[3] A study published in 2017 documented fewer conjunctival and eyelid swelling complications in the immediate postoperative period after MISS than after conventional strabismus surgery with long-term results being similar between both groups.
Instead of one large opening of the conjunctiva as is done in conventional strabismus surgery, several small cuts are placed where the main surgical steps, usually suturing, have to be performed.
MISS openings markedly reduce the frequency and severity of corneal complications like, for example, dry eye syndrome and dellen formation, and will allow wearing contact lenses earlier.
Long-term benefits are avoidance of an increase in redness of the visible conjunctiva and a decreased scarring of the perimuscular tissue, which will facilitate reoperations - if those should become necessary.
This was documented, for instance, in comparing 40 children; the group that had undergone the minimally invasive procedure, however, did show less swelling of the conjunctiva and the eyelids after surgery.
