“…No entanto, as últimas apresentaram alguns efeitos adversos como a redução da sensibilidade ao contraste e visão de halos (49) . Num estudo de 120 olhos, realizado na Alemanha, com desenho prospectivo e randomizado, Hütz mostrou que a Tecnis ZM001(AMO) teve o melhor desempenho nas diferentes condições de luminosidade comparada com a Restor SA60D3 (Alcon) e a SA40N (AMO) (50) . A indicação de TCR na presbiopia parece ter bom perfil de segurança, necessitando-se salientar que na decisão pela técnica e escolha da LIO multifocal devese levar em consideração as características e hábitos do paciente, lembrando das limitações em termos de qualidade visual em baixa luminosidade e tarefas como condução de veículos à noite, sendo transparente na informação dos possíveis benefícios e restrições.…”

“…Modern reading charts, such as the highly standardized Radner Reading Charts, allow the simultaneous evaluation of reading acuity and reading speed and thus provide more detailed information about visual impairment than traditional near vision tests (e.g., Jaeger, Nieden, Parinaud). In addition, such reading charts provide increased accuracy (6) for the evaluation of near visual performance and have become a valuable clinical tool for pre-and postoperative assessment and for visual rehabilitation (7)(8)(9)(10)(11)(12) . International standards should be applied to the evaluation of reading performance.…”

Purpose: To develop 27 short sentence optotypes for the Portuguese version of the Radner Reading Charts. Methods: Thirty-four Portuguese sentences were constructed following the con cept of the Radner Reading Charts to obtain highly comparable sentences in terms of lexical difficulty, syntactical complexity, word length, number of syllables, and position of words. A long text (106 words) at the 5 th grade reading level was also tested to assess the validity of the reading speeds obtained with the short sentences. The short sentences and long text were tested in 50 volunteers with similar educational backgrounds (mean age 30.98 years ± 6.99 years, range 19-47 years). Reading speeds were measured with a stop-watch and reported as words per minute (wpm). The reading time for each of the short sentences to be selected for the chart was defined as falling within the range of the mean ± 0.40 × standard deviation (SD). Results: The overall mean reading speed for each of the short sentences was 235.43 ± 36.39 wpm. The 27 sentences with a mean between 220.8 and 250.0 wpm (overall mean ± 0.40 × SD) were selected for construction of the reading charts. The mean reading speed for the long text was 212.42 ± 26.20 wpm. Correlation between the selected short sentences and long text was high (r =0.86). Reliability analysis yielded an overall Cronbach's alpha coefficient of 0.97. Conclusions:The 27 short Portuguese sentences were highly comparable in terms of syntactical structure, number, position and length of words, lexical difficulty, and reading length. This reading test can overcome the limitations of the current tests for homogeneity and comparability, reducing subjectivity in the evaluation of the functional outcomes of medical and surgical ophthalmologic treatments.

“…One option to increase the depth of the focus allowing distance and near vision is monovision, that is, treating the dominant eye to provide distance vision and the nondominant eye to provide near vision. 1 Predicting success with this approach has proved to be difficult, as not all patients adapt to monovision due to the inherent loss of depth perception. 2 Another option is the implantation of an accommodating IOL.…”

During the past years, the wish to become independent of spectacles has been growing among cataract and presbyopic patients due to many factors, such as the increase in near visual demands, the aesthetic need for a spectacle-free image and ageing of refractive surgery patients, among others. This review assesses recently published studies that analyse visual and optical performance through different metrics of eyes implanted with multifocal intraocular lenses (IOLs), particularly hybrid IOL designs. The published evidence suggests that hybrid multifocal IOLs provide very good outcomes in a number of visual and optical performance parameters. Patients implanted with this type of IOL obtain a satisfactory full range of visual functions, including patients of particular characteristics such as highly ametropic or post-LASIK.

Reading ability with 3 multifocal intraocular lens models

Abstract: Under bright-light conditions, second-generation multifocal IOLs provided better reading performance than the Array SA40N IOL. However, when tested under low-light conditions, patients with the Tecnis ZM001 IOL had the best reading acuity and reading speed.
