“…The purpose was to avoid the additional step of irrigating the anterior chamber with lidocaine solution, and to prolong anaesthesia time to cover little delays in the completion of surgery. One system is based on methylcellulose [35], while a second system is based on sodium hyaluronate [76]. This system is commercially available in some countries and includes a prepared syringe with viscoanaesthetic mixture and two ampoules of jelly eyedrops to be applied before surgery to minimise corneal epithelial toxicity.…”

“…Available data collected on experimental settings indicates viscoanaesthesia is safe for corneal endothelium [76], with no evidence of any postoperative reaction after phacoemulsification [50], and no impairment of the mechanical properties of the viscoelastic device [63]. Early clinical data indicates good efficacy [35].…”

In the past few years, there have been many changes in ophthalmic anaesthesia. Application of drugs in general anaesthesia with excellent controllability enhances patient safety and allows a more efficient OR-management. Regional anaesthesia is gaining widespread use for ophthalmic surgery, especially topical anaesthesia for cataract surgery. Patients for ophthalmic surgery concomitantly often display high age and a high level of co-morbidity and, therefore, belong to the anaesthesiological risk groups ASA III-IV. Life-threatening adverse events including cardiovascular depression are associated with general and regional anaesthesia. Intervention by anaesthesiologists is frequently required for treatment of hypertension or dysrhythmias, and sedation. Thus, monitored anaesthesia care ("standby") is justified. Drugs applied for regional and general anaesthesia may change intraocular pressure. There are a lot of publications about the impact of anaesthesia on intraocular pressure (IOD), however, few on the effects of anaesthesia on pulsatile ocular blood flow. it has to be kept in mind that the effects of anaesthesia on intra-ocular pressure and pulsatile ocular blood flow may diverge. To avoid an increase of the IOD, especially during anaesthesia induction, drugs, such as succinylcholin, rocuronium and opiates, in particular remifentanil, can be applied. In addition, the use of the laryngeal mask may be advantageous compared to general anaesthesia associated with laryngoscopic tracheal intubation. The management of patients treated with anticoagulants and antiplatelet agents, has to be taken on the balance of risks. There are risks not only in continuing therapy, but also in discontinuing it perioperatively. Postoperative nausea and vomiting (PONV) remains a distressing and common problem after strabismus repair in particular in children. The incidence of PONV depends on the type of ophthalmic surgery and drugs applied. To reduce PONV in ophthalmic surgery, application of long-lasting opiates should be avoided, and non-opiate analgesics and, depending on the kind of operation, antiemetic prophylactics are recommended.

Combined lidocaine 1% and hydroxypropyl methylcellulose 2.25% as a single anesthetic/ viscoelastic agent in phacoemulsification

Abstract: 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.
