The aim of the present study was to evaluate which parameters lead patients to the choice of cataract operation with ambulatory administration. Method and material: The sample studied consisted of 204 registers of two groups, who were submitted for cataract operation. Data were collected by a data register which included demographic variables, the medical history, the level of satisfaction and ophthalmologic measurements. Analysis of data was performed using the SPSS statistical package and Kolmogorov-Smirnov, x2 or Fisher exact test, t-test, while for the test, Mann-Whitney were applied for the statistical process. Results: The sample consisted of 86 men and 118women. The results showed that the final operation outcome (visual acuity-post operationally) between two groups, was equal. The comparison between hospital and ambulatory administration, of average values of the final visual acuity between hospital and ambulatory administration did not present statistically significant difference, p=0.730. The results showed higher satisfaction from administration of cataract operation appeared (73%) on the ambulatory basis compared to the hospital one (24%). Ages onding percentage (10,8%) of patients who came in the private centre, p=0,003. Conclusions: From the above, one could conclude that ambulatory administration of cataract consists in the best alternative solution, because it is danger free, safe and cost-effective.
