“…No presente estudo, 75% dos pacientes do grupo multifocal tiveram J1 e 100% tiveram AV para perto, melhor ou igual a J3. Enquanto que no grupo monofocal, a AV para perto em 10% foi J1 e 70% até J3, dados concordantes com outros autores na literatura (5)(6)(8)(9) . Apesar da visão para perto de J1, muitos pacientes do grupo multifocal necessitavam de óculos, pois a leitura tornava-se cansativa, principalmente nos pacientes acima de 70 anos.…”

Objetivo: Comparar a acuidade visual de longe e perto de pacientes submetidos à facoemulsificação binocular não simultânea com implante de lentes multifocais ou monofocais. Métodos: Foram selecionados 20 pacientes com lentes multifocais bilaterais e outros 20 pacientes com lentes monofocais também bilaterais, com acuidade visual sem correção melhor ou igual a 0,63 (20/30), medidos separadamente, nos três primeiros meses de pós-operatório. Foi medida a acuidade visual para longe e perto com e sem correção e testes de sensibilidade ao contraste e ofuscamento. Resultados: A acuidade visual sem correção para longe no grupo das monofocais teve média de 0,82 (DP± 0,16) e no grupo das multifocais, 0,94 (DP±0,12), valor de p 0,001. Os dois grupos de lentes tiveram visão com correção para longe igual a 1. No grupo das multifocais, 75% tiveram J1 e 100% tiveram J3 ou melhor sem correção. No grupo das lentes monofocais, 10% tiveram J1 e 70% tiveram J3 ou melhor sem correção. Não houve diferença significante na avaliação com o teste de sensibilidade ao contraste entre os grupos pesquisados. No teste de ofuscamento, os dois grupos tiveram redução da visão, que foi mais acentuada no grupo dos pacientes com lentes multifocais. Conclusão: A acuidade visual para longe com correção nos pacientes com implante multifocal foi semelhante a dos pacientes com implantes monofocais, embora a acuidade visual para perto no grupo em que foi implantado lente multifocal foi bastante superior ao grupo da lente monofocal. A sensibilidade ao contraste manteve-se semelhante nos dois grupos, já o ofuscamento ("glare test") no grupo multifocal foi maior que no grupo monofocal.

“…Patients reported significant improvements in these symptoms by the 6 th postoperative month, probably due to neural adaptation (10) . Objective and subjective assessments showed that patients with bifocal and multifocal IOLs were more independent from glasses, with a better visual outcome and higher patient satisfaction for far, intermediate and near vision (9,12,13,16,19) . Bifocal IOLs can be a cost-effective alternative for patients in poor financial condition as they reduce the need for glasses after cataract surgery (5) .…”

“…A questionnaire (Appendix 1) with 47 questions assessing patient satisfaction, the need for eye glasses, and quality of life was administered to all patients by the same examiner. The questionnaire was developed by combining 3 questionnaires that had been previously validated in a pilot project (5,7,9) All patients underwent surgery in both eyes. All patients provided their Free and Informed Consent, and the study was approved by the Research Ethics Committee (REC) of the Federal University of São Paulo.…”

The authors declare no conflict of interest. ABSTRACT 05). As to the comparison of monofocal lenses with bifocal and multifocal lenses, the near vision without correction was considerably lower in patients with monofocal lenses (Z test p< 0.001). The patients with monofocal lenses without correction presented a much lower capacity of reading newspapers or books and as far as manual work than the ones with bifocal and multifocal lenses (Z test, p<0.001). Conclusion: The result of this study shows that the patients who received the bifocal and multifocal lenses had a remarkable improvement in their visual

Purpose To compare best-corrected visual acuity (BCVA) and contrast sensitivity (CS) under different levels of illumination in patients who had monofocal and multifocal intraocular lenses (IOLs) and to establish the effect of different lighting conditions on vision in the two groups of patients. Methods We retrospectively reviewed 27 patients who underwent phacoemulsification for age-related cataract and IOL implantation of either monofocal (SI30NB; n ¼ 10, 37%) or multifocal (SA40N; n ¼ 17, 63%) IOLs. Binocular distance and near BCVA and CS were tested using logMAR and Pelli-Robson charts that were externally illuminated with 20, 200, 400 and 1600 lux, and were compared using repeated-measures analysis of variance. A questionnaire was administered to establish the lighting preference in the two groups and the effect of lighting conditions on their vision. Results Binocular distance and near BCVA and CS significantly increased with increasing illumination from 20 to 200 lux in the monofocal (mean ¼ 0.04 vs -0.07, P ¼ 0.006; 0.37 vs 0.26, P ¼ 0.002 and 1.47 vs 1.60, P ¼ 0.01) as well as in the multifocal group (mean ¼ 0.03 vs À0.12, Po0.001; 0.38 vs 0.23, Po0.001 and 1.47 vs 1.61, P ¼ 0.002). No significant difference in BCVA or CS was found between the two groups at any of the four illumination levels. Both groups had similar lighting preference, but 43.8% of patients in the multifocal group experienced subjective worsening of their vision in bright outdoor lights. Conclusions Distance and near BCVA and CS improve with increasing illumination in patients with monofocal and multifocal IOLs, but remain comparable in the two groups under common levels of indoor illumination. Patients with multifocal IOLs may experience worsening of their vision in bright outdoor lights.

AMO array multifocal lens versus monofocal correction in cataract surgery

Abstract: The results of this study indicate high patient satisfaction with the Array multifocal IOL and greater functional independence from spectacle wear, by objective and subjective patient measures, than with the monofocal IOL.
