FluidVision Accommodating Intraocular Lens.

Panel tests of color vision (eg FM100-Hue test) lack a common quantitative method for the scoring of cap arrangements. Methods: However, no significant difference was found in the degree of the tilt between the two types of IOLs throughout the observation periods. Of the 24 subjects, 15 failed both D-15 and the FALANT tests. Without clinically substantiated potential risks, these patients should experience the benefit of overall better quality of vision, reduced glare disability at least in some conditions, and better protection against retinal phototoxicity and its associated potential risk for AMD. Real ray tracing calculated the exact geometry of custom IOLs to provide the minimum wavefront error, going beyond simple diopter information. ... 1,4,24,25 Although there are anecdotal data available to support these assumptions, the majority of scientific findings on yellow-tinted blue light-filtering IOLs show no clinically significant differences in visual performance under natural lightning conditions compared with conventional UV light-filtering IOLs. Contrast sensitivity was measured using the Holladay automated contrast sensitivity test with 5.0-mm artificial pupil at 3 and 6 cycles per degree at optimal focus and at several defocus levels. The results suggest a protective effect.

That of pseudophakic eyes implanted with non-UV IOLs and aphakic eyes corresponded to that of infants.

Corneal aberrations were measured with the CSO Eyetop topographer, and ocular aberrations were measured with a Hartmann-Shack aberrometer for a 6-mm pupil. Crystalens Advanced Optics (AO) Accommodating IOL. The 3 measurements were the modulation transfer function values (MTF cutoff); objective depth of focus, which was computed as the focus range at which Strehl ratio did not fall below 50% of the maximum; and the objective scatter index. Regarding scotopic vision, no clinically significant impairment is to be expected from blue-light-filter lenses because maximum excitation in scotopic light reception occurs at 507 nm whereas the light transmission of blue-light-filter lenses is 85%--this is higher than that of a child's crystalline lens. 2007 Apr;33(4):603-10. doi: 10.1016/j.jcrs.2007.01.009. The depth of focus and the myopic shift (shift of optimum focus toward more myopic values at lower spatial frequencies) were determined. Diagnosis of Defec-tive Colour Vision, Birch J. In 25 of the patients (50 eyes) the following parameters could be assessed 3 months after surgery: visual acuity, refraction, contrast sensitivity, pupil size, wavefront errors and decentration and tilt using a newly developed device. In this prospective study, wavefront measurements of 21 patients after implantation of a spherical IOL (AMO AR40e) in 1 eye and an aspherical, To evaluate and compare optical and visual quality of eyes implanted with spherical and aspheric intraocular lenses (IOLs). 2013 Nov-Dec;76(6):386-90. doi: 10.1590/s0004-27492013000600016. Intraocular lenses (IOLs) that block both ultraviolet and blue wavelength light (<500 nm)were introduced in the 1990s. Patients' satisfaction was parallel, the mean VF-14 scores in Akreos Adapt AO group was 98.57 (2.51) and Tecnis ZA9003 group was 97.18 (5.46) (p = 0.501).

We evaluated findings related to ocular and systemic adverse effects.Two review authors independently screened abstracts and full-text articles, extracted data from eligible RCTs and judged the risk of bias using the Cochrane tool. Thus, visual acuity, contrast sensitivity, refraction and defocus curve show the same good results at large pupil sizes compared with small pupil sizes. The AT LISA 809M/MP was the first preloaded multifocal MICS IOL. No author has a financial or proprietary interest in any material or method mentioned. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2017, Issue 9); Ovid MEDLINE; Ovid Embase; LILACS; the ISRCTN registry; ClinicalTrials.gov and the ICTRP. There was no statistically significant difference in baseline characteristics between groups. The mean amount of decentration was 0.2 mm±0.2 mm in the horizontal and vertical directions.

Sprague-Dawley rats reared under cyclic light were exposed continuously to diffuse blue light (400-480 nm) at 0.64 W/m2 for 3 or 6 h after 22 h of dark adaptation. A long-term population-based clinical trial would determine whether a blue light-absorbing IOL can reduce the risk for or progression of age-related macular degeneration. Only two of the studies had a trial registry record and no studies referred to a published protocol. Cataract surgery was revolutionised by the introduction of modern intraocular lenses in the late 1940’s. Setting:

It is generally postulated that better visual outcome is achieved after phacoemulsification with aspheric foldable IOL. to evaluate the effect of the residual refractive error on uncorrected distance visual acuity (UCVA) after cataract surgery using spherical versus aspheric intraocular lenses (IOL). Final postoperative examination was performed at the end of 18 months.

Results: … There were no statistically significant differences in central macular thickness between the 2 IOL groups (P=.712).

Since then, the potential benefits and harm from blocking blue light has been debated. In comparison to a spherical IOL, the aspherical Tecnis IOL reduced Z(4)(0) and 4th-order RMS significantly for pupil diameters of 3 to 6 mm, whereas total HOA RMS was only significantly reduced for a pupil diameter of 6 mm. When compared with a structurally (platform and material) similar spherical IOL (Rayner 620H), aspheric IOLs (Rayner 920H) appear to significantly reduce HOAs and yield better levels of contrast sensitivity under photopic conditions. After uneventful phacoemulsification, 42 and 20 eyes were implanted with the AcrySof IQ aspheric lens and the SA60AT, respectively. In addition to other findings, visual acuity, color perception, and contrast sensitivity were recorded. It is designed so as to reduce the loss of light energy resulting from any diffractive system.
It has prolate anterior and posterior surfaces and uniform thickness and refractive power from the lens' center to its edge. The AcrySof IOL (model SA60AT) is an ultraviolet-absorbing acrylic foldable single-piece lens. The tinted lens group showed a higher incidence of transient inflammation than the standard lens group (p=0.03) but the rates of nontransient sequelae (posterior synechiae, iris synechiae, membranes formation, capsule, or IOL opacification) were similar (66% versus 47%; p=0.11).

We judged approximately two-thirds of the studies to have a high risk of bias in domains relating to 'blinding of participants and personnel' (performance bias) and 'blinding of outcome assessment' (detection bias).We found with moderate certainty, that distance BCVA with a blue-light filtering IOL, at six to 18 months postoperatively, and measured in logMAR, was not clearly different to distance BCVA with a non-blue-light filtering IOL (mean difference (MD) -0.01 logMAR, 95% confidence interval (CI) -0.03 to 0.02, P = 0.48; 2 studies, 131 eyes).There was very low-certainty evidence relating to any potential inter-intervention difference for the proportion of eyes that developed late-stage AMD at three years of follow-up, or any stage of AMD at one year of follow-up, as data derived from one trial and two trials respectively, and there were no events in either IOL intervention group, for either outcome. The AcrySof IQ lens (model SN60WF) is a single-piece IOL with proprietary blue light filtering chromophores that filter light in a manner that approximates the crystalline lens in the 400-475 nm blue light wavelength range. No statistically significant differences were found between the BSCVA of the AcrySof IQ IOL (0.023 +/- 0.004 logMAR) and AcrySof Natural IOL (0.031 +/- 0.003 logMAR) (P = .15). The mean coma was 0.13 microm+/-0.07 (SD) in the younger phakic group, 0.18+/-0.08 microm in the older phakic group, and 0.16+/-0.08 microm in the pseudophakic group; the difference between the 2 phakic groups was statistically significant (P< .005). The results give some suggestions for further studies. Mean UCVA and BCVA were 20/25 ± 8 letters and 20/18 ± 4 letters, respectively.

The agreement between the Ishihara and D-15 tests was 62.5%. J Current Glau Prac 2013;7(2): 54-57.

Difference at the CS was statistically significant at the examination with Landolt circles too, for p < 0.05. Tests were performed before and after IOL implantation at 1, 3, and 6 months. Another animal fed beta-carotene (7.5 mg daily) over a period of 3 months has been exposed to blue light at several levels of oxygenation.

For protan and deutan thresholds no differences were found. Both groups show considerable interindividual variation on all measures.
