“…In studies examining the anesthetic effect of lidocaine gel 2% alone, the mean pain score ranged between 0.72 and 2.22 [7, 11, 12]. The results presented in our study give an excellent mean pain score of 0.18 for lidocaine gel combined with intracameral lidocaine.…”

Purpose: To assess the safety and efficacy of two topical anesthesia regimes for cataract surgery. Methods: 21 patients received a combination of 4 times bupivacaine 0.5, oxybuprocaine and diclofenac eyedrops, 18 patients were given a single topical application of lidocaine gel 2%. A single intracameral injection of lidocaine 1% was administered to all subjects. Results: The extent to which the surgeon was bothered by patient motility was graded as low in about two thirds of all procedures. Patients reported lower intraoperative pain levels with a single application of lidocaine gel supplemented with intracameral lidocaine than with a fourfold application of the combination topical anesthesia plus intracameral anesthesia. Conclusions: A single application of lidocaine gel 2% combined with intracameral anesthesia provides at least as good analgesia than multiple administration of combined topical anesthesia supplemented with intracameral anesthesia and is equally safe.

“…Conversely, Chalam et al, found that the 0.5% tetracaine eye drop was more superior that the 2% lidocaine gel (5). In general, both anesthetic agents were equally effective as analgesia for cataract phacoemulsification surgery (6). …”

“…Chalam et al, mentioned the superiority of 0.5% tetracaine eye drop during intraoperative pain management in comparison with 2% lidocaine gel (5). However, another study mentioned that 0.5% tetracaine eye drop must be administered at least three times to achive the desired effect (6). …”

BackgroundTopical anesthetics have become the primary choice in phacoemulsification procedures for cataract extraction. The most common topical anesthetic drug used is 0.5% tetracaine eye drops. Repeated administration of 0.5% tetracaine drops can cause corneal epithelial damage. Two percent lidocaine gel is latest option which has longer contact time with corneal epithelium.ObjectivesTo compare the effectiveness of 2% lidocaine gel with 0.5% tetracaine drops in phacoemulsification surgery.MethodsThe study was a single blinded randomized clinical trial from March to July 2017 in patients underwent phacoemulsification cataract surgery. There were 72 subjects with age ≥ 40 years old who received randomization and divided into 2 groups: 2% lidocaine gel group and 0.5% tetracaine eye drop group. Topical anesthetics were applied 5 minutes before surgery. Five minutes after surgery, pain scale perceived during surgery was assessed by using a numerical rating scale. At the end of surgery, the subject filled the satisfaction questionnaire on topical anesthetic drugs administered. The ophthalmologists were also given a satisfactory questionnaire for topical anesthetic drugs selected for the procedure.ResultsThe median pain scale for 2% lidocaine gel group pain scale was 1; meanwhile, the median pain scale for 0.5% tetracaine eye drops was 3 (P < 0.05).ConclusionsTwo percent lidocaine gel was more effective in relieving pain during phacoemulsification cataract surgery compared with 0.5% tetracaine drops.

“…These studies were limited by the absence of standardization in the quality of pain reported by the patients, because no validated pain assessment tool such as the VAS was used. On the other hand, studies like the one by Irle et al18 showed that the effect of instillation of tetracaine 0.5% eyedrops is better than that of lidocaine 2% gel application during cataract surgery, but leaving unanswered questions about the ideal method of topical anesthesia.…”

Background and objective:To evaluate the level of pain during phacoemulsification and foldable intraocular lens implantation under instillation of tetracaine 0.5% eyedrops versus a combination of lidocaine 2% gel and instillation of tetracaine eyedrops.Methods:This prospective, randomized, controlled study included 51 patients undergoing phacoemulsification under topical anesthesia. They were randomized into two groups based on the topical anesthetic method they were to receive. Preoperatively all patients were asked to answer a questionnaire. One hour postoperatively, they were asked to grade their intraoperative and postoperative pain on a visual analog scale from 0 to 10.Results:There were no statistically significant differences between the two methods of anesthesia. Gender and the presence of relatives or friends were independent factors playing a significant role in pain sensitivity.Conclusions:The combination of lidocaine 2% gel and tetracaine eyedrops does not have a better analgesic result than a single instillation of tetracaine 0.5% eyedrops.

Vergleichende Verlaufsbeobachtung der Tetracaintropfanästhesie gegen Lidocaingelanästhesie bei der Kataraktoperation

Abstract: Both gel anaesthesia and drop anaesthesia are suitable methods for cataract surgery under local anaesthesia. According to patients' assessment, drop anaesthesia with tetracaine is better suited for pain elimination.
