Stop Your Search — Consolidate Sourcing to Protect Global Study Logistical Pipelines
Eliminating Multi-Vendor Logistical Friction
Coordinating purchases with multiple vendors introduces unnecessary complexity and fragmented logistics into your clinical trial planning—creating a tracking scenario that can quickly become unmanageable.
At Precision Vision, we make it standard practice to fulfill your entire optical equipment manifest through a centralized, certified channel. We streamline your procurement pipeline across a comprehensive diagnostic catalog: calibrated Illuminator Cabinets, classic ETDRS arrays, Contrast Sensitivity tests, computer-validated E-ETDRS suites, Grating Acuity kits, Reading Acuity cards, Low Vision parameters, and specialized Trial Lenses—customized precisely to your unique clinical endpoints.
Calibrated Optical Mediums: Trial Lenses & Filters
When reviewing trial optics, remember that lenses are not all created equal. Sub-standard refractive manufacturing compromises test repeatability across multi-center sites. Precision Vision acts as your single point of origin for certified refracting elements. We maintain extensive inventories of specialized lens parameters: Neutral Density Filters, Black Out Filters, Jackson Cross Cylinders, Full Diameter replacement lenses, complete Full Sets, and universal trial lens frames—guaranteeing premium optical clarity across every diagnostic variant.
Planning & Conducting a Successful Clinical Trial
Managing global studies means cross-referencing multiple countries, distinct trial sites, and overlapping protocol phases. Navigating equipment distribution, customs, international duties, and hardware recovery metrics is complex. A single supply chain failure or an uncalibrated hardware substitution can delay your timeline by weeks or months.
For more than 40 years, we have partnered directly with leading pharmaceutical companies and contract research organizations (CROs) to provide standardized vision testing solutions. From the initial cost quotation to final hardware recovery when fields close, we handle the entire process seamlessly — soup to nuts.
Over years of clinical coordination, our specialists have compiled best practices and operational parameters to help make your next investigational protocol efficient, compliant, and cost-effective.
Clinical Trial Supplies
When you partner with Precision Vision, Inc., your study receives hardware that is Clinically Proven and Universally Trusted, backed by our rigorous, Mission-Critical attention to detail. Browse our gold-standard inventories engineered explicitly for and by leading ophthalmic researchers.
Q: I see you have different variations of charts — Pelli-Robson Full Set (charts 1 & 2) versus individual 3 or individual 4, and ETDRS Charts with A, B, & C or Chart 1, 2, & 3. What are the differences between these product variations?
A: These variations represent precisely scrambled letter sequences. Quite simply, the optotypes are rearranged into alternative combinations from chart to chart. This variation is engineered to completely eliminate memorization bias during repeated patient testing across successive study visits. Every scrambled chart variant is manufactured to the identical colorimetric and dimensional standards, ensuring perfect data equivalence.
