Managing Keratoconus With Contact Lenses

In simple words, keratoconus can be described as the thinning of cornea. As a result of subsequent thinning, the cornea tends to misshapen. The cornea gains the shape of a cone, which leads to vision loss. A person suffering from keratoconus has vision that is similar to looking through an ice cube.

Using contact lenses to deal with keratoconus
A mild case of keratoconus can be easily treated using contact lenses. Gas permeable contact lenses have been used to deal with keratoconus for quite some time now. These lenses are aimed at correcting the irregular shape of the cornea. They give the cornea a regular surface. This helps minimize the distortion that is caused by an irregular cornea.

There are several kinds of contact lenses that can be used to treat keratoconus. Soft contact lenses can also be used to correct the problem. However, rigid contact lenses better serve the purpose. These days, there are a number of specialized rigid contact lenses that can help deal with the problem successfully.

The latest in rigid contact lenses for keratoconus is the 'synergize hybrid contact lens'. This lens is rigid in the middle and softer towards the edges. This contact lens combines the benefits of both- soft lenses and rigid lenses. While the rigidity of the lens gives you a perfect fit, the soft lens features provide you unmatched comfort.

Here are some basic categories of contact lenses that can be used to treat this problem:

* Standard rigid lenses- These lenses are spherical in curvature and offer the best fitting out of all other contact lenses.
* Aspheric lenses- This contact lens aims to vault the apex of the come. It flattens from the centre towards the periphery.
* Tricurve lens - It is a soft lens that has a thicker center. The thick center of this contact lens creates rigidity to provide accurate vision.
* Piggyback lens system- It is a two lens system. This contact lens type comprises of a soft lens that covers the cornea. The center of this lens has a small gas perm lens.
* Computer assisted contact lenses- Certain laboratories offer customized contact lens that can help deal with the problem.

Finding the right contact lens
If you are looking forward to treat keratoconus with contact lenses then there are several options to choose from. But, there is no one size fits all solution to this problem. In fact, the characteristics of the eye differ from one individual to the other. Several lenses need to be tried before the practitioner can zero in on one particular option. Consult your eye specialist or practitioner and he will be able to help you find a contact lens that works best for you.
