Bromelain prior to eye surgery?

I will be having upper and lower eye surgery in Korea next week. I am reading here about the benefits or arnica and bromelain. Currently I am only able to access Bromelain tablets (Kotase, 40 mg bromelain with Trypsin 1 mg). I read that bromelain can reduce post surgery swelling and bruising, yet may promote some degree of blood thinning. So my question, should I take this medication? What dosage (mg and times per day) and how many days pre and post surgery. Thanks for your help
