IN THIS VIDEO I PROVIDE A BRIEF EXPLANATION OF KERATOCONUS AND HOW WE TREAT IT

Everything you need to know about keratoconus

IN THESE TOGGLES YOU WILL FIND THE DETAILS YOU ARE LOOKING FOR

Keratoconus is a degenerative non-inflammatory disease of the cornea that causes it to gradually thin and bulge into a cone-like shape. Since the cornea is the primary focusing lens of the eye, any distortions in it lead to a distorted image projected onto the retina.

As the disease progresses, the cone becomes more pronounced, causing your vision to becomes more blurred and distorted.

Patients with keratoconus are usually very short-sighted and have severe astigmatism.

Keratoconus symptoms and lifestyle impacts

The early symptoms of keratoconus could be a continuous change in refraction (that is, a need to change glasses often). Some patients experience visual disturbance, such as seeing double, halos, glare, ghosting, or indistinct edge of objects. Nighttime driving, in particular, becomes more difficult with the progression of the disease.

The cause of keratoconus is not entirely understood, but it has been proven that a combination of genetic and environmental factors play a role.

Keratoconus can be triggered by environmental factors that cause you to repeatedly rub your eyes, weakening the collagen layers of the cornea and causing it to lose its shape.

At the Eye Clinic London, we know that the key to successful treatment is to deliver bespoke treatment based on each case. Hence, we will thoroughly assess your eyes and discuss your best options with you.

An examination will comprise of the following tests:

  • Refraction (spectacle test)
  • Ocular examination
  • A dilated fundus examination to check the health of the eye and retina
  • A scan to measure the amount of regular and irregular corneal astigmatism

We have various options depending on your unique case. These include:

  • Customised contact lenses
  • Corneal rings/implants (intracorneal rings/segments or corneal inlays)
  • Intraocular lens implantation
  • Various types of corneal transplantation
  • Topoguided laser vision correction

We are one of the very few centres in the world to perform a combination of various treatments.

The principle is to give you a complete treatment package of therapies that will strengthen your cornea and stabilise your keratoconus and at the same time, correct your vision.

Corneal cross-linking (CXL)

Corneal cross-linking a surgical procedure aimed at:

  • Patients with keratoconus, which is a congenital corneal disease. It starts in early childhood and progresses quickly to result in distortion of the standard corneal shape and curvature
  • Patients with corneal ectasia which is very similar to keratoconus but occurs after corneal refractive surgery such as LASIK, LASEK or SMILE where the cornea has become very weak

What does the procedure involve?

I apply one drop of riboflavin on the eye every 5 minutes for 30 minutes, and then the cornea is illuminated with UV-A light for approx.10 – 30 minutes (depending on the cross-linker used). The riboflavin forms bonds on the stromal layer of the cornea. We cover the eye with a bandage contact lens which is removed 5 to 7 days after the procedure. The cornea will be examined and scanned at frequent intervals to monitor for its stability.

I occasionally offer other types of cornea cross linking like Epi-on CXL. This is where we loosen your epithelium with eye drops or a sponge before putting in the eyedrops.

Corneal ring implants (Intracorneal Ring Segments ICRS)

Corneal implants are crescent-shaped rings that we place in the periphery of the cornea. They affect refraction in the eye by physically changing the shape of the cornea, flattening the front of the eye, and so correcting the irregular corneal shape.

What does the procedure involve?

We undertake the procedure under local anaesthesia. We make an incision in the cornea and create channels in it by using a femtosecond laser to ensure high precision. We then introduce one to two corneal implant segments is introduced into the channel. We offer various implants with a range of implant thicknesses for different degrees of correction.

Corneal rings are designed to remain permanently in the eye, yet we can also remove or replace them if needed.

Corneal grafts

With early detection, corneal cross linking with or without corneal rings implants will be sufficient to control keratoconus. However, if the disease is aggressive, progressive, or advanced then corneal transplant (corneal grafting) will be the only solution. In the most majority of keratoconus cases, partial thickness corneal transplant which is called Deep Anterior Lamellar Keratoplasty (DALK) would be sufficient. But if there is damage to the lining of the cornea then we can perform full-thickness corneal graft. Once the corneal graft is taken well and is stable then i could discuss with you various methods to improve the vision further. For example, you could benefit from laser / phototherapeutic keratoplasty (PTK), or topography-guided laser refractive surgery, or some type of intraocular lens implants such as Implantable contact / collamer lenses (ICL).
