Adult Disability Payment for Keratoconus

Yes. There is no list of qualifying conditions for Adult Disability Payment, so keratoconus is neither included nor excluded by name. What decides an award is how your vision affects 12 everyday activities, and keratoconus reaches several of them in ways that a sight test does not measure. It is also one of the conditions people most often under describe, because the number on the clinic chart looks better than the day actually is.

What keratoconus does that a sight test does not show

Keratoconus is a progressive thinning of the cornea, the clear dome at the front of the eye, which gradually bulges into a cone shape. Because the cornea does most of the eye's focusing, that change of shape distorts vision rather than simply blurring it. It usually appears in the teens or twenties and often gets worse over the years. Vision Scotland notes that it rarely leads to blindness, which is exactly why so many people with it assume they cannot claim.

The distinctive problems are these, and none of them are captured by a single acuity measurement.

• Distortion rather than blur. Straight lines bend, letters smear, and text can appear doubled or ghosted in one eye.
• Glare and light sensitivity. Headlights, low sun, supermarket lighting and screens produce starbursts and haloes that wash out what you are looking at.
• Fluctuation. Vision changes across the day with fatigue, dryness, lens tolerance and light conditions, so what you managed at 10am you may not manage at 6pm.
• Changing prescriptions. Glasses that worked six months ago no longer do, and at a certain point glasses stop helping at all.
• Asymmetry. Both eyes are commonly affected but rarely to the same degree, so one eye carries the day and tires.

Add the possibility of hydrops, a sudden and painful loss of vision when fluid enters a very thin cornea, which settles with time but can take months to do so, and you have a condition whose functional effect swings far more than its diagnosis suggests.

The clinic number problem

This is the single most common reason a keratoconus claim reads weaker than it is.

In clinic, with rigid or scleral lenses in and a well lit chart in front of you, corrected acuity can be recorded as reasonable. That figure then appears in any report Social Security Scotland requests. If your form has not explained the rest, a case manager reading "corrected to a good level" has no reason to picture anything difficult.

ADP is scored on function across the whole day and across a period, not on a best case measurement taken once in ideal conditions. Nothing about naming your best corrected acuity harms you, as long as the form also says what happens outside that ten minutes.

Which of the 12 activities keratoconus usually reaches

Ten daily living activities and 2 mobility activities are scored, each on the combined effect of everything you live with. These are the ones keratoconus most often touches.

Reading and understanding signs, symbols and words

The obvious one, and it is worth being specific rather than general. Name the things you cannot read even with your aids: a dosage on a box, a handwritten note, a price label, a bus number at distance, a departure board, a menu on a wall. If you rely on phone magnification, text to speech or asking someone, that is help and it belongs on the form.

Planning and following a journey

Frequently the strongest activity of all and one of the two mobility activities, so it carries its own points. If you cannot read signage or timetables, cannot follow an unfamiliar route without someone with you, avoid journeys after dark because of glare, or cannot drive when you once could, that all sits here.

Moving around

Distinct from planning journeys. This is about kerbs, steps, uneven pavement, bollards, crossings and unlit streets, and about the trips and near misses that come from distorted depth and contrast rather than from poor acuity.

Preparing food

Hobs, boiling water and sharp knives with unreliable vision are a safety question, not a convenience one. Reading packaging, checking use by dates, judging whether something is cooked and seeing what is in the pan all belong here. If you have burnt or cut yourself, record it.

Washing, bathing and dressing

Finding things, judging whether clothes are clean or inside out, seeing what you are doing in a mirror, and managing on lens free days. Needing someone to check you before you leave the house counts as help.

Managing therapy or monitoring a health condition

People with keratoconus routinely leave this blank, and it is often the easiest genuine points on the form. A lens routine is a daily medical task: cleaning, filling a scleral lens with saline without bubbles, inserting it, removing it, dealing with a torn or lost lens, plus drops, dry eye treatment and hospital appointments. If any part of that needs another person, or takes far longer than it should, say so.

Making budgeting decisions

Overlooked and often strong. If you cannot read bills, statements, prices or a card machine screen, or someone else has taken over managing your money because of your vision, this activity applies.

Engaging with other people face to face

Not seeing faces or expressions changes contact with people. Not recognising someone who greets you, missing visual cues, and pulling back from social situations because of glare or embarrassment are all functional effects, not personality.

Contact lenses are treatment, not a cure

This is where keratoconus claims are most often lost, and it is a misunderstanding rather than a rule.

Needing an aid to complete an activity is part of how the descriptors are scored. Rigid gas permeable and scleral lenses are aids in exactly that sense: they exist because glasses no longer work. Wearing them is evidence of the problem, not proof that it has gone away.

So describe both halves. What you can do with lenses in, and what remains true anyway.

• Wear time. Most people have a ceiling. Say what yours is and what the rest of the day looks like.
• Intolerance days. Dryness, an eye infection, hay fever or a bad fit can put lenses out of use for days at a time. Say how often, in days per week or per month.
• Mornings and nights. Before insertion and after removal you have no functional correction at all, which covers getting up, getting to the bathroom and anything at night.
• What lenses never fix. Glare and haloes usually persist. So does the effort of concentrating through distortion, and the headaches and fatigue that follow.

Glare, dark and the hours nobody asks about

Sensitivity to bright light is one of the recognised features of keratoconus, and it produces two effects that matter for the form.

The first is that bright environments are not the easy case. Sun on a wet pavement, oncoming headlights, strip lighting in a shop and a screen at full brightness can each wipe out usable vision for a period. The second is that the evening is worse rather than better. Many people with keratoconus stop driving at night long before they stop driving, and then stop entirely.

Write those hours into your answers. A form that describes a well lit weekday morning describes your best conditions, and the descriptors are not asking about your best conditions.

Cross-linking, ring segments and grafts

Treatment history is worth stating plainly, and it does not count against you.

Corneal cross-linking uses riboflavin drops and ultraviolet light to strengthen the cornea and slow or stop the condition getting worse. It is a stabilising treatment, not a restorative one. NHS patient information is explicit that you will still need glasses or contact lenses afterwards, so having had cross-linking does not mean your vision has been fixed. If you have had it, say when, and say what your vision has been like since.

Ring segments aim to reshape the cornea and improve how lenses fit. Corneal graft surgery, where donor tissue replaces the damaged cornea, is generally reserved for advanced cases, with long term success rates around 90 per cent according to Vision Scotland. What the form needs to know is the recovery, which is measured in many months rather than weeks, along with the drop regime, the appointments, the astigmatism that often remains and the lifelong possibility of rejection. A graft is a major treatment burden in itself and belongs under managing therapy.

None of this is a reason to delay applying. Entitlement is decided on how you are affected over the qualifying period, not on whether a future operation might help.

Registration, and why you should not wait for it

If you are registered sight impaired or severely sight impaired, name your Certificate of Vision Impairment early. It is objective and it saves explaining.

Most people with keratoconus will not have one, because the condition rarely reaches those thresholds. That is not a barrier. ADP is scored on functional effect, and there is no requirement to be registered, to have a particular acuity, or to have any diagnosis confirmed at all. Our guide to ADP for sight loss covers the registration question in more detail.

The reliability rule, which is where these claims are won

You are not scored on whether you can do something at all. You are scored on whether you can do it reliably, and all four of these must hold.

• Safely, in a way unlikely to cause harm to you or anyone else.
• To an acceptable standard.
• Repeatedly, as often as the activity is reasonably needed.
• Within a reasonable time period, no more than twice as long as someone without your condition would take.

Keratoconus engages every one of them. Cooking with distorted vision carries a real risk of burns and cuts whether or not you have been hurt yet. Reading a label by holding it an inch from one eye under a lamp is not an acceptable standard. A six hour lens ceiling is a direct answer to "repeatedly". And almost everything takes longer, because finding, checking and re-reading is the whole day. Our guide to the reliability criteria sets this out in full.

If it started when you were at school

Keratoconus commonly appears in the teens, so a lot of people meet the benefits system for the first time at 16. If you were getting Child Disability Payment, the move across is handled for you rather than being a fresh claim, and our guide to moving from CDP to ADP at 16 explains the process and the timing.

If you were never on Child Disability Payment, nothing about applying as an adult is harder for having had the condition for years. A long history is useful evidence, not a problem.

What to send with the application

Social Security Scotland has a duty to help you gather supporting information, and case managers can contact the people you name and request it themselves. You do not need to arrive with a folder.

Name your hospital eye service or corneal clinic, your contact lens optometrist, who fitted your lenses, and your GP. Recent letters that mention keratoconus, lens type, wear tolerance, cross-linking or graft history are worth including if you already have them. So is anything written by someone who sees the day rather than the eye: a partner, a support worker, a college disability adviser. Our supporting information guide covers what actually helps.

One practical note. If your only report is a clinic letter recording good corrected acuity, that letter alone can undercut you. It is not wrong and you should not hide it, but your own answers need to carry the day to day picture that the letter was never written to describe.

What an award is worth

ADP has two components, each scored separately. 8 to 11 points in a component gives the standard rate, 12 or more gives the enhanced rate. In 2026/27 the daily living component is £76.70 a week at the standard rate and £114.60 at the enhanced rate, and the mobility component is £30.30 standard and £80.00 enhanced. Full figures are in our guide to the 2026/27 rates.

If the determination goes against you

You have 42 days from the date of the determination letter to ask for a re-determination, and Social Security Scotland then has 56 days to respond. If that still does not go your way, you have 31 days to appeal to the First-tier Tribunal for Scotland, Social Security Chamber.

With keratoconus, a refusal often comes down to one of two things: a form written around acuity instead of around activities, or lens use read as evidence that the problem is solved. Both are fixable at re-determination, and adding the wear time, the intolerance days and the hours without lenses is usually the change that matters. Free help is available from Citizens Advice Scotland and local welfare rights teams.

Frequently Asked Questions

Can you get ADP for keratoconus in Scotland?

Yes. There is no list of qualifying conditions, so what decides an award is how your vision affects the 12 activities, not the diagnosis. Keratoconus commonly reaches reading, journeys, moving around, preparing food and managing treatment.

Do I need to be registered sight impaired to claim ADP for keratoconus?

No. Registration helps if you have it, but most people with keratoconus will not be registered and it is not a condition of entitlement. ADP is scored on functional effect, not on acuity or registration category.

Will wearing contact lenses stop me qualifying for ADP?

No. Needing an aid is part of how the descriptors are scored, so lenses are evidence of difficulty, not proof it has gone. Give your wear time ceiling, your intolerance days, and what lenses never fix.

My corrected vision is good on the chart. Can I still claim ADP?

Yes. A clinic figure is a best case measurement in ideal conditions. State it honestly, then describe wear time, glare, fluctuation and the hours without lenses, because ADP is scored on function across a period.

I have had corneal cross-linking. Does that affect my ADP claim?

No. Cross-linking slows or stops progression rather than restoring vision, and NHS information states you will still need glasses or lenses afterwards. Say when you had it and how your vision has been since.

Which ADP activities does keratoconus usually score on?

Usually reading, planning and following a journey, and moving around, plus preparing food. Managing therapy is the one people most often leave blank, even though the lens routine, drops and appointments belong there.

How much is Adult Disability Payment worth for keratoconus?

It depends on points, not diagnosis. In 2026/27 daily living pays £76.70 or £114.60 a week and mobility pays £30.30 or £80.00, with 8 to 11 points giving standard and 12 or more giving enhanced.
