Abstract

LANTIGUA MALDONADO, Isabel Cristina et al. Results of myopic LASIK obtained at “Ramón Pando Ferrer” Cuban Institute of Ophthalmology. Rev Cubana Oftalmol [online]. 2012, vol.25, n.1, pp.12-20. ISSN 0864-2176.

Objective: To evaluate the results and the stability of the myopic Lasik carried out in “Ramón Pando Ferrer” Cuban Institute of Ophthalmology. Methods: A prospective, descriptive and comparative study was conducted. The universe of study was made up of the patients operated on by LASIK (4011 eyes) from the beginning of the corneal refractive surgery with excimer laser in our center in 2005. The patients were selected from those that had been studied for ametropy correction one year after the surgery. The studied variables were keratometry, better visual acuity without correction, better visual acuity with correction, spherical equivalent, pachymetry and topography, and the obtained results were compared before and at one year of the surgery. The paired T test served to analyze the results with statistical significance of p < 0.05. Results: Significant changes took place in keratometry and spherical equivalent that brought about improved visual acuity without correction for distance vision. The best visual acuity with correction remained the same before and after the surgery. Pachymetry remained within safe limits. There was no topographical pattern with evidences of complications. Conclusion: All the variables underwent significant changes and showed a tendency to emmetropia. The topographical patterns correspond to central ablations (myopias). The pachimetry values were within safe limits.

Keywords : LASIK; myopia; keratometry; spherical equivalent; visual acuity.
