“…1,[15][16][17] Initially, this was performed via a scleral tunnel and thus required sutures, so retrobulbar and peribulbar anesthesia were preferred. 13,18 Because the corneal incision is inherently small, stepped, and self sealing, very little manipulation is required and this has allowed the use of sub-Tenon [19][20][21][22] and topical anesthesia. 13,[23][24][25] Any anesthesia technique for cataract surgery must strive for patient safety, comfort, and the attainment of safe conditions for the necessary surgery.…”

Various aspects of local anesthesia for cataract surgery, such as the anesthetic agents and their interaction with ocular nerve supply, anesthesia requirements, available clinical techniques and their inherent complications are reviewed. A comparative evaluation of clinical techniques in terms of efficacy, akinesia, and patient-perceived pain during both anesthesia administration and intraoperative cataract surgery is presented, along with the prevailing practice patterns of anesthesia techniques among refractive surgeons in the United Kingdom and United States. More randomized clinical trials are needed to facilitate statistical methods of metaanalysis to establish convincingly the overall benefits and efficacy of the various local anesthesia procedures in cataract surgery. The wide scope of the present review is of relevance in structuring ophthalmology and anesthesia specialist training programs for junior staff.

“…Newer techniques like small corneal or limbal incisions, phacoemulsification of the lens nucleus [3,9,21,22], and implantation of foldable intraocular lenses [28] have made it possible to switch from general anesthesia to local anesthesia [12,14,19], including retrobulbar or peribulbar injections of local anesthetics. The advent of small, stepped, and self-sealing corneal incisions, in which very little manipulation is required, has allowed the use of Sub-Tenon [4,15,16,18] and topical anesthesia [5,8,20] Peribulbar injection of an aesthetic agents has been used for more than a century in cataract surgery and various modifications have been devised over the last two decades to reduce the risks of injury of intraorbital structures during surgery [17]. The blind insertion of a needle into the retrobulbar space has never been completely free from sight and life threatening complications [17].…”

Introduction: This study was conducted for evaluating and comparing levels of patient discomfort during phacoemulsification and intraocular lens implantation under topical and peribulbar anesthesia and comparative assessment of intra-operative complications. Methods: It is a hospital based comparative study on patients who underwent phacoemulsification from January'2015 to March'2015. Patients were randomly distributed to peribulbar or topical anesthesia. Parameters like age, surgery duration, blood pressure, oxygen saturation and intraoperative pain were compared in two groups. Results: 51 patients underwent phacoemulsification under topical anesthesia and 49 patients underwent phacoemulsification under peribulbar anesthesia. No statistical differences were found in surgery duration, intra-operative complications, pain, blood pressure or Oxygen saturation (SPO2). Topical group did not require additional subconjunctival injection. 4/49 (8.16%) in peribulbar group required additional topical anesthesia. This was statistically significant (p=0.04). Anesthesia related complications were only seen in peribulbar group. Conclusion: Surgical complications and patient comfort did not differ in two groups. There is no significant difference in topical and peribulbar anesthesia with respect to intra-operative pain level and intra-operative complications. Also topical anesthesia is minimally invasive. In view of results obtained, study suggests usefulness of topical anesthesia as compared to peribulbar anesthesia for cataract surgeries.
