Purpose: To evaluate the performance of the InnovEyes Sightmap platform (Alcon Laboratories, Inc) in refractive surgery by comparing the visual acuity and higher order aberrations (HOAs) between ray-tracing-guided laser in situ keratomileusis (LASIK) and topography-guided LASIK.
Methods: This prospective study enrolled participants who underwent either ray-tracing-guided LASIK or topography-guided LASIK. Comprehensive ophthalmic evaluations were performed preoperatively, as well as at 1 day, 2 weeks, 1 month, and 3 months postoperatively.

Purpose: To evaluate the objective and subjective visual quality 3 months after femtosecond laser-assisted in situ keratomileusis (FS-LASIK) performed with Q-value-guided optimized monovision scheme (Custom-Q) for correction of myopia with or without astigmatism and compensate for age-related accommodation deficiency.
Design: Prospective before-and-after study.
Methods: Patients who had Custom-Q FS-LASIK for myopia with age-related accommodation deficiency were included in this prospective study.
Impact of Scleral Lenses on Visual Acuity and Ocular Aberrations in Corneal Ectasia: A Comprehensive Review.

Ophthalmology, Campus Bio-Medico University, 00128 Rome, Italy.
Corneal ectasias, including keratoconus (KC), pellucid marginal degeneration (PMD), and post-LASIK ectasia, poses significant visual rehabilitation challenges due to the resultant irregular astigmatism, myopia, and higher-order aberrations (HOAs). These conditions often resist traditional corrective methods, necessitating advanced optical solutions. Scleral lenses (SLs) have emerged as a primary non-surgical option for managing these complex corneal irregularities.

Background: To evaluate clinical outcomes and visual quality 3 months after mini-monovision (spherical equivalent [SE] between - 0.25 D and - 0.50 D) femtosecond laser-assisted in situ keratomileusis (FS-LASIK) for correction of high myopia in patients with presbyopia.

Purpose: To investigate differences in objective and subjective visual quality 12 months following Q value-guided (Custom-Q) femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK) versus small incision lenticule extraction (SMILE) for correction of low-to-moderate myopia and compensate for age-related accommodation deficiency.
Methods: Clinical data of 45 patients were analyzed, of whom 23 were treated with FS-LASIK and 22 with SMILE. At the 12-month follow-up, the distance, intermediate, and near visual acuities; objective and subjective refractions; Q factor; corneal higher-order aberrations (HOAs); defocus curve; contrast sensitivity; stereopsis and a subjective visual quality questionnaire were evaluated.
