Objetivo: El objetivo del estudio fue describir los resultados visuales y queratométricos de pacientes con queratocono sometidos a tratamiento con crosslinking (CXL).

MÉtodo: Estudio retrospectivo de 277 ojos de 144 pacientes con queratocono progresivo que se sometieron a CXL. Se obtuvieron mediciones topográficas antes del procedimiento y 12 meses después. La agudeza visual corregida (AVC), la queratometría más plana (K1), la queratometría más curva (K2), el promedio de la queratometría (Kprom), el cilindro, el eje de K1, el eje de K2 y el valor paquimétrico del punto de la córnea más delgado fueron las variables evaluadas.

Resultados: A los 12 meses de seguimiento, los valores de AVC mejoraron. Hubo disminuciones estadísticamente significativas en K1 (p = 0,001), K2 (p = 0.000), eje de K1 (p = 0.000), eje de K2 (p = 0.004) y Kprom (p = 0.025). El análisis de correlación mostró que la AVC, la K1, la K2, el eje de K2, el Kprom y el cilindro preoperatorios, así como la K1, la K2, el Kprom y el cilindro posoperatorios, afectan significativamente la agudeza visual a los 12 meses de seguimiento.

Conclusiones: El CXL es un tratamiento eficaz para mejorar la AVC a 1 año de seguimiento en el grupo de pacientes estudiados. Los valores de K preoperatorios y posoperatorios, y la AVC preoperatoria, se correlacionan de forma significativa con la AVC a los 12 meses de la aplicación del CXL.

Objective: The present study aimed to report the outcomes of patients with progressive keratoconus who were treated via conventional crosslinking (CXL).

Method: This retrospective study included 277 eyes of 144 patients with progressive keratoconus who underwent CXL. Topographical measurements were obtained preoperatively and twelve months postoperatively. The best corrected visual acuity (BCVA), flat keratometry (K) value (K1), steep K value (K2), average K value (avgK), K1 axis, K2 axis, pachymetry value and cylindrical value were the studied measures.

Results: At the 12-month follow-up, the mean BCVA values were improved. Statistically significant decreases in K1 (p = 0,001), K2 (p = 0.000), K1 axis (p = 0.000), K2 axis (p = 0.004) and avgK (p = 0.025) were observed. The correlation analysis revealed that the preoperative BCVA, K1, K2, K2 axis, avgK and cylinder as well as postoperative K1, K2, avgK and cylinder values significantly affected visual acuity at the 12-month follow-up.

Conclusions: CXL was an effective treatment to improve best corrected visual acuity. The preoperative and postoperative K values, preoperative BCVA had a statistically significant correlation with BCVA at 12 months after CXL treatment.

Objective: To evaluate early keratometric and refractive results after intra-corneal rings surgery in keratoconus patients.

Method: 50 eyes of 25 patients with keratoconus within stage 2 and 3, underwent intra-stromal corneal rings surgery by using the femtosecond surgical laser, one month after surgery, corneal keratometries and patient refraction were compared vs pre-operative ones.

Results: Mean pre-operative low keratometry was 48.

Objective: To determine the correlation of higher order aberrations in anterior corneal surface and degree of keratoconus measured with a Scheimpflug camera.

Material And Methods: A descriptive, cross-sectional study was conducted on 152 eyes (both eyes of each patient) of patients with keratoconus, from January 2009 to April 2014. An examination was performed on the corneal aberrometry in the anterior corneal surface, and topographic mapping (by Amsler and Muckenhirn classification) was used to determine the degree of keratoconus.
