Yes. Initially your vision will be blurred, before beginning to recover during the first week. Depending on the underlying reason for PTK treatment ,it can sometimes take a few weeks for the vision to fully stabilise. You will need to wear a ‘bandage’ soft contact lens for at least one week to support the new epithelial cell layer as it heals. This lens stays in day and night (no need for you to remove it), before being removed by Mr Gore’s team in the clinic.
One advantage of modern laser technology is that the ablation profile is refractively neutral – this means that it is very unlikely that your spectacle or contact lens prescription will change. Similarly, if you don’t currently require spectacles, PTK is unlikely to change that.
