What is Keratoconus?

Keratoconus is a slowly progressive condition in which the cornea, the clear round window at the front of eye, becomes weaker and bulges forward. The cornea gradually changes shape from a sphere (like a football) to a cone (like a rugby ball), resulting in distorted and reduced vision.

The change in shape reduces the quality of vision, as it alters the refractive properties of the cornea. A key feature of Keratoconus is a gradual progression in short-sightedness (myopia) and astigmatism. As the condition becomes more advanced and the astigmatism irregular, spectacles fail to compensate for this, resulting in blurred vision. Other symptoms of Keratoconus can be distorted vision, double or multiple images, and streaks or haloes around lights.

The cause of Keratoconus is not fully understood but the condition is considered to develop due to a combination of genetic and environmental factors. However, it is not thought of as an inherited condition. There is a good association with atopy and often patients also have allergic eye disease with itchiness and rubbing of the eyes.

Detection by your optician of rapidly progressive myopia and astigmatism can be a sign of Keratoconus and requires further investigations. These investigations are usually carried out by an ophthalmologist (eye doctor) who will carry out a detailed examination with a slit-lamp biomicroscope and corneal topography imaging. Corneal topography involves detailed scanning of the cornea, plotting of its shape and comparison to the expected normal.   

How Laser Vision Eye Centre Can Help


Importance of early diagnosis

Early diagnosis of the condition is key to maintaining good vision. In the early stages, the vision can be improved with glasses or contact lenses. As the condition progresses and the cone become more advanced, the astigmatism becomes irregular and rigid gas permeable (hard) contact lenses are required to improve the vision. As the condition tends to be progressive in nature, wearing glasses and contact lenses does not stop the underlying progression.

Corneal collagen-cross-linking

Corneal collagen cross-linking is the only treatment option that can stop progression of the condition; however, it does not reverse changes in the shape of the cornea or any visual loss that may have already developed. In September 2013, the National Institute of Clinical Excellence (NICE) recommended the use of epithelium-off collagen cross-linking for Keratoconus and keratectasia (Interventional procedures guidance IPG466).

In collagen cross-linking, riboflavin (B2) eye drops interact with UVA light to stimulate the formation of extra bonds (cross-links) between the collagen fibres of the cornea, thus increasing its rigidity and strength.

Collagen cross-linking can be combined with laser treatment; this combined procedure not only stops progression of the condition but can also improve the quality of the vision.

Corneal collagen cross-linking Xtra

Collagen cross-linking can also be carried out with the aid of laser treatment. At the beginning of the procedure a transepithelial phototherapeutic keratectomy (t-PTK) can be performed instead of the traditional mechanical epithelial removal. This approach, also referred to as the Cretan protocol, has been shown to have several advantages over standard cross-linking; patients achieve better vision, less astigmatism and a more regularly shaped cornea. 

Topography guided laser treatment

Topography guided advanced surface ablation can improve the vision in patients with Keratoconus.  The excimer laser treatment is customised to the shape of the cornea, resculpting the corneal surface, and making the cornea more like a sphere. This reduces the irregular astigmatism and aberrations, improving the quality of vision. 

Advanced surface ablation can be performed after corneal collagen cross-linking has been carried out or the two procedures can be combined. The combination of the 2 procedures improves the strength of the cornea and also the quality of vision. The combined treatment is often referred to as the Athens protocol for Keratoconus.

Intrastromal corneal ring segments

Intrastromal corneal ring segments are small circular implants that are placed within the cornea. Their placement is guided by the precise creation of corneal channels with the use of our Visumax femtosecond laser. Their size and positioning are matched to the shape of your cornea, flattening the steep areas and returning the conical cornea to a more normal shape. This results in a reduction in short-sightedness (myopia), astigmatism and aberrations, improving your quality of vision.   

Corneal transplantation

In advanced cases of Keratoconus, in which the above methods of visual correction are not applicable, the vision can be improved with corneal transplantation. With the increasing awareness of Keratoconus and its earlier detection, the requirement for transplantation should decrease in the future.

In corneal transplantation the weaker cornea is replaced by a healthy donor cornea, restoring the normal optical properties of the eye and improving vision. Transplantation can take the form of a full thickness corneal graft, known as penetrating keratoplasty, or a partial thickness corneal transplant, known as deep anterior lamellar keratoplasty (DALK).

No More Glasses!!!
Aris and the team at the Laser Vision Eye Centre have been amazing! I had my eyes done last weekend and the whole process was really well organised. They answered all my questions and made sure I knew exactly what would happen. My vision is perfect now and I don't need to wear glasses any more. Awesome!! 😀 I would definitely recommend Aris and the Laser Vision Eye Centre.

Fantastic... PRESBYOND laser procedure
Dr Aris gave me complete confidence in the procedure I was having. At all times I felt I was in very able hands. I choose to have PRESBYOND laser treatment as I lost my reading vision and I had to wear glasses all the time - and I absolutely hated it! With this treatment I am now 3 months after the procedure and can see with great ease and I am enjoying life with out glasses. We achieved better results than ever anticipated.

The ‘Gold Standard’ of laser eye surgery
Mr David Anderson is one of the leading Consultant Ophthalmologists which is why I chose him to perform my surgery. During the consultation I was very much assured that I was in good hands, but also having the ‘Gold Standard’ of laser eye surgery. It was explained that my best option was LASEK due to an eye infection rendering me contact lens intolerant. This also left me with a slightly reduced tear film... read more.

Excellent Care
I received excellent care throughout my experience at Laser Vision Eye Centre under the clinical leadership of Mr David Anderson. Everything was explained before and as the procedure was carried out. The waiting time for the procedure was considerably shorter than on the NHS and I even received a telephone call from the hospital the next day to check that all was well.

Life changing experience
I have been very impressed by the level of pre op information given enabling me to make a knowledgeable decision on how to proceed. Mr ANDERSON explained exactly what was going on throughout, which really helped me feel reassured and safe. Post op the aftercare has been amazing, staff even called on a Sunday to check how I was feeling. I would not hesitate to recommend this clinic to everyone.

LASIK Presbyond Bilateral Laser Surgery
I recently underwent LASIK Presbyond surgery at the Wessex Nuffield Hospital. The surgery was performed by David Anderson and Aris Konstantopoulos and their incredible colleagues. I am so pleased I chose David and his team to carry out the procedure as the attention to detail both before, during and after surgery has been exceptional. Look no further 👀 this is the A Team! I can now write this review without the need for glasses.

I have been thoroughly impressed
I have been thoroughly impressed with the level of care and professionalism that Aris and his team have shown at all stages in the process. The initial assessment, the procedure itself and then follow-up consultations. Although this was something that I approached with much trepidation I am really happy with the way that it ended up and the path that I followed.
