Managing large-angle exotropia (>70 PD) can be challenging with the various techniques available. In this case series, we present “True Muscle Transplantation"––a simple technique––to manage large-angle sensory exotropia as a possible alternative. Seven patients (four women and three men) of mean age 39.71 ± 17.38 years with sensory large-angle exotropia (>70 PD) underwent proposed surgery after detailed preoperative workup. The stump resected from MR was transplanted to LR and recessed. The mean preoperative deviation of 77.14 ± 4.52 PD base-in reduced to mean postoperative angle of 4.71 ± 4.42 PD at 6 months with good ocular alignment, no lateral incommittance, and no limitation of ductions in all patients. Stable results were maintained beyond 6 months. True Muscle Transplantation, therefore, has the potential of being a possible alternative.
