Purpose: To evaluate the visual, motor, and sensory outcomes of photorefractive keratectomy (PRK) in the treatment of purely refractive accommodative esotropia in young adult patients.
Setting: Policlinico Umberto I, Department of Ophthalmology, Rome, Italy.
Methods: This prospective study comprised patients with hyperopia and purely accommodative hyperopic esotropia. A complete ophthalmologic examination was performed preoperatively and 1, 3, and 12 months postoperatively. The examination included uncorrected (UDVA) and corrected (CDVA) distance visual acuities and orthoptic and sensory tests. All patients also had keratometry, pachymetry, and corneal topography assessment before and after treatment. Treatment was performed using a Technolas 217 excimer laser.
Results: Thirty eyes of 15 patients (mean age 30.8 years) were treated. Preoperatively, the CDVA was 20/30 or better in all eyes and the mean cycloplegic spherical equivalent (SE) was +3.50 diopters (D). One year postoperatively, the UDVA was 20/30 or better in all eyes and the mean SE was -0.01 D. The mean esotropic deviation for distance vision without correction preoperatively was 8.7 prism diopters. At 1 year of follow-up, 12 patients achieved orthophoria and 3 patients had a reduction in the angle of deviation. There were no intraoperative or postoperative complications. Stereopsis was unaffected by treatment in all patients.
Conclusions: Photorefractive keratectomy was effective in the treatment of purely accommodative esotropia in young adult patients at a follow-up of 1 year. There were no cases of visual acuity loss or complications from the laser treatment.

Objectives: To compare the efficacy of two different silicone hydrogel bandage contact lenses (BCLs) in terms of visual rehabilitation and ocular discomfort following photorefractive keratectomy (PRK).
Materials And Methods: This prospective study included 60 eyes of 30 patients who underwent bilateral PRK surgery to correct myopia and/or astigmatism refractive errors. Following surgery, lotrafilcon A BCLs were applied to the right eye and senofilcon A BCLs were applied to the left eye.

Purpose: To compare the refractive prediction accuracy of the Optiwave Refractive Analysis (ORA) SYSTEM with the Barrett True-K (BTK) formula in calculating intraocular lens (IOL) power in eyes that underwent cataract surgery after previous myopic photorefractive keratectomy (PRK) or laser-assisted in situ keratomileusis (LASIK).
Methods: This retrospective study evaluated patients aged ≥22 years with prior myopic PRK or LASIK who underwent unilateral or bilateral cataract removal and monofocal IOL implantation using the ORA SYSTEM at 177 sites in the United States. Two datasets were analyzed: All Eyes (ie, all eligible eyes) and First Surgery Eyes (ie, each patient's first implanted eye).

A 23-year-old woman was referred for low visual acuity in the left eye after a corneal ulcer associated with contact lens use 2 years previously. The patient had a history of contact lens use, reported use of antibiotic eye drops with improvement of infection, and subsequent scarring. There were no comorbidities.

Article Synopsis
- - Corneal haze results from abnormal healing processes following injuries or surgeries, causing vision impairment due to eye opacity and irregularities, often linked to myofibroblast formation triggered by inflammation.
- - Major causes of corneal haze include surgical procedures like PRK and LASIK, as well as non-surgical factors such as trauma and infections, with research focusing on the TGFβ pathway and inflammation management methods.
- - Losartan, usually used for treating high blood pressure, shows promise in ophthalmology for reducing corneal fibrosis after various injuries and surgeries, leading to this review of its effectiveness and potential future applications in treating corneal haze.
Purpose: To compare clinical outcomes of transepithelial photorefractive keratectomy (t-PRK) and conventional epithelium-off PRK (PRK) in patients with high compound myopic astigmatism.
Methods: Sixty eyes of 30 myopic individuals with at least -2.50 diopters (D) of spherical equivalent and 3.
