We report 2 cases in which an Artisan phakic intraocular lens (IOL) (Ophtec) was used to successfully treat high myopia after penetrating keratoplasty (PKP). The first case was a 43-year-old man who had a manifest refraction of -13.75 +3.00 x 50 with a best corrected visual acuity (BCVA) of 20/40(-2) after PKP in the left eye. Approximately 9 months after implantation of the Artisan IOL, the manifest refraction was -2.00 +2.50 x 60 with a BCVA of 20/30(+2). The second case was a 31-year-old man who had a manifest refraction of -10.75 +2.25 x 122 and a BCVA of 20/40 after corneal transplantation in the right eye. Ten months after implantation of the Artisan IOL, the manifest refraction was -2.75 +4.75 x 80 with a BCVA of 20/40. Endothelial cell density did not change significantly in either patient after surgery. The Artisan phakic IOL may provide an alternative method to correct high myopia after PKP.

Background: Refractive errors are common visual comorbidities among the elderly. Cognitive dysfunction also occurs in this population. A study by Ong et al (2013) demonstrated an association of refractive errors with poor cognitive performance.

Anorexia nervosa (AN) is a psychiatric eating disorder characterized by body mass index (BMI) ≤ 18.5, fear of gaining weight, and a distorted perception of body weight. With increasing rates of myopia, there is a population of patients who concurrently develop AN and may seek corneal refractive surgery.

Background: acquired exotropia mostly manifests as an intermittent form, and very few cases show constant exotrpia. However, the differences in the clinical features of the constant and intermittent exotropia patients has not been clear yet.
Methods: We retrospectively evaluated 6159 patients with exotropia from 2012 to 2022 in Farabi Eye Hospital, Tehran, Iran.

Terahertz waves are nondestructive and non-ionizing to synthetic and natural materials, including polymeric and biological materials. As a result, terahertz-based spectroscopy has emerged as a suitable technique to uncover fundamental molecular mechanisms and material properties in this electromagnetic spectrum regime. In terahertz time-domain spectroscopy (THz-TDS), the material's optical properties are resolved using the raw time-domain signals collected from the sample and air reference data depending on accurate prior knowledge of the sample geometry.
