To report short term results in a study of corneal crosslinking (CXL) analysed with Pentacam (Oculus Optikgërate, Deutschland) in the management of progressive keratoconus.
Crosslinking was performed using 0.1% riboflavin and ultraviolet A (UVA) irradiation. Radiant energy was 3 mW/cm2 for a 30 min exposure at 1 cm from the corneal apex. At each review, a full clinical ophthalmic examination was performed including refraction, best corrected visual acuity, corneal thickness, corneal topography and confocal microscopy.
The analysis included 10 eyes of 9 patients with a minimum follow up of three months. Topographic analysis showed a mean K reduction of 1.08 ± 0.65 diopters (D) in the central 3.0 mm. Statistical analysis of IOP, best corrected visual acuity and endothelial cell count did not show statistically significant differences (p>0.05). Mean central corneal thickness (CCT) measured with optical pachymetry showed a reduction of 24.87 ± 74.71 µm. At a minimum 3 months follow up none of the patients presented any complications or adverse events.
Our short term results suggest that CXL is a minimum invasive procedure, with little stress for the patients, with few side effects. In this small cohort of patients we observed a reduction on the CCT measured with the Pentacam 3 months after the CXL
