Scar tissue after eye surgery not only have affects on the appearance of the patient, but also influences on the person's vision. Scaring is a common post-operative side effect of surgeries to treat glaucoma, retinal detachment and cataracts. In order to prevent scar tissue after eye surgery, you can consult ophthalmologist about drugs like polyvalent dendrimer glucosamines that could imitate the body's immune system to prevent eye interior scarring. Or you can do a post-op laser surgery to burn away scar tissue literally. Additionally, you can ask your surgeon to place silicon oil in the eye during the surgery to reduce scarring in the days immediately following the operation. These days are the most effective time to prevent scar formation. What is more, you should avoid rubbing your eye area for two months to reduce the risk of causing additional scarring. Last but not the least, you should select the eyelid surgery that covers makeup to hide scarring.
