ExPRESS shunt surgery: preferred glaucoma surgery in residency training?

It is important to equip future ophthalmic surgeons with appropriate surgical skills without compromising patient care. The ExPRESS implant surgery is very similar to trabeculectomy surgery in both efficacy and technique, but is less traumatic and may be prone to less postoperative hypotony and require less postoperative hypotensive medications. although affording a way to teach a novice surgeon the steps and technique of trabeculectomy and minimizing patient risk, ExPRESS implantation is a more expensive surgery that involves placing a foreign body in the eye. Further, needling an ExPRESS is a more technically challenging procedure than needling a trabeculectomy and more limited in its scope.
