Clinical overview
Product overview
The OpticsMED 20 D / 90 D Aspherical Retina lens is the indirect-fundoscopy lens that pairs with a slit lamp for examination of the optic disc, macula and posterior pole. The 90 D is the workhorse choice for slit-lamp biomicroscopy (wider field, lower magnification); the 20 D is the partner for indirect ophthalmoscopy in the same clinic. The aspheric surface eliminates the off-axis aberration that older spherical fundus lenses introduce at the disc margin.
Key features
- Aspherical front surface — clean image to the disc margin
- 20 D variant for indirect ophthalmoscopy (wider field, head-mounted scope)
- 90 D variant for slit-lamp biomicroscopy (precision posterior-pole exam)
- Anti-reflective coating reduces stray-light artefact
- Compatible with any condensing slit lamp design
Specifications
| Variants | 20 D, 90 D |

Built for
Ophthalmology clinics that run dilated fundus exams as part of glaucoma, diabetic-retinopathy or age-related macular degeneration workups. The 90 D is the slit-lamp pairing; the 20 D fits clinicians who also use a head-mounted indirect ophthalmoscope during dilated screening.

90D Aspherical Retina Lens for Slit Lamp Fundus Examination — Wide-Field Posterior Segment Viewing
The 90D is an aspherical retina lens used with a slit lamp for indirect fundus examination of the posterior segment. It is a standard wide-field option for routine retinal evaluation in optometry and ophthalmology practice. The aspherical design is intended to provide clear viewing of the optic nerve, macula, and peripheral retina during slit-lamp biomicroscopy. It is supplied as an individual lens for clinicians who already use a compatible slit lamp setup.
78D Aspherical Retina lens for Slit-Lamp Fundus Examination
78 D aspherical retina lens — the higher-magnification slit-lamp fundus lens for detailed macular and optic-disc examination during dilated workup.
SW-800 Handheld Auto Refractometer for Pediatric & Bedside Refraction — Portable Objective Measurement
The SW-800 is a handheld auto refractometer designed for objective refraction in settings where a benchtop autorefractor is impractical. Portability supports pediatric clinics, mobile vision programs, school screening, and bedside refraction for non-cooperative or wheelchair-bound patients. The instrument captures objective sphere, cylinder, and axis to provide a starting point for the subjective refraction. Suited to optometrists, ophthalmologists, and outreach programs needing a transportable refraction tool.
468-4310 Retinoscope & Ophthalmoscope Premium Inspection / Measurement Set — Fiber Optic LED with USB Rechargeable Handle
The 468-4310 is the premium tier of the 468 inspection / measurement set range, combining an ophthalmoscope and streak retinoscope with a fiber-optic illuminator and an upgraded LED platform. It runs on a USB-rechargeable handle and is supplied in a fitted zipper case. The fiber-optic illumination is intended for clinicians who want a higher-output light path than the standard tier for fundus and retinoscopy work. It is suited for optometry and ophthalmology practices that need a more robust inspection / measurement kit for daily clinical use.
468-4300 Retinoscope & Ophthalmoscope Inspection / Measurement Set for Optometry — LED with USB Rechargeable Handle
The 468-4300 is a combined ophthalmoscope and streak retinoscope inspection / measurement set built around an LED illumination platform and a USB-rechargeable handle. It is supplied in a fitted zipper case for clinic or home-visit use, ready for routine fundus examination and retinoscopy refraction. The rechargeable handle removes the need for disposable batteries and keeps the instrument set ready between cases. It is intended for use by optometrists and ophthalmologists in primary eye-care practice.
FA-6100BK Auto Refractometer/Keratometer for Optometry Practice — Combined Refraction & Corneal Curvature Measurement
The FA-6100BK is the combined auto refractometer/keratometer variant in the FA-6100 family, adding corneal curvature measurement on top of objective refraction in a single workflow. Performing refraction and keratometry on one device cuts patient handling time and helps streamline pre-test for contact-lens fitting and routine eye exams. The desktop format suits optometry practices and eye clinics looking for one consolidated pre-test station. A practical step up from the refraction-only FA-6100B for offices that also need K-values.
LP-23H Loose Prism with Handle for Binocular Vision Testing — Acrylic Lumpish Prism in Aluminium Case
The LP-23H is a loose prism with handle, built from acrylic in a lumpish prism form and supplied in an aluminium carry case. Loose prisms with handles are used by optometrists and orthoptists to introduce known prism powers in front of the eye when assessing fusion, phorias and tropias. The handled format makes the prism easy to position quickly during cover-uncover and prism-cover testing. A standard binocular-vision tool for optometry practices, orthoptic clinics and vision-therapy rooms.
