Corneal densitometry changes after femtosecond laser-assisted intracorneal ring segments implantation in keratoconus. [PDF]

Med Hypothesis Discov Innov Ophthalmol
Background: Intrastromal corneal ring segments are commonly implanted in the corneas of eyes with mild-to-moderate keratoconus; however, changes in corneal densitometry (CD) after implantation are a matter of debate in the current literature.
