If you are asking whether refractive surgery can correct high myopia, then the short answer is yes.
There are various options, including LASIK, epiLASIK, and Implantable Collamer Lens (ICL) surgery. The absolute limits of laser surgery go up to around -11D (provided cornea is thick enough) and for ICL surgery go up to around -16D (provided there is enough space in the front of the eye).
However, not everyone with high myopia will necessarily get a good result from such surgery. In order to decide the best option and suitability of a particular person to undergo such surgery, a full assessment of spectacle power, general health of the eye, and specific eye measurements such as corneal thickness and depth of the anterior chamber of the eye need to be done.
I would suggest that if you are keen to explore surgical options to correct your myopia, to arrange an appointment with a doctor who performs such surgery, and have the necessary tests done. The doctor, with the necessary test reports, will advise you whether LASIK or other surgery is able to provide you with good spectacle free vision afterwards.
