Decentration following small incision lenticule extraction (SMILE) in eyes with high myopia and its influence factors.

Purpose: The purpose is to measure the decentration after small incision lenticule extraction (SMILE) in eyes with high myopia and analyze its influence factors.

Methods: This retrospective study included 86 right eyes of 86 high myopia patients who underwent SMILE surgery in our hospital from August 2017 to December 2019. Patients were examined before the surgery and 3 months postoperatively.

Changes in effective optical zone after small-incision lenticule extraction in high myopia.

Purpose: To evaluate the four measurement approaches on the determination of effective optical zone (EOZ) using Scheimpflug tomography after small-incision lenticule extraction surgery in eyes with high myopia.

Setting: Corneal refractive surgery conducted in an eye hospital in southern China.

Design: This is a retrospective cohort study.

Biomechanical Effects of tPRK, FS-LASIK, and SMILE on the Cornea.

The objective of this study is to evaluate the corneal biomechanical response to three laser refractive surgeries. Two hundred and twenty-seven patients who submitted to transepithelial photorefractive keratectomy (tPRK), femtosecond laser-assisted keratomileusis (FS-LASIK), or small-incision lenticule extraction (SMILE) were included in this study. All cases were examined with the Corvis ST preoperatively (up to 3 months) and postoperatively at 1, 3, and 6 months, and the differences in the main device parameters were assessed.

Effectiveness of the Goldmann Applanation Tonometer, the Dynamic Contour Tonometer, the Ocular Response Analyzer and the Corvis ST in Measuring Intraocular Pressure following FS-LASIK.

: To test the performance of the four tonometers in providing IOP measurements that were free of the effects of corneal biomechanics changes caused by refractive surgery.: Four tonometers were employed to provide IOP measurements for 65 participants who accepted Femtosecond laser-assisted LASIK (FS-LASIK). The measurements included GAT-IOP by the Goldmann Applanation Tonometer, DCT-IOP by the Dynamic Contour Tonometer, Goldmann-correlated IOP (ORA-IOPg) and corneal-compensated IOP (ORA-IOPcc) by the Ocular Response Analyzer, and uncorrected IOP (CVS-IOP) and biomechanically corrected IOP (CVS-bIOP) by the Corvis ST.
