Will I need scleral lenses for the rest of my life?

It’s a fair thing to worry about

Learning a new daily routine is hard enough. Picturing it stretching out for the rest of your life can feel like too much. Many wearers say the same thing in the first months: they’re grateful for the vision, and quietly dreading the idea of “forever.”

So here’s the honest picture. For some people, scleral lenses are a long-term part of life. For others, they’re one stage. And for nearly everyone, “long term” doesn’t mean the same lens, the same fit, or the same routine forever.

Why the answer depends on your condition

A scleral lens doesn’t fix the eye underneath it. It vaults over the cornea and holds a layer of saline against it, and the lens surface does the focusing. That’s why it works so well for an irregular cornea, and also why the need for it usually lasts as long as the irregular shape does.

Most people who wear scleral lenses wear them for that reason. In an international survey of scleral lens fitters, 87% of the patients described were wearing them for corneal irregularity, 9% for ocular surface disease, and 4% for ordinary prescriptions.^[1]

Usually long term: keratoconus and other irregular corneas

Keratoconus, pellucid marginal degeneration, scarring, and corneas reshaped by surgery or injury don’t usually return to a regular shape. For these, a scleral lens is typically a long-term way of seeing well rather than a temporary fix.

That can be a good thing. In a study of 51 eyes with severe keratoconus that would otherwise have gone to transplant surgery, 40 were still wearing scleral lenses at their last visit, an average of about two and a half years later.^[2] For many people, long-term lens wear is what lets them avoid or delay surgery.

Treatment can change the course of keratoconus, but usually not the need for lenses. Corneal cross-linking is designed to stop the cornea getting steeper. In a randomized trial of 60 young people with progressive keratoconus, the disease progressed in 7% of eyes that had cross-linking, compared with 43% of eyes given standard care.^[4] The trial’s authors suggested that if that holds over longer follow-up, some young patients might avoid needing contact lenses later.^[4] That’s a hope for some, not a promise, and it applies mostly to catching keratoconus early. See scleral lenses vs cross-linking.

After a corneal transplant

A transplant can feel like the exit from lens wear, and sometimes it is. But a graft rarely heals into a perfectly regular curve. Small amounts of astigmatism afterward can be managed with glasses, while larger amounts may need contact lenses or more surgery.^[5] In a systematic review of 464 grafted eyes fitted with contact lenses, scleral lenses were the most common type, used in 61%.^[6] So a transplant can reduce, change, or occasionally end your need for lenses, depending on how the graft heals. See scleral lenses vs corneal transplant.

Dry eye and other surface conditions

When the lens is there to protect and soothe the surface of the eye, how long you need it depends on the condition behind it. Many of these conditions, such as severe dry eye, Sjögren’s, or ocular graft-versus-host disease, are long-lasting and managed rather than cured. Others can change with treatment. Your eye doctor is the only person who can tell you which applies to you, and whether there are steps that might reduce how much you depend on the lens.

“Forever” doesn’t mean one lens forever

Even when you need scleral lenses for many years, the lenses themselves change:

• Your eye can change. In a study of 157 keratoconus eyes that had worn scleral lenses successfully for at least a year, 14.6% lost some of their best vision with the lens during the study, all because the keratoconus progressed. Refits were the most common way problems were handled, making up 54% of interventions.^[3]
• Lenses wear out. In a review of 251 patients at one university hospital clinic, the average time between lens orders was 23.9 months, with a very wide range.^[7] See when to replace scleral lenses.
• Lens designs keep changing. A refit years from now may use a different design from the one you have today.

That’s also why follow-up visits matter even when everything feels fine. Regular exams are on the FDA’s list of contact lens safety basics.^[8] See how often to see your fitter.

What helps when “forever” feels heavy

Wearers who’ve been at it a long time tend to say the same things:

• It gets smaller. The routine that takes all your attention in month one usually becomes background, like brushing your teeth.
• Take it a stage at a time. You don’t have to decide about the rest of your life today. Get through the fitting, then the first months, then reassess with your fitter.
• Make it easier where you can. Emergency kits in your bag and car, a set place for your supplies, and a backup plan for bad days all take some of the weight off. See living with scleral lenses.
• Keep current glasses. The FDA recommends always having a backup pair with a current prescription.^[8] Knowing you have a fallback makes the long haul feel less fragile.

What to ask your eye doctor

• Is my condition likely to change, get worse, or stay the same?
• Is there a treatment, like cross-linking, that could change how long I need lenses?
• How well could glasses work for me now, as a backup?
• How often should my fit and my lenses be checked?
• If I ever want to stop wearing lenses, what would my options be?
