Clinical effectiveness of laser-induced increased depth of field for the simultaneous correction of hyperopia and presbyopia
Journal of Refractive Surgery Jan 15, 2021
Rahmania N, Salah I, Rampat R, et al. - In this prospective comparative study, researchers sought to assess the visual outcomes of patients with presbyopic hyperopia, contrasting the current standard of monovision treatment with a novel bilateral presbyopic LASIK (Custom-Q mode) technique. The sample consisted of patients [n = 28; mean age 56.03 ± 4.31 years] with presbyopic hyperopia undergoing a bilateral presbyopic laser in situ keratomileusis technique. Compared with contact lens monovision, the findings affirm the superiority of improved depth of focus using negative spherical aberration modulation in the non-dominant eye. They also show the efficacy of positive spherical aberration induction to enhance intermediate and near vision in the dominant eye.
