PIP for Keratoconus

Can you get PIP for keratoconus? Yes, when the distorted vision, glare and lens problems it causes limit what you can do on most days. PIP is never awarded for a diagnosis, so the claim does not turn on the word keratoconus or on how thin your cornea is. It turns on what you can and cannot see well enough to do.

Keratoconus is awkward to claim for, and the reason is specific. It is a condition where the aid usually works, but not all the time. Most people are not registered sight impaired, best-corrected vision on a clinic chart can look reasonable, and yet the practical day is full of hours where reading is impossible, screens are unusable and going out alone in the dark is not safe.

Which Activities Does Keratoconus Affect?

PIP scores twelve activities. Keratoconus reaches fewer of them than a condition like arthritis, but it can reach them hard. These are the ones to think about carefully.

Activity 8: Reading and understanding signs, symbols and words

This is usually the strongest activity for keratoconus. Distortion, ghosting and double images make sustained reading exhausting even when the letters are technically visible. Describe how long you can read before it becomes impossible, whether you need large print or magnification, whether you rely on screen readers or text-to-speech, and what happens when you cannot wear your lenses. Our page on Activity 8 explains how aids are treated here.

Activity 11: Planning and following journeys

Glare, halos around lights and poor contrast sensitivity make unfamiliar places and dark evenings genuinely difficult. If you cannot read signs or platform boards reliably, cannot drive at night, or need someone with you for unfamiliar routes, that belongs in Activity 11. Say plainly which journeys you avoid rather than only describing the ones you manage.

Activity 1: Preparing food

Safety is the key word. Chopping with a sharp knife, judging the edge of a hot pan and reading cooking instructions or use-by dates all depend on clear, stable vision. If you have cut or burned yourself, or you avoid cooking on lens-free days, that is exactly what Activity 1 is asking about.

Activity 12: Moving around

Less commonly relevant, but worth considering if glare, poor contrast or night vision make steps, kerbs and uneven ground hazardous, or if you need someone with you outdoors. Bear in mind this activity is about physical movement outdoors rather than about navigation, which sits under Activity 11.

Activities 3 and 4: Managing therapy, washing and bathing

Managing treatments can matter more than people expect. Inserting and removing scleral or rigid lenses, keeping a cleaning routine sterile, and managing drops after cross-linking all take time and sometimes help from another person. Washing and bathing can be affected where you cannot see well without lenses in and have to manage the bathroom with unaided vision.

The Corrected Vision Trap

The single most common reason a keratoconus claim reads weakly is that it describes vision at its best. Clinic measurements are taken with lenses in, in controlled lighting, for a few minutes. That number goes in your notes and it can make your sight look much better than your day feels.

PIP does not ask about your best moment. It asks whether you can complete each activity safely, to an acceptable standard, repeatedly and within a reasonable time, on more than half the days. For keratoconus that usually means writing about four specific things:

• Wearing time. How many hours can you actually tolerate your lenses before your eyes are too dry, gritty or sore to continue? What happens for the rest of the day?
• Lens-free days. Infections, abrasions, allergies and lost or damaged lenses all produce days with unaided vision. How often, and what can you not do on those days?
• Fluctuation. Vision that changes through the day, or between appointments, is characteristic of this condition. Prescriptions that keep changing are worth mentioning.
• Light conditions. Many people function reasonably in even indoor light and very badly in bright sun, at dusk, or under headlights.

Registration, and Why You Do Not Need It

Certification as sight impaired or severely sight impaired is powerful evidence when someone has it. Most people with keratoconus do not, because best-corrected vision with specialist lenses often sits above the thresholds even when unaided vision is poor.

That is not a barrier to claiming. PIP has no registration requirement and no visual acuity threshold. If you also have a broader visual impairment, our guide to PIP for sight loss covers registration categories and how they are treated. For keratoconus specifically, argue function rather than certificates.

Treatment Stages and What They Mean for a Claim

Keratoconus is usually managed in stages, and each has a different practical effect.

• Glasses and soft lenses. Often adequate early on. Claims at this stage tend to be weaker unless there are other conditions in the picture.
• Rigid gas permeable and scleral lenses. The stage most claimants are at. Vision can be good when the lenses are in and tolerated, which is exactly why wearing time and lens-free days need to be spelled out.
• Corneal cross-linking. Aims to halt progression rather than to restore sight, and it does not remove the existing distortion. Some people experience glare or halos afterwards. Do not let a completed procedure be read as a cure.
• Corneal transplant. Used in advanced disease. Vision often improves, but stabilising can take a long time and lenses are frequently still needed afterwards. If you are in that recovery period, describe the period you are actually in.

Evidence That Helps

Aim for evidence about function rather than about anatomy. A topography scan proves you have keratoconus, which is rarely the disputed point.

• A letter from your ophthalmologist or corneal clinic describing progression, treatments and, ideally, the practical effect on daily activities.
• A letter from your optometrist or contact lens practitioner about tolerance and realistic daily wearing time. This is the single most useful document for this condition and it is often the easiest to obtain.
• Records of infections, abrasions or lens complications, which evidence the days you cannot wear lenses.
• A short diary covering a few weeks, noting wearing hours and what you could not do outside them. Our guide to keeping a PIP diary explains the format.
• If you have other conditions as well, list them: our guides to claiming with multiple conditions and mental and physical conditions together cover how they combine.

Our PIP evidence checklist covers what carries weight generally, and what to write on your PIP form has worked examples per activity.

At the Assessment

Assessors record informal observations, and a person who arrives wearing well-fitted lenses, makes eye contact and reads a consent form can be described as having no significant visual difficulty. That description may be accurate for the twenty minutes you were observed and useless as a description of your week.

Say at the start how long you have had your lenses in that day and how long you can keep them in. If the assessment is by telephone, mention that you cannot see the assessor and that a phone screen is one of the harder things for you to use. If you were asked to read anything, note how it actually went. Our guide to preparing for a PIP assessment covers the wider preparation.

If You Are Refused

Refusals for keratoconus very often rest on best-corrected acuity: a decision letter saying that with lenses you can see well enough for the activities. That is an arguable point rather than a final answer, because it ignores wearing time, tolerance and fluctuation, which is precisely what the reliability rules exist to capture.

You have one month from the date on the decision letter to request a Mandatory Reconsideration, and around two thirds of appeals that reach a tribunal succeed, so a refusal is a stage rather than an ending. Our guide to what to do when PIP is denied sets out the sequence.

Frequently Asked Questions

Can you get PIP for keratoconus?

Yes. PIP is not awarded for a diagnosis, it is awarded for the effects, so keratoconus can qualify when distorted vision, glare, poor night vision or lens intolerance limit activities such as reading, planning and following journeys, or preparing food safely on most days. Many people with keratoconus are not registered sight impaired and still score points.

Can you claim PIP for keratoconus if contact lenses correct your vision?

Yes. The test is whether you can do each activity safely, to an acceptable standard, repeatedly and in a reasonable time on more than half the days, using any aid you need. If you can only wear your lenses for part of the day, cannot tolerate them during flare-ups or infections, or your vision fluctuates through the day, describe what happens outside those good hours rather than at your best-corrected moment.

How much PIP could I get for keratoconus?

It depends entirely on how many activities are affected and how severely. Daily living pays £76.70 or £114.60 a week in 2026/27 and mobility pays £30.30 or £80.00, with 8 points needed for the standard rate of a component and 12 for the enhanced rate. Keratoconus most often scores on reading, journeys and food preparation.

Do I need to be registered sight impaired to claim?

No. Registration as sight impaired or severely sight impaired is strong evidence when you have it, but most people with keratoconus never reach that threshold and can still qualify. What matters is the functional effect on the twelve activities, not a certificate.

Which PIP activities does keratoconus usually affect?

Most commonly Activity 8 (reading and understanding signs, symbols and words), Activity 11 (planning and following journeys), and Activity 1 (preparing food) because of safety with knives and hot pans. Activity 12 (moving around) can also be affected where glare, poor contrast or night vision make unfamiliar surfaces hazardous.

Does having had cross-linking or a corneal transplant affect my claim?

Treatment history does not decide the claim; current function does. Cross-linking aims to stop progression rather than restore vision, and vision can take a long time to settle after a transplant. Describe how you see now, including any period of recovery, glare, halos or lens problems that followed the procedure.

What evidence helps a keratoconus claim?

Letters from your ophthalmologist or corneal clinic, your optometrist or contact lens practitioner (especially about tolerance and wearing time), and any hospital appointment records. Evidence that describes function is more useful than a topography scan alone, so ask for wording about what you can and cannot see and for how long you can wear your lenses.
