Ophthalmic prism bar set, horizontal and vertical loose prism bars for measuring strabismus, phorias, vergence facility, and fusional reserves. Horizontal bar covers 1-40 prism diopters (1/2/4/6/8/10/12/14/16/18/20/25/30/35/40Δ) for esotropia and exotropia measurement. Vertical bar covers 1-25 prism diopters (1/2/3/4/5/6/8/10/12/14/16/18/20/25Δ) for hypertropia and vertical phorias. Comes in protective case. Essential equipment for pediatric ophthalmology, orthoptics, adult strabismus, and vergence dysfunction workup.

Clinical Applications
- Strabismus measurement (prism and alternate cover test): quantifying esotropia, exotropia, hypertropia in prism diopters
- Fusional reserve testing: measuring positive and negative fusional convergence
- Phoria measurement: heterophorias (latent misalignment) via cover test
- Vergence facility testing: dynamic accommodation-vergence workup
- Pediatric ophthalmology workup: infantile esotropia, accommodative esotropia
- Post-strabismus surgery evaluation: residual deviation quantification
- Orthoptics and vision therapy: baseline and progress measurement
- Diplopia workup: measuring binocular vision defects
- Nystagmus and oscillopsia evaluation
- Pre-op strabismus planning: Krimsky method, prism and cover test

FAQ
How does this compare to Berens or Katena prism bars?
Feature parity on prism diopter values, optical glass grade and case. Berens, Katena have slightly higher polish and tighter tolerance on prism angle QC. Price differential: $300 vs $650-$1,200 for Berens / Katena. For most clinical strabismus measurement, this SciMed set delivers full clinical utility at 30-45% of premium OEM pricing.
Why loose prism bars vs individual loose prisms?
Prism bars keep all diopter values organized in a single handheld device, faster clinical workflow than searching through a case of individual loose prisms. For fine measurement in between bar values (e.g. 17Δ), use bar and loose prism combined.
What's the difference between horizontal and vertical bars?
Prism base direction is what's measured. Horizontal bar (base-out or base-in) measures horizontal deviations, eso/exo. Vertical bar (base-up or base-down) measures vertical deviations, hyper/hypotropia. Both needed for complete strabismus workup.
