MARTINEZ LEGON, Zoila C et al. Myopic astigmatism after LASIK in patients operated at "Enrique Cabrera" Ophthalmology Center from Havana . MEDISAN [online]. 2012, vol.16, n.6, pp. 888-895. ISSN 1029-3019.

A descriptive, longitudinal and retrospective study was carried out in 264 patients operated on myopic astigmatism by means of LASIK at "Enrique Cabrera" General Teaching Hospital from Havana, during 2009, in order to characterize them after surgical treatment. Female sex (61.7%) and age group between 20 and 30 years (41.3%) prevailed in the case material, as well as preoperative and postoperative visual acuity of counting fingers of 0.2 (62.8%) and 0.6 to 1.0 (98.1%) respectively. After the treatment have been applied, in 95.0% of patients from the series the sphere decreased to values between 0.00 and -1.00 diopters, and the cylinder, in 98.7%, measuring less than -1.50 diopters. Keratometric values from 41.25 to 43.00 diopters were present in 72.1% of those affected and the spherical equivalent showed a substantial approach to emmetropia in 82.3% of the surgeries, with a range between -1,00 and 0,00 diopters.
