“…Both our photopic and mesopic measures are comparable with those reported on the non-toric Bi-Flex 677TAY model [19,30]. Although CS measurements are difficult to compare due to their subjective nature and various scales used in reporting the results, we could not detect remarkably lower CS values at higher spatial frequencies as was seen with other TTIOLs [22,24,31].…”

“…The main advantage of our investigation might be the relatively long (one-year) follow-up period, which is rare among the scientific papers published on TTIOLs. Only four publications with similar longitudinal monitoring could be found in the literature [ 21 , 23 , 31 , 34 ]. Moreover, according to our knowledge, this is the first paper published on the refractive and visual outcomes following the implantation of the Bi-Flex 677MTY lens.…”

The current investigation evaluates the efficiency of the trifocal toric Liberty 677MTY intraocular lens (IOL) in correcting preoperative corneal astigmatism in cataract patients demanding spectacle independence. The retrospective evaluation included 28 eyes of 15 patients with preoperative corneal astigmatism of at least 1.0 Dioptre (D). All patients were followed up for one year postoperatively. Residual refractive errors and visual acuities at multiple distances were measured. Binocular visual acuity and contrast sensitivity defocus curves were plotted. Visual functions and patient satisfaction were assessed. The efficiency of astigmatism correction was determined using the vector analysis method. The mean spherical equivalent refraction (SEQ) improved from 2.72 ± 1.62 D to 0.10 ± 0.48 D. The cylindric refraction decreased from 1.18 ± 0.45 D to 0.16 ± 0.31 D. Vector analysis proved efficient astigmatism correction with a centroid of 0.10 ± 0.34 D at 161°. Ninety-two percent of eyes resulted within 0.5 D from the target refraction. Visual acuities were 0.1 logMAR or better from +1.0 to −3.5 D defocus values. Visual tasks could be performed without major difficulties. Our patients were highly satisfied. Refractive and visual outcomes with the investigated presbyopia-correcting toric IOL are predictable and the lens provides excellent trifocal vision.

“…52,53 Current multifocal IOL designs predominantly provide good visual outcomes, 54 with trifocal toric IOLs found to provide significantly better near vision than extended depth of focus IOLs while providing similar intermediate and distance VA outcomes. 55 Accommodating intraocular lens implants respond to ciliary body contraction, thus inducing accommodation, although current designs induce some inevitable side effects, such as limited amplitude of accommodation and a high rate of posterior capsular opacification. 56 New generation accommodating IOLs are now under investigation.…”

Presbyopia is a common age-related vision disorder characterized by a progressive inability to focus on near objects. If uncorrected or under-corrected, presbyopia can significantly impact patients' quality of life. Presbyopia represents an area of considerable unmet need due to its rising prevalence worldwide as the population ages, the high proportion of under-treated individuals in some parts of the world, and the limitations of currently available corrective methods. Progressive or bifocal spectacles are associated with peripheral blur, a restricted visual field and impaired depth perception, which have been linked to an increased risk of falls in the elderly. Contact lens options can be difficult to maintain due to the development of age-related dry eye symptoms and reduced manual dexterity. Other corrective methods involve surgical interventions that modify the optics of the cornea, replace the crystalline lens, or attempt to restore active accommodation. While patients undergoing surgery report satisfactory outcomes post-operatively, many of them eventually require reading glasses. Non-invasive therapies with novel mechanisms of action are currently being investigated; these include miotic agents and UNR844, a lipoic acid choline ester. In this narrative review, available evidence on presbyopia prevalence, quality of life impact and risk factors are described, with a focus on observational studies in nonclinical settings. The diagnosis pathway and patient journey in presbyopia are outlined, and various treatment options are analyzed. The data reviewed herein reveals significant gaps in the provision of vision correction for this common condition, with a paucity of effective, non-invasive treatment options broadly accessible to presbyopic individuals.

“… 13–15 The CS with trifocal IOLs has been shown to provide conflicting results when compared to found to extended depth of focus lenses. Gunderson 16 et al suggested comparable results between the two technologies, while Mencucci 17 et al showed that Symfony ERV IOL resulted in significantly better CS than AT LISA Tri 839 MP trifocal IOL. However, while comparing 3 different trifocal IOLs, Ribiero 8 et al did not find any statistically significant differences between groups for any of the spatial frequencies evaluated for photopic CS without glare (P > 0.05) 8 .…”

Purpose To evaluate the clinical outcomes and patient satisfaction after implantation of Optiflex Trio, a new trifocal intraocular lens (IOL) following cataract surgery. Methods Patients undergoing phacoemulsification for age-related cataracts and who satisfy the eligibility criteria underwent bilateral implantation with Optiflex Trio trifocal IOL. At follow -up visits of 1, 3, 6, and 12 months, binocular uncorrected and corrected distance, intermediate and near visual acuity, reading performance, contrast sensitivity (CS) and patient satisfaction for dysphotopsia and spectacle independence were evaluated using questionnaires. Results A total of 54 eyes from 27 patients with mean age of 66.30±7.48 years were included in the study. At 12 months, 78% (n = 21) patients had binocular cumulative UDVA of 20/20 or better. Post-op SE refraction accuracy was within ±0.50 D for 93% (n = 50) eyes, and refractive cylinder accuracy was within ≤0.50 D in 94% (n = 51) eyes. The mean binocular UNVA was 0.01±0.05 LogMAR, and the mean UIVA at 60 and 80 cm was 0.07±0.06 and 0.03±0.05 LogMAR, respectively, at 12 months. Reading speeds at 40, 60 and 80 cm showed improvement overtime. No patient had complained of severe dysphotopsia, and none of the patients required glasses for any activity. No eye underwent YAG-laser capsulotomy for significant PCO at the end of mean follow-up. Conclusion After 12 months, Optiflex Trio trifocal IOL provided a complete visual restoration with good visual quality outcomes in terms of uncorrected distance, intermediate and near visual acuity. The incidence of dysphotopsia was low, and spectacle independence was high, resulting in good patient satisfaction. Trial Registry CTRI/2019/10/021647 ( www.ctri.nic.in ).
