Focusing of Light in the Eye01:16

Focusing 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...
Photoreceptors and Visual Pathways01:22

Photoreceptors 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...
Accessory Structures of the Eye01:17

Accessory Structures of the Eye

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
Glaucoma: Overview01:25

Glaucoma: 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...
Open Angle Glaucoma: Treatment01:27

Open 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.
Drugs such as carbonic anhydrase inhibitors, α2- and...
Microbiome of the Eye01:22

Microbiome of the Eye

The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...

Summary

12.2% of soft contact lens wearers report sensitive eyes (SEs). Refitting with senofilcon A silicone hydrogel lenses significantly reduced SE symptoms like dryness and irritation, offering relief for sensitive eyes.

Area of Science:

  • Ophthalmology
  • Optometry
  • Biomedical Engineering

Background:

  • Sensitive eyes (SEs) are a common complaint among soft contact lens (CL) wearers.
  • Understanding the characteristics of SE patients is crucial for improving CL comfort and compliance.

Purpose of the Study:

  • To determine the prevalence of self-reported sensitive eyes (SEs) in soft contact lens wearers.
  • To evaluate the clinical features of patients experiencing SEs.
  • To assess the efficacy of refitting with senofilcon A silicone hydrogel lenses for SE management.

Main Methods:

  • A self-assessment survey identified 2154 soft contact lens wearers as either SE or non-SE patients.
  • Demographic, biometric, wearing time, and symptom data were compared between groups.
  • Sixty-three SE patients were randomized to wear senofilcon A (senA) lenses, while 65 wore non-senA lenses.
  • Lens performance was evaluated after 2 weeks by comparing senA lenses against habitual and non-senA lenses.

Main Results:

  • 12.2% of soft contact lens wearers reported SEs with their habitual lenses.
  • SE patients exhibited higher rates of dryness, irritation, redness, and stinging compared to non-SE patients.
  • Refitting with senofilcon A lenses significantly improved reported dryness, irritation, redness, and stinging compared to habitual and non-senA lenses.

Conclusions:

  • A significant portion of soft contact lens wearers experience sensitive eyes, primarily characterized by subjective symptoms.
  • Senofilcon A silicone hydrogel lenses demonstrate a notable capacity to alleviate symptoms associated with sensitive eyes.
  • These findings suggest that specific lens materials, like senofilcon A, can effectively manage sensitive eyes in contact lens wearers.
