Title : Femtosecond assisted stromal lenticule addition keratoplasty
Abstract:
Currently, additive keratoplasty is a practically useful method in keratoconus, hyperopia, and reduction of tube exposure.
It is called CAIRS, corneal allogeneic intrastromal ring segments; FAISCG, Femtosecond-assisted intrastromal corneal graft; FLEx, Femtosecond Lenticule Extraction; LIKE, lenticule intrastromal keratoplasty; SFII, small-incision femtosecond laser-assisted intracorneal concave lenticule implantation; SILK, femtosecond laser-assisted small incision sutureless intrastromal lamellar keratoplasty; SLACK, femtosecond laser-assisted stromal lenticule addition keratoplasty; SMILA, FSL-assisted small-incision lenticule addition; SMILE, Small Incision Lenticule Extraction, and CuSLI, Customized Stromal Lenticule implantation. Illustrations of implantation of a myopic lenticule with different shapes or profiles of donut-shaped tissue Customized or hyperopic SMILE lenticule is for ectasia. We observed the modest improvement in the keratometric parameters of the cornea, the improvement in mean values from the preoperative (Pentacam) mean values aberration between the preoperative and 24 months post-op) (µm). During the follow-up period, densitometry decreased, which indicates more corneal clarity and better light scattering. In agreement with previous reports about densitometry after CXL or ICRS implantation, the highest values were illustrated in the anterior corneal layer after additive keratoplasty. Optical coherence tomography showed smooth attachment of the lenticule to the stromal layer with visible boundaries. preoperatively and after 1, 3, and 6 months postoperatively. MS-39 uses Spectral-domain OCT (SD-OCT) and Placido Disk corneal topography to obtain measurements from the anterior segment of the eye.
Audience take-away:
- Regarding the safety, stability, and reversibility of additional keratoplasty in different fields of corneal surgeries, the processing of lenticule banking seems a necessity.
- Advanced monogram using artificial intelligence can improve the efficacy and predictability of additional keratoplasty from the refractive aspect.
