What is Keratoconus?

Welcome to Precision Vision, your trusted destination for comprehensive eye care. Explore our insights on Keratoconus, a condition impacting the cornea, the eye’s crucial “window.” Our expert team at Precision Vision is dedicated to providing valuable information on this progressive degenerative disease.

Derived from the Greek words ‘kerato’ (cornea) and ‘konos’ (cone), Keratoconus affects approximately one in every 2000 individuals. This condition initiates during the critical ages of 10 to 25, often starting in one eye and progressively impacting the other. The cornea undergoes thinning and bulging, assuming a cone shape and compromising its stability, leading to distorted vision.

Although the exact cause remains unknown, studies suggest a hereditary connection, with a propensity to run in families. Chromosomal and connective tissue disorders are strongly associated with Keratoconus. Individuals with atopic conditions like eczema, asthma, and hay fever may be at an increased risk. The symptoms of these conditions, such as eye rubbing, can accelerate the progression of Keratoconus. Additionally, factors like trauma, poor-fitting contact lenses, and excessive eye contact can contribute to the severity of the disease.

What are the Symptoms of Keratoconus?

Welcome to Precision Vision – Your Leading Keratoconus Treatment Clinic on Harley Street

Keratoconus is a progressive eye condition that leads to an increase in corneal steeping, causing thinning of the cornea and resulting in complex high prescriptions with irregular corneal astigmatism. This condition can significantly impact lives, leading to blurred sight that often progresses to ghosting or monocular diplopia (double vision), difficulty seeing at night, sensitivity to light, fluctuations in prescription, and eventual unusability of glasses.

Symptoms in the early stages may include mildly blurred or distorted vision, increased sensitivity to light and glare, and eye redness or swelling. During this phase, glasses may be effective in correcting vision, and special hard contact lenses can assist in restoring proper focus for those who typically wear contacts.

As Keratoconus progresses, increased nearsightedness and difficulty finding glasses to correct prescriptions may occur. Sufferers may transition to hard, rigid, or gas permeable contact lenses, which can be costly, uncomfortable, and unsuitable for extended wear.

While the condition typically progresses slowly, in some cases, it can worsen quickly, manifesting in increased blurriness and distortion in vision. Left untreated, Keratoconus can stabilise after impairing vision significantly or continue progressing to the point where a corneal transplant becomes necessary.

Given the critical role of vision in daily life, addressing the root cause of these symptoms is crucial. Our UK clinic, conveniently located on Harley Street, offers a range of advanced treatments for Keratoconus.

Visual Rehabilitation

Keratoconus is a progressive degenerative disease that can affect both eyes causing the cornea to thin and become misshapen taking a conical shape. This causes complex prescriptions and if left untreated can lead to a corneal graft.

Precision vision offer total visual rehabilitation with treatments that halt the disease, makes contact lens wear more comfortable and corrects prescriptions, removing the dependency on visual aids.

Precision vision is one of the only clinics in the country to offer total visual rehabilitation for sufferers of Keratoconus by providing treatments to:

Halt the progression of the disease (Collagen Cross-Linking)
Make contact lens wear more comfortable (INTACS, Kerarings and Kerasoft lenses)
Correct the visual impairment caused by the disease (Implantable Contact Lenses, Lens Replacement & Piggyback lenses).

Suitability for this type of treatment will be determined at the consultation after comprehensive testing. Precision Vision’s leading surgeon, Dr. CT  Pillai is a highly respected corneal specialist who is present throughout every patient’s journey and designs a personalised treatment plan to achieve the visual goals of every individual.

Keratoconus FAQ's

What is Keratoconus?

Keratoconus is a common bilateral corneal disease that occurs in more than 1 in 2,000 people. Keratoconus is a non-inflammatory eye condition in which the normally round dome-shaped cornea progressively thins causing a cone-like bulge to develop. As a result, the eye develops a high complex prescription with astigmatism. Keratoconus is not visible to the naked eye but is apparent in an examination by an optometrist and scans.

What visual problems are experienced with Keratoconus?

The thinning and bulging of the cornea typically causes myopia (short sight) and astigmatisms. It can produce symptoms like blurring, ghosting, multiple images, sensitivity to light, difficulty seeing at night (halos and glare) and a fluctuating prescription. In advanced Keratoconus, scarring and loss of transparency of the clear cornea can cause permanent poor vision.

Does Keratoconus always deteriorate the vision?

Even though it is a degenerative disease there are patients where the disease naturally stabilises. This means that when a patient is over the age of 45 and have not required a corneal graft, their prescription is likely to have stabilised naturally. For those that the disease does not stabilise, it can mean the patient may need a corneal graft.

What treatments are available for Keratoconus?

There is no cure for keratoconus and it cannot be treated with medication. In the early stages, glasses or soft contact lenses can be used to correct the vision. As the cornea continues to thin and bulge, more complex and custom-made contact lenses such as hard, rigid or gas permeable contact lenses can be used to correct the vision. However, these can be difficult to fit or tolerate. Contact lenses do not make the Keratoconus better or worse but improve your vision whilst wearing them.

Where the keratoconus is progressing, or for those who are at high risk of it worsening, Collagen Cross-Linking can be used to stop or slow down the deterioration. Once the disease is stable there are several options that will be offered to patients to either make contact lenses wear more comfortable (Corneal implants) or completely correct the prescription (Implantable Contact Lenses and Clear Lens Exchange).

How does Collagen Cross Linking work?

Ultraviolet light and Riboflavin (Vitamin B2) drops are used to strengthen the cornea. The principal of Cross-linking is photopolymerisation. Riboflavin drops are administered to a de-epithelialised cornea and are activated by the UV light. The light-induced production of oxygen radicals leads to the development of strong chemical bonds between collagen fibres, thereby stiffening and strengthening the cornea.

Once Keratoconus is stable is there anything available to correct the prescription?

If your condition is stable, whether naturally or with Collagen Cross-Linking, there are Kerasoft lenses and treatments available to correct the prescription caused by the disease. Dependent on your age, Clear Lens Exchange or Implantable Contact Lens treatment can be performed to free you from glasses and contact lenses.

Is Cross Linking invasive?

It is a non-surgical procedure: there are no incisions or stitches. The procedure is extremely safe and straightforward and only needs to be carried out once to cause a permanent change.

Is Collagen Cross Linking safe?

The Riboflavin drops used are simply vitamin B12, commonly used in foods and is harmless. The UV light exposure throughout the procedure is less than or comparable to the exposure the eye experiences throughout a full day outdoors in the summer Additionally, the wavelength is such that it is absorbed effectively enough to protect the deeper layers of the eye, consequently posing no risk.

What are Corneal Implants?

These are Intrastromal Corneal Ring Segments (ICRS) like INTACS, Kerarings and Ferrara rings. They are clear, micro-thin, crescent-shaped devices that are inserted into the cornea to help flatten the corneal shape and thus correct some of the prescription.

Corneal implants are a treatment option for sufferers of mild to moderate Keratoconus that is quick and effective. They are safe, reversible and do not affect the central visual axis of the cornea.

Can your body reject Corneal Implants?

The Intrastromal Corneal Ring Segments are made of poly-methyl-methacrylate which is a biocompatible material and will not be rejected by the body. They are also removable and exchangeable so different rings can be used as the correction required changes.

Will people be able to see you have had surgery?

There is no change in the appearance of the eye after Collagen Cross-Linking treatment and Corneal Implants are extremely difficult to see without a microscope or getting very close.

Will you be able to wear glasses or contact lenses after Collagen Cross Linking treatment?

After surgery, your cornea will require time to settle and during this, your prescription will fluctuate. It is possible to be refitted for glasses or contact lenses after the vision has stabilised. If a patient wears Kerasoft lenses they will be able to wear contact lenses sooner (usually a few weeks after the procedure).
