%X Se realiz車 un estudio retrospectivo, transversal y comparativo de un grupo de 400 ojos de 270 pacientes operados de miop赤a desde -1 a -7 dioptr赤as (D), en la Cl赤nica Internacional Oftalmol車gica "Camilo Cienfuegos" con l芍ser excimer. A estos pacientes se les realiz車 estudios completos en el preoperatorio y posoperatorio y una evoluci車n de 2 a os. Las variables estudiadas fueron: queratometr赤a (Q), agudeza visual sin cristales (AV s/c) y con cristales (AV c/c), esfera, cilindro, paquimetr赤a. Se realiz車 una comparaci車n de todas ellas antes y despu谷s de la cirug赤a. Tambi谷n se registraron las complicaciones aparecidas durante los cinco primeros d赤as de la operaci車n. Se utiliz車 el procesador estad赤stico STATISTICA para Windows 98 con el que se elaboraron estad赤sticas descriptivas y comparativas, y la prueba t de Student para muestras dependientes con valor de significaci車n para p < 0,05. Llegamos a la conclusi車n de que la AV s/c aument車 6 l赤neas como promedio; en la totalidad de los casos se logr車 una esfera posoperatoria inferior a 1D. Hubo una disminuci車n del astigmatismo posoperatorio y las complicaciones posoperatorias fueron leves y con una total recuperaci車n visual A retrospective cross-sectional and comparative study of a set of 400 eyes from 270 patients was made. They had been operated on from myopia ranging 1-7 dioptries, using LASEK technique for myopia correction, at ※Camilo Cienfuegos§ International Ophthalmology Clinics. Complete studies of these patients were performed at the preoperative and postoperative phases up to 2 years of evolution. The examined variables were keratometry(k), visual acuity without and with glasses, sphere, cylinder, pachymetry, all of which were compared before and after surgery. Also data were gathered on complications in the first five days of operation. The statistics processor called STATISTICA operating on Windows 98 served to work out descriptive and comparative statistics. Student t test was used for dependent samples with significance values p<0,05. We concluded that visual acuity without glasses increased 6 lines as an average; in all these cases, the postoperative sphere of refraction was under 1D. Postoperative astigmatism was reduced, postoperative complications were slight, with full visual recovery
