Randomized Controlled Trial Clinical TrialIntracameral mydriatics in phacoemulsification cataract surgery.
To evaluate intracameral injection of mydriatics in phacoemulsification cataract surgery and compare the results with those of conventional topical mydriatics. ⋯ Intracameral mydriatics were a rapid, effective, and safe alternative to topical mydriatics in phacoemulsification. Their use can simplify preoperative routines and in certain high-risk groups, may reduce the risk for cardiovascular side effects.

Case ReportsRetained contact lens for more than 10 years in a laser in situ keratomileusis patient.
A 49-year-old man with blurred vision in 1 eye and myopic regression had laser in situ keratomileusis (LASIK) in the right eye after having 20/20 uncorrected visual acuity for 2 years. At the conclusion of surgery, a poly(methyl methacrylate) contact lens that had been retained for more than 10 years was discovered in the upper fornix. ⋯ In addition, retained contact lenses, lid lesions, and periocular masses can induce refractive and topographic changes after LASIK. The retained contact lens may have led to compression-induced changes in corneal curvature, resulting in the need for uniocular enhancement 2 years after the primary LASIK procedure.

Randomized Controlled Trial Comparative Study Clinical TrialLaser-assisted subepithelial keratectomy and photorefractive keratectomy for the correction of hyperopia. Results of a 2-year follow-up.
To evaluate and compare the efficacy, safety, predictability, and stability of laser-assisted subepithelial keratectomy (LASEK) and photorefractive keratectomy (PRK) for low to moderate hyperopia with a 2-year follow-up. ⋯ Laser-assisted subepithelial keratectomy for hyperopia up to +5.00 D provided good visual and refractive results. It significantly reduced postoperative pain, grade of peripheral ring-shaped corneal haze, and regression of hyperopia. Hyperopic LASEK provided quicker visual recovery and achieved better efficacy, predictability, and refractive stability than hyperopic PRK.

Randomized Controlled Trial Comparative Study Clinical TrialClorazepate dipotassium versus midazolam for premedication in clear corneal cataract surgery.
To evaluate and compare the efficacy of oral clorazepate dipotassium (Tranxilium) and intravenous midazolam (Dormicum) as premedication agents in retrobulbar anesthesia and clear corneal phacoemulsification with intraocular lens (IOL) implantation. ⋯ Anterograde amnesia occurred more frequently and patients expected less pain before surgery with midazolam. Both anesthetic agents provided safe and effective premedication for retrobulbar anesthesia in clear corneal cataract surgery.
