At 3 months postoperative, the mean UCVA in the IQ and SA60AT groups was 0.25 (SD 0.26) and 0.30 (SD 0.27), respectively, and BSCVA was 0.10 (SD 0.16) in both groups. To evaluate the possible side effects and potential protection 5 years after implantation of an intraocular lens (IOL) with a blue-light filter (yellow tinted). The Berson test is recommended to distinguish the XL from AR achromats.

Prespecified secondary outcomes included postoperative contrast sensitivity, colour discrimination, macular pigment optical density (MPOD), proportion of eyes with a pathological finding at the macula (including, but not limited to the development or progression of AMD, or both), daytime alertness, reaction time and patient satisfaction. Results show spherical aberration can be significantly reduced with aspheric IOLs. Objectives: Since then, the potential benefits and harm from blocking blue light has been debated. There were also no significant between-group differences under photopic or scotopic conditions at any spatial frequency studied.

Both groups show considerable interindividual variation on all measures. The region of accommodation at which eyes achieved a corrected visual acuity of 20/29 or 20/40 was greater in phakic eyes than in pseudophakic eyes in the 40s and 50s age groups (P

Monocular defocus curve and distance, intermediate, and near visual acuity outcomes did not differ significantly between groups. There were 24 male subjects with a color vision deficiency, as defined by the Ishihara test, who participated in this study. Contrast sensitivity was measured using 2 computerized tests (vertical sine-modulated gratings and circular sine-modulated patterns) with cycloplegia and a 5.0 mm artificial pupil under photopic conditions at optimum refractive correction and at several defocus levels.

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.

The purpose of this study was to measure luminance contrast sensitivity and color vision thresholdfs in normal subjects using a blue light filter lens and transparent intraocular lens material.

enhanced square edge and aberration-neutral optic technology. Much of the evidence for photoprotection is theoretical or based on observations in cell culture or animal experiments, with little clinical information to date. Dr. Trueb suggested that this large sample size should properly address questions of …

II. However, the limited possible reduction of total HOAs, even perfectly positioned custom aspheric IOLs, may be a reason for the unclear results in studies assessing the potential benefit to visual performance of currently used aspheric IOLs. Purpose:

After 5 years, there were no significant differences in color perception, scotopic contrast sensitivity, or photopic contrast sensitivity between the blue light-filtering (yellow-tinted) IOL and the IOL with a UV-light filter only (untinted). Neither author has a financial or proprietary interest in any material or method mentioned. Private eye clinic in Germany.

Such a quantitative score can be used to establish relationships with other visual functions or experimental conditions. Sunlight exposure has been suggested as a cause of AMD. Search methods: The enVista intraocular lens is a hydrophobic, single-piece ultra-violet absorbing posterior chamber intraocular lens designed to be free of spherical aberration. Photoreceptor cell apoptosis is seen early after the retina is damaged by blue light.

Patients were tested unilaterally to detect CPRG defect using Ishihara pseudoisochromatic plates and the Farnsworth D-15 test.

The lens was designed with a proprietary achromatic diffractive surface to correct chromatic aberration and a unique echelette feature to extend the range of vision, including far, intermediate, and near, while maintaining the corneal spherical aberration compensation. However, the published studies clearly state that the use of blue-blocking IOLs is not detrimental in visual acuity, color perception, and contrast sensitivity. Our objective is to address these issues by providing an updated clinical perspective based on the results of the most recent studies. The phaco probe is used more for aspiration than for cutting.

The lens was designed with a proprietary achromatic diffractive surface to correct chromatic aberration and a unique echelette feature to extend the range of vision, including far, intermediate, and near, while maintaining the corneal spherical aberration compensation. The TECNIS Toric IOL (models ZCT150, ZCT225, ZCT300, ZCT400, ZCT450, ZCT525, ZCT600) is made from ultraviolet light-absorbing material that compensates for corneal spherical aberrations and corneal astigmatism. On the basis of these data, it is predicted that about 5% of dichromats will be mis-classified by the Adams desat D-15 whilst under 0.1% will be mis-classified by the standard D-15. Data collection and analysis: The Sulcoflex Toric IOL (model 653T) is a hydrophilic acrylic supplementary IOL with a unique posterior concave surface designed to minimize the possibility of interaction with the primary IOL. Methods: Photopic and mesopic contrast sensitivities (with and without glare) were significantly higher in Group A at most spatial frequencies.

Although aspheric aberration-free IOLs are designed to correct the intrinsic spherical aberration of the IOL, 11 aspheric aberration-correcting IOLs are aimed at compensating for the corneal spherical aberration of an average pseudophakic eye with the goal of a leaving minimal postoperative total spherical aberration. The T-flex Aspheric Toric lens (models 573T and 623T) features a closed looped haptic configuration progressively absorbs forces generated within the contracting capsular bag to offer excellent centration with rotational, torsional and directional stability. The add power of +2.5 D is designed to provide optimal vision at 53 cm for activities requiring more intermediate. Measuring the corneal asphericity allows estimation of postoperative ocular spherical aberration. Selection criteria: All patients had clear cornea phacoemulsification surgery, 61 patients (61 eyes) were implanted with aspheric Akreos Adapt AO IOL and 51 patients (51 eyes) were implanted with aspheric Tecnis ZA9003 IOL.

There was no statistically significant difference between eyes in uncorrected and best-corrected visual acuity at 1 and 3 months after surgery. The results in this review were used in an attempt to understand whether there is a visual and/or optical benefit of implanting aspheric IOLs over implanting spherical IOLs. The potential benefits and possible side effects of these different innovations emphasise the importance of assessing the evidence for their clinical utility, allowing the surgeon and the patient to weigh-up the risk benefit ratio and make an informed decision. Results of quantitative analysis performed on three factors confirmed these findings and indicated the Blu Blockers and Vuarnet SWAF's caused moderate and moderate-to-severe levels of color confusion, respectively. Uniocular average photopic contrast sensitivity was 1.36 ± 0.19, 1.43 ± 0.18 and 1.46 ± 0.15 log units for clear lens, yellow lens and orange lens, respectively (statistically not significant; p = 0.076). We summarised the overall certainty of the evidence using GRADE. The standard lens group consisted of 38 eyes (31 patients; age 11 months to 15 years). To evaluate potential differences in the quality of vision after implantation of a blue light-filtering intraocular lens (IOL) and an ultraviolet (UV) light-filtering IOL. Design: No author has a financial or proprietary interest in material or method mentioned. The mean age of the patients was 80 years +/- 8.1 (SD). The FINEVISION Trifocal Optic (Micro F) was the first trifocal diffractive IOL. Methods: Central colour contrast sensitivity was measured with a computer graphics system along the protan, deutan and tritan axes. We have undertaken further analysis to determine whether ocular exposure to violet light (400 to 450 nm), blue light (400 to 500 nm), or all visible light (400 to 700 nm) was associated with AMD. The strength of positive association only between UIVA and dynamic visual acuity increased as the velocity increased, but not UDVA or UNVA. Vision-related quality of life questionnaires based on VF-14 in Malay language was completed by each patient. Ultraviolet or blue-filtering intraocular lenses: What is the evidence?

Conclusions: The Natural IOL reduces ultraviolet and blue-light exposure to the retina, mimicking the filtering normally provided by the human crystalline lens. The aim of this study is to compare the safety and efficacy of a relatively low cost indigenous IOL (Acriol EC) with an imported aspheric IOL (AcrySof IQ).

Scotopic contrast sensitivity in the presence or absence of glare was measured using the Mesotest II (Oculus GmbH). Conclusions based on these analyses are conservative because, with exception of the GCRI, color adaptation effects were not taken into account. That of pseudophakic eyes implanted with non-UV IOLs and aphakic eyes corresponded to that of infants. To compare ocular higher-order aberrations (HOAs) in eyes with aspheric intraocular lenses (IOL) and in phakic eyes. 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. The study included 51 eyes of 33 patients who underwent cataract surgery.

One group received a 3-piece hydrophobic acrylic IOL with 12.5 mm poly(methyl methacrylate) haptics and the other, a 1-piece hydrophobic acrylic IOL with 12.5 mm haptics. There was no significant difference between groups in the percentage of patients with measurable tilt and decentration and of patients without measurable tilt and decentration (P = .956).

The study included 27 patients (30 eyes) after cataract surgery, in whom contrast sensitivity in the setting of different illumination conditions at spherical defocus of different degree and sign was tested.

The optics of these aspheric IOLs are conical in shape with improved optical properties leading to less pseudo accommodation, thus increasing the influence of defocus. A technique is described that combines the principles of chop in situ and cracking for division of leathery, hard cataracts.

The number of participants ranged from 13 to 300, and the follow-up period ranged from one month to five years. Twenty-one patients experienced some difference between their two eyes in distance vision and 23 noticed differences in near vision.

However, with the anomalous trichomats, more crossings were made on the Adams desat D-15, particularly by the milder anomals, and a diagnosis was possible in more cases. To determine whether implantation of the AcrySof Natural intraocular lens (IOL) worsened the severity of existing color deficit in congenital partial red–green color deficient individuals (CPRG). We describe a variation of stop and chop phacoemulsification.
