Randomized Controlled Trial Clinical TrialEffect of midazolam on anxiety level and pain perception in cataract surgery with topical anesthesia.
To study the effect of sedation on patients' anxiety level and perception of pain during cataract surgery under topical anesthesia. ⋯ Patients who had cataract surgery under topical anesthesia were highly satisfied with their operative experience and reported minimal pain during surgery. Anxiety levels diminished after arrival at the hospital, possibly because of reassurance by experienced staff. Intravenous midazolam did not seem to significantly reduce pain or anxiety.

Comparative StudyEstimation of pupil size by digital photography.
To evaluate a digital photography method of pupil size estimation over a broad range of illumination conditions and to compare this method with common clinical techniques. ⋯ Estimation of pupil size by digital photography was more repeatable and accurate than estimates by common clinical techniques over a wide range of illumination. Although not as quick as other methods, digital photography is relatively inexpensive, permits lasting documentation, and allows independent grading suitable for clinical research purposes.
