To answer your question, first we need to figure out what is wrong with your night vision.
Some people get a phenomenon called night myopia when their myopia degree seem to increase at night, partly due to a combination of increased accommodation tone through the day, and also due to pupil dilation in the dark which will cause an increase in higher order aberration.
There are also rare cases whose colour vision is problematic due to inherited eye disease, and these cases may manifest with poorer night vision. Some may simply have dry eyes that worsen through the day after long hours staring at the computer screen, culminating in deterioration in their quality of vision at night. There may even be early lens changes (cataract) that could cause a deterioration of night vision.
For my patients with a complaint like yours, I would usually make sure that I examine
1) their pupil size in the dark
2) the wavefront scans of their (a)cornea and (b) whole eye
3) A careful full eye check including colour vision, sometimes also the visual field.
A full refraction (including with relaxing eyedrops), detailed examination for dry eyes and of the lens and retina are my routine for all cases anyway.
So if the higher order / wavefront aberrations are higher than usual, I often would offer wavefront-guided LASIK or LASEK treatment (either cornea or total, depending on the age of the patient). SMILE does not treat higher order aberrations and is unlikely to incorporate wavefront-guided treatment in the foreseeable future, although in comparison, it tends not to induce wavefront aberrations compared to standard LASIK.
The current iteration of SMILE for correcting astigmatism is also not machine-guided, hence surgeon factor is important for correction of higher degrees of astigmatism.
The current ICL model (Staar Visian Evo) is significantly safer than previous models, as it now has a tiny hole right in the center to reduce possible complications. However, some patients notice a bit of night halos from this, although so far, none of my ICL patients found the halos problematic after a few weeks.
The choice between wavefront LASIK (surface ablation i.e. LASEK / epiLASIK/ PRK not recommended for high power like yours) vs ICL in your scenario will again depend on several factors. If your cornea thickness is irregular or insufficient to support safe wavefront-guided LASIK eyes (wavefront-guided treatment sacrifices more cornea tissue than standard LASIK), or if you suffer from dry eyes, ICL will be the choice treatment. However, there are also criteria for ICL such as the depth of your front of eye, the size of your cornea etc which you need to fulfill.
Hope you find a good solution for treatment of your refractive error. Best wishes!
