Too Much Skin Removed After Blepharoplasty

The white dots are probably milia or tiny epithelial cysts. They can be lanced with a small needle. This is not uncommon after upper eyelid surgery or things like peels. A scar is inevitable with incisional surgery but is usually minimally perceptible with upper eyelids. However, the part of the scar that extends to the crow's feet area can produce more noticeable scar and also medially toward the nose can produce webbing if it goes to close to the inner corner of the eye. FInally, sometimes the scar itself is near invisible but what can be perceived is the transition between one type and color of skin on the lower eyelid and the type and color of skin of the upper eyelid, soft of like when a thick carpet of a certain thickness and color is joined to another carpet of different thickness and color.

The most important thing to consider when you think about too much skin being removed is whether you have enough skin for your eyelid and eyebrow to function separately. Usually, it requires at least 1 cm of skin from your blepharoplasty incision to your eyebrow and 1cm from that incision to your eyelid margin.
In some people, 1.5cm is needed from your eyelid crease to the bottom of your eyebrow. The visible line will get better with time. That's why I mentioned that it depends on when your procedure was completed.
The white dots are likely inclusion cysts which very easily happen in the eyelid. All you have to do with this is to unroof the cyst with a needle and express the contents. They may reoccur, which could require a small excision of the cyst. The web usually occurs in the middle part of your eye. This is a little more trickier to fix. Steroid injections help. More complex procedures can also alleviate the presence of this web.
