Advances and challenges of intraocular lens design [Invited]

Abstract: Phacoemulsification technique with intraocular lens implantation has been a common treatment for cataract patients. With rising demand among the public, new technologies for lens design have emerged to minimize intraocular aberrations, improving visual quality to the largest extent. This paper systematically reviews the development of materials applied in lens manufacturing, the different categories of intraocular lenses, and respective design principles. The advantages and potential drawbacks of intraocular l… Show more

“…A diferencia de los materiales rígidos utilizados al principio (como el PMMA), los materiales blandos desarrollados posteriormente (silicona, acrílico hidrofílico y acrílico hidrofóbico) permiten enrollar la lente intraocular y realizar la inserción mediante una aguja, practicando una pequeña incisión que no requiere sutura y es menos traumática (Zeng & Fang, 2018).…”

“…Los hápticos aseguran una posición estable de la lente en el saco capsular. Aunque no forman parte de la zona óptica de la lente intraocular, su diseño es importante para minimizar el riesgo de desplazamientos axiales o laterales e inclinaciones, lo que contribuiría al incremento de aberraciones que deterioran la imagen retiniana (Zeng & Fang, 2018). En el caso de las lentes tóricas, utilizadas en los pacientes que requieren compensar su astigmatismo corneal, la estabilidad de la lente es aún más crítica.…”

“…For optimum performance and ocular health, the contact lens and intraocular lens design require specific fitting principles to be adhered to. To assist with the fitting procedure, a comprehensive understanding of the shape profiles and positions of corneal, scleral, and lens in the human eye is necessary [ 18 , 19 , 20 ].…”

“…This approach should enable clear vision in various distances without the use of spectacle or contact lenses, the so-called spectacle lens or contact lens independence. The optical design of multifocal IOL can be divided in to refractive or diffractive designs and provide foci for two distances (bifocal IOLs [BIOL]), three distances (trifocal IOLs [TIOL]) or are the so-called extended-depth-of-focus lenses, where a distinct focus is not perceivable 4,5. Since the development of any multifocal design of IOLs at a first glance is done by optical design software, the testing prior to the implantation is normally done on optical benches in order to ensure the compliance to regulatory requirements.…”
