tetracaine Topical Anesthesia for myringotomy
Laryngoscope, 2001Co-Authors: Ronald Hoffman, Chunlun J LiAbstract:Objectives/Hypothesis To study the efficacy and safety of Topical tetracaine Anesthesia for office myringotomy and myringotomy with a tube. Study Design Retrospective review of patients undergoing office myringotomy, with or without tube insertion, performed over a 4-year period. Methods A Topical solution of 8% tetracaine base in 70% isopropyl alcohol was used in 381 ears. Five to 10 drops of the solution were applied to the tympanic membrane for 10 to 15 minutes and aspirated. Myringotomy was performed either with a myringotomy knife or with a CO2 laser (OtoLAM). Results Topical tetracaine was used in all 231 ears (100%) undergoing myringotomy without a tube and 150 of 212 ears (71%) undergoing myringotomy with a tube. Tetracaine alone was effective in providing tympanic membrane Anesthesia in 95% of myringotomy without a tube (220 ears) and in 93% of myringotomy with a tube (139 ears). There were six complications, including five cases of severe vertigo and one unusual prolonged, transient facial nerve weakness. Conclusion Topical tetracaine is efficacious and safe for use in office myringotomy.

Topical Anesthesia for small incision self-sealing cataract surgery: A prospective evaluation of the first 100 patients
Journal of cataract and refractive surgery, 1993Co-Authors: Robert M. KershnerAbstract:Small incision self-sealing cataract surgery has created the opportunity to use less invasive Anesthesia. One hundred patients were evaluated in a prospective study using a new technique of Topical Anesthesia to allow small incision construction, intercapsular phacoemulsification, and small incision intraocular lens implantation without a peribulbar or retrobulbar injection. This study demonstrated that Topical Anesthesia avoids the risk of globe perforation, retrobulbar hemorrhage, and prolonged postoperative akinesia of the eye and is effective for intraoperative Anesthesia for cataract surgery.

a comparison of retrobulbar versus Topical Anesthesia in trabeculectomy and aqueous shunt surgery
Journal of Glaucoma, 2017Co-Authors: Alex Theventhiran, Muhammad Shabsigh, Carlos Gustavo De Moraes, George A Cioffi, Mohammed Kamel, Dana M Blumberg, Lama A AlaswadAbstract:PURPOSE The purpose of this study was to compare the required supplemental Anesthesia and postoperative patient pain score in individuals undergoing glaucoma surgery under Topical Anesthesia (TA) versus retrobulbar Anesthesia (RB). MATERIALS AND METHODS A retrospective, interventional, comparative cohort study of 261 eyes of 225 patients undergoing glaucoma and combined glaucoma with cataract surgery were included in the study. The main outcome measures were the amount of supplemental, systemic intraoperative Anesthesia used and the postoperative pain scale between patients undergoing TA versus RB Anesthesia. A secondary analysis was performed between combined glaucoma and cataract surgery versus glaucoma surgery alone. RESULTS About 6.2% patients complained of pain after glaucoma surgery (8.1% among TA group and 3.1% among RB group; P=0.049). Overall, pain tended to be mild with a mean score of 0.32 of 10 for TA and 0.08 of 10 for RB (P=0.027). The amount of IV anesthetics used intraoperatively was lower in the RB Anesthesia compared with the TA group (midazolam, P=0.042; fentanyl, P 0.350) between eyes undergoing combined versus glaucoma surgery alone. CONCLUSIONS Although supplemental Anesthesia and pain scores were statistically increased in the Topical group, the prevalence and the severity of pain was low. Therefore, TA is feasible and a reasonable option for glaucoma surgery. Furthermore, this conclusion applies when glaucoma surgery is performed alone or in combination with the other eye surgery.

Topical versus peribulbar Anesthesia in cataract surgery
Journal of Cataract and Refractive Surgery, 1996Co-Authors: Stan J Roman, F Auclin, Martine M UllernAbstract:Abstract Purpose: To compare the use of Topical Anesthesia with that of peribulbar Anesthesia in cataract surgery. Setting: Quinze-Vingts Hospital, Paris, France. Methods: This prospective study comprised 45 patients who had phacoemulsification and intraocular lens implantation in both eyes with 1 to 9 months between surgeries. Each patient had peribulbar Anesthesia for one surgery and Topical Anesthesia for the other. The Anesthesia method for the first eye was randomly selected. After surgery, patients were asked to rate their pain and whether they preferred one Anesthesia technique over the other. Results: When Topical Anesthesia was given, 82.2% of patients required no intravenous medications. Overall, 62.2% preferred Topical over peribulbar Anesthesia, with most patients citing the lack of periocular injection as the reason. Conclusion: Despite the increased technical difficulty, Topical Anesthesia proved an effective alternative to peribulbar Anesthesia for cataract surgery that avoids the risks of periocular injection and reduces the need for intravenous medications.

Topical versus peribulbar Anesthesia in clear corneal cataract surgery
Journal of Cataract and Refractive Surgery, 1996Co-Authors: Martin Zehetmayer, U Radax, Christian Skorpik, Rupert Menapace, M Schemper, Herbert Weghaupt, U ScholzAbstract:Abstract Purpose: To evaluate the efficacy of Topical Anesthesia as an alternative to peribulbar Anesthesia in clear corneal cataract surgery. Setting: Department of Ophthalmology, University of Vienna, Austria. Methods: In this prospective, double-blind clinical trial, 36 patients had bilateral cataract surgeries performed from 1 to 3 months apart. Half of the patients had Topical Anesthesia for the first surgery and peribulbar Anesthesia for the second surgery. The other half had peribulbar first and then Topical. All surgery was done using a temporal clear corneal approach and bimanual phacoemulsification followed by in-the-bag intraocular lens implantation. Subjective pain was assessed using a visual analog scale of no pain (0%) to worst pain imaginable (100%) and intraoperative motility using a rank scale of adverse motility (−5) to ideal patient cooperation (+5). Results: Subjective pain was comparable whether Topical or peribulbar Anesthesia was used (mean 10.75 versus 10.97%; P > .6). Patient cooperation (motility) was significantly better when Topical Anesthesia was used (+2.16 versus +1.11; P = .03). There were no significant differences in complications. A peribulbar block was given in addition to the Topical Anesthesia in two cases. Conclusions: Topical Anesthesia is a safe, effective alternative to peribulbar Anesthesia in clear corneal cataract surgery.
