Posterior Segment Visualization in Eyes With Small-Aperture Intraocular Lens
Journal of Refractive Surgery (Thorofare, N.J. : 1995)
|August 9, 2019
Summary
Small-aperture intraocular lenses (IOLs) allow for effective posterior segment visualization. Standard diagnostic imaging and intraoperative views remain uncompromised in patients with these advanced IOLs.
Area of Science:
- Ophthalmology
- Optics
- Medical Imaging
Background:
- Small-aperture intraocular lenses (IOLs) offer a novel approach to vision correction.
- Evaluating the impact of new IOL technologies on diagnostic capabilities is crucial.
Purpose of the Study:
- To assess the quality of posterior segment visualization in eyes with small-aperture IOLs.
- To determine if small-aperture IOLs impede standard ophthalmic diagnostic procedures.
Main Methods:
- Prospective comparative case series of 15 patients with unilateral small-aperture IOL implantation.
- Bilateral posterior segment investigations: fundus photography, threshold perimetry, optical coherence tomography (OCT).
- Intraoperative visualization during pars plana vitrectomy was subjectively evaluated.
Main Results:
- Successful image capture with all diagnostic tools in all 15 patients.
- No discernible difference in image quality between small-aperture IOL eyes and control eyes.
- Small-aperture IOLs did not obstruct intraoperative views for retinal surgeons.
Conclusions:
- Standard posterior segment investigations are safe and effective with small-aperture IOLs.
- Non-mydriatic fundus photography, OCT, and automated perimetry yield comparable image quality.
- Small-aperture IOLs do not compromise diagnostic imaging or surgical visualization.

01:14Cranial Bones: Superior and Posterior View
4.9K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:20Muscles of the Eye
4.0K
The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and...

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...

01:16Focusing of Light in the Eye
5.5K
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...

Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...
