there is always a risk in any kind of surgery including Lasik and ICL. I often recommend patients to only visit clinics with substantial experience of surgery. You can’t take chance when it comes to vital part of your body such as vision. Now since you already had a overcorrected lasik, i am not too sure if you can have another lasik on the same eye. You can however consult with reputed doctors, don’t ask newbie doctors. They can simply recommend you anything for money. Seriously, i have encountred this in past.

As far as ICL goes, it could be helpful as well, again its very important that you consult with a highly professional and experienced doctor before going ahead.

Always the best way out is wearing contact lenses. My wild guess with that eye irritation is basically since you overcorrected your vision, its causing discomfort without contacts. Did you do a recent eye exam or tried to change ur glasses? Maybe the glasses are not suitable for your eyes. Check this first before going for another lasik/ICL. I have been using contacts since last 10 years or so. I am now used to it totally.

Good luck. Let me know if you need help.
