Effects of Lotrafilcon A and Senofilcon A Bandage Contact Lenses on Visual Outcome and Ocular Comfort After Photorefractive Keratectomy.

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.

The Reliability of YouTube as an Information Resource for Parents About Retinopathy of Prematurity.

Purpose: To investigate the quality and reliability of YouTube videos about retinopathy of prematurity (ROP) to direct parents of infants with the disease to access more accurate content.

Methods: The term "retinopathy of prematurity" has been searched on YouTube containing all of the videos between January 2 and February 2, 2024. The first 200 videos were evaluated by two ophthalmologists.

Comparison between wavefront-derived refraction and auto-refraction.

Background: This study aimed to compare objective refractive errors and keratometry measurements obtained using the Nidek OPD-Scan II aberrometer/topographer and Topcon KR 8900 autorefractokeratometer.

Methods: The right eye medical records of 176 patients aged 18-35 years who were admitted to our clinic as refractive surgery candidates were tested for refractive status and keratometry measurements with a Nidek OPD-Scan II aberrometer/topographer and a standard table-top autorefractokeratometer (Topcon KR 8900) before and after the induction of cycloplegia. Patients who had undergone any eye surgery and had hereditary, ectatic, or acquired corneal pathology were excluded.

Comparison of central corneal thickness measurements using three different imaging devices.

Purpose: The purpose of this study was to compare central corneal thickness (CCT) values and evaluate the agreement obtained with three different devices in healthy eyes.

Methods: A total of 120 eyes of 60 healthy individuals (36 men and 24 women) were enrolled in this retrospective study. CCT measurements were performed using an optical biometer (AL-Scan), spectral-domain optical coherence tomography (SD-OCT) (Topcon 3D) and ultrasonic pachymetry (UP) (Accupach VI), and the results were compared.

The Effect of Cycloplegia on the Biometer for Optical Low-coherence Reflectometry.

Purpose: The aim of this study was to compare the biometric measurements and different formulas for calculating intraocular lens (IOL) power by using the Lenstar LS900 biometer for optical low-coherence reflectometry before and after induction of cycloplegia in the adult population.

Materials And Methods: In this cross-sectional study, 168 eyes of 168 healthy volunteers aged 40 - 86 years (59.22 ± 11.
