Innovative Refractive Lens Provides Patients with Excellent Vision Across All Distances

Recent research presented at the 43rd Congress of the European Society of Cataract and Refractive Surgeons highlights the promising outcomes of a new type of intraocular lens (IOL) used in cataract and vision correction surgeries. Patients who received the TECNIS PureSEE, an extended depth of field (EDF) refractive IOL, demonstrated remarkable visual acuity across all distances—near, intermediate, and far—with many achieving independence from spectacles.

The study, which involved approximately 200 patients across 17 clinical sites in Europe and Asia-Pacific, aimed to assess the effectiveness of the TECNIS PureSEE lens in preserving and improving vision post-surgery. Visual acuity was measured using logMAR charts, a standard eye test, alongside the Manifest Refraction Spherical Equivalent (MRSE) to evaluate refractive errors.

Results revealed that patients experienced excellent distance and very good intermediate vision, along with functional near vision, often without the need for glasses. Specifically, 96% of patients reported little or no need for distance glasses, 93% for intermediate distances, 62% for near tasks, and 85% overall. Satisfaction ratings were high, with over 95% of patients expressing satisfaction and more than 96% recommending the lens to others.

Professor Oliver Findl, a leading ophthalmologist, explained that the PureSEE lens offers a fully refractive solution utilizing smooth lens surfaces that focus light effectively across multiple distances. Unlike multifocal lenses that may produce halos and glare, this lens minimizes such optical side effects, providing clearer night vision.

Compared to other lenses, the EDF IOL is designed to give a broader range of vision without rings or bumps on the lens surface, which often cause visual disturbances. This makes it a preferable choice for patients seeking less dependency on glasses while avoiding unwanted side effects associated with traditional multifocal lenses.

The study underscores the advancements in ophthalmic lens technology, moving closer to the goal of providing high-quality, spectacle-free vision for patients. As Dr. Joaquín Fernández notes, these encouraging findings expand the options available for a broader patient population seeking better post-surgical visual outcomes.
