Randomized Controlled Trial Comparative Study Clinical Trial
Corneal sensation after topical anesthesia.
To compare the topical effects of tetracaine, lidocaine, and bupivacaine on corneal sensitivity in normal eyes. ⋯ The application of 4% lidocaine results in a significantly prolonged topical anesthetic effect when compared with tetracaine and bupivacaine.

To determine the leading indications for penetrating keratoplasty and to identify changing trends in these indications during the past 12 years. ⋯ In this series, corneal scars, regraft, and acute necrotizing and ulcerative keratitis were the leading indications for penetrating keratoplasty. A changing incidence of pseudophakic and aphakic bullous keratopathy noted during the study period was related to the type of intraocular lens implanted and the method of cataract surgery performed. This study found a comparatively high frequency of acute necrotizing and ulcerative keratitis and an extremely low frequency of keratoconus compared with previous reports.

To describe a case of successful treatment of a corneal perforation with 2-octyl cyanoacrylate. ⋯ We have described a case in which 2-octyl cyanoacrylate was used to treat a corneal perforation with excellent results. Further study of this adhesive will be useful in comparing the effectiveness and safety of 2-octyl cyanoacrylate with that of previously studied adhesives.
