Evaluation of Ocular Higher-Order Aberrations in First-Degree Relatives of Patients With Keratoconus.

Purpose: The aim of this study was to evaluate the corneal higher-order aberrations (HOAs) in first-degree relatives of patients with keratoconus (KCN) and compare with the normal population.

Methods: In this prospective comparative study, 210 eyes from 105 family members of 28 patients with KCN and 210 normal eyes of 105 controls were enrolled. In each eye, corneal topography, tomography, and aberrometry were performed and compared between the 2 groups.

Visual outcomes of photorefractive keratectomy in non-children with anisometropic amblyopia: One-year Follow-up Outcomes.

Objective: To evaluate the safety, efficiency, short term stability, and sensory results of photorefractive keratectomy (PRK) in anisometropic in non-compliant children with correction.

Methods: Twelve eyes of 12 children with an age range: 6-17 years and anisometropic amblyopia who underwent PRK under general anesthesia to correct the dioptric difference between the eyes were included in this study. A complete ophthalmic assessment including refractive status, uncorrected and corrected distance visual acuity (UDVA & CDVA), and binocular vision status using the Worth 4-dot test and stereopsis were performed before and 1, 3, 6, and 12 months after PRK.

The effect of eye dominancy on patients' cooperation and perceived pain during photorefractive keratectomy.

Purpose: To find a possible association between patients' cooperation, perceived pain, and ocular dominance in patients who undergo photorefractive keratectomy (PRK).

Methods: One hundred-one eligible candidates for PRK refractive surgery were recruited. Preoperative exams were performed for all patients, and the dominant eye was specified.

Stereoacuity after photorefractive keratectomy in myopia.

Purpose: Stereopsis, as a part of visual function, is the ability of differentiating between the two eyes' views (binocular disparity), due to the eyes' different positions. The aim of this study was to compare stereoscopic vision before and after photorefractive keratectomy (PRK) in myopia.

Methods: In a prospective interventional case series study clinical trial, forty-eight myopic individuals (age range: 18-34 years) who had undergone PRK surgery by a Bausch & Lomb Technolas 217z excimer laser were included.

A comparative study on visual and optical performance of Akreos AO and Kontur AB IOLs after phacoemulsification cataract surgery.

Purpose: Akreos AO and Kontur AB are two commonly used intraocular lenses (IOLs) in Iran. This study was designed to evaluate the visual performance of these lenses.

Methods: In a comparative interventional study, 35 patients (70 eyes) were recruited, and each IOL was implanted in one eye of the patients, randomly.

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.

Conjunctival necrosis and scleritis following subtenon triamcinolone acetonide injection.

The present study aims to report a case of conjunctival necrosis and scleritis due to a subtenon injection of triamcinolone acetonate. A 15-year-old boy received a subtenon injection of triamcinolone acetonate after a pars plana vitrectomy due to an intraocular foreign body. Seven days later, conjunctival necrosis and scleritis appeared at the site of injection.

Efficacy of extended-release oral diclofenac in postoperative pain management after photorefractive keratectomy.

Purpose: Inadequate pain control after photorefractive keratectomy (PRK) surgery can be a source of distress for patients and ophthalmologists. The purpose of this study was to evaluate the efficacy of extended-release diclofenac for the management of pain after PRK surgery.

Methods: In this prospective clinical trial study, patients in the case group were given extended-release diclofenac pre- and postoperatively, and patients in the control group were given acetaminophen and ibuprofen pre- and postoperatively.

Angle kappa changes after photorefractive keratectomy for myopia.

The goal of this study was to compare differences in the mean angle kappa and its intercepts before and after photorefractive keratectomy (PRK) for myopia. In a prospective controlled study, myopic patients were treated with aspheric wavefront-guided (personalized) PRK with a Bausch & Lomb Technolas 217z excimer laser. The manifest refraction, visual acuity, and angle kappa were evaluated preoperatively and at 1 and 6 months postoperatively.
