Randomized Controlled Trial Comparative Study Clinical TrialRopivacaine-lidocaine versus bupivacaine-lidocaine for retrobulbar anesthesia in cataract surgery.
To compare the efficacy of ropivacaine mixed with lidocaine and bupivacaine mixed with lidocaine for retrobulbar anesthesia in cataract surgery. ⋯ Ropivacaine mixed with lidocaine and bupivacaine mixed with lidocaine were equally effective in producing ocular analgesia and akinesia for ECCE.

Case ReportsInadvertent ocular perforation and intravitreal injection of an anesthetic agent during retrobulbar injection.
We report the clinical management of a patient who sustained scleral perforation and intraocular injection of local anesthetic agent during retrobulbar block. We discuss the management options for this rare complication of local anesthesia in cataract surgery.

Big-bubble technique to bare Descemet's membrane in anterior lamellar keratoplasty.
We describe a lamellar keratoplasty technique to bare Descemet's membrane in which air is injected to detach the central Descemet's. After a partial-thickness corneal trephination is performed, a disposable needle is inserted, deeply and bevel down, into the paracentral corneal stroma and air is injected. ⋯ After anterior lamellar keratectomy is performed, a small opening is made in the air bubble and the remaining stromal layers are lifted with an iris spatula, severed with a blade, and excised with scissors. This technique is faster, safer, and easier to perform than previous methods.

We present the first reported case of traumatic aniridia as an isolated injury after blunt trauma to an eye that had phacoemulsification through a corneal tunnel. This case provides insight into the properties of the self-sealing corneal tunnel and possible advantages that it may confer on the eye.

Randomized Controlled Trial Comparative Study Clinical TrialRole of the bandage soft contact lens in the postoperative laser in situ keratomileusis patient.
To determine whether a bandage soft contact lens (BSCL) is routinely needed in the postoperative laser in situ keratomileusis (LASIK) patient and whether topical tetracaine 0.5% or diclofenac sodium 0.1% (Voltaren) is more effective in relieving patient discomfort than a BSCL. ⋯ The routine use of a BSCL in the postoperative LASIK patient is not necessary. Voltaren and tetracaine 0.5% were safe and more effective in relieving postoperative patient discomfort and resulted in improved visual acuity immediately postoperatively.
