Pulse panko bread crumbs in a food processor until finely ground. Transfer to a shallow dish.
Process one-third of the shrimp with mayonnaise, salt, pepper, and cayenne until finely chopped.
Add remaining shrimp and pulse until coarsely chopped. Scrape down the sides as needed.
Transfer shrimp mixture to a bowl and stir in scallions.
Form the mixture into four 3/4-inch-thick patties and dredge in the ground panko.
Heat oil in a nonstick skillet over medium heat. Cook patties until golden brown, about 3-5 minutes per side. Ensure they reach an internal temperature of 140°F.
Transfer cooked patties to a paper towel-lined plate to drain excess oil.
Assemble the burgers by spreading tartar sauce on the buns, adding a shrimp patty and a lettuce leaf. Serve immediately.
