HERNANDEZ SILVA, Juan Raúl et al. LASIK-LASEK in refractive defects after cataract surgeries. Rev Cubana Oftalmol [online]. 2008, vol.21, n.2, pp. 0-0. ISSN 1561-3070.

INTRODUCTION: The treatment of cataract is surgical, very good results in visual recovery of patients are achieved; however, some unexpected results may appear after surgery. The purpose of this study was to evaluate the characteristics of the studied persons by their age, the biometric and keratometric values before the cataract surgery, the refractive surgery and the excimer laser technique used in patients who were operated on from May 2005 to July 2007 at "Ramón Pando Ferrer" Cuban Institute of Ophthalmology. METHODS: A prospective, longitudinal and descriptive study was conducted in those patients operated on from cataract, who developed a residual refractive defect - error or refractive surprise- and were performed an excimer laser surgery. The characteristics of the studied persons by their age, the biometric and keratometric values prior to the cataract surgery and the refractive surgery as well as the used excimer laser technique were evaluated. RESULTS: This study revealed the prevalence of the 40-59 years-old age group, the most frequent refractive error was myopia, the axial length induced a refractive surprise contributed by the keratometric error; LASIK was the refractive technique that managed to correct the found refractive surprises. CONCLUSIONS: The refractive surprise present in all the patients was myopia. It was shown that the axial length induced a refractive surprise that was the most important outcome derived from a keratometric error, despite the latter being not significant.
