What is arcuate keratotomy?
It is a technique used for the treatment of astigmatism. Corneas with astigmatism are characterized by having one plane more curved than the other, giving rise to an elliptical or oval shape.
To correct this refractive error, arcuate keratotomy is performed, which consists of making incisions in the most curved meridians of the cornea to flatten it and reduce the patient’s astigmatism.
The intervention is performed applying topical anaesthesia and sedation.
In which cases is it done?
Surgery is reserved for patients with very high astigmatism, or patients with astigmatism who have previously undergone a corneal transplant.
A complete ophthalmological review is recommended to verify that the patient may be a candidate for arcuate keratotomy. Once it has been decided that surgery will be performed, specific preoperative tests must be performed, such as corneal topography (see the previous corneal relief) and pachymetry (measure the thickness of the cornea).
The patient may still have a few diopters of astigmatism that can be corrected later with lasik surgery.

Risks of arcuate keratotomy
Any surgical intervention carries risks. To minimize them, it is recommended that arcuate keratotomy be performed by ophthalmologists specialized in refractive and corneal surgery.
