Abstract Details


To evaluate refractive, pachymetric, topometric, and visual rehabilitation changes in Athens Protocol applied in keratoconic patients.

Setting: Clinical and Research Eye Institute, Athens, Greece


One hundred forty-four keratoconic cases subjected to the Athens protocol procedure were studied for visual acuity, keratometry, pachymetry, and anterior surface irregularity indices for a mean of 10.5 years (10 to 13) postoperatively by Scheimpflug imaging (Oculus Optikgeräte GmbH, Wetzlar, Germany).


Mean UDVA and BCVA showed a statistically significant improvement at one-year follow-up and remained stable until the ten years follow-up (UDVA, 0.55±0.31 decimal). K flat and K steep decreased significantly postoperatively (K2 steep meridian, 47,5±8,81D) and remained stable during the follow-up period. The value for the Index of Height Decentration continued to decrease over time (0,074±0.031 µm at 10 years postoperatively). One hundred forty one eyes (97.9%) showed no further keratoconic progression, and three eyes showed progression at 10 years follow-up as documented by corneal topography.


The Athens Protocol appears to be a safe, effective and predictable alternative in the management of progressive keratoconus.
