In this review, we have summarized the intraoperative application and postoperative outcomes of FSL-assisted keratoplasties, including penetrating keratoplasty, anterior lamellar keratoplasty (ALK), deep ALK, Descemet stripping automated endothelial keratoplasty (EK), and Descemet membrane EK. Although FSL allows for the customization and precision in keratoplasty, several concerns, such as cost-effectiveness, limit its wider clinical adoption.

Seven patients (14 eyes) with symptomatic CCH received T.E.F.A.R.C. in both eyes. The symptoms before and after the procedures were compared and surgical complication was evaluated. The mean follow-up time was 13.7 ± 2.14 months. After the operation, resolution of the symptoms was reported in 12 eyes (86%). The grade of CCH decreased from 3 to 0 in all 14 eyes, and the restoration of inferior conjunctival surface and fornix within 1 day was also observed in all eyes. Most patients had localized injection and mild chemosis after the operation, which mostly recovered within 3 weeks. No complication or recurrence of CCH was reported after 1 year of follow-up.
