Myopia superimposed on presbyopia is more common, you can prepare two pairs of glasses, myopia and presbyopia, according to the need to choose, but it is more cumbersome; you can wear multifocal glasses or deduct part of refractive error when choosing the lens power for cataract ultrasonic emulsification. Since myopia and presbyopia require different types and degrees of lenses for correction of hyperopia, it is possible to design more than one degree of lenses in the same pair of spectacles to meet the needs of distance and near vision without replacing the spectacles. However, multifocal lenses are more difficult to adapt to, so gradient multifocal lenses with more complex designs are also an option. There are multiple choices of IOL lenses for cataract implantation, such as monofocal, multifocal or gradient IOLs to offset part of the refractive error, which can be used to achieve the effect of wearing normal presbyopia glasses or no glasses at all after the surgery. It is necessary to choose the appropriate correction or treatment for each patient’s different conditions, and the choice should be made in conjunction with the actual situation under the advice of a professional optometrist or doctor.
