Affluence and Contact Lens Prescribing
Objectives: To assess the impact of national affluence on the extent of prescribing of various types of soft contact lenses. Methods: Using information derived from a large bank of contact lens prescribing data, the relationship between the percentage prescribing of daily disposable, toric, silicone hydrogel, and multifocal contact lenses versus the gross domestic product at purchasing parity per capita (GDP [PPP]) was determined for all countries in which contact lens prescribers returned survey forms relating to greater than 100 contact lens fits between 2017 and 2021, inclusive. Results: Data from 39 c...

Small Incision Lenticule Extraction in Myopic Eyes With Corectopia After Intraocular Lens Implantation
We present a case of ametropia corrected by small incision lenticule extraction (SMILE) in a corectopia eye after cataract surgery. The patient's optical zone, nomogram, and centration were carefully considered. The intended corrections were −6.60 − 1.25 × 175 OD and −6.85 − 0.50 × 10 OS. M-sized and S-sized cones were recorded in the right and left eye, respectively. The diameter of the right eye optical zone was 7.00 mm, whereas that of the left eye was 6.50 mm. The corneal vertex was determined using the film mark method as the scanning center. Three months after surgery, the uncorrected distance visual acuiti...

A New Contact Lens Sensor System for Continuous Intraocular Pressure Monitoring: Evaluation of Safety and Tolerability
Purpose: To assess the safety and tolerability of a new contact lens sensor (CLS) system for continuous 3- and 24-hr intraocular pressure (IOP) monitoring in human eyes. Methods: Twenty-five subjects were recruited for 3-hr IOP measurement by CLS. Corneal fluorescein staining (CFS) scores were evaluated before and after measurement. Then, 30 participants (10 normal subjects and 20 glaucoma patients) were recruited for 24-hr IOP monitoring. Ocular surface disease index (OSDI) was assessed before and one day after measurement. Contact lens dry eye questionnaire-8 was assessed immediately after measurement. Visual ...

A Comparative Study of Two Extended Depth of Focus Intraocular Lenses
Conclusion: There was no significant difference between the two groups regarding uncorrected/corrected distance VA, UIVA, UNVA (40 cm), RE, optical quality parameters, and patient-reported quality of vision questionnaire results. The Symfony group demonstrated a significantly superior UNVA (33 cm) and a smoother defocus curve with a broad landing zone. (Source: Eye and Contact Lens: Science and Clinical Practice)

Effect of Intense Pulsed Light Therapy in Dry Eye Disease Caused by Meibomian Gland Dysfunction: A Systematic Review and Meta-Analysis
Conclusion: We identified that the application of IPL alone or IPL combined with MGX elicited superior clinical effect for improving the eye function and symptoms in the treatment of MGD-related dry eye disease, which is considered available for wide clinical application.

Determining the Best Management Strategy for Preventing Short-Term Effects of Digital Display Use on Dry Eyes
Objectives: To assess and compare the effectiveness of four main management strategies for preventing short-term effects of digital display use on dry eye signs and symptoms. Methods: The ocular surface, tear film, and visual fatigue of 47 healthy individuals were assessed before and after reading on a laptop computer for 20 min under five different experimental conditions: control, instillation of artificial tears, taking a brief break, using a blue light screen filter, and blink control. Measurements included the Ocular Surface Disease Index (OSDI) Questionnaire, 5-item Dry Eye Questionnaire (DEQ-5), tear meni...

Dry Eye–Related Risk Factors for Digital Eye Strain
Objectives: To evaluate dry eye–related lifestyle and demographic factors associated with digital eye strain (DES). Methods: An anonymous online survey was conducted in 851 university students. Participants were classified into DES (computer vision syndrome questionnaire [CVS-Q]≥6) or non-DES (CVS-Q (Source: Eye and Contact Lens: Science and Clinical Practice)

A Review of Pathologic Myopia
Abstract: Pathologic myopia is a leading cause of vision loss worldwide and is most prevalent in developed nations in East and Southeast Asia. Although the pathophysiologic mechanisms behind pathologic myopia have yet to be elucidated, the process is thought to stem from excessive axial elongation of the globe and subsequent degeneration of vital structures within the posterior segment. The array of complications that arise from this condition can lead to significant visual impairment. The purpose of this article is to review the classification, pathophysiology, complications, and management of pathologic myopia. (Sour...

Efficacy of the Image-Guided Alignment System for a Four-Haptic Hydrophobic Monofocal Toric Intraocular Lens
This study included 49 eyes of 44 patients (women: 68%; mean age: 67.2±7.0 [range: 47–82] years). Twenty-nine eyes of 26 patients were treated with toric IOL implantation using the image-guided system and 20 eyes of 18 patients were treated using the manual-marking method. No statistical differences were observed regarding the baseline characteristics of the two groups. Three months after the surgery, the misalignment of the toric IOL was significantly lower in the image-guided group (2.18°±0.65°, range: 1.26°–3.95°) than in the manual; marking group (4.72°±0.74°, range: 3.44°–6.21°; P (Source: Eye and Con...

Comparison of Ocular Biometric Parameters Between Hispanic and Non-Hispanic Ethnicities in White Adults Undergoing Cataract Surgery
Conclusions: Anterior chamber depth is significantly shorter in Hispanic patients compared with non-Hispanic patients. Such ethnic difference should be considered when performing cataract and corneal surgeries because this ethnic difference may be associated with a higher risk of corneal endothelial injury.

Evaluation of Ocular Surface Characteristics in Dry Eye Disease With and Without Soft Contact Lens Wear: A Comparative Study
Conclusions: Patients with DED with CLW showed greater epithelial damage, elevated inflammatory cytokines and neuromediators in tears, and higher corneal dendritic cell density than patients with DED without CLW. The immune and nervous systems may be involved in contact lens–related DED. (Source: Eye and Contact Lens: Science and Clinical Practice)
