One‐Year Outcomes of Topography‐Guided LASIK for Myopia and Astigmatism

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Introduction To assess the efficacy and safety of topography‐guided LASIK (TG‐LASIK) in correcting myopia and astigmatism and to evaluate clinical outcomes and visual quality postoperatively. Methods We conducted a prospective study including patients aged 18–40 years with stable refraction for over 12 months.

Estimation of final cylindrical spectacle correction by Pentacam

Function and Disability Journal, 2020
Background and Objectives: Keratoconus is a non-inflammatory asymmetric corneal degenerative disease characterized by the steepening and distortion of the cornea. In this disease, irregular astigmatism makes the subjective refraction difficult. Using the

Differences between estimated postoperative corneal power (K) from 3-mm Orbscan IIz and Pentacam.

, 2015
aEstimated corneal power derived from 3.0 mm TOP was used as a reference.ΔKOrb 3 = KOrbscan IIz at 3-mm—KPentacam, CI = confidence interval, LoA = limits of agreement, TOP = total optical power from Orbscan IIz, EKR = equivalent keratometric readings ...

Visual Outcomes and Patient Satisfaction After Implantation of Enhanced Versus Standard Monofocal Intraocular Lenses With a Myopic Target Refraction: A Retrospective Comparative Study

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Purpose To compare the clinical outcomes of enhanced monofocal IOL (Eyhance) and monofocal IOL (TECNIS) implantation in cataract patients whose target refraction is myopia. Methods This is a retrospective chart review for patients who underwent cataract surgery and whose target refraction is myopia (−3 D).
