An eye shape modification (ESM) system such as a scleral buckle featuring a band having a first end, a second end opposite the first end, and a first side and a fixation zone disposed on the first side of the band. The fixation zone is adapted to accept sutures and can be sutured to a scleral surface. The ESM system may also feature a closure system for closing the two ends of the band together. The ESM system may also feature a calibrated shortening mechanism allowing a calibrated reduction in circumference and diameter.
