Corneal Refractive Surgery Considerations in Patients with Anorexia Nervosa.

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.

Combination Low-Dose Pilocarpine/Diclofenac Sodium and Pilocarpine Alone for Presbyopia: Results of a Randomized Phase 2b Clinical Trial.

Purpose: To evaluate the efficacy of 0.2% and 0.4% pilocarpine HCl (CSF-1) for the treatment of presbyopia and to determine the contributions of pilocarpine HCl and diclofenac sodium on the efficacy of fixed-dose combination (FDC) formulations.

Assessing the Role of Artificial Intelligence in the Creation of Patient Educational Videos for Corneal Refractive Surgery.

Purpose: We aim to assess the ability of artificial intelligence (AI) to generate patient educational videos for various corneal refractive surgeries.

Methods: Three AI text-to-video platforms (InVideo (San Francisco, CA), ClipTalk (San Francisco, CA), and EasyVid (Los Angeles, CA)) were used to create patient educational videos for laser-assisted in situ keratomileusis (LASIK), photorefractive keratectomy (PRK), and small incision lenticule extraction (SMILE), respectively. Videos for LASIK and PRK from the American Academy of Ophthalmology (AAO) and a SMILE video from Zeiss served as controls for each surgery.

Corneal Refractive Surgery Considerations in Patients With History of Orthokeratology.

Objective: To review the current literature describing corneal changes observed with orthokeratology (ortho-k) use and to formulate preliminary recommendations for these patients seeking corneal refractive surgery.

Methods: The literature search was conducted through the PubMed, Scopus, and Ovid databases through June 4, 2024, for articles regarding corneal physiological, tomographic, and biomechanical changes secondary to ortho-k use.

Results: Forty-one articles were found describing several changes associated with ortho-k use, including higher corneal staining, central corneal epithelial thinning and midperipheral thickening, increased higher-order aberrations, decreased contrast sensitivity, reduced corneal hysteresis and corneal resistance factor, and alterations in the tear proteome.

Assessing Changes in Corneal Densitometry in Patients After Small Incision Lenticule Extraction (SMILE).

Purpose: The aim is to assess for any lasting changes in corneal densitometry (CD) in patients who underwent small incision lenticule extraction (SMILE) and developed early transient postoperative corneal haze.

Methods: This retrospective chart review analyzed 98 eyes from 49 patients who underwent SMILE at the Hoopes Vision Clinic and had one-year postoperative Pentacam CD (Oculus Optikgeräte GmbH, Wetzlar, Germany). These were compared to 78 eyes from 42 unoperated myopic control patients with documented CD measurements.
