Specialist Information
(1) Easy to fit and demonstrate
Ocutech offers diagnostic testing and demonstration systems of all of its low vision products. Ocutech offers complete prescribing guides, fitting charts, DVDs and videos, and convenient step-by-step ordering forms. Technical support is always available.
VES Bridge Mounting System
The innovative bridge and bracket mounting designs of many of Ocutech’s products allow its systems to be easily and conveniently demonstrated to patients during the evaluation visit. There is little prescribing risk as all critical telescope positioning can be readjusted at any time, even after dispensing. With Ocutech Low Vision Aids you can achieve a level of control never before available with a high quality low vision optical system. Even challenging eccentric viewing and nystagmus patients can be fit with ease. Call or email Ocutech for a complete professional catalog.
(2) Patient Referral System
Ocutech offers informational and instructional DVDs, patient information brochures and an active referral system for Ocutech prescribers. Ocutech also operates the Ocutech Ambassador Program which connects your prospective bioptic patients with experienced users for their.
(3) Ocutech VES Diagnosis Indications
Ocutech VES Telescope systems are indicated for all central vision, macular and retinal disorders where visual acuity is responsive to magnification. Individuals with vision as poor as 20/400 have benefited from VES devices.
Responsive visual diagnoses include macular degeneration, diabetic retinopathy, Stargardt's Disease, Hereditary macular degeneration, albinism, high myopia, nystagmus, coloboma, optic atrophy, macula holes, achromatopsia as well as many other vision disorders.
Ocutech VES Systems are appropriate for all bioptic telescope applications for far, intermediate and near distances, and for a full range of visual activities. The individual's specific visual needs, established in consultation with their low vision specialist, will determine which Ocutech device, if any, will be most appropriate to achieve their functional goals.
(4) How do I know if the patient is a promising candidate for a bioptic telescope?
Ocutech has developed a clinical prescribing protocol to help determine the prognosis for successful adaptation to bioptic telescopes. It addresses issues of acuity, contrast, ocular dominance, patient dexterity, patient goals and patient response.
(5) What power should be prescribed?
For general, non-demanding visual activities telescope power should be selected to provide at least 20/40 acuity through the device. For more demanding, higher resolution activities telescope power should be selected to provide at least 20/30 through the device.
(6) When to prescribe eyepiece corrections
All Ocutech VES bioptics provide internal Rx correction for a large range of spherical refractive errors (consult tech sheets for full ranges) and usually do not require additional eyepiece corrections. Cylinder corrections are not usually indicated when below 3 diopters. Auxiliary eyepiece corrections are not necessary if the patient can achieve their acuity goal through an equivalent testing telescopic device without such a correction.
(7) Which eye should the Ocutech VES be prescribed for?
It is desirable to prescribe for the dominant eye, so long as the acuity through the Ocutech VES is significantly better than the acuity of the non-dominant eye with the normal distance correction if any. If the non-dominant eye is the significantly better seeing eye, it is often necessary to at least partially occlude the dominant eye to aid sighting through the telescope.
(8) What should be considered in prescribing the carrier Rx?
We recommend prescribing the normal distance Rx in the carrier lenses including a bifocal if it is habitually used. We recommend conventional flat-top or round-segment bifocals rather than progressive lenses. If no distance Rx is normally worn, plano lenses should be ordered.
(9) How high should the bifocal segment be ordered.
We recommend at least 10mm between the bottom of the eyepiece and the top of the bifocal segment. Please see our frame catalog tech sheet that lists recommended maximum segment heights for all Ocutech frames.
(10) What can Ocutech VES - bioptics be used for?
Ocutech VES-Bioptics are appropriate for all bioptic telescope applications. These include television, travel, classroom, signs, faces, theater, sporting events, shopping, computer use, table top activities including games and card playing. bioptic telescopes can be used for driving where legal and with appropriate state licensure when required.
