Patients who have had LASIK or other refractive surgery in the past often deeply value their glasses-free vision. So when cataract surgery is needed, the question arises: should you choose a premium lens (like a multifocal or extended depth-of-focus IOL) to minimize dependence on glasses again, or stick to a monofocal lens (single-focus) which might offer sharper quality but likely require reading glasses? The decision is nuanced. Premium lenses can provide a range of vision (distance, intermediate, near), but they split light into multiple focal points. In eyes that have had LASIK, especially for high prescriptions, the cornea already has some imperfections (spherical aberration, slight irregularities). Multifocal IOLs are “picky” about optical quality – they demand a fairly pristine corneal shape to give crisp results. Introducing a multifocal to a post-LASIK eye that has residual aberrations can sometimes exacerbate issues like halos or loss of contrast. On the other hand, many post-LASIK patients can do very well with premium lenses if they are carefully selected. Factors favoring success include: prior correction was mild to moderate (e.g., under ~5 diopters of LASIK) , corneal shape is still regular and centered, and the patient had an excellent quality of vision after their LASIK. In fact, with modern IOL designs and diagnostics, surgeons are debunking the myth that “you can’t use multifocals in post-LASIK eyes” – with the right approach, many can achieve great outcomes. However, surgeon caution is higher in cases of RK or very high correction LASIK, or early-generation LASIK with irregularities like a decentered ablation. Often, the safe play is a monofocal lens targeted for one distance (usually far), possibly combined with monovision (one eye left a bit near-sighted for reading). Monofocals tend to provide the sharpest, most contrast-rich image because all light is focused in one spot. A patient who had crisp vision with LASIK and just needs reading glasses now might be perfectly happy doing monofocal implants and using readers – essentially trading one pair of glasses (for distance, pre-LASIK) for another (for near, post-cataract). Meanwhile, a patient absolutely determined to remain glasses-independent has to accept some compromises if choosing multifocals: maybe a bit more halo at night, or the chance of needing a touch-up LASIK after cataract to fine-tune the outcome.
