“…The only downside was the subjective visual acuity regarding nighttime driving due to halos and other optical phenomena [74]. Similar outcomes have been reported in highly myopic patients implanted with the Acrysof ReSTOR SN60D3 (Alcon) [75]. Good visual outcomes for the trifocal Liberty Bi-Flex 677MY (Medicontur Medical Engineering Ltd., Hungary) were published in 2019 by Gyory The visual acuity in all distances for trifocal and panfocal IOLs was shown in 2018 by comparing the trifocal AT LISA (Zeiss, Germany) with the panfocal PanOptix (©Alcon, USA).…”

Purpose: To understand the nature of presbyopia and the various pseudophakic treatment methods available. Findings: Presbyopia is a normal and unavoidable age-related condition that results in the progressive worsening of the ability to focus clearly on close objects. This loss of accommodation affects near-vision tasks and if untreated can impact quality life. Presbyopia can easily be treated with glasses and contact lenses, but developments in presbyopiacorrecting intraocular lenses for implantation during refractive lens exchange or cataract

“…Es wird vermutet, dass vorbestehende Netzhautveränderungen zu verminderten funktionellen Ergebnissen und einem erhöhten Auftreten von Nebenwirkungen führen können. Einzelne Studien konnten zwar zeigen, dass multifokale Optiken auch bei hoch myopen Patienten zu guten funktionellen Ergebnissen führen können, jedoch ist dies im Einzelfall schwer vorherzusagen [ 14 ]. Die Reversibilität ist insbesondere deswegen von Vorteil, weil trifokale Optiken oft bei jüngeren Patienten eingesetzt werden.…”

Reversible Trifokalität durch das Duett-Verfahren

Zusammenfassung Funktionelle Ergebnisse und das Auftreten von Nebenwirkungen (insbesondere photischer Phänomene) können beim Einsatz multifokaler Intraokularlinsen (IOL) schwer vorhergesagt werden. Des Weiteren können Patienten im Laufe des Lebens Erkrankungen entwickeln, bei denen eine multifokale Optik von Nachteil sein kann. In diesen Fällen ist ein Austausch der IOL die einzige Therapieoption. Die Implantation einer monofokalen oder monofokal-torischen IOL in den Kapselsack und einer additiven trifokalen IOL in den Sulcus ciliaris in einer als Duett-Verfahren bezeichneten Operation ermöglicht Trifokalität, die bei Bedarf vergleichsweise einfach wieder rückgängig gemacht werden kann.

“…On the contrary, newer lens formulas and adjustments/transformations are now available to reduce postoperative predictive error in high myopes [29,30]. Furthermore, the levels of satisfaction and spectacle independence experienced by high myopes were reasonably high after implantation of multifocal or trifocal intraocular lens [15,31]. Since these outcomes enhance the con dence of high myopes, they are more inclined to schedule cataract surgery at a younger age.…”

Background: To create an anterior chamber depth (ACD) regression model for adult cataract surgery candidates from China, and to evaluate the distribution of their ocular biometric parameters.Methods: The ocular biometric records of 28,709 right eyes of cataract surgery candidates who were treated at Aier Eye Hospitals in nine cities from 2018 to 2019 were retrospectively analyzed. All measurements were taken with IOLMaster 700. We included patients who were at least 40 years old and were diagnosed with cataract.Results: The mean age of the patients was 68.6 ± 11.0 years. The mean values recorded were as follows: axial length (AL), 24.17 ± 2.47 mm; mean keratometry (Km) value, 44.09 ± 3.25 D; corneal astigmatism (CA), 1.06 ± 0.98 D; ACD, 3.02 ± 0.45 mm; lens thickness (LT), 4.52 ± 0.45 mm; central corneal thickness (CCT), 0.534 ± 0.04 mm; and white to white (WTW) corneal diameter, 11.64 ± 0.46 mm. The proportion of patients with long axial length (AL >25 mm) decreased with age. ACD, LT, AL, Km, WTW, and age were correlated. In the multivariate regression analysis of ACD, which included LT, AL, WTW, sex, Km, CCT, and age, there was a reasonable prediction with adjusted R2 = 0.629.Conclusions: The results show that high myopes are inclined to schedule cataract surgery at a younger age. LT and AL were found to be important factors that affect ACD. This study provides reference data for cataract patients from China.

Visual results after implantation of a trifocal intraocular lens in high myopes

Abstract: Implantation of a trifocal IOL in highly myopic eyes with low IOL power (0.0 to 10.0 D) provided satisfactory short-term visual and refractive outcomes; however, results were not as good as those obtained in eyes with higher dioptric IOL power.
