Femtosecond laser arcuate keratotomy for the correction of high astigmatism after keratoplasty.
2 Earlier surgical procedures like Radial keratotomy, Arcuate keratotomy and Photorefractive keratectomy proved to be successful in quantitative improvement of refractive error, however it was noticed that they degrade the quality of vision by reducing night vision clarity, glare, halos.
Corneal refractive surgery includes laser eye surgery (LES) involving corneal ablation by excimer laser; corneal addition procedures such as intracorneal ring segments and epikeratophakia; corneal relaxation procedures such as radial keratotomy (RK), arcuate keratotomy (AK) limbal relaxing incisions; and thermokeratoplasty.
ARCUATE KERATOTOMY: In which 6-7 mm length incisions of 80% thickness are performed on the steep axis, however arcuate keratotomy near the limbus heals quickly leaving minimal astigmatic correction effect and if it is away from limbus, it results in unstable refraction.
The 29 contributions discuss DescemetAEs stripping automated endothelial keratoplasty, limbal stem cell deficiency, corneal graft rejection, intrastromal arcuate keratotomy to reduce corneal astigmatism with a femtosecond laser, and the turnaround technique for overcoming false channel dissection during intacs implantation.
