Prescriber FAQs

What makes Ocutech bioptics so special?

Easy to fit and demonstrate

The innovative mounting design of Ocutech’s products allow its systems to be easily and conveniently demonstrated 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 telescope system. Even challenging eccentric viewing and nystagmus patients can be fit with ease.

Ocutech offers complete prescribing guides, fitting charts, online videos, and convenient step-by-step ordering forms. Diagnostic testing and demonstration systems are available for all of Ocutech’s low vision products. Technical support is always available. Contact Ocutech for complete professional information.

Which patients should I consider for bioptic telescopes?

Ocutech bioptic telescope systems are indicated for individuals with reduced central vision where visual acuity is responsive to magnification. Individuals with vision of 20/300 and better have benefited from Ocutech devices.

Diagnoses responsive to telescopic low vision aids include macular degeneration, diabetic retinopathy, Stargardt’s Disease, Hereditary macular degeneration, albinism, high myopia, nystagmus, coloboma, optic atrophy, macula holes, achromatopsia, rod/cone dystrophies, as well as many other vision disorders.

How do I know if my patient is a promising candidate for an Ocutech telescope system?
Ocutech has developed a clinical prescribing worksheet and accompanying Webinar to help you determine your patient’s prognosis and appropriate prescription for low vision telescopes.
When should I prescribe eyepiece corrections?

All Ocutech VES bioptics provide internal Rx correction for a large range of spherical refractive errors (consult Product Comparison Chart for full ranges) and usually do not require additional eyepiece corrections.

For VES systems eyepiece corrections should be considered for spherical refractive errors beyond +/-10D or 3D cylinder.

SightScope Systems do not requires eyepiece corrections as the telescopes are positioned in front of the carrier lenses.

Visit the Product Directory for specific prescribing options and recommendations for each product.

Which eye should the Ocutech telescope be prescribed for?

It is preferable to prescribe to the dominant eye (even if it is the poorer seeing eye) so long as you can achieve the acuity goal you seek through the telescope. If the non-dominant eye is the significantly better seeing eye, it may be necessary to at least partially occlude the dominant eye to aid sighting through the telescope.

What prescription should be ordered in the carrier lenses?
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 or trifocals. If no distance Rx is normally worn, plano lenses should be ordered.
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 the recommended maximum segment heights for all Ocutech frames.
