Randomized Controlled Trial
Pain relief after pterygium surgery with viscous lidocaine.
The aim of the current study is to investigate the efficacy of lidocaine 2% gel for the control of pain experienced after pterygium surgery. ⋯ We conclude that topical lidocaine gel is an effective and safe anesthetic agent for the control of pain experienced shortly after pterygium surgery.

Randomized Controlled Trial Comparative Study Clinical Trial
Lidocaine gel versus combined topical anesthesia using bupivacaine, oxybuprocaine and diclofenac eyedrops in cataract surgery.
To assess the safety and efficacy of two topical anesthesia regimes for cataract surgery. ⋯ 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.

Collagen cross-linking using combined riboflavin/UVA treatment has been shown to increase the biomechanical rigidity of the cornea and has been used successfully for the treatment of progressive keratoconus. From morphological and biochemical investigations, a different degree of cross-linking for the anterior and posterior stroma by the treatment is suggested. The present study was undertaken to better evaluate this effect by testing the thermomechanical behavior. ⋯ The different degree of collagen cross-linking in the corneal stroma after riboflavin/UVA treatment is reflected by the differences in the maximal shrinkage temperature of the anterior and posterior portion. Therefore, in the corneas cross-linked with riboflavin/UVA a higher shrinkage temperature was observed for the anterior portion of the cornea (75 degrees C) compared to the posterior stroma (70 degrees C) due to the higher degree of cross-linking of the anterior stroma. The anterior localization of the cross-linking effect is advantageous for the endothelium and for the preservation of the anterior corneal curvature.

Randomized Controlled Trial Comparative Study Clinical Trial
Treatment of vomiting after paediatric strabismus surgery with granisetron, droperidol, and metoclopramide.
We have compared the efficacy and safety of granisetron, droperidol, and metoclopramide in the treatment of postoperative vomiting (POV) in children scheduled for strabismus surgery. After experiencing POV during the first 3 h after recovery from anaesthesia, 120 patients received intravenously, in a randomized, double-blind manner, granisetron 40 microg/kg, droperidol 50 microg/kg, or metoclopramide 0.25 mg/kg (n = 40 in each group). ⋯ No clinically serious adverse events were observed in any group. In conclusion, granisetron is more effective than droperidol or metoclopramide in the treatment of POV after paediatric strabismus surgery.

Randomized Controlled Trial Comparative Study Clinical Trial
Use of piritramide for analgesia and sedation during peribulbar nerve block for cataract surgery.
To investigate the effects of pre-block analgesia and sedation using piritramide on haemodynamic stability, endocrine stress response and patients' pain perception. ⋯ The presented study suggests that using piritramide for analgesia and sedation prior to peribulbar block produces haemodynamic stability and reduces pain perception and endocrine stress response.
