Challenges in corneal refractive surgery

Customized visual freedom
Clinical Challenge

Plan for good visual acuity at all distances

Selecting an option that enables good visual acuity at all distances has become a common goal among patients considering corneal refractive surgical treatment who want to see clearly at far for driving and at near-to-intermediate when using their smartphones or computers. Not all refractive surgical options for presbyopia consistently meet this need.1,2

Conventional monovision corrects one eye for distance vision and the fellow eye for near vision. It can result in two distinct points of focus and leave an uncorrected gap, which is hard for the brain to adapt to the blurred image in the intermediate distance, the so called “Blur Zone”.3 Studies show that only 59% to 67% of patients could tolerate the anisometropia created by contact lens monovision.3 Multifocal LASIK approaches can provide good near and intermediate vision, but they can reduce distance vision and contrast, induce an undesirable increase in corneal aberrations, and may lead to glare and halos.2,4

Clinical Solution

Achieve clear full range of binocular vision through Laser Blended Vision

Laser Blended Vision is a LASIK-based procedure for correcting presbyopia that induces micro-anisometropia (≤1.5 D) and controls spherical aberration. Spherical aberration is a naturally occurring aberration that helps the brain to combine the images from both eyes into clear binocular vision, preserving contrast sensitivity and most of the stereoacuity, while maintaining the accommodation capacity of the natural lens.5,6 The enhanced depth of field from spherical aberration extends the range of vision in each eye, creating a “blend zone”, rather than a “blur zone”, in the intermediate range. Combining the vision from the two eyes naturally gives a clear continuous range of vision from near through intermediate to far.7,8

ZEISS Solution

PRESBYOND as a customized corneal refractive solution for presbyopia treatment

PRESBYOND® Laser Blended Vision from ZEISS is a customized solution planned with a software module in the Refractive Workplace from ZEISS, performed with the MEL® 90 from ZEISS, and uses a non-linear aspheric ablation profile that creates a continuous refractive power gradient over the entire corneal optical zone.9 It offers patients good quality vision with reduced dependence on glasses at all distances.10 Results from studies of patients treated with PRESBYOND show a high acceptance rate of up to 97% with a full range of good uncorrected visual acuity from near to far. These outcomes are achieved without loss of contrast sensitivity and with no significant reduction in stereoacuity.11, 13

PRESBYOND LBV offers non-cataract patients a safe and effective treatment option for presbyopia, providing the chance of spectacle independence while avoiding intraocular surgery. Our recent studies have shown that patients experience a high level of spectacle-free reading ability postoperatively, which results in improved reading speeds and high patient satisfaction.
