London’s best treatment for Keratoconus

Keratoconus is a progressive eye condition that affects the development of your cornea (the outer layer of your eyes). Rather than your eye growing in a normal sphere shape, those with Keratoconus develop a cone-shaped cornea that progressively thins, causing a bulge to form on the eye.
 
This can make it very difficult for the eyes to focus. People who have keratoconus may experience blurry vision, headaches, inflammation in their cornea, frequent changes with their prescription glasses, glares or halos around lights and increased sensitivity to light.
 
We can provide you with our cross-linking treatment which is the most effective surgical treatment to manage your keratoconus symptoms with our cornea specialist.

Understanding your Keratoconus

When you arrive for a private consultation you will meet our friendly technician team who will guide you through some eye assessments to measure the thickness of your cornea and check the general health of your eyes.
Our eye assessments take around 1 hour which will inform your specialist of any cornea changes you have experienced and at what progression this may change in the future.
 
Our cornea specialist will carry out a corneal typography which measures the curve of your cornea to work out how much astigmatism (impaired eyesight) you have.
 
They will also measure the thickness of your cornea and If you have already been using keratoconus glasses or hard contact lenses to help correct your sight, it is most likely that you will be suitable for our cross-linking treatment to strengthen the corneal tissue.

Kerataconus treatment and cross-linking surgery

The initial treatment for Keratoconus is glasses. However, if the condition worsens, your opticians may suggest hard contact lenses to help correct your sight.
These lenses tend to be thicker and heavier than the soft kind and can also cause your vision to be distorted when you are looking through the edge of the lens.
 
Despite this, they provide a more even shape to your cornea, which helps improve your ability to focus.
 
If you are prescribed lenses, you may find that you have to change your glasses frequently. This is because the condition causes your cornea to be thinner and more flexible.

What is minimally invasive corneal cross-linking surgery?

Our specialists may consider corneal cross-linking as the best treatment to help improve your Keratoconus condition. Cross-linking surgery strengthens the collagen fibres in your cornea to prevent your keratoconus from worsening.
 
Our cornea surgeon uses special eye drops and ultraviolet A(UVA) light to help the damaged tissue in your cornea grow stronger.
 
This procedure stops the bulge of your eye from getting any worse as it adds special bonds that work like support beams to help the cornea strengthen.

Eliminating invasive surgeries

Cross-linking is an early surgical intervention which decreases the chance of needing invasive corneal surgeries in the future to prevent the eye from being at risk of blindness.

 

Keratoconus Glasses and Contact Lenses are used to help you see once your keratoconus has affected your vision. However, keratoconus glasses and contact lenses do not prevent the condition of keratoconus from getting worse.

A minimally invasive treatment

Cross-linking is a minimally invasive surgery which means your eye health is better protected against other future corneal procedures which require larger incisions.

 

Invasive surgeries can cause more complications with a longer recovery period whereas a minimally invasive surgery is easier and safer with a shorter recovery period.

Long term improvement

Your natural vision will be better protected. Keratoconus is a condition that worsens overtime and can cause a risk of blindness in the future.

 

You may achieve a visual improvement in your sight, although visual improvements are not the success of corneal cross-linking surgery.

Cornea transplant at My-iClinic

A cornea transplant (often known as Keratoplasty or a corneal graft) is a surgery we offer to protect the eyes from severe cases of progressive Keratoconus.
 
If your case of keratoconus worsens, it is likely that you will become intolerant to visual aids such as: glasses and/or contact lenses.
 
Our cornea specialist will be able to assess whether a corneal transplant will be a suitable treatment and will remove the damaged area of your cornea, replacing this with donor tissue.
 
A corneal transplant can significantly reduce the risk of vision loss and improve the health of your eyes for improving vision.

Managing Keratoconus! From Cross-Linking to Contact Lenses

Keratoconus changes the cornea’s shape, causing ghosting and blur but with the right plan we can stabilise the cornea and optimise vision. Use the table below to compare options by stage: when to consider cross-linking, which contact lenses work best, where rings or surface smoothing fit, and when graft surgery is considered. It also outlines key tests, follow-up timing, and red-flag symptoms that need urgent review.

Keratoconus Treatments & Follow-Up at a Glance

Compare stages, goals, tests, optical options, procedures, follow-up and when it’s urgent.

Stage / Scenario Treatment Goals Key Tests Optical Options In-Clinic Procedures Follow-Up Notes / Risks
Suspected / Early (no documented progression) Confirm diagnosis, optimise vision, monitor for change Topography/tomography, pachymetry, refraction, family/eye-rub history Glasses; soft KC designs; consider RGP/hybrid if ghosting — (no procedure if stable) 6–12 monthly with repeat maps Treat allergy; avoid eye rubbing; educate on red flags
Progressive Keratoconus (documented change) Stabilise cornea; preserve vision; prevent scarring Serial topography/tomography (Kmax, TCT), refraction change, corneal thickness Temporary glasses/contacts until stable post-procedure Corneal Cross-Linking (CXL) – epi-off or transepithelial (case dependent) Post-CXL: 1 wk, 1 mo, 3–6 mo, then 6–12 monthly Transient haze/discomfort common; most eyes stabilise after CXL
Post-CXL (stable) — Vision Optimisation Maximise clarity & comfort for daily tasks Over-refraction, topography, tear film evaluation Scleral lenses (high comfort), RGP/hybrid, custom soft KC lenses Select cases: Intrastromal Corneal Ring Segments (ICRS) to regularise cornea Lens checks 1–3 mo after fit; 6–12 monthly thereafter ICRS may reduce irregularity and lens dependence; not for very thin/scarred corneas
Irregular Surface with Adequate Thickness Smooth corneal optics in carefully selected cases Topography-guided planning, epithelial mapping, pachymetry — (spectacles/CLs usually still needed) Topography-guided PRK ± simultaneous CXL (“Athens protocol” in select eyes) Close review for haze; staged approach often preferred Niche indication; careful case selection and counselling essential
Advanced KC / Central Scarring or Extreme Thinning Restore corneal clarity/shape when lenses no longer viable OCT, pachymetry, endothelial status, contact lens tolerance Trial scleral lenses if possible while planning surgery DALK (lamellar) preferred if endothelium healthy; PK if full-thickness needed Frequent post-op initially; suture plan over months; lifelong annuals Graft rejection (PK>DALK), astigmatism, suture-related issues; excellent clarity when successful
Contact Lens Intolerance / Dry Eye Overlap Improve comfort & wear time; protect surface Tear film tests, meibomian assessment, surface staining Refit to mini-scleral/scleral; PF lubricants; lid heat/massage; consider punctal plugs Thermal pulsation/IPL for MGD; treat allergy/inflammation 4–8 weeks to stabilise; then 6–12 monthly Comfort drives success; address lids/allergy to prevent rubbing
Paediatric / Rapid Progression Early stabilisation to protect lifetime vision Frequent tomography, allergy/atopy work-up, compliance review Temporary optical correction as needed Prompt CXL (lower threshold); counselling for rub control 1–3 monthly early; widen if stable Higher progression risk; parental engagement crucial
Acute Corneal Hydrops (sudden pain & white cornea) Relieve symptoms; speed resolution; prevent scarring Slit-lamp, AS-OCT; rule out infection Bandage contact lens; hypertonic saline; cycloplegic for comfort Anterior chamber gas/air injection (select); manage IOP Urgent same-day; frequent follow-up until resolved May scar/flatten cornea; later grafting sometimes needed
Guidance is illustrative. Suitability for CXL, rings, surface treatments or grafts depends on detailed imaging and corneal thickness. Your My-iClinic specialist will tailor the plan and monitoring.

Our 10 Most Important FAQs For Keratoconus

Thinking about Keratoconus ? It’s natural to have questions about what it can do for you. From vision improvements to advanced safety features, here are the key benefits and facts that will help you understand why more people than ever are choosing laser vision correction.

If you suffer from Keratoconus it means there is a lack of collagen in your cornea which causes your eye to abnormally change into the shape of a cone. Keratoconus is a progressive eye condition and overtime can cause extreme blurry vision (astigmatism), sensitivity to light and can, in some very progressive cases, lead to blindness.

There is not a definite cause of keratoconus but a combination of genetic and environmental factors may develop the condition. It is reported that 10-20% of people who have Keratoconus also have a parent with the same condition yet in other cases, Keratoconus can develop from chronic eye-rubbing, Long screen time, Eye strain or inflammation of the eye.

Our cornea specialist may consider corneal cross-linking as the most suitable treatment to treat your keratoconus. Corneal cross-linking is where we use special eye drops and ultraviolet A (UVA) light to help the damaged tissue in your cornea grow stronger. This process stops the bulge of the eye getting any worse as it adds special bonds that work like support beams to help the cornea become stable overtime.

If you have keratoconus on two eyes, we would be able to treat both with our cross-linking procedure in two separate surgeries.

In very extreme cases Keratoconus can lead to permanent vision loss. Because Keratoconus is a progressive eye condition, not treating it could cause significant visual impairment in the future. If you have a very thin cornea, it is always best to get checked by our clinic to understand your treatment options. If you do not already use glasses or contact lenses to improve the condition of your keratoconus, our corneal specialist can offer cross-linking to slow or stop your cornea from abnormally growing and affecting your vision.

When you visit your local opticians you will be told of your keratoconus condition if it is identified. Keratoconus can cause:

  • Frequent changes in glasses prescription
  • Blurry, distorted or cloudy vision
  • Sensitivity to light
  • Glares, Halos and starbursts around lights
  • Headaches associated with eye pain
It is always best to visit your opticians first for an eye test. Once they have confirmed you have keratoconus our specialist can provide a suitable treatment calledcorneal-cross linkingto strengthen your corneal tissue. Whenbooking an appointment with us, we carry out comprehensive eye assessments which will determine the stage of your keratoconus and which treatment is best suited to help and manage your condition.

Whether your keratoconus is mild or severely progressing, you will need to see our Cornea specialist who can advise if our treatment is the best option for you. We only provide a surgical procedure called cross-linking and the suitability for this surgery depends on the condition of your keratoconus and if you may require cross-linking to stabilize the eyes.

Cross-linking is a minimally invasive treatment which means our specialist performs very minimal incisions to the eyes. A minimally invasive surgery is always recommended to prevent any further progression of your keratoconus condition and the likelihood of an invasive surgical procedure. For example, a corneal transplantation which requires removing the cornea completely.

We advise a 1 week recovery period after having your cross-linking surgery with us. Our corneal surgeon and nurse will also provide comprehensive aftercare instructions after your cross-linking procedure.

Glasses or contact lenses are used for people to correct the visual symptoms that occur from their Keratoconus condition whereas cross-linking is an early surgical intervention to help stop your Keratoconus from progressing even further. This surgery will not resolve blurry vision from keratoconus but will stop the blurring from getting worse in the future.
