INTACS inserts reshape the curvature of the cornea from within, without removing any corneal tissue. You cannot feel them, and they are no more visible than a contact lens.
Imagine your cornea as a tent with a curved top. If you push out the sides of the tent, the top flattens. Similarly, when INTACS inserts are placed in the sides of the cornea, they flatten the central cornea and so reshape the cornea towards a more natural curvature.
INTACS inserts change the curvature of your eye by adding ultra-thin ring segments. They can be removed entirely if necessary, returning your eyes to their preoperative condition.
Adding volume in the periphery of the cornea causes a flattening effect to reduce the curve of the cornea more centrally. This reduces the degree of myopia and astigmatism, so improving the level of vision that can be achieved without glasses or contact lenses.
Furthermore, by reducing the corneal curvature, INTACS increase the likelihood of being able to fit and tolerate contact lenses. It may even be possible to use soft contact lenses to achieve the best visual results.
If you have keratoconus but are contact lens intolerant, the goal of the INTACS procedure is to improve functional vision with contact lenses or glasses and in some cases without them.
The main difference is that the SK version is placed slightly closer to the centre of the cornea, with a diameter of 6mm. This gives a greater flattening effect on the cornea.
After the procedure
After the procedure, there may be a single small stitch in the cornea. If so, we will remove this after a few weeks.
We will give you drops to use after the procedure.
These will be:
- Antibiotic / anti-inflammatory drops for four weeks
- Lubricating artificial tear drops to use as required
We will arrange follow-up examinations and monitor you carefully after your procedure.
