Blurry vision shortly after surgery is very common. The swelling is often the result of edema in the cornea essentially creating a temporary "bad contact lens". Ointments can of course cause blurriness as well, especially the thicker ones often prescribed for use at nighttime. However these sources of blurriness almost always improve shortly after surgery, and your blurriness seems to be getting worse.
Dryness can lead to corneal injury and eventually corneal damage, so it would be highly recommended for you see an opthalmologist to evaluate for this condition. Chemosis is a swelling condition that can cause blurriness. There are specific eyedrops to use for this condition. Sometimes surgery, especially on the canthus, can cause differential pressure on the globe and a change in the refraction of the eyes (i.e. when bulging eyes are made less bulging by canthal surgery. Even eye pressure can change, especially when patients use the steroid drops commonly prescribed after eyelid surgery. All these conditions would warrant specific and different treatments.
Bottom line you should see an ophthalmologist.
