The ability to focus on objects at close range can sometimes be suboptimal following cataract removal and intraocular lens (IOL) implantation. Several strategies exist to address this, aiming to enhance focus for tasks such as reading or using electronic devices. These strategies involve optical correction methods or, in some cases, additional surgical interventions.
The restoration of functional vision at all distances significantly improves quality of life. Historically, reliance on spectacles for near tasks was the standard expectation after cataract surgery. However, advancements in IOL technology and refractive surgical techniques now offer greater possibilities for spectacle independence and a wider range of visual acuity.
