Summary
New dual-focus (DF) contact lenses for myopia control show visual performance comparable to multifocal (MF) lenses. While effective, some visual compromises like reduced quality and ghosting may occur under certain lighting conditions.
Area of Science:
- Ophthalmology
- Optometry
- Vision Science
Background:
- Multizone/dual-focus (DF) soft contact lenses are emerging as a potential intervention for controlling myopia progression.
- A new DF soft contact lens (MiSight, CooperVision) is now commercially available, necessitating an evaluation of its visual performance.
Purpose of the Study:
- To assess the visual acceptability and performance of a new dual-focus (DF) soft contact lens designed for myopia control.
- To compare the visual outcomes of the DF lens against a standard multifocal (MF) contact lens and best-spectacle correction (BC).
Main Methods:
- A double-masked, randomized, crossover trial involving 24 young adults (18-25 years) was conducted.
- Participants wore DF and MF soft contact lenses, with visual performance assessed under high-illumination-high-contrast (HIHC) and low-illumination-low-contrast (LILC) conditions at various distances.
- Patient-reported outcomes and objective visual acuity measures were collected after one week of daily wear.
Main Results:
- No significant differences in distance visual acuity were found between the DF lens, MF lens, and best-spectacle correction (BC) under HIHC conditions.
- Under LILC conditions, both DF and MF lenses showed significant differences in visual acuity compared to BC at distance and intermediate viewing distances.
- While visual quality and ghosting ratings were lower for both DF and MF lenses compared to habitual correction, no significant difference was observed between the DF and MF lenses themselves.
Conclusions:
- The new DF contact lens offers good visual acuity, comparable to standard MF lens correction, for myopia control.
- Users may experience some reduction in visual performance, including decreased visual quality and increased ghosting, particularly under low-illumination conditions, which is characteristic of multifocal contact lens designs.

01:16Focusing of Light in the Eye
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
01:27Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
01:22Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
01:23Ophthalmic Drug Delivery Systems
Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...
