Focusing of Light in the Eye01:16

Focusing of Light in the Eye

7.0K
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...

Angle Closure Glaucoma: Treatment

1.5K
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...

Open Angle Glaucoma: Treatment

1.1K
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...

Accessory Structures of the Eye

4.2K
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

1.6K
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...

Summary

Gas permeable scleral contact lenses (Rose K2 XL) significantly improve vision and patient satisfaction in individuals with irregular corneas who cannot tolerate traditional lenses. These scleral lenses offer a longer wearing time, enhancing visual function.

Area of Science:

  • Ophthalmology
  • Optometry
  • Biomedical Engineering

Background:

  • Irregular cornea conditions often lead to poor visual acuity.
  • Traditional gas permeable (GP) corneal contact lenses may not be tolerated by all patients.
  • Scleral contact lenses offer a potential alternative for visual rehabilitation.

Purpose of the Study:

  • To evaluate the effectiveness of Rose K2 XL GP scleral contact lenses in improving visual function.
  • To assess patient satisfaction with scleral lenses in cases of irregular corneas.
  • To compare scleral lens wear with previous GP corneal lens intolerance.

Main Methods:

  • A prospective study involving 15 patients with irregular corneas intolerant to GP corneal lenses.
  • Visual function was assessed using visual acuity and the visual function index (VF-14).
  • Measurements were taken before and after fitting with Rose K2 XL scleral lenses.

Main Results:

  • Significant improvement in visual acuity (0.06±0.07 logMAR) after fitting scleral lenses compared to baseline (0.31±0.18 logMAR).
  • Visual function index (VF-14) scores increased from 72.74±12.38 to 89.31±10.87, indicating enhanced patient satisfaction.
  • Patients reported comfortable wear of scleral lenses for an average of 9.33±2.99 hours per day.

Conclusions:

  • Rose K2 XL scleral contact lenses improve both visual acuity and patient-reported visual function in patients with irregular corneas.
  • Scleral lenses provide a viable and comfortable long-term wear option for patients intolerant to GP corneal lenses.
  • This study highlights the therapeutic potential of scleral lenses for managing complex corneal conditions.
