Armando Capote Cabrera,I Dr. Yoriel Cuan Aguilar,I Dr. La Habana, Cuba. II Hospital Militar "Dr. Carlos J. The average keratometry through the medical history method was estimated and compared with the keratometry values provided by Pentacam : value of the corneal apex of color maps, True Net Power total central keratometric value and Equivalent K-reading Power equivalent keratometric reading as well as the total keratometric value of 3.

The mean preoperative keratometry of the medical history was estimated and then compared with the preoperative keratometry measured by Pentacam. Results: the values that did not show significant statistical differences in comparison with that of the clinical history method were the Equivalent K-reading Power equivalent keratometric readings and the equivalent keratometric readings of 3. The rest of the measurements differed in a significant way.

There were differences among the preoperative keratometries. Conclusion: Pentacam provides corneal powers that did not differ statistically from those of the clinical history method in hypermetropic eyes having previous surgery with Excimer laser.

Keywords: keratometry, refractive surgery, Excimer laser, hypermetropia. El problema que surge con tales casos es el de calcular una lente intraocular LIO de potencia adecuada. Esto no siempre es correcto. Los mapas que calculan la potencia paraxial son el Mean Total Power en el orbscan y el Net Power en el pentacam poder corneal neto, Verdadero.
