Keratoconus sufferers can take comfort in the new trials that have found that cross-linking helps keratoconus. Affecting one person in every thousand, this degenerative disease in the eye causes the part of the eye known as the cornea to change its shape from a cone into a curve. This exciting new procedure has been shown to stop that regression.
The disorder affects the patients vision by not only causing distortion of the eyes by streaks and blurring, but also causes multiple imagery and sensitivity to light. It is usually during the early adolescent years that the condition is first noticed but it will typically worsen in patients older years of twenty and thirty.
The disorder can affect either eye, but if both eyes are affected then this obviously has an detrimental effect on the patients ability to drive a vehicle or read. For the majority of cases special corrective contact lenses or corneal ring segments are enough to correct the problem and allow for normal everyday functions, but sometimes the condition worsens and this requires surgery.
But new breakthroughs in technology have allowed optimism in the form of Corneal Collagen Cross-linking which has been shown to slow and even stop the advance of this incapacitating condition.
The treatment uses Riboflavin and UVA light to form new, strong bonds with the collagen strands in the corneal layer known as the stroma. After consultation, the procedure is performed under topical anaesthesia. The surface of the cornea is partially gently scratched. This has the same sensation as a foreign body inside the eye and will make the eye a little red. Drops of the Riboflavin solution is applied painlessly into the eye and is then activated by the UVA lighting beamed onto the cornea.
Patients have reported that the hour long operation was very positive and results were pleasing. Afterwards the patient is only required to wear a special eye pad and use antibiotic cream overnight as the corneal surface heals extremely rapidly. Self-administered pain relief can be used for the first 1-2 days as the eye may be a little uncomfortable.
Studies have all shown that cross-linking helps keratoconus and that it halts the decline of the cornea. With this positive news, corneal transplantation surgery might become a thing of the past.
