An enhanced monofocal IOL is a modern intraocular lens that extends the focus of a standard monofocal just enough to sharpen intermediate (arm's-length) vision, while keeping monofocal-quality distance vision and very low glare. At our partner clinics enhanced monofocal cataract surgery starts from £3,200 per eye, all-inclusive — around £300 more than a standard monofocal (£2,900) and less than an EDOF (£3,796) or multifocal (£4,300) lens. Most patients still use reading glasses for small print, but gain useful, natural-quality vision for screens, cooking and the car dashboard.
What is an enhanced monofocal lens?
A standard monofocal lens sets your eye to a single focal point — usually distance — giving excellent clarity for driving and TV, but leaving you dependent on glasses for anything closer. An enhanced monofocal (sometimes called a monofocal-plus) uses a subtly modified optic to stretch that single focus into a small range, so intermediate tasks become clearer without a second pair of glasses.
Crucially, enhanced monofocals are not multifocal lenses. They do not split light into separate near and distance images, so they avoid the rings, halos and night-time glare that a minority of multifocal patients notice. That makes them a reassuring choice for people who prioritise clean, natural vision — particularly night drivers — but would like a bit more range than a basic monofocal.
- Best for: sharp distance vision plus clearer screens and dashboards
- Glare/halos: comparable to a standard monofocal — very low
- Reading: glasses usually still needed for small print
- Astigmatism: toric versions available to correct it at the same time
Not sure which lens suits you? A cataract consultation with biometry maps your eyes and matches the right IOL to your lifestyle.

We offer the leading enhanced monofocal platforms. Your surgeon will recommend the best fit for your eye measurements and visual goals; toric versions are available across the range where you have astigmatism.
Have astigmatism? A toric enhanced monofocal corrects it in the same operation. Prefer an even wider range of glasses-free vision? Compare the EDOF and trifocal options, or read our Clareon TruPlus overview. Our monofocal vs multifocal cost guide weighs up the trade-offs.
How the surgery works
Fitting an enhanced monofocal IOL uses exactly the same gold-standard phacoemulsification technique as any modern cataract or lens replacement operation — the only difference is the lens implanted. It is a day-case procedure under local anaesthetic drops.
- Numbing drops are placed in the eye; you stay awake but feel no pain.
- A tiny self-sealing incision is made at the edge of the cornea.
- Phacoemulsification gently breaks up and removes the cloudy natural lens.
- Your enhanced monofocal IOL is folded, inserted and centred in the lens capsule.
- The eye is shielded and you rest briefly before going home the same day.
The same lens can be used in cataract surgery or in refractive lens exchange. Precise biometry measurements calculate the exact lens power for your eye. See the full implant lens options for how the families compare.
Recovery week-by-week
Recovery is the same quick, comfortable process as a standard monofocal — most people are back to everyday life within days.
Day of surgery
Vision is hazy for a few hours; an eye shield is worn the first night. Drops begin. No driving or heavy lifting.
Days 1-3
Vision clears noticeably; distance and intermediate sharpen. Mild grittiness settles. Most resume gentle activities.
Week 1
First review. Most are back to driving and work. You'll notice easier screen and dashboard vision.
Weeks 2-6
Vision refines fully. Any new reading-glasses prescription for fine print is finalised at around 4-6 weeks.
