Randomized Controlled Trial Comparative Study
Big-bubble deep anterior lamellar keratoplasty using central vs peripheral air injection: a clinical trial.
To compare 2 sites of air injection to achieve Descemet membrane (DM) detachment in big-bubble deep anterior lamellar keratoplasty (DALK). ⋯ Both injection sites were equivalent in their rates of big-bubble formation and complications. Less experienced surgeons are advised to initially inject air outside the trephination.

Retrobulbar dexmedetomidine decreases the MLAC of ropivacaine in vitreoretinal surgery in children.
Dexmedetomidine can prolong the duration of local anesthetics, but the effect of retrobulbar dexmedetomidine on the potency of ropivacaine for retrobulbar block has not been investigated. Our study was designed to determine the effect of retrobulbar dexmedetomidine on ropivacaine for retrobulbar block in children. ⋯ Retrobulbar dexmedetomidine reduces the MLAC values of ropivacaine and improves postoperative analgesia in children without any neurologic side effects.

A comprehensive clinical study about patching after strabismus surgery.
Patching of the operative eye is occasionally used in pediatric strabismus surgery. The primary purpose of this study was to investigate the psychological and physiologic effects of patching after operation by multifactorial methods. ⋯ Patching is not necessary for reducing postoperative pain or the risk of infection in children undergoing strabismus surgery.

Randomized Controlled Trial
Evaluation of the efficacy and safety of the ophthalmic insert Mydriasert in patients undergoing retinal angiography.
To verify the efficacy to obtain mydriasis and cardiovascular safety of Mydriasert (ophthalmic insert containing tropicamide and phenylephrine) in diabetic and nondiabetic patients undergoing retinal angiography by comparing it with usually administered eyedrops (tropicamide 1% and phenylephrine 10%). ⋯ Mydriasert assures an adequate degree of mydriasis for retinal angiography in both diabetic and nondiabetic patients. There are no differences in efficacy or safety between the insert and the usually administered eyedrops, but the low total drug dose administered with the insert reduces the risk of cardiovascular side effects.

Randomized Controlled Trial Comparative Study
Sub-Tenon block does not provide superior postoperative analgesia vs intravenous fentanyl in pediatric squint surgery.
We evaluated the efficacy of sub-Tenon block in decreasing perioperative pain, incidence of intraoperative oculocardiac reflex (OCR), and postoperative nausea and vomiting (PONV) in pediatric squint surgery. ⋯ Use of sub-Tenon block does not decrease the incidence of postoperative pain significantly in children undergoing squint surgery. However, it leads to a statistically significant decrease in the incidence of intraoperative OCR and PONV in the early recovery period in these patients.
