Case ReportsRupture of anterior lens capsule from blunt ocular injury.
We report 3 cases of blunt trauma causing rupture of the anterior lens capsule with cataract formation. The injuries were caused by a paintball gun, a ball-bearing air pistol, and an aluminum rivet. ⋯ The postoperative visual acuities was 20/40 in 1 case and 20/20 in the other 2 cases. We propose that the anterior lens capsule may have been torn by direct contusion from rapid focal indentation of the cornea onto the lens (coup injury) or by a fluid-mechanical, anteriorly directed rebound of the vitreous, bursting open the anterior capsule (contrecoup injury).

Case ReportsArgon laser iridotomy as a possible cause of anterior dislocation of a crystalline lens.
We report a case of spontaneous dislocation of the crystalline lens into the anterior chamber in a patient with no history of trauma or any systemic disease associated with zonular dialysis. Anterior lens dislocation developed 10 months after argon laser iridotomy had been performed for angle-closure glaucoma. We suspect the argon laser iridotomy might have induced localized zonular dialysis that resulted in progressive zonular weakness and, finally, lens dislocation into the anterior chamber.

Case ReportsAnesthetic keratopathy after photorefractive keratectomy.
We report a case of anesthetic keratopathy after photorefractive keratectomy (PRK) and physician-prescribed topical anesthetic agents. After PRK for hyperopic correction, the patient was sent home with a bandage contact lens and instructions to use anesthetic eyedrops and take oral pain medications after surgery. During the first postoperative week, the eyes did not reepithelialize and bilateral perilimbal infiltrates developed. ⋯ She was instructed to stop the anesthetic agent labeled as "comfort drops" and the fortified antibiotics and start topical steroids. Soon after, the eyes reepithelialized and the infiltrates cleared. This case demonstrates the potential for anesthetic keratopathy in PRK patients.

Randomized Controlled Trial Multicenter StudyEfficacy of topical plus intracameral anesthesia for cataract surgery in high myopia: randomized controlled trial.
To assess the efficacy of intracameral lidocaine supplementation of topical anesthesia during cataract surgery in eyes with high myopia. ⋯ Intracameral lidocaine supplementation for cataract surgery may improve intraoperative comfort under topical anesthesia in highly myopic eyes.

Visual acuity tolerance to residual refractive errors in patients with an apodized diffractive intraocular lens.
To assess visual acuity tolerance to defocus caused by residual refractive errors after clear lens extraction (CLE) with apodized diffractive intraocular lens (IOL) implantation. ⋯ Correction of distance residual refractive error improved distance visual acuity in patients with apodized diffractive IOLs. However, near visual acuity was maintained whether the residual refractive error was corrected or not.
