Agudeza visual prequirurgica y postquirurgica en cirugía de catarata de mínima incisión en el Hospital Alfredo Noboa Montenegro Guaranda - de enero 2011 a diciembre del 2013.

Abstract

Objective: To evaluate the preoperative and post-operative visual Acuity in Cataract surgery of minimal incision. Method: A longitudinal descriptive study of a cross section point was made, and the following variables such as: age, sex, type of cataract, visual acuity and eye affected were analyzed, by getting the results of a massive program of cataracts developed at the Hospital Alfredo Noboa Montenegro of Guaranda during the years 2011 to 2013. The universe was constituted by 256 eyes with senile cataract diagnosis, one eye per patient. Data were processed and analyzed through descriptive and percentage techniques. Results: From 256 eyes, 136 where in the right eye (53.13%), 120 (46.8%) in the left eye. The predominant age group was: 70-79 years old (36.72%) 94, followed by people older than 80 years of age (30.46%) 78, 60 to 69 years (18.75%)48, 50 to 59 years (14.07%)36; In gender: Men (55.80%) 143 and women (44.20%) 113; The preoperative visual acuity: Perception of light (24,60%) 63, count fingers vision at one meter(17.18%)44, 20/400 (12.89%)33, movement of hands(10.55%)27; The post-operative visual acuity without correction: 20/60 (15.62%)40, better view 20/40 (11.72%)30, 20/80(10,94%) 28, 20/100 (13.30%) 34,20/160 (7.81%)20, 20/200 (6.64%)17,20/400 (8.98%)23; count fingers at two meters (1.95%)5; movement of hands(5.47%)14; Perception of light(0.78%)2; type of nuclear cataract (90.62%)232, cortical (5.07%)13, posterior subcapsular(4.29%) 11. Conclusion: In extracapsular cataract surgery, the minimal incision is effective; a significant recovery of visual acuity and better far distance without correction where reached.
