**Core Concept**
Cataract surgery involves removing the cloudy lens and replacing it with an artificial lens. Post-operative glasses are prescribed to correct any residual refractive errors, such as astigmatism, presbyopia, or anisometropia, which may affect the patient's vision.

**Why the Correct Answer is Right**
The type and power of the intraocular lens (IOL) implanted during cataract surgery can influence the need for post-operative glasses. For example, if the IOL is not perfectly spherical, it may cause astigmatism, requiring glasses with cylindrical lenses to correct the refractive error. Additionally, patients may experience presbyopia, a natural age-related decline in near vision, which can be addressed with reading glasses or multifocal IOLs. The correct prescription for post-operative glasses depends on the patient's pre-operative refraction, the type of IOL implanted, and the surgeon's preferences.

**Clinical Pearl / High-Yield Fact**
When prescribing post-operative glasses, it's essential to consider the patient's pre-operative refraction, the type of IOL implanted, and the surgeon's preferences. A thorough examination of the patient's visual acuity, refraction, and ocular motility can help determine the optimal prescription for glasses.
