BACKGROUND AND OBJECTIVES The use of topical anesthesia in cataract surgeries has been increasing, especially after the development of phacoemulsification. The objective of this study was to evaluate the efficacy of topical anesthesia associated with sedation for cataract extraction by phacoemulsification. METHODS A prospective study was conducted with 312 patients, ASA I and II, ages 41 to 8...

Progression in phacoemulsification techniques for cataract surgery[1-4] has also led to inevitable changes in the delivery of accompanying anesthesia from general to local modalities [5-7] i.e. retrobulbar, peribulbar, Sub-Tenon and topical anesthesia. General anesthesia is preferred for complicated intracapsular cataract extraction (ICCE) surgery as this technique involves significant manipula...

Submitted on: 06/20/2009 Approved on: 09/10/2009 We declare no confl ict of interest. aBStRaCt Introduction: Needle infiltration of local anesthetic is a painful procedure, thus, a topical anesthetic is a comfortable alternative. However, it is difficult to deliver transcutaneous polar drugs. Iontophoresis is a noninvasive technique that uses electrical current for releasing electrically charge...

965 percent decrease in resistance in an airway in which the wall area was 45 percent. Since an increase in airway wall thickness is one of the pathogenetic mechanisms that leads to the decrease in maximal expiratory flow in patients who have COPD,2 it would be expected that those patients with more severe baseline airflow obstruction would have thicker airway walls. Thus, another explanation f...

OBJECTIVES Evaluation of pain during and after phacoemulsification with topical anesthesia in patients with senile cataract and investigation of factors related with pain. MATERIALS AND METHODS Ninety-two adult patients scheduled for routine clear corneal phacoemulsification with topical anesthesia who had no previous cataract surgery in their fellow eyes were included in the study. Verbal pa...

BACKGROUND With the emergence of new laser and dermatologic procedures, the need for more effective topical anesthesia continues to grow. There are now several topical anesthetics that are being used prior to laser and surgical procedures. OBJECTIVE To compare the degree and duration of anesthesia produced by four commonly used topical anesthetics, we performed a prospective study investigati...

PURPOSE To evaluate if the standard anesthetic regimen - topical combined with intracameral anesthesia without sedation - in a population-based cohort of unselected cataract surgery cases is adequate, optimal, and good practice, or if improvements are necessary. METHODS We conducted a prospective, observational study on all cases of cataract surgery during a 1-year period at one institution (...
