A post-operative manifest refractive error as close as possible to target is key when performing cataract surgery with intraocular lens (IOL) implantation, given that residual astigmatism and refractive errors negatively impact patients’ vision and satisfaction., Refractive errors after cataract surgery occur when the eye’s focusing power doesn’t align perfectly with the new intraocular lens (IOL), resulting in less-than-ideal vision. These errors can manifest as myopia (short-sightedness), hyperopia (long-sightedness), or astigmatism. How do you fix refractive error after cataract surgery?, In addition to a hyperopic refractive error, the ideal patient for a piggyback IOL has a stable PCIOL that is completely within an intact capsular bag, a normal or deep anterior chamber, a normal corneal endothelium, and no evidence of pigment dispersion syndrome., Refractive errors are extremely common eye conditions that make your vision blurry. Usually, all you’ll need is a new pair of glasses or contacts to restore your vision. Talk to your eye care specialist about vision correction surgery if you have a refractive error but don’t want to wear corrective lenses. What are refractive errors?, SMILE is a reliable method for treating residual refraction after cataract surgery, as it provides results in the shortest time without complications and increases patient satisfaction. The protocol was registered on clinicaltrials.gov (NCT04693663). Keywords: IOL, Pseudophakia, Refractive error, SMILE surgery, Trifocal, VisuMax., Residual refractive error refers to the remaining refractive error in the eye after a person has undergone refractive surgery, such as LASIK or PRK. It means that the eye still requires some degree of corrective lenses, such as glasses or contact lenses, to achieve clear vision..
