Design and Performance Evaluation of an Enhanced Monofocal Intraocular Lens

Enhanced monofocal intraocular lenses (IOLs), aimed at improving intermediate vision while maintaining distance vision comparable to traditional monofocal IOLs, are emerging as a promising option for cataract surgery. This study introduces a method for designing such enhanced monofocal IOL and conducts a thorough investigation of its optical performance. Additionally, the visual acuity (VA) of the pseudophakic eye implanted with the designed IOL is examined. The designed IOL provides image quality for distance vision comparable to that of monofocal IOLs and a depth of focus of 1.30 D, demonstrating its ability to improve intermediate vision. Moreover, the optical performance of the designed IOL based on this method can be comparable to commercial products, in terms of the modulation transfer function (MTF). The designed enhanced monofocal IOL demonstrates a potential for real application in cataract surgery.
