Usually, the Cornea has a hemisphere structure, alike a pearl. Sometimes, however, the shape of the cornea is not well built enough to confine this circular shape and therefore it, surges leading to the formation of cone alike appearance that is known as Keratoconus.
People suffering from keratoconus usually experience halos, double vision, and frequent changes in their vision. Keratoconus is a progressive disease, it is important that the condition is managed effectively under experts. Normally, the early-stage disease can be treated with spectacle.
However, as Keratoconus progresses, the corneal surface will undergo changes and this may necessitate the patient to use a rigid or hard contact lens that can help protect and strengthen the eye. If the lens does not yield the desired results, more invasive procedures may be needed as described below:
- Between 10% and 25% of cases of Keratoconus will progress to a point where vision correction is no longer possible, thinning of the cornea becomes excessive, or scarring as a result of contact lens wear causes problems of its own, and corneal transplantation also is known as Penetrating Keratoplasty becomes necessary. This being an invasive procedure, the acute recovery period can take four to six weeks and full post-operative vision stabilization often takes a year or more
Corneal Ring Segment Inserts:
- A recent surgical alternative to a corneal transplant is the insertion of intrastromal corneal ring segments, known by the trade name INTACS. The thin curve of polymethyl methacrylate is glide connecting the film of stroma on either side of the pupil ahead of incision closing while making an opening on edge of the cornea.
- In such cases, the eye tissue is not amended making it likely exchangeable and offers the advantage of being retracted.
Corneal Collagen Crosslinking With Riboflavin:
- A single-time lotion of riboflavin fluid is applied to the eye and is triggered by radiance accompanied by UV-A light for 30 minutes (estimated).
- The cornea’s power-driven muscle is maintained and redeemed by the formation of adjoining collagen fibre in the stromal layer of the cornea with the aid of riboflavin.
- You may also minimize the chances of Keratoconus by adopting Deep Anterior Lamellar Keratoplasty, often referred to as DALK.
- In a DALK transplant, the outlying epithelial tissue in the front line of the cornea and the stroma are replaced restoring the corneal endothelium surface of the cornea.
