Chemosis, or inflammation of the conjunctiva, happens about 20% of the time, even to the best of surgeons. It is usually treated initially by the measures you have mentioned. When it persists, as yours has, use of steroid drops is the next treatment, unless you have some contraindication. If so, there are non-steroidal antiinflammatory drops that can be used.
Occasionally, resection of persistently edematous (swollen) conjunctiva is necessary, but exceptionally rare. Although it is way too early to consider revision of the blepharoplasty, occasionally swelling or other factors (such as, in my own case, wearing a surgical mask that pulled the eyelid down for a period of time) can contribute to the continued irritation. Elimination of the instigating problem and occasionally massage of persistent edema can also lead to improvement.
