Femtosecond laser (FSL) applications in corneal surgery have increased since its inception. Corneal surgery has undergone a tremendous transformation thanks to the introduction of FSL technology. This laser makes precise, three-dimensional incisions while causing minimal damage to surrounding tissue. This review updates and summarizes current and upcoming FSL applications in corneal surgery, current commercially available FSL, and its respective applications. Refractive surgery applications include laser in-situ keratomileusis flaps, refractive corneal lenticule extraction such as small incision lenticule extraction, astigmatic keratotomy, intracorneal ring segments tunnels for keratoconus including corneal allogenic intrastromal ring segments, and presbyopia treatments with intrastromal pockets for corneal inlays and intrastromal incisions (INTRACOR). Keratoplasty applications include penetrating keratoplasty trephination; superficial and deep anterior lamellar keratoplasty trephination, lamellar dissection, and tunnel creation; posterior lamellar keratoplasty donor and recipient preparation; Bowman layer transplantation donor, and recipient preparation; and stromal keratophakia. Other applications include conjunctival graft preparation in pterygium surgery, and keratopigmentation (corneal tattooing). FSL is a surgical instrument widely used in corneal surgery because it improves reproducibility and safety in many procedures.

Introduction: Femtosecond laser devices have been praised for their precision in corneal surgery; however, their performance in endothelial corneal graft surgery is still in development compared to the standard microkeratome technique. The purpose of this study is to describe the anatomical and functional differences in surgical outcomes between microkeratome (mk) and femtosecond laser (fs) assisted Descemet stripping automated endothelial keratoplasty (DSAEK). Methods: This is an analytic, observational, pilot study of patients who underwent mk-DSAEK or fs-DSAEK. The data were obtained from the clinical records and the institutional transplant registry with a focus on graft measurements, survival, transparency, visual acuity and was further analyzed. Results: A total of 37 participants were included in the study with 70.3% (n = 26) of them being female and 29.7% of them being male (n = 11). Of the 37 eyes, 23 (62.2%) of them underwent mk-DSAEK and 14 (37.8%) of them underwent fs-DSAEK. Optimized femtosecond laser parameters are reported. There was a statistically significant difference in donor graft thickness which was thinner in the fs-DSAEK group with a median of 110 mm interquartile range (IQR) (102.25–117.5) versus a median of 233 mm IQR (219–243.75) P = 0.00 in the mk-DSAEK group. There were no significant differences for other variables between techniques. Conclusion: Fs-DSAEK allowed significantly thinner graft obtention in comparison to mk-DSAEK; however, there were no significant differences between mk-DSAEK and fs-DSAEK in terms of transparency, graft survival, or visual acuity.
