The choice of either LASIK or Implantable Collamer Lens( ICL) really boils down to answering the key questions of whether your corneas are thick enough for LASIK to be performed safely or if there is sufficient intra-ocular space to accommodate an ICL.
To be clear, both treatments can result in patients seeing haloes and glare at night though the risk may be relatively lower in ICL compared to LASIK when dealing with higher degrees of refractive error.
With regards to improving your night vision, both procedures have the potential to help you in that respect. What is important though is for your surgeon to perform a thorough eye assessment to exclude important eye conditions such as glaucoma, cataracts and retinal detachment that are known to be associated with highly myopic eyes and that may in themselves cause poor vision in low light.
