Pinhole occluder
The occluder is a simple way to focus light, as in a pinhole camera, temporarily removing the effects of refractive errors such as myopia. The pinhole occluder can also be used in testing visual acuity in mydriatic patients.

Diopter sight
The typical occluder used in target shooting diopters is a disc of about in diameter with a small hole in the middle. The non-aiming eye can be blocked from seeing distractions by mounting a semi-transparent occluder to the diopter.

First Experience With Amulet in the United States
4 days agoA total of 5,499 patients underwent attempted Amulet occluder implantation. Implant success was 95.8%, and complete closure was 97.2% post-LAAO and 87.1% at 45 days. A safety composite endpoint event occurred in 0.76% of patients. Any major adverse event occurred in 2.9% and 5.7% of patients in-hospital and through 45 days, respectively, driven ...

Kurt Amplatz
He is best known for the invention of the Amplatzer Septal Occluder as well as the Amplatzer Cribriform Occluder, which is used for closing atrial septal With his son, Curtis, he developed the Amplatzer Occluder, which introduced a mesh via a catheter that could close holes in the heart.

Aragoscope
Concept
The light diffracted around the edge of a perfectly circular occluder interferes constructively at the central axis, and the resolution at that point would be equal to the resolution of conventional lens with the same size of the occluder.

Subjective refraction
An occluder is placed over the eye that is not being tested (e.g.: over the left eye, to test the right eye's vision). A pinhole occluder is then placed before the patient's eye, and their vision is then tested again (each eye separately) to determine if the patient's poor

Ophthalmic trial frame
Uses
To measure a patient's refractive error, squint and presbyopia, it is used to hold lenses, prism or other tools like pinhole occluder. Parts
An ideal trial frame have minimum 3 cells, one each for holding spherical lens, cylindrical lens and other tools like occluder or pinhole.
