PRK | Innova ocular
This technique is performed on the surface of the cornea. It involves separating the corneal epithelium, the most superficial layer of the cornea. A special alcohol solution is used to clean the outermost part of the eye in order to work with the laser on a stable area; an Excimer laser can then be applied to the clean corneal bed.
The operation takes approximately 10 to 15 minutes and, as with Lasik, is performed under topical anaesthesia (eye drops). Once the effects of the anaesthetic have worn off, the patient may experience some discomfort for the first few days.
When a surface technique is used, recovery will be gradual; it is possible to return to normal life one week after the operation.
