ABSTRACT
Las lentes intraoculares fáquicas (LIOf) son la opción de primera elección en la corrección de ametropías elevadas y en los casos en los que la superficie ocular o la córnea no son idóneas para realizar técnicas queratorrefractivas. Esta revisión pretende actualizar y detallar el estado actual de los seis modelos de LIOf disponibles en Europa, precisar la ampliación de sus indicaciones y describir las innovaciones de diseño que se han dado en los últimos años. Estas han consistido en las LIOf de cámara posterior, en habilitar un micropuerto central para mejorar la circulación del humor acuoso, y en disponer de mayores diámetros de zona óptica, así como de ópticas multifocales para compensar la presbicia. Se constatan los excelentes resultados de seguridad y eficacia que se obtienen, recordando la importancia de la educación de los pacientes para asegurarlas a medio-largo plazo. Finalmente revisamos las indicaciones especiales de LIOf, así como la bilensectomía, procedimiento que eventualmente requerirán una mayoría de pacientes con LIOf a medida que desarrollen cataratas por la edad
Phakic intraocular lenses (pIOL) are recommended when counselling refractive surgery candidates presenting with high ametropia or ocular surface and/or corneal conditions that contraindicate corneal refractive surgery. This review aims to present the state-of-the-art regarding pIOL models currently available in Europe, addressing their newer indications and recent design innovations. These include, in the case of posterior chamber pIOLs, the addition of a central hole to improve aqueous humour circulation, the availability of larger optical zones, and multifocal optics for the compensation of presbyopia. The review also highlights their good safety and efficacy results, as well as the role of patient education to ensure adequate outcomes in the medium-long term. The indications of pIOLs in special situations, as well as bi-lensectomy, a procedure that most pIOL patients may eventually require as they age and develop cataracts, are also addressed
