth perception; not for everyone
ICL Lens implanted in front of your natural lens High myopia, thin corneas, under 60 (US label) Readers still needed; intraocular surgery
Refractive lens exchange Natural lens replaced with an implant Mid-40s and over, hyperopia, early lens changes Bigger surgery; lens choices affect night vision

See monovision LASIK in Korea, refractive lens exchange in Korea and multifocal lenses in Korea.

Does your prescription type change the answer?

Yes, quite a lot. Presbyopia affects people differently depending on whether they are nearsighted, farsighted or already need little correction.

  • Nearsighted in your 40s: you may read comfortably without glasses today. Full distance correction gives you clear distance vision but means readers for close work. Some people choose to leave one eye slightly nearsighted (monovision) for this reason.
  • Farsighted in your 40s: presbyopia often arrives earlier and feels stronger, because the eye already struggles at near. Laser can treat moderate hyperopia, but lens-based options are discussed more often from the mid-40s.
  • Mild prescription only: if your distance vision is nearly fine and your main problem is reading, laser vision correction may add little. Reading glasses or a presbyopia procedure may be the real question.

Think about how you spend your day. Someone who drives a lot at night will weigh glare and halos differently from someone who reads and uses screens for hours. Tell the surgeon which distances matter most to you, so the plan fits your life rather than a chart. Read about the condition in presbyopia and hyperopia.

How does monovision LASIK work?

The surgeon corrects your dominant eye for distance and leaves the other slightly nearsighted for reading. The AAO notes you need to adapt, may lose some ability to judge distance or speed, and that monovision is not for everyone. It suggests trying monovision with contact lenses before having LASIK. If you cannot adapt, the near eye can sometimes be treated again for distance.

When does lens replacement make more sense than LASIK?

Lens replacement is usually discussed from the mid-40s onward, especially for farsighted people or those with early lens changes. The AAO says lens implants can give a full range of vision in each eye. Replacing the lens also means you will not develop a cataract later, because the natural lens is gone. Compare lens types in monofocal vs multifocal IOL and RLE vs ICL.

Is ICL an option after 45?

It can be. In 2026 the US FDA widened the EVO ICL age indication from 21–45 to 21–60, for −3.00 to −20.00 D of myopia. Presbyopia still develops, and the natural lens remains, so cataract surgery may be needed later. See ICL surgery in Korea.

How much do these options cost in Seoul?

Seoul ranges checked in 2026: LASIK ₩1.5M–₩2.5M for both eyes (approximately $1,100–$1,900), SMILE ₩2.2M–₩3.2M for both eyes and ICL ₩4M–₩6.5M for both eyes (approximately $2,900–$4,700). Lens surgery is priced per eye: cataract surgery runs about ₩1.5M–₩7.5M per eye depending on the lens. See cost of presbyopia surgery in Korea.

What should I ask my surgeon?

  • How healthy is my natural lens, and is there any early cataract?
  • Will I need reading glasses after this procedure, and when?
  • Can I trial monovision with contact lenses first?
  • How will this choice affect future cataract surgery?
  • How is my tear film, and how will you manage dry eye?

FAQ

Frequently asked questions

Is 40 too old for LASIK?

No. There is no upper age limit as such, but after 40 presbyopia means you will likely need reading glasses after distance LASIK. Your lens health matters more than your age.

Will I need reading glasses after LASIK at 45?

Most likely, yes, because LASIK cannot correct presbyopia. Monovision can reduce the need for readers if you adapt to it.

Is monovision LASIK a good idea?

It suits some people well and others not at all. The AAO suggests trying monovision with contact lenses first to see whether you adapt.

Should I get lens replacement instead of LASIK at 50?

Often it is worth discussing, especially if you are farsighted or have early lens changes. Lens replacement also prevents a future cataract, but it is a bigger operation.

Can LASIK be done after cataract surgery?

Sometimes LASIK or PRK is used to fine-tune vision after cataract surgery. Your surgeon will advise based on your cornea and the lens implant.
