Array multifocal intraocular lens in a charity hospital training program

Abstract

Implantation with the multifocal IOL may be a cost-effective option for low-income patients because it reduces the need for spectacles after cataract surgery.

Evaluation of life quality of patients submitted to cataract surgery with implants of monofocal, bifocal and multifocal lenses

“…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) . Note that it would be appropriate to apply the questionnaire more than once and at different dates.…”

“…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.…”

“…However, monofocal IOLs have limitations as they only provide good visual acuity in a single focal plane, either far or near. Patients usually need glasses to perform activities that require a better visual acuity in the focal plane not corrected by the chosen IOL (4,5) . Multifocal IOLs provide better visual performance than monofocal IOLs, as they improve both near and far visual acuity with little or no correction.…”

Resultados do implante bilateral de lente intra-ocular multifocal SA-40N no Hospital de Olhos de Minas Gerais

“…Na maioria dos casos, monofocal (1)(2)4,7) . Esse tipo de lente apresenta uma amplitude de foco limitada.…”

“…A reabilitação visual ideal após uma cirurgia de catarata seria aquela que proporcionasse uma visão satisfatória para perto e para longe com independência do uso dos óculos (1)(2)(3)(4)(5)(6) . Na ausência da acomodação natural do cristalino, uma alternativa seria o implante da lente intra-ocular (LIO) multifocal (1) .…”
