Cataract surgery stands as one of the most successful and common procedures in modern eye care. Your choice between monofocal plus vs EDOF lenses cataract options in London can affect your quality of life by a lot. Modern cataract surgery presents innovative lens technologies with unique visual benefits. Monofocal-plus lenses deliver sharp distance vision and better intermediate clarity. These lenses add about one extra line of intermediate vision on standard eye charts. EDOF (Extended Depth of Focus) lenses create a smooth range of vision that has minimal glare or halos. They provide clear vision from distance to mid-range and functional near vision.
Studies reveal that 85% of patients with EDOF lenses needed glasses less often than those with traditional monofocal lenses. Each lens type brings its own advantages. Monofocal plus lenses lead to high patient satisfaction because they provide natural-looking vision and predictable outcomes. The EDOF technology extends the focal point smoothly across multiple distances. These lenses work well even in low-light conditions. Precision Vision London helps patients understand these premium intraocular lens options for cataract surgery. This piece gets into the differences between these advanced lens options to help you make the right choice for your vision needs.
How Monofocal Plus and EDOF Lenses Work
Understanding how premium intraocular lenses work will help you choose between monofocal plus vs EDOF cataract options in London. These innovative technologies use different approaches to meet your visual needs after surgery.
Monofocal Plus IOL: Enhanced distance with limited intermediate support
The UK market welcomed monofocal plus IOLs in 2019. These lenses feature a higher-order aspheric profile on their anterior surface, and their power gradually increases from the periphery to the centre. They boost far and mid-distance vision without splitting light like multifocal designs. Clinical studies reveal better performance at intermediate distances compared to standard monofocals. The mean binocular uncorrected intermediate visual acuity reaches 0.17±0.12 versus 0.32±0.11 for standard options. Patients need lower reading add power (1.40 D compared to >2.00 D with standard monofocals).
EDOF Lens Technology: Extended range from distance to intermediate
EDOF (Extended Depth of Focus) lenses take a unique approach. Rather than focusing light at specific points, EDOF technology creates one elongated focal point that extends across distances. This continuous range of vision eliminates overlapping images that cause halos in multifocal designs. Optical bench studies show EDOF lenses have a flatter defocus curve compared to monofocal and monofocal plus options. The negative depth of focus at 0.2 logMAR measures -1.81D versus -1.28D for monofocal plus lenses.
Light Distribution and Contrast Sensitivity Differences
The main difference between these technologies lies in light distribution. Monofocal plus designs keep about 85% of their surface similar to standard monofocals, which maintains excellent contrast sensitivity. EDOF lenses distribute light energy in a linear way along an extended focal range. This means EDOF options might show a slight reduction in contrast sensitivity, especially in low-light conditions. Both lens types deliver high-quality vision with minimal visual disturbances compared to multifocal alternatives. Our surgeons at Precision Vision London carefully evaluate which premium intraocular lens matches your visual needs and lifestyle best.
Visual Performance in Real Life
Ground visual performance matters more than technical specifications for London patients choosing between monofocal plus vs EDOF cataract options. These lenses boost daily living in different ways.
Distance Vision: Comparable clarity in both lenses
Clinical studies confirm both lens types provide excellent distance vision clarity. Research shows 98% of EDOF patients achieve 20/20 or better binocular distance vision. Monofocal plus patients typically experience sharp, clear distance sight. Binocular uncorrected distance visual acuity measurements reveal similar results – EDOF achieves approximately -0.09 logMAR, and monofocal plus performs similarly.
Intermediate Tasks: EDOF advantage for screen use and cooking
EDOF lenses shine at intermediate distances, which helps with computer work, cooking, and shopping. Studies show EDOF lenses deliver approximately 97% of patients with 20/20 or better intermediate vision and create smoother transitions between distances. The technology adapts well to modern lifestyles and helps with depth perception during everyday activities like reading maps or using devices.
Near Vision: Why both may still need reading glasses
Both lens types have limitations for close work. About 58% of EDOF patients achieve 20/20 or better for near vision, but most need reading glasses for very small print. Monofocal plus users also need reading support for fine print and detailed tasks like sewing.
Night Vision and Glare: Monofocal Plus vs EDOF in low light
Monofocal plus lenses stand out with:
- Minimal halos and glare perfect for night driving
- Better contrast in dim conditions
EDOF technology has improved significantly. Studies show only 1% of patients report being “very much” bothered by halos, and about one-third report no halos at all. Both lenses maintain good contrast, which helps patients recognise faces in different lighting conditions.
Suitability Based on Eye Health and Lifestyle
Choosing the right premium intraocular lens depends on your eye health and daily activities. Our surgeons at Precision Vision London assess several significant factors before recommending monofocal plus vs EDOF cataract options.
Dry Eye and Contrast Sensitivity Considerations
Patients with chronic dry eye need extra attention because tear film instability affects both measurements and outcomes. Treatment with warm compresses and lubricants before surgery substantially improves results. Monofocal plus lenses better preserve contrast sensitivity (knowing how to distinguish objects from backgrounds), which makes them ideal for early macular changes.
Active Lifestyles: Sports, driving, and travel
Your choice of lens varies based on your sports activities:
- Monofocal plus designs work best for golf and distance sports
- EDOF technology helps with creative activities that need intermediate vision
Night driving needs careful thought since monofocal plus lenses show fewer halos and give better contrast in dim conditions. Curious which lens is right for you? Book your personalised Cataract Surgery consultation with our Harley Street team today.
Visual Goals: Spectacle independence vs clarity
Your priorities help determine the best choice. EDOF lenses give you more visual flexibility, particularly for intermediate tasks like computer work. Monofocal plus options deliver exceptional clarity though you might need reading glasses occasionally.
Who Should Avoid EDOF or Monofocal Plus?
Some eye conditions need extra caution with premium lenses. Patients with advanced glaucoma, macular degeneration, or severe dry eye should think over standard monofocal options. EDOF lenses might not be the best choice for people with irregular corneas or those who drive frequently at night.
Cost, Coverage and Long-Term Value
Money matters significantly when choosing between monofocal plus vs EDOF cataract options for London patients. Our team at Precision Vision London believes in giving you clear details about costs and value.
