Evaluación de lente intraocular tórico AcrySof en corrección de astigmatismo concomitante a catarata en el Hospital Carlos Van Buren, Valparaíso.

INTRODUCTION: Cataracts are the main cause of preventableblindness, and its prevalence increases in older adults. There isa considerable percentage of astigmatism concomitant with cataracts,for this reason correct both conditions in a single surgicalprocedure is of interest to increase visual acuity postoperatively.OBJECTIVE: To evaluate the effectiveness of AcrySoftoric intraocular lense implantation for cataract correction withconcomitant astigmatism. MATERIAL AND METHOD: Retrospectivestudy of single group, whose sample was all patientswith cataract and corneal astigmatism with visual acuity equalor less than 0.5 (logMAR) operated by phacoemulsificationwith AcrySof toric IOL implantation, in the Ophthalmology Departmentof the Hospital Carlos Van Buren, between January2009 and September 2010, who met the inclusion criteria. Fromall this resulted 87 eyes of 77 patients, measured visual acuity,keratometry and subjective refraction before and after surgery.RESULTS: Patients were evaluated on days 1, 7 and 30 of postoperatory.61.33% and 79.31% of the operated eyes obtained anuncorrected and corrected visual acuity, respectively, greater orequal to 20/40. The median subjective refraction cylinder decreasedsignificantly after surgery. DISCUSSION: AcrySof toricintraocular lense implantation during phacoemulsification surgeryfor cataract correction proved an effective method for correctionof concomitant astigmatism.
