ROJAS ALVAREZ, Eduardo  and  GONZALEZ SOTERO, Janet. Correlation between corneal morphometry and ametrophy in LASEK. Rev Cubana Oftalmol [online]. 2014, vol.27, n.1, pp.38-50. ISSN 0864-2176.

Objective: to establish the correlation between the corneal morphometric changes and treated ametropia one year after the corneal surgery with Excimer laser using LASEK. Methods: prospective, observational, descriptive and longitudinal study was conducted. The sample was 111 eyes from 56 patients, who were operated on with LASEK at "Abel Santamaría" hospital in Pinar del Río province, Cuba from November 2010 through June 2011. NIDEK´s Confocal ConfoScan 4 microscopy was used to obtain and to study the in vivo corneal tissue images. The equipment was set in automatic scanning, with central fixing, image taking speed of 25 image/sec, 500x magnifying, lateral resolution of 0,6 im/pixel, 350 scanned images, and operating distance of 1,98 mm. Summary statistics, Pearson´s correlation and linear regression methods were used. Results: after LASEK, an statistically significant correlation was observed between the size of treated ametropia and the studied variables pachymetry, corneal haze thickness and keratocyte density in the anterior stroma Conclusions: as the size of ametropia treated with LASEK increases, the values of pachymetry and keratocyte density in the anterior stroma decreases.
