Cataract Surgery

Difference Between Actual and Target Refractive Error

Difference Between Actual and Target Refractive Error for Femtosecond Laser Surgeries at Cleveland Clinic Main Campus (N = 502)

2019

With the addition of the femtosecond laser for cataract surgery, surgeons now have a greater ability to refine refractive corrections and achieve closer proximity to target. Most patients achieved a refractive outcome following femtosecond laser-assisted cataract surgery that was near the anticipated target. In this group, 100% of patients achieved a final spherical equivalent refractive error within 1 diopter of the expected result.

Intraocular lenses can permanently correct nearsightedness, farsightedness, and astigmatism, an asymmetric curvature of the focusing structures in the eye. In this group of patients who underwent cataract surgery, 75% of patients achieved a final spherical equivalent refractive error within 0.5 diopter, 97% within 1 diopter, and >99% within 2 diopters of the expected result.
