ABSTRACT
OBJECTIVE: To evaluate the efficiency of long-term cataract surgery using low-cost intraocular lens implantation in community campaigns. METHODS: Fifty-eight randomly selected patients were evaluated four years after phacoemulsification and Ioflex intraocular lens implantation. Causes of low visual acuity related to the intraocular lens were evaluated, and treatment costs were calculated. RESULTS: The mean age of patients was 72±10.2 years. Four years after surgery, 25 eyes (43.0%) had decreased visual acuity related to the intraocular lens: posterior capsule opacification was noted in 24 eyes (41.3%), and intraocular lens opacification was noted in one eye (1.7%). The total cost of the post-surgical complication treatments represented 6.3% of the initial budget of the entire surgical patient group. CONCLUSIONS: The efficiency of cataract surgery with low-cost Ioflex intraocular lens implantation was significantly reduced in a long-term follow-up study because postoperative complications related to intraocular lenses emerged at higher rates than when the gold-standard treatment was used.

En este estudio comparamos el cálculo del poder del lente intraocular por dos métodos: uno sin ecografía tomando una constante de 20D para el cristalino y la refracción del mismo ojo o en ocasiones del contralateral, y el otro con ecografía y la fórmula SRK. Fueron 22 ojos en total a los que se les realizó EECC más lente intraocular de cámara posterior. Tuvieron un seguimiento postoperatorio de 3 meses en promedio, obteniéndose los siguientes resultados: En el grupo sin ecografía se obtuvo una refracción final de + 1.00 a - ¿.75 y en el método con ecografía de + 1.50 a - 0.50. Nuestras conclusiones fueron: que el cálculo del poder de lente intraocular sin ecografía es posible en pacientes con ametropías menores de 2.50 D y en ametroías altas, anisometropías o duda en el antecedente refractivo ocular del paciente es necesaria la ecografía
