creating tunnel for INTACS and pocket for riboflavin creating tunnel for INTACS and pocket for riboflavin administration using Femtec Femtosecond laser.administration using Femtec Femtosecond laser.

MethodsMethods

Intrastromal tunnels created in Intrastromal tunnels created in 70% of corneal depth, 70% of corneal depth,

followed by corneal pocket followed by corneal pocket creation in 100 micron depth creation in 100 micron depth

Intacs placement combined with Intacs placement combined with UVA irradiation after UVA irradiation after intrastromal injection of 0.1% intrastromal injection of 0.1% riboflavin.riboflavin.

ResultsResultsFour eyes of three patients had combined approach of Intacs Four eyes of three patients had combined approach of Intacs and cross-linking treatment. All of them had significant and cross-linking treatment. All of them had significant reduction in keratometry values and spherical equivalencereduction in keratometry values and spherical equivalence..
