Lens Replacement vs LASIK After 45 (UK Guide 2026)

Is lens replacement or LASIK better after 45?

For patients over 45, lens replacement surgery is often a more suitable option than LASIK. While LASIK reshapes the cornea, lens replacement surgery (also known as refractive lens exchange) replaces the natural lens and can correct both distance and reading vision permanently.

What is the difference between LASIK and lens replacement surgery?

LASIK and lens replacement surgery are both vision correction procedures, but they work in different ways.

• LASIK reshapes the cornea using a laser to correct distance vision
• Lens replacement surgery (RLE) replaces the eye’s natural lens with an artificial intraocular lens

Lens replacement surgery is also technically the same procedure as cataract surgery, but performed earlier to improve vision rather than treat a cloudy lens.

Who is suitable for LASIK vs lens replacement?

LASIK is typically suitable for:

• Patients under 45
• Those with stable vision
• Patients without presbyopia (no reading glasses needed)

Lens replacement surgery is typically suitable for:

• Patients aged 45 and over
• People who rely on reading or multifocal glasses
• Patients with presbyopia, astigmatism or early cataract
• Those not suitable for LASIK
• Patients looking for a long-term or permanent solution

Key benefits: LASIK vs lens replacement

LASIK

• Quick procedure
• Fast recovery
• Effective for distance vision

Lens replacement surgery

• Corrects both distance and near vision
• Eliminates the need for reading glasses
• Long-term solution (does not wear off)
• One-time procedure
• Prevents future cataracts

Why LASIK may not be suitable after 45

After the age of 45, most people develop presbyopia — a natural loss of near vision. LASIK does not prevent or fully correct this condition.

This means that even after successful LASIK, many patients still need reading glasses later in life.

Cost comparison (UK vs Prague)

The cost of both procedures varies significantly depending on location.

• LASIK in the UK: typically £2,000–£5,000
• Lens replacement in the UK: £7,000–£14,000

In Prague, many UK patients choose lens replacement surgery abroad due to lower costs:

• Lens replacement in Prague: €1,900–€4,100 (£1,750–£3,600)

Even including travel, patients often save thousands compared to UK private clinics.

Is lens replacement surgery safer than LASIK?

Both LASIK and lens replacement surgery are considered safe when performed by experienced refractive eye surgeons.

However, lens replacement surgery is often recommended for older patients because it addresses the underlying cause of vision changes (the natural lens), rather than reshaping the cornea.

Which option is better after 45?

For most patients over 45, lens replacement surgery is considered the better long-term solution because it:

• Corrects both near and distance vision
• Eliminates the need for reading glasses
• Does not need to be repeated
• Prevents cataracts later in life

LASIK may still be suitable in selected cases, but it does not provide the same long-term benefits for patients with presbyopia.

What about ReLEx SMILE after 45?

ReLEx SMILE is a modern laser eye surgery that can be an alternative to LASIK for suitable patients. It is minimally invasive, does not involve creating a corneal flap and may reduce the risk of dry eyes.

However, like LASIK, ReLEx SMILE does not correct presbyopia (age-related loss of near vision). This means that most patients over 45 will still need reading glasses after the procedure.

For this reason, lens replacement surgery is often the preferred option for patients over 45 who want a long-term solution for both distance and near vision.

Why UK patients choose lens replacement surgery in Prague

Many patients from the UK and Ireland choose lens replacement surgery in Prague due to:

• Lower cost compared to UK clinics
• Experienced refractive eye surgeons
• EU-regulated medical standards
• Short travel time (around 2 hours from the UK)
• Well-organised patient care and coordination

FAQ

Final thoughts

For patients over 45, choosing between LASIK and lens replacement surgery depends on their vision needs and long-term goals.

While LASIK can improve distance vision, lens replacement surgery offers a more complete and permanent solution — particularly for those who want freedom from both reading and distance glasses.
