THE ROUTINE REMAINS

ASPIRA-aXA

PROVIDES THE SOLUTION

ASPIRA-aXA provides a custom solution for the most diverse needs. Possible applications range from standard cataract surgery to refractive surgery and combined interventions in retinal surgery.

FULFILLING PATIENT REQUIREMENTS

Advantages of an XL optic

LARGE PUPILS

With its XL optic the ASPIRA-aXA provides an ideal treatment option even under poor lighting conditions.

20% of cataract patients have a scotopic pupil diameter of ≥6 mm. In 10% of patients, even the mesopic pupil is ≥6 mm.

APPROX. 20 %
SCOTOPIC PUPIL DIAMETER ≥6 mm

APPROX. 10 %
MESOPIC PUPIL DIAMETER ≥6 mm

For an untroubled visual outcome

PREVENT PHOTIC PHENOMENA

  • Overlapping of the pupil with the IOL optic to prevent direct light passing the IOL and striking the retina directly, even with large pupil diameters
  • Incident light passes safely through the XL optic – including peripheral light incidence, which can be perceived as disturbing even with small pupils
  • Reduced interfering edge effects

ASPIRA-aXA

ELIMINATING DYSPHOTOPSIAS

The ASPIRA-aXA with its enlarged XL optic represents a promising approach to prevent negative dysphotopsia.

UP TO 20% – NEGATIVE DYSPHOTOPSIA
Almost 20% of patients notice negative dysphotopsia after implantation of a standard IOL

UP TO 3% – PERSISTENT
Nearly 3% of pseudophakic patients are severely impaired by negative dysphotopsia permanently

Negative Dysphotopsia

MULTIFACTORIAL ORIGIN

Negative dysphotopsia can occur after successful cataract sugery with IOL implantation. The reasons for development of negative dysphotopsia in pseudophakic eyes seem to be multifactorial. Discussed are among others:

  • Material properties

    e. g. a high refractive index of the IOL material

  • Lens design

    e. g. IOL edge design, optic-haptic transitions

  • Physiological factors

    e. g. pupil size or depth of the anterior chamber

A model

FOR THE DEVELOPMENT OF NEGATIVE DYSPHOTOPSIA

Numerous ray tracing analyses using standard IOLs show a non-illuminated region of the peripheral nasal retina. This “shadow” is caused by the reduced optic diameter and the central thickness of the artificial IOL compared to the natural lens.

Schematic drawing modified according to Holladay

2.5 mm pupil, 6.0 mm IOL

 

The retinal image is generated by light rays refracted by the IOL optic (areal A), as well as by light rays that hit the retinal periphery (area B) either directly or indirectly refracted by the IOL edge. The unilluminated gap between these two areas can lead to the perception of negative dysphotopsia.

ASPIRA-aXA

CLINICALLY CONVINCING

0% Negative dysphotopsia

  • All patients included in the study stated that they perceived no negative dysphotopsia after one year

100% Patient satisfaction

  • All patients were either very satisfied or satisfied according to a patient survey after treatment with ASPIRA-aXA

Outstanding visual results

  • Median corrected distant visual acuity was 1.2 (decimal); 96% of the patients achieved corrected visual acuity of 0.8 (decimal) or better after one year

Pseudophakic reliability

WHAT IS THE ADVANTAGE OF AN XL OPTIC?

RISK
Approx. 20% – diabetes mellitus type 2
Cases in the age group of the average cataract patient
Over 65% – develop diabetic retinopathy
In the group of diagnosed diabetics within 20 years

REASONS
For visual impairment, according to WHO, are mainly

  • diabetic retinopathy
  • myopia (with the risk of developing high myopia including resulting secondary diseases)

TENDENCY
increasing
  • Prevalence of diabetes mellitus is expected to increase by 50% by 2045
  • 10% of the world’s population is estimated to suffer from high myopia by 2050

    • PREVENTION
    An investment to the future
  • Screening and therapy reduce the risk of irreversible visual consequences
  • Timeliness and regularity are crucial

    • The panoramic IOL

    KEEPING TRANSPARENCY

    From a vitreoretinal point of view, both the surgeon and the postoperative doctor benefit from the extended fundus view. The assessment of the posterior segment of the eye and the implementation of therapeutic measures for peripheral retinal diseases can occur more conveniently.

    ASPIRA-aXA offers patients with an increased risk of ocular diseases an advantage for long-term, successful pseudophakic treatment.

    FOR AN EXCELLENT
    INTRAOPERATIVE VIEW

    • Opening of the anterior capsule membrane with a rhexis diameter of up to 6.5 mm
    • Allows an extended fundus view for the long-term monitoring of patients at risk

    FOR AN CONVENIENT
    POSTOPERATIVE FOLLOW-UP

    • Extended fundus view for convenient assessment of the tissue structures of the posterior segment of the eye
    • Facilitates therapeutic measures in the presence of peripheral retinal diseases

    Outstanding material meets best-in-class technology

    A MATERIAL TO WIN YOU OVER

    High transmission. High quality.

    • The ASPIRA-aXA achieves very high transmission levels
    • The high level of transmission attests excellent material quality, which is a crucial determinant of IOL image quality

    High Abbe number. High contrast sensitivity.*

    A high Abbe number, as a quality measure of the imaging properties of IOLs, is associated with

    • a reduction in chromatic aberrations in IOLs
    • higher image quality
