Hi Kannsky, Greetings from the UK. Chemosis following lower lid blepharoplasty is pretty common and often to be expected especially following multilayer blepharoplasties due to all the surgical planes being disrupted. I usually reassure the patient by saying that it is typically not due to any problem with the surgery itself but due to normal healing reaction and inflammatory oedema just tracking under the conjunctiva causing it to elevate. As you say though, when the surface of the conjunctiva elevates above the tear film, this can irritate even more due to desiccation of the top of the conjunctival blisters which in itself cause irritation. Most surgeons would recommend intensive lubrication with a good long lasting ocular lubricant such as a hyaluronate based lubricant or a carbomer type lubricant. Although some surgeons do think that a topical steroid drop, there is not much evidence that it makes that much difference as the source of the inflammation itself isn't the ocular surface as such. So whilst you might give a topical steroid drop following squint, cataract or corneal graft surgery, most ophthalmologists nor oculoplastic surgeons would not routinely prescribe a topical steroid following their blepharoplasty surgery. Instead, most oculoplastic surgeons I think would recommend intensive ocular lubricants, sleeping upright, ice compresses only with the reassurance that chemises is pretty normal and self limiting.
