Remember that every cross-linking procedure not only improves biomechanics, it also “disinfects” the cornea by directly killing all micro-organisms and by inhibiting cellular replication. This is why a cornea at the end of every CXL and PACK-CXL procedure is “sterile”. And by the way: office-based cataract surgery ve office-based intravitreal injections have been performed in many thousands of cases without increased infection risk.
