Generally, you can go up to 3 mm away from your eyelid margin to treat wrinkles around your eye. In this case it will be beneficial to have eyeshields to protect your eyes. When you get really close to the eyelid margin you will put your eyelashes at risk. Even if the laser doesn't hit it directly, you can have the plume singe the eyelashes. There are some that think the eyelashes do not grow back as long.
My experience has been with Deep FX. This can tighten up your skin but may need multiple treatments to get the results that you would like. Traditional co2 lasers can tighten up your skin in one treatment but you will have a week or so downtime.
The other way to improve the wrinkles is to volumize the area. It can be done especially in the lower eyelid and upper cheek area to bring back the youth that you used to have. Instead of cutting tissue away you add the volume that made you look young long ago.
