I saw a comment where they say the flap never heals but with PRK it heals and gets even stronger. I would like you explain that , please and thanks>.

With PRK the …
With PRK the surface is treated. The surface has a clear skin that is removed, so essentially a scratch occurs that has to heal. The optical surface is like the surface of a pond, with any change like a ripple that takes many weeks to smooth. Laser flaps are like the best of both; in almost all cases pristine in the center even by the next morning. Rare exceptions consult your doctor etc. Also the optics and accuracy in modern lasik are far superior to previous generations of laser treatment.

Finally, since its …
Finally, since its so much more precise and less volume less nerves are cut - there is less dryness risk and less weakening risk. Excellent patient selection and use of wavemap derived ablation for improved optics makes this a much more refined, safe, and precise option than conventional lasik still done today. Have your doctor review your risks.

The lasik flap …
The lasik flap using a keratome is unpredictably large and to some degree unpredictably deep.

The laser flap is precisely controlled diameter and thickness - it is just about the safety of PRK (barely thicker than the epithelium alone,with the convenience of lasik.

No longer are there rare blade flap related complications to worry about. The risk of a flap complication is reduced - its never say never, not zero, but becomes extremely rare.

Is this the latest in Lasik?, still a flat has to be created? what’s the difference with PRK ?
