“…24 The sub-Tenon's block is probably popular because it provides good akinesia, 25 better intraoperative analgesia, and operating conditions compared with needle blocks and a 50% reduction in posterior capsular tear/vitreous loss compared with topical anaesthesia. 26 Although performance of a sub-Tenon's block requires some dexterity in the handling of surgical instruments but most practitioners develop competence after about 60 blocks. 27,28 The sub-Tenon's block is used for cataract (Table 2).…”

The advent of a new technique that is considered much safer than previously established one leads to its rapid adoption. This usually leads to the identification of previously unreported complications of the new technique, and a re-assessment of its position in clinical care, which is precisely the state of play with the sub-Tenon's block. The sub-Tenon's block was introduced into the clinical practice in early 1990. A systematic recent search of subject headings such as complications of sub-Tenon's block, subtenon, orbital block, orbital block complications, and orbital anaesthesia was performed in Medline, EMBASE, and Cochrane database. Indeed there are complications of sub-Tenon's block published as case reports and the exact incidence of these complications is not known. Management and preventive measures of these complications are described. Although the sub-Tenon's block appears to be relatively safer than needle-based blocks but a proper prospective, randomized, double-blind controlled trial is essential for scientific proof that sub-Tenon's block is better than needlebased blocks.

“…A theoretical drawback of TA is the consequence of the absence of akinesia in possible intraocular pressure fluctuation that may hypothetically make the surgery more dangerous (Davison et al 2007). In a randomized, open-labeled, comparative study of unselected patients, it has been observed a desirable decrease in rate of vitreous loss (0.4% vs 2.5%) and an undesirable increase in iris prolapse (1.7% vs 0.4%) in the TA group, possibly reflecting eye hypertonia due to the lack of akinesia (Jacobi et al 2000).…”

“…A low degree of surgical complications of cataract surgery performed under TA has been shown in a large cases series (Shaw et al 2007). However, a more recent meta-analysis review has demonstrated that, when compared with STI, TA is related with a twofold increase in posterior capsule rupture, demanding anterior vitrectomy (Davison et al 2007). Likewise, TA was recognized as a risk factor for dislocation of nuclear fragments into the vitreous (Mahmood et al 2008).…”

“…3 While TA is believed to have advantage over PA in terms of safety, pain free, free of injection related complications, it has the disadvantage of increase anxiety for the patient as well as surgeon. 4,5 It is debatable to assign the supremacy of one type of anesthesia over the other. 6,7 It is to clear this dilemma; we have conducted a study to investigate the merits and demerits of the two techniques.…”

Background: Due to advancement in phacoemulsification techniques, there has been growing shift from peribulbar anesthesia (PA) to topical anesthesia (TA). But dilemma exists regarding the supremacy of one over the other as both types have certain advantages and disadvantages.Methods: A prospective study was conducted. Patients were divided into two groups. Group-1 underwent PA while group-2 underwent TA. Satisfaction score of patients and surgeons and incidence of complications were noted. The data was analyzed.Results: Lowest patients’ satisfaction score among group-1 vs. group-2 was 160 (87.9%) vs.82 (45.81%). Highest surgeons satisfaction score among group-1 and group-2 was 74(40.65%) vs. 2(1.1%). Intraoperative complications among the group-1 and group-2 were 35 (19.2%) vs. 86(48.0%).Conclusions: While TA provides initial painless phase of surgical procedure, PA results in lesser intraoperative complications resulting in better visual outcome.
