The American Academy of Ophthalmology (AAO) describes it as a lens with a single corrective zone that &#8220;extends&#8221; to cover more than one distance, rather than the several zones of a multifocal lens.<\/p>\n<p data-reveal>To count as &#8220;extended depth of focus&#8221;, a lens has to meet a strict clinical test. The AAO&#8217;s consensus criteria, summarised on EyeWiki, require a study of at least 100 patients in which the lens gives <strong>at least 0.5 dioptres more depth of focus than a monofocal lens<\/strong>, distance vision comparable to a monofocal lens, and good intermediate vision (20\/32 or better at 66 cm, arm&#8217;s length) in at least half of eyes.<\/p><div class=\"list-card\" data-reveal><h3>Three ways to extend focus:<\/h3><ol class=\"plain-ol\"><li><strong>Wavefront-shaping (non-diffractive).<\/strong> The lens surface gently stretches and shifts the light so that the focus becomes a band rather than a point. Alcon&#8217;s Vivity works this way, using what Alcon calls X-WAVE technology.<\/li><li><strong>Purely refractive.<\/strong> A smooth, continuous change in power across the optic extends the range of focus without diffractive rings. Johnson &amp; Johnson&#8217;s TECNIS PureSee is designed this way.<\/li><li><strong>Diffractive &#8220;echelette&#8221; or small-aperture designs.<\/strong> Older and alternative EDOF lenses use fine diffractive steps (TECNIS Symfony) or a tiny pinhole-like aperture (IC-8 Apthera). Small-aperture designs let in less light, which can make vision harder in dim conditions.<\/li><\/ol><\/div><p data-reveal><strong>Why &#8220;non-diffractive&#8221; matters.<\/strong> Multifocal and trifocal lenses split incoming light between distance, middle and near foci. That gives better reading vision, but the out-of-focus images can show up as rings or halos around lights at night. Non-diffractive EDOF lenses keep all the light in one stretched focus, so their pattern of night-time halos and glare is designed to be closer to that of a monofocal lens.<\/p>\n<p data-reveal><strong>Technology we use:<\/strong> <span class=\"ph\">{{EDOF lens models actually offered, e.g. Vivity \/ Vivity Toric, PureSee \/ PureSee Toric}}<\/span>, implanted in a fully equipped, Ministry of Health\u2013licensed operating theatre in Istanbul.

It stretches one focus into a continuous range, so you see clearly at distance and at arm's length. To qualify, it must give at least 0.5 dioptres more depth of focus than a standard monofocal lens.\"}},{\"@type\":\"Question\",\"name\":\"What are the disadvantages of EDOF lenses?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The main disadvantage is that most people still need reading glasses for small print: in the FDA studies, only 39\u201346% needed no glasses for near work. The Vivity lens also lowers contrast in dim light compared with a monofocal lens. Halos are less common than with trifocal lenses but can still occur, and EDOF lenses cost more than standard lenses.\"}},{\"@type\":\"Question\",\"name\":\"Which is the best EDOF lens?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"There is no single best EDOF lens; the best one is the lens that matches your eyes and your daily life. Vivity has slightly stronger intermediate results, while PureSee showed sharper distance vision and contrast comparable to a monofocal lens in its studies. Check that your surgeon measures your cornea, macula and astigmatism before recommending a model, and explains why it suits you.\"}},{\"@type\":\"Question\",\"name\":\"Is an EDOF lens better than a trifocal?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Neither is better for everyone. Trifocal lenses usually give better reading vision and more freedom from glasses, while EDOF lenses give a smoother range from distance to arm's length with fewer night-time halos. A 2024 Cochrane review found similar distance vision with both, and better near vision with trifocals.\"}},{\"@type\":\"Question\",\"name\":\"Will I need reading glasses with an EDOF lens?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Probably, for small print and long reading. In the FDA studies of Vivity and PureSee, 39\u201346% of patients needed no glasses for near work, so more than half used reading glasses at least some of the time. Mini-monovision, where one eye is set slightly short-sighted, can reduce this.\"}},{\"@type\":\"Question\",\"name\":\"How much does a Vivity lens cost?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The Vivity lens is priced as part of lens replacement surgery, not on its own. Premium lens replacement typically costs \u00a36,000\u201311,000 for both eyes in UK private clinics. With Laser Istanbul Clinic, EDOF lens surgery starts from {{\u00a3 price}} for both eyes, including your examination, surgery, lenses, medication, follow-up checks, interpreter and coordinator; hotel and transfers are extra.\"}},{\"@type\":\"Question\",\"name\":\"Can an EDOF lens correct astigmatism?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes. Both Vivity and PureSee are made in toric versions that correct corneal astigmatism at the same time. Your surgeon measures your astigmatism with corneal topography and biometry to decide whether you need one.\"}},{\"@type\":\"Question\",\"name\":\"Do EDOF lenses cause halos?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"They can, but less often than multifocal lenses. In the Vivity FDA study, fewer than 4% of patients reported severe or very bothersome visual disturbances at 6 months. Your surgeon explains what to expect for your eyes before you choose a lens.\"}},{\"@type\":\"Question\",\"name\":\"How long does an EDOF lens last?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The lens is implanted permanently and does not need replacing. Months or years later, the capsule behind it can become cloudy; a quick YAG laser treatment clears this. Because your natural lens has been removed, you cannot develop a cataract in that eye afterwards.\"}},{\"@type\":\"Question\",\"name\":\"How long do I need to stay in Istanbul for EDOF lens surgery?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Plan 5\u20137 days in Istanbul for both eyes, including your examination, surgery and check-ups.
