Intacs for Keratoconus and Kerectasia
Intrastromal Corneal Ring Segments
For patients with Keratoconus Intacs may be an option to correct astigmatism. Intacs are small, clear, crescent-shaped pieces of plastic polymer that are inserted into the cornea through a tiny incision. The pieces of plastic alter the shape of the cornea, thereby correcting the refractive error.
Since Intacs are inserted in the outer edge of the cornea, the centre of the cornea remains untouched. The advantage of Intacs is that they can be surgically removed or replaced by the surgeon at our St Helens practice if necessary. When Intacs are removed, the cornea returns to its pre-operative state.
Intacs cannot be used to correct higher levels of myopia or astigmatism. Some patients with Intacs experience a feeling of discomfort in the eye, while others can experience halos, difficulty with night vision, or an increase in astigmatism.
Please contact our clinic in St. Helens for more information about Intacs.
