Reading ability with 3 multifocal intraocular lens models

“…We used the Radner Reading Charts, which offer a German version. For the general comprehension of reading performance and the clinical application of reading tests, it is important to distinguish between the maximum reading speed, which is achieved at large print sizes and which can be used as a diagnostic clinical test, 4,11,12,18,43,44 and the highest reading speed with smaller print sizes, as used in this study. Assessing reading speed using smaller print sizes of logRAD 0.4 is particularly relevant because it simulates everyday life situations such as reading newspapers, books, and magazines, 26 the text of which are generally printed at 0.4 logRAD.…”

“…8 Early trials with multifocal IOLs were disappointing because of poor surgical techniques that induced astigmatism and caused IOL decentration. 6,[8][9][10][11][12][13][14] Moreover, many patients reported reduced contrast sensitivity and a high incidence of halos and glare. 11,[15][16][17][18][19] The development of the Array SA40N (AMO) was a major step toward a safe and effective treatment for presbyopia and cataract, and high levels of patient satisfaction have been reported.…”

[20][21][22][23][24][25][26] However, second-generation multifocal IOLs, including the Tecnis ZM001 (AMO) and the AcrySof ReSTOR SA60D3 (Alcon), had better performance, providing more independence from glasses and a reduction in glare and halos.…”

Depth of focus in eyes with diffractive bifocal and refractive multifocal intraocular lenses

“…[18][19][20] For a 4.0 mm pupil, the Array focuses 50% of incoming light on distance, 35% on near, and 15% on intermediate foci. 21 Like the Acri.Twin IOLs, the Pharmacia 811E is a diffractive bifocal lens, but with more even light distribution of 60% focused on distance and 40% focused on near and loss of light caused by higher orders of diffraction. 22 In addition to good distance vision, the 811E IOL provides good near visual acuity and reading performance.…”

Visual and optical performance with hybrid multifocal intraocular lenses

“…To achieve multifocality, these lenses use either the principle of diffraction and/or refraction and they may be divided into three groups: 11 1. diffractive multifocal IOLs 2. refractive multifocal IOLs 3. hybrid multifocal IOLs.…”
