Effects of preoperative doses of betamethasone acetate 0.1% on dry eye control after cataract surgery.

Purpose: The aim of the present study was to compare the effects of the preoperative doses of betamethasone acetate 0.1% and placebo on controlling dry eye after cataract surgery.

Methods: This randomized triple-blind clinical trial was conducted on 62 patients.

Photorefractive keratectomy in mild to moderate keratoconus: outcomes in over 40-year-old patients.

Background: Keratoconus is a contraindication for photorefractive keratectomy (PRK). In the recent decade, some efforts have been made to perform PRK in patients with keratoconus whose corneas are stable naturally or by doing corneal collagen crosslinking. These studies have suggested residual central corneal thickness (CCT) ≥450 μm.

Use of angle kappa in myopic photorefractive keratectomy.

Purpose: To explore utilization of the coaxially sighted corneal light reflex (CSCLR) for centration during myopic photorefractive keratectomy (PRK) for patients with relatively high angle kappa (κ) values.

Methods: Patients were stratified into two groups preoperatively, on the basis of angle κ values. Group A was composed of 166 eyes with an angle κ value <5°.

Partial and Total Descemet's Detachments in a Patient with Severe Terrien's Marginal Degeneration and Juvenile Idiopathic Arthritis.

A 16-year-old female with juvenile idiopathic arthritis presented with a one-month history of decreasing vision and increasing corneal edema in her left eye. Slit-lamp examination, keratometric measurements, and OCT evaluation led to a diagnosis of Terrien's marginal degeneration in both eyes along with a complete detachment of Descemet's membrane in the left eye and partial detachment in the right eye. She was treated with an intracameral injection of air and then topical betamethasone and chloramphenicol which lead to the resolution of symptoms.

Modified deep anterior lamellar keratoplasty for the treatment of advanced keratoconus with steep corneal curvature to help in eliminating the wrinkles in the Descemet's membrane.

Aims: To determine the clinical efficacy of modified deep anterior lamellar keratoplasty (DALK) for the treatment of advanced-stage keratoconus with steep curvature.

Materials And Methods: In this interventional, non-comparative case series, 30 patients with advanced stages of keratoconus and curvature of more than 60 D underwent a modified DALK procedure. In this technique, after big-bubble formation, posterior stromal lamella was cut and removed 5 mm centrally (baring Descemet's membrane completely) with posterior stromal layer remaining peripherally.

Anesthetic keratopathy presenting as bilateral Mooren-like ulcers.

This observational case report describes the development of bilateral Mooren-like ulcers in a patient with anesthetic keratopathy. A 42-year-old man with a recent history of minor eye trauma and pain self-treated with tetracaine eye drops presented with complaints of acutely worsening vision and severe pain bilaterally. His visual acuity at presentation was limited to hand motion.

Diplopia as the primary presentation of foodborne botulism.

Foodborne botulism is a serious condition caused by Clostridium botulinum neurotoxin. Clinically, botulism presents as bilateral cranial nerve neuropathy and descending paralysis. We report a unique presentation of botulism to remind clinicians of this potentially fatal condition.

Double anterior chamber in a patient with glaucoma and microspherophakia.

We report the case of a 16-year-old woman with microspherophakia and secondary open angle glaucoma. The patient presented with a membrane dividing the anterior chamber into two segments without edema or Descemet's membrane detachment. Slit lamp biomicroscopy, Pentacam, and specular microscopy images were obtained.

Corneal Crosslinking for Keratoconus in Iranian Patients: Outcomes at 1 year following treatment.

Aim And Design: A retrospective, nonrandomized, single-center clinical study was designed to evaluate the outcomes of corneal collagen crosslinking (CXL) for progressive keratoconus in Iranian patients 12 months after CXL.

Settings: This study was carried out at Navid Didegan Eye Center, a private clinic, Mashhad, Iran.

Materials And Methods: Ninety-two eyes of 53 subjects with progressive keratoconus were evaluated in this study.

Mechanical superficial keratectomy for corneal haze after photorefractive keratectomy with mitomycin C and extended wear contact lens.

Purpose: To evaluate the clinical results of a mechanical keratectomy with mitomycin C (MMC) and extended wear contact lens (EWCL) for the treatment of corneal haze after photorefractive keratectomy (PRK) of high myopia.

Setting: Eye Research Center, Khatam-al-Anbia Eye Hospital, Mashhad University of Medical Sciences, Iran.

Methods: : In a retrospective interventional case series, we enrolled 15 eyes of 9 patients who previously underwent PRK for high myopia and developed corneal haze and regression.

Preoperative subpterygeal injection vs intraoperative mitomycin C for pterygium removal: comparison of results and complications.

Purpose: To evaluate and compare the recurrence rates and complications between 2 therapeutic methods for primary pterygium: subconjunctival injection of mitomycin C (MMC) 1 month before bare scleral excision and conjunctival rotational flap with intraoperative MMC use.

Design: Prospective, interventional, randomized clinical trial.

Methods: setting: Institutional clinical trial in a tertiary, specialty eye hospital.
