"In this retrospective study, we included data from 1936 eyes of 976 patients with stable systemic diseases who underwent LASIK surgery between January 2016 and June 2019. We defined nine different study arms including a control group, which consisted of 1951 patients and 3871 eyes and underwent also LASIK treatment during the same period. All eyes were matched based on age, gender, preoperative sphere and cylinder, treatment type, and eye side. All treatments were performed at private practices of “Care Vision Hamburg,” Germany, and in collaboration with the Ophthalmology Department of the Hospital Medical Center in Hamburg. All patient data were pseudonymized, and written consent was obtained from all patients before surgery. The study was conducted in compliance with the guidelines outlined in the Declaration of Helsinki approved from the local ethics committee (ID: 2021-1278). Additionally, the study was registered in the “German Clinical Trials Register” (trial number ID: DRKS00030317)."
