Eye doctors generally prefer ICL (Implantable Contact Lens) surgery, instead of LASIK for high grade myopia.
As the name suggests, ICL is where a soft contact lens is implanted in front of your eye’s natural lens behind the cornea, via a small cornea incision. Unlike LASIK, it doesn’t require any removal of corneal tissue.
LASIK is typically used to correct myopia of up to -14D (1400 degrees), while ICL can treat much higher degrees of myopia of up to -18D (-1800 degrees).
ICL carries the associated risks of having a foreign body in your eye, such as a slightly increased risk of infection etc. It’s also more expensive than LASIK.
Eye floaters do not affect the outcome of LASIK. However, LASIK is not a treatment for floaters.
Besides the severity of myopia, there are other factors to consider in determining the most appropriate treatment to correct myopia – this requires an eye examination and history.
I’d suggest going for a proper consultation with a LASIK surgeon to evaluate these factors, with the other main considerations being your corneal thickness and shape. He will then be able to advise on the best treatment modality.
