Living with keratoconus: everyday challenges and care

Keratoconus makes the cornea, the clear front surface of the eye, thinner and more irregular in shape. Light may not focus clearly, causing blur, ghosting, glare or halos. The two eyes can be affected differently.

Glasses can help when the irregularity is mild. Corneal RGP, hybrid, scleral or selected soft contact lens designs may help when glasses no longer provide adequate vision. The right choice depends on vision, fit, comfort and eye health. Our contact lens comparison explains the main options.

Cross-linking has a different purpose: it aims to slow or halt progression. It is performed by an ophthalmologist and does not remove the need for ongoing monitoring or necessarily replace glasses or lenses. Our keratoconus treatment guide explains the broader treatment pathway. ¹

Before inserting your lenses, vision may be less clear because you are not wearing your usual correction. This does not mean that everyone’s keratoconus is worse in the morning, or that a change should simply be waited out.

Allow enough time for the lens routine you have been taught. Wash and dry your hands, check your lenses for damage and use the prescribed products. For scleral lenses, fill the bowl with the sterile, preservative-free saline recommended by your optometrist. Saline fills the lens; it does not replace cleaning and disinfection. ²

Follow any individual advice about when to insert your lenses. If morning blur is new, persistent or noticeably different from your usual pattern, arrange a review rather than assuming it is normal.

Screen use can contribute to dryness and eye strain, particularly when you blink less or spend long periods concentrating. Take regular short breaks, look away into the distance and remember to blink fully. Enlarge text and adjust brightness, contrast and lighting to reduce glare. ³

Try both light and dark display settings and use the one that is easier for you to read. Dark mode is a preference, not a keratoconus treatment. If symptoms recur despite adjustments, your prescription, lens fit or ocular surface may need review.

For work or study, explain the specific task that is difficult. Larger text, accessible digital documents, seating away from glare or flexibility for lens care may help. Practical requests are often easier for others to understand than simply saying your vision is poor.

Avoid rubbing your eyes, and ask for help if they are regularly itchy. Research has found an association between eye rubbing and keratoconus, including a review involving CERA and University of Melbourne researchers. This does not mean rubbing alone caused your condition, or that every person with keratoconus has an allergy. ^{4, 5}

Tell your optometrist about itch, redness or allergy symptoms so the cause can be assessed and suitable treatment discussed. Ask which drops can be used with your lenses. Do not assume that a product bought for red eyes is appropriate for ongoing use.

A lens should provide useful vision and a healthy fit, as well as comfort. Recurring fogging, reduced wearing time or repeated redness deserve attention. Keep a note of when symptoms occur and what you are doing so your optometrist can assess the pattern.

If you have been taught to remove and refill a scleral lens, use clean hands and fresh sterile, preservative-free saline. Frequent refilling should not become a substitute for checking a recurring problem. Our scleral fitting and fees page explains the assessment process; individual care instructions remain part of your fitting. ²

Follow your prescribed wearing schedule. Clean and disinfect lenses with the recommended system, keep them away from tap water, and remove them before showering or swimming. Do not sleep in your keratoconus contact lenses unless specifically directed by your treating clinician. ⁶

If glare or ghosting makes driving difficult, discuss it at review. Do not drive when you cannot see safely; arrange another way home if necessary. Sunglasses can help with outdoor glare, but dark lenses are not a solution for night driving.

Progression is generally more likely in younger people, but keratoconus can continue changing beyond age 30. There is no fixed age at which everyone becomes stable. Feeling comfortable in lenses does not confirm that the cornea is unchanged. ^{7, 8}

Your review schedule should reflect your age, previous scans, treatment history and risk of progression. Corneal topography and tomography help assess shape and thickness over time. Keep the review schedule recommended for you and contact the practice sooner if vision changes.

If you are unsure what your tests mean, our symptoms and diagnosis guide explains how findings are assessed together. Regular monitoring remains important after cross-linking.

Keratoconus can be hard to explain because your eyes may look normal and your ability to see can change with the task, lighting or whether you are wearing lenses. Family members may not realise why glasses are helpful for one person but insufficient for another.

You could say: “The front surface of my eye is irregular, so things can look doubled or smeared rather than simply out of focus. My lenses help, but some situations are still harder.”

Tell people what support would help, such as reading small text, arranging transport when vision is poor, or allowing time for lens care. If worry about vision is affecting sleep, work or daily life, speak with your care team or GP. Support and realistic explanations are part of living well with a long-term eye condition. ⁹

Remove your contact lens and seek prompt advice for pain, increasing redness, light sensitivity or reduced vision. Sudden marked blur, new cloudiness of the cornea or a painful eye needs urgent assessment. Do not wait for a routine review or assume that every new symptom is keratoconus. ^{1, 6}

If the practice is closed and symptoms are sudden or severe, seek an urgent eye-care service or emergency department.

Tell us what is getting in the way of your day, not just how clearly you can read the chart. At Vision Camberwell Optometrists, we assess keratoconus, monitor corneal changes and fit contact lenses around your vision and practical needs.
