How can I learn strabismus?

Strabismus Simulator

1. Cover-uncover test. See which eye is dominant, and if the deviation is manifest/tropic.
2. Alternate cover test. See the entire potential deviation: tropia and phoria.
3. Alternate cover test with prism. Measure the entire potential deviation: tropia and phoria.
4. Simultaneous prism cover test.

What does a refraction test do?

A refraction test is usually given as part of a routine eye examination. It may also be called a vision test. This test tells your eye doctor exactly what prescription you need in your glasses or contact lenses. A refractive error means that the light is not bending properly when it passes through the lens of your eye.

How does virtual refractor work with virtual patients?

TRY NOW Virtual Refractor simulates a distance and near subjective optometric refraction, using a refractor head on virtual patients. There are numerous patients, prescriptions and profiles, and the patients respond to test questions and charts based on user input.

What’s the best way to learn to refract?

Like many procedures, refraction is difficult skill to learn by reading or watching videos. While nothing beats working on a real refracting instrument, a virtual refractor is the next best thing. Practice on an unlimited number of virtual patients. What’s so great about a virtual patient?

What is the difference between subjective and manifest refraction?

Subjective (manifest, dry): Using a refractor (also known as a phoroptor) to allow a patient to provide their subjective response about their prescription. Cycloplegic (wet): A refraction after a patient has had cycloplegic drops to paralyze their accommodation. For this tutorial, we will cover manifest refraction.
