Reliability study of biometrics "do not contact" in myopia.

PURPOSE: The aim of the study is a comparison between the actually achieved after surgery condition versus the expected refractive condition of the eye as calculated via a biometer. MATERIALS AND METHODS: The study was conducted in a random group of 38 eyes of patients undergoing surgery by phacoemulsification. RESULTS: The mean absolute error was calculated between the predicted values from the measurements with the optical biometer and those obtained in the post-operative error which was at around 0.47% CONCLUSIONS: Our study shows results not far from those reported in the literature, and in relation, to the mean absolute error is among the lowest values at 0.47 ± 0.11 SEM.

Persistent vertical diplopia after cataract surgery: a case report.

Diplopia is an event that can occur following cataract surgery, although its rate of occurrence is limited and ranges from 0.67% to 0.85%. The authors present a case of vertical diplopia arising after peribulbar anaesthesia for cataract surgery in a 78-year-old woman. Diplopia appeared at distance in primary position, while at near there was binocular single vision. Stereopsis was present at the Lang I - II Test, but the Wirth Test was incomplete. Although in the literature the frequency of these "accidents" is very limited, we think it is relevant to emphasize the need to perform pre-operative routine using a careful orthoptic examination along with a thorough medical, especially strabological, history.
