AIM: To evaluate safety, efficacy, and patient adherence of intracameral lidocaine as supplement of classic topical anesthetic drops in cataract surgery.
METHODS: A prospective and controlled trial including a large cohort of 1650 individuals suffering with bilateral cataract not complicated, in program by phacoemulsification surgery, were randomly assigned to 2 different groups for the type of anesthesia received, 0.4% oxybuprocaine hydrochloride (INN) drops, and INN drops associated to intracameral 1% lidocaine hydrochloride monohydrate. At the end of surgery, tables were assigned to each patient indicating the degree of pain (0-3) felt during the operation.
RESULTS: Thirty-two percent of patients in group 1 declared to have not felt any pain against the 77% of patients in group 2. Fifty-nine percent of patients in group 1 complained about only a slight discomfort against 20% of group 2 patients. Only a small percentage of patients in group 1 (5%) admitted severe pain, while no patient in group 2 admitted severe pain. Four patients of group 2 reported an episode of transient amaurosis, lasting several hours after surgery.
CONCLUSION: Intracameral administration of lidocaine is a simple and secure method able to increase the analgesia during the cataract surgery, eliminating the discomfort and increasing also the cooperation of the patients during the steps of manipulation. 相似文献

PURPOSE: To compare pain control using topical anesthesia with that using sub-Tenon's anesthesia for clear corneal phacoemulsification cataract surgery and foldable intraocular lens (IOL) implantation. SETTING: Departments of Ophthalmology, General Hospital Asklepeion Voulas and General Hospital of Athens, University of Athens, Athens, Greece. METHODS: One hundred consecutive patients scheduled for bilateral cataract surgery 1 to 2 months apart were prospectively randomized to receive topical anesthesia (100 eyes) or sub-Tenon's anesthesia (100 eyes). The randomization was stratified so that one half of first-eye surgeries and one half of second-eye surgeries were assigned to each anesthesia group, with each patient receiving each type of anesthesia once. All patients had clear corneal phacoemulsification with foldable IOL implantation. Patients were asked to rate their pain level on a 10-point scale for 4 periods: during the administration of the anesthetic agent, during surgery, immediately after surgery, and 24 hours postoperatively. The surgeon recorded his subjective assessment of ease of surgery and surgical complications using a standardized template. RESULTS: Eighty-one percent of patients who received topical anesthesia and 8% of patients who received sub-Tenon's anesthesia reported no pain during delivery of the anesthetic agent. The mean pain score was 0.19 +/- 0.39 (SD) in the topical group and 1.35 +/- 0.63 in the sub-Tenon's group. The difference between groups was statistically significant (P <.001). Seventy-two percent of patients in the topical anesthesia group and 86% in the sub-Tenon's anesthesia group reported no pain or slight discomfort during surgery (mean score 1.13 +/- 1.57 and 0.57 +/- 1.28, respectively) (P <.001). Ninety percent of topical anesthesia patients and 100% of sub-Tenon's anesthesia patients reported no pain or slight discomfort 30 minutes postoperatively (mean score 0.80 +/- 0.93 and 0.12 +/- 036, respectively) (P <.001). All patients in the topical anesthesia group and 77% in the sub-Tenon's group reported no pain 24 hours postoperatively (mean pain 0.00 +/- 0.00 and 0.23 +/- 0.40, respectively) (P <.001). Complications including prolonged akinesia of the globe, chemosis, and conjunctival hemorrhage occurred significantly more frequently in the sub-Tenon's than in the topical group (P <.001). CONCLUSIONS: Patients having cataract surgery under topical anesthesia had more intraoperative and postoperative discomfort than patients receiving sub-Tenon's anesthesia. However, patients having topical anesthesia reported less pain during its administration and had fewer complications. Both anesthesia methods provided high levels of pain control without additional sedation. 相似文献

Purpose: To compare the intraoperative pain scores during clear corneal phacoemulsification under no anesthesia, topical anesthesia, and topical plus intracameral anesthesia.Setting: Dr. Agarwal's Eye Hospital and Eye Research Center, Chennai, India.Methods: Seventy-five patients were randomized to have phacoemulsification under no anesthesia, topical anesthesia, or topical plus intracameral anesthesia. Uncooperative or illiterate patients and those with hard cataract, a shallow anterior chamber, or small pupils were excluded. A protocol was established for supplemental anesthesia in case of breakthrough pain during the surgery. Each patient was asked to grade the overall severity of intraoperative pain immediately after surgery on a 10-point visual analog scale. Also evaluated were the general discomfort during surgery, discomfort from the microscope lights, surgeon stress during surgery, and total surgical time. Comparison among the 3 groups was performed using an analysis of variance.Results: No supplemental anesthesia was required in any group. No significant difference was noted in the mean scores of the subjective sensation of pain with or without topical anesthesia (P =.610). The mean scores of patient discomfort from the microscope lights and surgical time were also statistically insignificant. Patient discomfort and surgeon stress during surgery were significantly greater in the no-anesthesia group than in the topical and topical plus intracameral groups (P =.0235 and P = 0.0206, respectively).Conclusion: No-anesthesia clear corneal phacoemulsification was performed by a highly experienced, skilled surgeon without causing an unacceptable level of pain. However, this technique is not suitable for every cataract surgeon or patient. 相似文献

Topical anesthesia for phacoemulsification, intraocular lens implantation, and posterior vitrectomy.
J Yepez J Cedeno de Yepez J F Arevalo 《Journal of cataract and refractive surgery》1999,25(8):1161-1164
PURPOSE: To evaluate the efficacy of topical anesthesia as an alternative to peribulbar or retrobulbar anesthesia in phacoemulsification and intraocular lens (IOL) implantation combined with pars plana vitrectomy. SETTING: Clinica de Ojos de Maracaibo, Maracaibo, and the Retina and Vitreous Service, Clinica Oftalmologica Centro Caracas, Caracas, Venezuela. METHODS: In this prospective study, phacoemulsification, IOL implantation, and posterior vitrectomy using topical anesthesia (lidocaine 4% drops) were prospectively performed in 45 eyes (45 patients) with varied vitreoretinal pathology including macular holes, epiretinal membranes, subfoveal neovascular membranes, proliferative diabetic retinopathy, and vitreous hemorrhage. Preoperative and intraoperative sedation of varying degrees was necessary. Subjective pain and discomfort were graded from 1 (no pain or discomfort) to 4 (severe pain and discomfort). RESULTS: All patients had grade 1 pain and discomfort during most of the procedure. All patients had grade 2 (mild) pain and discomfort during pars plana sclerotomies, external bipolar cautery, and conjunctival closure. The mean amount of lidocaine 4% drops required during each procedure was 0.5 mL. No patient required additional retrobulbar, peribulbar, or sub-Tenon's anesthesia. CONCLUSIONS: This technique avoids the risks of globe perforation, retrobulbar hemorrhage, and prolonged postoperative akinesia of the eye at a lower cost. With appropriate case selection, topical anesthesia was a safe and effective alternative to peribulbar or retrobulbar anesthesia in phacoemulsification and IOL implantation combined with posterior 3-port pars plana vitrectomy. 相似文献

PURPOSE: To evaluate the use of a mixture of hydroxypropyl methylcellulose 2.25% (HPMC) and lidocaine 1% (final concentrations) as a single viscoelastic/anesthetic agent to achieve proper anesthesia and viscoelastic properties during phacoemulsification. SETTINGS: Department of Ophthalmology, Cairo University, Cairo, Egypt. METHODS: This prospective randomized study comprised 70 eyes having routine phacoemulsification. Patients had the HPMC-lidocaine mixture (n = 35) or pure HPMC 2.25% (n = 35) injected before capsulorhexis and again before intraocular lens implantation. The results were evaluated by a pain/discomfort score postoperatively. RESULTS: The difference in medians of the overall intraoperative pain/discomfort scores between the 2 groups was not statistically significant. However, mild pain/discomfort was reported by 60.0% in the pure HPMC group and by 31.4% in the HPMC-lidocaine mixture group. Moderate pain/discomfort was reported by 28.6% and 5.7%, respectively. The difference between the 2 groups was statistically significant (P =.001). CONCLUSION: The use of a mixture of HPMC 2.25% and lidocaine 1% rather than a regular viscoelastic agent resulted in clinically and statistically significantly reduced pain/discomfort during phacoemulsification. 相似文献

PURPOSE: To assess the pain experienced by patients with small pupils during pupil stretching in phacoemulsification performed using topical anesthesia. SETTING: Royal Victoria Eye & Ear Hospital and Mater Misericordiae University Hospital, Dublin, Ireland. METHODS: This was a prospective study that included 26 eyes with small pupils requiring mechanical pupil stretching during phacoemulsification cataract surgery performed under topical anesthesia without sedation. RESULTS: The mean pain score for the instillation of anesthetic drops (2.02) was higher than the mean pain score for the pupil stretch (1.63), but this difference was not significant (signed rank test = -32; P = .2738). There was no significant correlation between the duration of surgery and the overall pain score (r = 0.345; P = .08). There was no significant correlation between change in pupil size and either the pupil stretch score (r = -0.069; P = .74) or the overall pain score (r = -0.032; P = .8739). CONCLUSIONS: Pupil stretching during phacoemulsification in patients with small pupils was performed with minimal patient-reported pain using topical anesthesia. Stretching small pupils with a mechanical device during phacoemulsification performed under topical anesthesia was a safe procedure and did not result in significant patient discomfort. 相似文献

BACKGROUND AND OBJECTIVE: To evaluate the efficacy of topical anesthesia as an alternative to peribulbar or retrobulbar anesthesia in phacoemulsification and intraocular lens implantation combined with our modified 2-port pars plana vitrectomy technique (phacovitrectomy). PATIENTS AND METHODS: Phacovitrectomy using topical anesthesia (4% lidocaine drops) was prospectively performed in 105 eyes with cataract and varied vitreoretinal pathology. In 75 eyes (71.4%), phacovitrectomy was combined with argon laser photocoagulation (endolaser). Preoperative and intraoperative sedation of varying degrees was necessary. Subjective pain and discomfort were graded from 1 (no pain or discomfort) to 4 (severe pain and discomfort). RESULTS: All patients had grade 1 pain and discomfort during most of the procedure. All patients had grade 2 (mild) pain and discomfort during pars plana sclerotomies, external bipolar cautery, and conjunctival closure. No patient required additional retrobulbar, peribulbar, or sub-Tenon's anesthesia. CONCLUSION: This technique avoids the risk of globe perforation, retrobulbar hemorrhage, and prolonged postoperative akinesia of the eye. With appropriate case selection, topical anesthesia is a safe and effective alternative to peribulbar or retrobulbar anesthesia in phacovitrectomy. 相似文献
