“…Both excimer and femtosecond lasers may, in theory, be regarded as potentially harmful due to the energy emitted during treatment. Possible mechanisms include mechanical trauma from shock waves, thermal effects, secondary ultraviolet radiation, and metabolic changes [ 13 , 14 ].…”

“…Various mechanisms may have a potential impact on the corneal endothelium during laser refractive procedures. Risks generated by an excimer laser include mechanical trauma from shock waves, oxidation, and thermal effects from UV light [ 13 , 14 ] that may harm fragile endothelial cells. Accumulated energy delivered in procedures involving both femtosecond and excimer lasers (FemtoLASIK) may contribute to even greater corneal endothelial cell damage [ 15 , 16 ].…”

Background: The aim of this review was to investigate the influence of various laser refractive surgery methods on the corneal endothelium in myopic patients. The role of the corneal endothelium in laser refractive surgery (LRS) is currently being addressed in the assessment of postoperative corneal edema risk. Methods: Changes in corneal endothelial cell density and morphology after LRS were evaluated based on a systematic review of current studies. The results of a literature search in the PubMed, Science Direct, Google Scholar, and the Web of Science databases, as well as a manual search, were selected for the final review according to the PRISMA 2020 flow diagram. Results: We included 24 prospective clinical trials in the review: surface ablation (twelve), LASIK and FemtoLASIK (two), femtosecond lenticule extraction (two), and comparable studies (eight). Endothelial cell density was determined by specular or in vivo confocal microscopy. In most studies, no statistically significant differences were found between preoperative and postoperative endothelial parameters. In nine studies, the changes were statistically significant, but no vision-threatening complications occurred, and no serious corneal complications developed in any eyes during the follow-up period. Conclusions: Based on collected data, laser keratorefractive surgery appears not to exert a significant effect on the corneal endothelium.
