Introduction to Intraocular Lenses (IOLs)
Intraocular lenses (IOLs) are implantable lenses used in eye surgery. These lenses replace the natural lens when it becomes cloudy, typically due to cataracts. As a result, they help restore vision and improve quality of life.
FDA Approval of the Aphtera® IC-8 Lens
In 2022, the FDA approved the Aphtera® IC-8 small aperture intraocular lens. Specifically, this lens uses the optical principle of the pinhole effect to improve the depth of focus, or range of vision. Therefore, it can help patients see more clearly at various distances.
The Principle Behind Pinhole Optics
The key idea behind pinhole optics is simple: the smaller the hole, the sharper the image. Consequently, a smaller hole allows fewer light rays to pass through. This, in turn, reduces blurring or distortion, leading to clearer vision.
Features of the IC-8 Intraocular Lens
The IC-8 intraocular lens is a hydrophobic acrylic posterior chamber IOL. It features a circular mask with a 1.36 mm central aperture. In addition, the pinhole mini-ring design in the center increases a patient’s range of vision. By doing so, it adjusts the focus of light rays entering the eye. Moreover, the IC-8 combines small-aperture optics with a monofocal IOL. Currently, its main application is presbyopia correction.
Benefits for Cataract Surgery Patients
Ultimately, we are excited to offer another tool to patients undergoing cataract surgery. This new option helps them achieve better vision quality and greater independence from glasses. In the long run, it can significantly improve their daily lives.
- Increase the depth of focus improving reading vision without glasses
- It’s indicated in patients with astigmatism and irregular corneas
- Depth of focus is increased, providing patients with good distance and near vision.
