Changes in the effective optical zone following hyperopic keratorefractive lenticule extraction.
Ann Med
December 2025
Eye Institute and Department of Ophthalmology, Eye & ENT Hospital, Fudan University, Shanghai, China.
Objective: To evaluate the longitudinal changes in the effective optical zone (EOZ) following hyperopic keratorefractive lenticule extraction (KLEx) and investigate factors influencing the EOZ.
Patients And Methods: This retrospective study included 27 patients who underwent hyperopic KLEx. According to the transition zone (TZ) sizes, they were divided into two groups: group A (21 eyes) with a 2.

Department of Ophthalmology, Isfahan Eye Research Center, Isfahan University of Medical Sciences, Isfahan, Iran.
To analyze patients' quality of life (QOL) after laser vision correction (LVC) from a worldwide literature review. Studies of prospective or cross-sectional design which evaluated QOL in patients after LVC and compared that to preoperative values or a matched group of emmetropes were included. The Web of Science, PubMed, Scopus, and ProQuest were searched for relevant articles published until February 2024.

Department of Ophthalmology, University Hospital of Udine, 33100 Udine, Italy.
Refractive surgery, which includes techniques such as Laser-Assisted In Situ Keratomileusis (LASIK), Photorefractive Keratectomy (PRK) and Small Incision Lenticule Extraction (SMILE), has revolutionized ophthalmology by offering advanced solutions for vision correction. However, the choice of the technique to be used in the individual patient is highly dependent on a thorough preoperative evaluation. This retrospective study aims to investigate how preoperative parameters, including corneal thickness, topography, and refraction, affect long-term post-operative clinical outcomes.

Xinqiao Hospital, Army Medical University, 183th, Xinqiao Street, Shapingba District, Chongqing, China.
The purpose of this study was to evaluate the stability of small-incision lenticule extraction (SMILE) and laser in situ keratomileusis (LASIK) when ascending from near sea level to an altitude of 3874 m. The visual acuity (VA), intraocular pressure (IOP), spherical equivalent refraction (SER) and biometric parameters of 20 normal subjects (40 eyes, controls) and 36 subjects who underwent corneal refractive surgery (35 eyes with SMILE and 36 eyes with LASIK) were examined in Chongqing (C, 500 m above sea level) and 7-10 days after a collective travel to Shigatse (S, 3874 m above sea level). SER and corneal thickness (CT) were choosed as main indicators of the stability of corneal refractive surgery at high altitude.
