Corneal imaging of intrastromal femtosecond laser treatment for presbyopia (Intracor®)

Long-term outcomes of intrastromal femtosecond laser presbyopia correction: 3-year results

“…The incision induced by the femtosecond laser presented as hyper-reflective regular circular lines with a median thickness of 12.5 µm (range 9.5–15.1 µm) 15. After 6 months corneal scars with needle-like pattern appeared in the stroma which were still visible after 12 months 15. Possibly this localised scarring of the cornea can explain the corneal thickening.…”

“…About the reason for this corneal thickening can only be hypothesised. The intrastromal ring cuts have been analysed with confocal microscopy (Heidelberg Retina Tomograph, HRT) and anterior segment spectral-domain optical coherence tomography (OCT) over a period of 12 months 15. With OCT the corneal INTRACOR incisions were initially visible until they almost disappeared after 12 months 15.…”
