[Chinese expert consensus on femtosecond laser-assisted keratoplasty (2022)].

Corneal transplantation, which can be divided into therapeutic keratoplasty and optical keratoplasty, is the main method to restore vision for patients with corneal blindness. The keys to optical keratoplasty are the regular excision and preparation of donor and recipient corneas, as well as well-developed suturing skills to reduce surgically induced astigmatism. Traditional keratoplasty mainly relies on trephination to prepare the corneal graft and the recipient bed, but this procedure lacks precision, which is an important factor affecting postoperative vision recovery. In this regard, femtosecond laser-assisted keratoplasty (FLAK) can get more precise results compared with the traditional trephine-assisted keratoplasty, thereby achieving better optical keratoplasty effects. FLAK requires the cooperation between corneal refractive surgeons and corneal transplantation surgeons, and the surgical procedure also differs from that of traditional trephine-assisted keratoplasty. To promote and standardize the implementation of FLAK in China and to provide guidance on its clinical practice, the Cornea Group of Ophthalmology Branch of Chinese Medical Association has formulated this consensus on the indications, surgical design and procedures, complications and perioperative medication management of FLAK after thoroughly discussing the domestic and foreign research results collected, combined with the clinical experience of experts in this field.
