Abstract Details


Evaluate refractive, pachymetric, topometric and visual rehabilitation changes in AP applied in KC.

Setting: Clinical and Research Eye Institute, Athens, Greece


24 consecutive eyes of 16 KC patients (pts.) underwent AP with adjunct CXL 6mW/cm2 for 10 minutes instead of 15. We evaluated refraction (RE), acuity, Scheimpflug and OCT tomography parameters for a mean of 2.5 years (1 to 8).


Mean changes: RE: -3.5 to -1.25 (�Â�±3.6) to -1.15 (�Â�±2.55), UDVA 0,2 to 0,65; CDVA 0,38 to 0,71; steepest keratometry in Diopters: 52,5�Â�± 5.72 to 46,5�Â�± 4.81, Index of Height Decentration 0,235 to 0,054, thinnest cornea 458�Â�±27 to 385�Â�±32 �Î�¼m. There was no further KC progression, 1 cases of overcorrection developed. 11 pts. functioned without, while 4 with spectacles and/or soft contact lenses. 1 pts. required scleral lenses.


AP appears to be a safe, effective and predictable retreatment in the management of visually challenging stabilized KC.
