Private Keratoconus Surgery Abroad Avoiding NHS Waiting Times
Keratoconus is one of the progressive dystrophies of the cornea, caused by inborn metabolic disorders. It is believed that abnormal collagen cross-link structure of the corneal stroma is the reason, which leads to thinning of the stroma and corneal distension, but peripheral zones are retained. Keratoconus usually manifests itself in the second or third decade of life. By definition, that applies to both eyes and the degree of development is usually different. Some cases of unilateral cone are treated with treatment abroad for cheaper than in the UK, as a state of different lesion advancement. The disease is progressive and most frequently changes are progressing by leaps and bounds, after which there may occur differently long lasting periods of stability. Mental crises, hormonal changes, stress may contribute to disease progression. In over 55 –year old patients, development of changes is usually stopped. Keratoconus is more common in general diseases like Down’s syndrome, Turner, Ehlers-Danlos syndrome, Marfan syndrome in atopic diseases, osteoporosis imperfecta, mitral valve prolapse and ocular disorders such as vernal keratoconjunctivitis, anirydia, Leber’s congenital blindness, pigmentary degeneration of retina , ectopia lentis.
Keratoconus correction with glasses:
It is used in the initial stages of the cone development, where the astigmatism is not large and regular enough. It is also effective when the cone is located far away from the optical centre.
Further development of the disease necessitates contact lenses or surgical treatment abroad.
Keratoconus soft lenses correction with toric soft lenses:
Theoretically possible, but for the high susceptibility and the tendency to surface projection of irregularities, this method usually does not produce satisfactory results.
Keratoconus correction with hybrid lenses and duo systems
In case of highly irregular corneas in over- sensitive to the presence of a foreign body in the eye or in the case of “weak” corneal epithelium, recurrent erosions, and hybrid lens can be selected or so-called this treatment abroad is much cheaper than in the UK. Duo-systems (two corrective hard lenses and soft carrier – protective). This solution is seemingly ideal, as it combines the convenience of carrying and good optical correction, but often leads to a decrease of mobility of the lens and dangerous cornea hypoxia leading to vascular neoplasia within cornea. This problem is even greater as it applies to people who are expected to undergo penetrating kerato-plastics treatment abroad. For these reasons, the solution should be a last resort. Slightly fewer risks have duo -systems applied temporarily only when we observe periodic intolerance to hard lens. Correction with hard lenses is the most popular. Full ranges of spherical lenses, a spherical -curve, specially designed for the correction of the cone are applied. Initially flat lens were fitted so as to squeeze the cone summit. Today there are alternatives in the form of ClearKone hybrid lenses, which have a rigid part that protects the corneal epithelium, but due to the soft part of the lens and tendency to suction, they have limited application. Fitting without touching the top of the cone, which is used for maximum protection of the cone, also cannot be widely applied because of the minimal improvement in visual acuity and too little mobility of the lens with a tendency to aggregate within the top of product metabolism taking place during hypoxia (hypoxia). That additionally worsens the condition of the already affected cornea. Contour three-point fitting is now the most recommended, maximally parallel to Keratoconus surgery. It requires the use of a variety of lenses from different manufacturers, often individually modified for a given case. It is very desirable to use of topography of the cornea, which not only speeds up the application of lenses, but allows to select the most suitable geometry of the contact lens.
Some Keratoconus treatments can be covered by NHS and can be refunded, if Keratoconus surgery is received in a private clinic abroad. Keratoconus abroad could be alternative you can afford.
It is possible to receive Keratoconus pre treatment and after treatment consultation in London.
