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.

Effects of topical nonsteroidal antiinflammatory drugs on the expression of matrix metalloproteinases in the cornea.
To assess the effects of nonsteroidal antiinflammatory drug (NSAID) eyedrops on the expression of matrix metalloproteinases in corneal tissue. ⋯ This study provides preliminary evidence that topical application of some NSAIDs can induce the early expression of MMP-1, MMP-2, and MMP-8 in the cornea, suggesting that MMPs play a role in the corneal cytotoxicity of certain NSAIDs.

Case ReportsManagement of bilateral anterior dislocation of a lens in a child with Marfan's syndrome.
A 13-year-old boy with Marfan's syndrome presented with bilateral, acute, complete anterior dislocation of the crystalline lens. The lens substance was aspirated intracapsularly after 2 linear capsulotomies were created. ⋯ Aphakia was corrected by glasses and contact lenses. Two years after surgery, the best corrected visual acuity was 20/32 in both eyes.

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.
