Variant of the big bubble technique in deep anterior lamellar keratoplasty.
We describe a variant of the big-bubble technique that involves placement of a stromal corneal nick and nontraumatic intrastromal insertion of a blunt cannula following anterior lamellar keratectomy. The goal of this technique is to reduce the risk for intraoperative corneal perforation and to obtain a large air bubble between Descemet's membrane and the corneal stroma. Deep anterior lamellar keratoplasty is easier and safer with this technique.

Randomized Controlled TrialSafety and efficacy of topical anesthesia combined with a lower concentration of intracameral lidocaine in phacoemulsification: paired human eye study.
To assess the safety and efficacy of phacoemulsification under a topical anesthesia combined with intracameral lidocaine 0.5%. ⋯ Combining topical anesthesia with intracameral lidocaine 0.5% [corrected] anesthesia was safe and effective in phacoemulsification with intraocular lens implantation.

Randomized Controlled Trial Comparative StudyTetracaine hydrochloride 0.5% versus lidocaine 2% jelly as a topical anesthetic agent in cataract surgery: comparative clinical trial.
To assess the anesthetic efficacy of tetracaine hydrochloride 0.5% (TetraVisc) versus lidocaine 2% jelly in routine cataract extraction. ⋯ TetraVisc was as effective as lidocaine 2% jelly as a topical anesthetic agent for routine cataract extraction.

Comparative StudyPupil dilation with intracameral lidocaine during phacoemulsification.
To evaluate pupil dilation by an intracameral injection of nonpreserved lidocaine 1% during phacoemulsification cataract extraction and compare the results with those using conventional topical mydriatics. ⋯ During phacoemulsification, intracameral preservative-free lidocaine 1% provided rapid, effective mydriasis comparable that of topical mydriatics.
