A separate, current article sign-off has not yet been recorded. [How review works](https://eyehealthguide.org/reviewers/) · [Official biography & credentials](https://mohamedmohyudin.co.uk/author/mohamed-mohyudin/) Quick answer This page helps you prepare questions for your cataract surgeon about lens options. You answer a few optional prompts about daily life and preferences; nothing here chooses a lens for you. Only your surgeon can advise after measuring your eyes. You will get a personalised list of questions to take to the appointment, plus plain explanations of every common lens family. ### On this page ⌄ 1. Questions about your daily life 2. The common lens families 3. Questions to ask your surgeon 4. Read next Choosing a lens implant is one of the most personal parts of cataract surgery. This page will not tell you which lens to have — only your surgeon can do that after measuring your eyes and reviewing your eye health. What it will do is help you work out what matters in your daily life, and turn that into a clear list of questions to take to the appointment. Every common lens family is explained below so you can read them in your own time. This is a preparation aid for your conversation with your surgeon. It does not choose a lens for you and does not replace clinical advice. ## Questions about your daily life Your answers stay in this browser. They are never sent anywhere and are not stored by Eye Health Guide. ## The common lens families ### Monofocal A monofocal lens is set for one main distance — usually far. Reading and close work typically still need glasses. It is the most widely used option after cataract surgery, with a long track record, and tends to cause fewer glare and halo effects than lenses that split focus across distances. - Clear, predictable focus at the distance it is set for - Usually fewer glare and halo effects than multifocal designs - Glasses are commonly still needed for other distances - Does not, by itself, correct meaningful astigmatism ### Toric monofocal A toric monofocal lens corrects astigmatism as well as replacing the cloudy cataract. Like a standard monofocal, it is usually set for one main distance, so you may still need glasses for other tasks. Alignment of the lens in the eye matters for the astigmatism correction to work as intended. - Can sharpen vision when astigmatism is part of the picture - Still a single-distance design for most people - Alignment and stability of the lens affect the result - Availability and funding can vary by clinic and pathway ### Extended depth of focus (EDOF) An extended depth of focus (EDOF) lens aims to give a broader range of useful vision than a standard monofocal — often clearer intermediate distance for screens and dashboards — while reading glasses are still commonly needed. Glare or halos can still occur, and how noticeable they are varies from person to person. - Often helpful for intermediate tasks such as computer work - May reduce glasses use compared with a distance-only monofocal for some people - Reading glasses are still commonly needed - Some people notice glare, halos or reduced contrast, especially at night ### Multifocal or trifocal Multifocal and trifocal lenses split light to support more than one focus distance, aiming to reduce dependence on glasses for distance, intermediate and near tasks. Spectacle independence is never guaranteed. Some people notice glare, halos or reduced contrast, especially at night, and these effects can take time to adapt to. - Designed to support more than one working distance - Can reduce glasses dependence for many everyday tasks for some people - Spectacle independence is never guaranteed - Glare, halos or lower contrast can be more noticeable, particularly for night driving ### Monovision Monovision sets one eye mainly for distance and the other mainly for near, using monofocal lenses. It can reduce glasses use for many everyday tasks, but depth perception and night driving can feel different, and not everyone adapts. A contact-lens trial beforehand, where offered, helps you judge whether it suits you. - Can lessen glasses use without a multifocal optic - A contact-lens trial, where offered, lets you test the feel first - Depth perception and night driving can feel different - Not everyone adapts; some people prefer both eyes set the same way ## Before you read your questions Use the list below as a prompt sheet for your appointment — not as a decision. Read the lens family explanations so the words feel familiar, then ask your surgeon how each option relates to your measurements and eye health. Local public services differ in what they offer, and private pathways differ in cost and inclusions. Spectacle independence is never guaranteed. If something on this page conflicts with what your surgeon explains after examining you, follow your surgeon. ## Questions to ask your surgeon 1. After you measure my eyes, which lens families are realistic options for me to discuss — and what would rule any of them out in my case? 2. What glasses am I likely to need for distance, intermediate and near with each option we discuss? 3. Is spectacle independence guaranteed with any of the options available to me? 4. How would each option we discuss typically affect night vision, glare and halos? 5. What are the main trade-offs you would want me to weigh for my lifestyle? 6. If I am not happy with my vision after surgery, what can be done? 7. How do you choose the target focus for a monofocal lens in a patient like me? ## Read next ## Sources for this information These references support the information on this page.
