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.

Randomized Controlled Trial Clinical TrialEffects of fentanyl on pain and hemodynamic response after retrobulbar block in patients having phacoemulsification.
To determine the effects of systemic fentanyl analgesia in preventing the pain related to the administration of retrobulbar anesthesia and cataract surgery. ⋯ The results suggest that fentanyl preemptively decreases injection and intraoperative hyperalgesia and provides hemodynamic stability without affecting patient cooperation, resulting in cataract surgery with retrobulbar anesthesia that is comfortable for both surgeon and patient.

Randomized Controlled Trial Clinical TrialPreventing intraocular pressure increase after phacoemulsification and the role of perioperative apraclonidine.
To evaluate the effectiveness of prophylactic topical apraclonidine 1% in preventing an intraocular pressure (IOP) rise in the early period after uneventful phacoemulsification with intraocular lens (IOL) implantation. ⋯ Prophylactic topical perioperative apraclonidine 1% did not cause a significant reduction in the postoperative IOP when compared with a control group.

Randomized Controlled Trial Clinical TrialPatient-controlled analgesia and sedation with fentanyl in phacoemulsification under topical anesthesia.
To investigate the effects of intravenous (IV) patient-controlled sedation/analgesia with fentanyl during phacoemulsification surgery under topical anesthesia. ⋯ The results of this study suggest that IV PCA with fentanyl has supplemental effects on analgesia and sedation during cataract surgery under topical anesthesia and increases patient comfort and surgeon satisfaction.
