Abstract Details


To evaluate the effect of Penetrating keratoplasty (PK) on corneal keratometry and the anterior segment parameters obtained with the Sirius corneal topography.


Cornea and Refractive Surgery Department


A total of previously diagnosed with inevitable penetrating keratoplasty indication of 15 keratoconus patients’ 15 eyes (7 men, 8 women, 40±14.9) were evaluated preoperatively and 3 months postoperatively with the Sirius corneal topography. (Costruzioni Strumenti Oftalmici, Italy). The preoperative and postoperative measurements of Keratometry(K), anterior chamber depth (ACD), anterior chamber volume (ACV), anterior chamber angle(ACA) width were recorded.


Preoperative mean K decreased from 59.48±8.85 to 40.69±6.91 at 3 months after surgery (p<0.0001). ACD decreased from 3.66 ±0.78 mm to 2.95±0.64 mm.(p<0.0001) ACV decreased from 191.27±32.93 to 158.80±34.62. (p<0.0001) ACA decreased from 46.86 ±8.65 to 39.63±9.52.(p<0.0001)


PK significantly decreased the corneal K readings and anterior chamber measurements of depth, angle and volume. These findings has to be considered on possible secondary surgeries like cataract or glaucoma surgeries and apacic IOL implantations.
