    PRESBYOND Laser Blended Vision

    A clear choice for presbyopic patients

    PRESBYOND® Laser Blended Vision from ZEISS is an advanced method for treating patients with age-related loss of accommodation, also known as presbyopia. It offers the opportunity to achieve freedom from glasses by combining the simplicity and accuracy of corneal refractive surgery with the benefits of increased depth of field in retaining visual quality. As a surgical solution based on the naturally occurring spherical aberrations of the eye, PRESBYOND Laser Blended Vision extends the scope of customized ablation beyond the limits of conventional monovision laser methods in several ways.

    Whether for its customized treatment profiles, its visual acuity at all distances, its indications range or its immediate impact, PRESBYOND Laser Blended Vision is a clear treatment choice for the fast growing demographic of presbyopic patients.

    PRESBYOND Laser Blended Vision

    Next level vision correction beyond conventional monovision

    Although similar to conventional monovision laser treatments in terms of the workflow, PRESBYOND® Laser Blended Vision takes customized vision correction a step beyond, particularly with respect to the outcomes.

    PRESBYOND Laser Blended Vision

    A new, physiologically optimized laser treatment method for presbyopic patients, PRESBYOND Laser Blended Vision represents the next stage in eye care excellence. Similar to conventional monovision, the dominant eye is corrected for distance vision to almost plano, whereas the non-dominant eye is corrected to be slightly myopic for near vision to -1.5 D. This micro-monovision strategy is further enhanced by a decisive difference: an increase in the depth of field of each eye using a wavefront-optimized ablation profile to create a continuous refractive power gradient for the whole optical zone of the cornea. PRESBYOND Laser Blended Vision is an absolutely individualized treatment plan based on preoperative spherical aberrations and the functional age of the eye. As a result, a customized fusion of the two images for near and distance vision is created for each patient – the so-called "Blend Zone".

    The unique Blend Zone
    Essentially, the Blend Zone makes it easier for the brain to merge the images of both eyes, thereby achieving true binocular vision. This is a significant advantage over conventional monovision. In addition to excellent near and far vision, PRESBYOND Laser Blended Vision patients also experience very good visual acuity and contrast sensitivity in the intermediate range. They adapt faster and most are delighted about not having to wear glasses anymore.

    Not surprisingly, PRESBYOND Laser Blended Vision is tolerated by a high number of patients – up to 97 %.1

    Conventional monovision

    With conventional monovision treatment methods (both surgical and contact lens), the dominant eye is corrected for distance vision to almost plano. The non-dominant eye, on the other hand, is corrected for near vision, usually to be myopic up to -3.0 D. Accommodation is thereby often diminished. The method aims to achieve optimal vision at distance and near range. Following the procedure, the brain must contend with two separate images with different levels of correction.

    According to scientific studies, only about 59-67 % of patients are able to successfully merge the two images to experience sharp binocular vision at near and distance range.1 Patients that tolerate the method are left with an uncorrected, compromised gap in the intermediate range, the so-called “Blur Zone.” In addition to the fuzzy image, it can also cause other side effects such as reduced contrast sensitivity and stereoacuity. Also, it often takes patients a long time to get used to merging the two images into one picture.

    Conventional monovision is a correction method with compromises. For a number of patients, it is not a suitable option.

  • Benefits
    PRESBYOND Laser Blended Vision - Customized

    Customized

    Generally speaking, conventional monovision methods utilize standard ablation profiles. In the case of PRESBYOND® Laser Blended Vision, they are customized for each eye individually because of the increased depth of field.

    Individualized ablations
    PRESBYOND Laser Blended Vision is a truly customized approach for treating presbyopic patients. It incorporates preoperative wavefront data to fine-tune the depth of field for each eye individually. The functional age of the patient’s eye is also factored in. Thereby, a personalized nomogram is created per eye for optimized target refraction. The monovision component can be preadjusted for the patient’s tolerance level. Also, different optical zone sizes can be selected to account for the patient’s pupil size.

     

    Ideal for a growing demographic
    As an optimized laser method for age-related loss of accommodation, PRESBYOND Laser Blended Vision is ideally suited for serving the needs of patients 40-60 years of age – a fast-growing demographic group interested in sophisticated options. It is also one of the least invasive methods for addressing presbyopia.

     

    Familiar procedure
    Following the same workflow as established LASIK procedures, PRESBYOND Laser Blended Vision combines the convenient binocular treatment planning of the CRS-Master® with the proven comfort and workflow of the MEL® 80 and the MEL 90 excimer laser from ZEISS.

    PRESBYOND Laser Blended Vision – All distances

    All distances

    Strictly in terms of the visual outcomes, PRESBYOND Laser Blended Vision transcends conventional monovision methods by offering clear sight at all distances: near, intermediate and far. Better yet, virtually all patients are freed from the need to wear reading glasses.1–4, 6


    Outstanding visual acuity

    By customizing each treatment individually, PRESBYOND Laser Blended Vision provides excellent visual sharpness for near and distance vision. Unlike conventional monovision methods, PRESBYOND Laser Blended Vision also offers good intermediate binocular vision in the Blend Zone. According to clinical studies, functional stereoacuity is maintained and there is virtually no loss of contrast sensitivity.1 Also, side effects such as multiple images in one eye are almost eliminated.


    An all-natural approach

    PRESBYOND Laser Blended Vision is a physiological solution and a true binocular method for treating presbyopic patients.


    Wide indication range

    PRESBYOND Laser Blended Vision is a proven and effective method for treating indications ranging from -8.0 D to +2.0 D, including emmetropic and astigmatic presbyopic patients (up to 2.0 cyl).

    PRESBYOND Laser Blended Vision - Immediate - Mel80

    Immediate

    What also clearly sets PRESBYOND Laser Blended Vision apart from other laser techniques is the immediate positive impact it offers patients and refractive surgeons alike – visually for the former, economically for the latter.1–4, 6


    Appropriate for most patients
    A key advantage of PRESBYOND Laser Blended Vision is that it is proven to be tolerated by more patients than conventional monovision. It is effective for treating up to 97%1 of all presbyopia-related forms of impairment as compared to only 59-67 %5 for conventional monovision. Even presbyopic patients with emmetropia and astigmatism can be treated. In fact, it has the potential to achieve a far greater success rate than any comparable treatment.1, 5


    A competitive edge
    PRESBYOND Laser Blended Vision allows refractive practices already using 
    MEL 80 or MEL 90 excimer laser and CRS-Master from ZEISS to significantly expand their LASIK repertoire and increase the patient base. For most patients, a positive effect is that they can read without glasses the very same day. As such, PRESBYOND Laser Blended Vision offers a decisive competitive advantage over LASIK practices only specializing in monovision treatment methods.
