Ophthalmology:  Researchers compared adjustable sutures to non-adustable in 404 cases. They found that in primary surgery in adults with exotropia, there was a higher success rate with adjustable (80 vs 69%), but no difference in esotropia or vertical muscles. These single-surgeon studies are hard to apply to the real world, as his technique may very well be different than that of many surgeons, and therefore surgeons will continue to do what works best for them.
