Randomized Controlled Trial Clinical Trial
An analysis of risk for secondary hemorrhage in traumatic hyphema.
Factors such as size of hyphema, intraocular pressure, initial visual acuity, and use of steroids or antifibrinolytic drugs may be associated with the likelihood of rebleeding in traumatic hyphema. The association of the visual outcome with secondary hemorrhage has been questioned. ⋯ High intraocular pressure and low vision at the time of first examination may be associated with increased chance of rebleeding. Retinal damage, secondary hemorrhage, male gender, and initial poor vision are associated with a worse visual outcome in patients with traumatic hyphema.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of patient comfort during cataract surgery with topical anesthesia versus topical anesthesia and intracameral lidocaine.
To determine whether intraocular lidocaine increases patient comfort during cataract surgery while under topical anesthesia. ⋯ Both topical anesthesia alone and topical anesthesia plus intracameral lidocaine provide good operative conditions for the surgeon and comfortable surgical circumstances for the patient. Injection of intraocular lidocaine increases patient cooperation and decreases the degree to which patients are bothered by tissue manipulation, two outcomes that justify its use.

Randomized Controlled Trial Comparative Study Clinical Trial
A randomized clinical trial of combined topical-intracameral anesthesia in cataract surgery.
To evaluate the level of patient discomfort during phacoemulsification and implantation of a foldable intraocular lens (IOL) while under topical lidocaine, alone or in combination with intracameral lidocaine. ⋯ Although topical lidocaine alone provides adequate anesthesia for phacoemulsification and implantation of a foldable IOL, combined topical and intracameral administration of lidocaine can further minimize intraoperative discomfort.

Randomized Controlled Trial Clinical Trial
A study of topical nonsteroidal anti-inflammatory drops and no pressure patching in the treatment of corneal abrasions. Corneal Abrasion Patching Study Group.
To evaluate the effectiveness of an ophthalmic nonsteroidal anti-inflammatory drug (NSAID) in the treatment of noninfected, non-contact lens-related, traumatic corneal abrasions and no pressure patch. ⋯ Ketorolac tromethamine 0.5% ophthalmic solution provides increased patient comfort without clinical adverse effects when used as adjunctive therapy in the treatment of noninfected, non-contact lens-related, traumatic corneal abrasions.

Randomized Controlled Trial Clinical Trial
Dilute topical proparacaine for pain relief after photorefractive keratectomy.
The purpose of the study is to determine whether there is a nonanesthetic and nontoxic concentration of topical proparacaine that can be applied repeatedly to the cornea to reduce pain after photorefractive keratectomy (PRK). ⋯ Dilute (0.05%) topical proparacaine is nonanesthetic and nontoxic, and can be used safely for at least 1 week to reduce pain after PRK.
