To explore the lived experiences of patients undergoing acellular porcine corneal stroma (APCS) transplantation, a descriptive, qualitative design was performed. A purposive sample of 13 patients who underwent APCS transplantation to treat progressive infectious keratitis were enrolled in the semi-structured, open-ended interviews. The taped and transcribed interviews were analyzed using a thematic analysis approach. Alterations in the transparency of APCS grafts were accompanied by a gradual improved visual acuity (before surgery: 1.38± 0.91 logMAR; 3mo postoperatively: 0.40±0.24 logMAR, respectively). Accordingly, in terms of lived experiences, the patients generally reported “negative” experiences before the operation and during the early postoperative period, but this was greatly improved 3mo after surgery. Four main themes were derived: anxiety and fear, stigma, lifestyle change, and gratitude and insights. Conclusively, health care professionals should provide holistic care for patients, proactively promoting patients’ physical and mental health.
