The fundamentals of laser surgery for myopia correction are heavily dependent on 2 factors – firstly the level of myopia, and secondly the thickness of your cornea. Conceptually, the higher our myopia, the more corneal tissue will be removed.
Even with today’s advanced technology, LASIK can correct up to -10.00 of myopia. Hence, if your myopia is more than -10.00, it is likely that after LASIK, you will have some residual myopia.
There are other options available which caters to individuals with myopia higher than what LASIK can correct. One option is Implantable Contact Lens. These lenses are customized to correct up to -18.00 of myopia.
