Before surgery, each patient underwent angle kappa measurement using three instruments: Pentacam, Sirius, and Keratron. Prior to corneal ablation with the excimer laser during surgery, the angle kappa was measured again using an Amaris 750S. Within-subject standard deviation, test-retest repeatability, within-subject coefficient of variation, and intraclass correlation coefficient (ICC) were calculated to assess the repeatability of the angle kappa measurements using the three instruments before surgery. A Bland-Altman plot was used to evaluate the agreement between these three instruments and the Amaris 750S to measure the angle kappa.Results: For the kappa offsets measured by Sirius, Keratron, and Pentacam, the ICC values were 0.948, 0.950, and 0.931, respectively. For the measurement of the kappa axis using the three instruments, the ICC values were 0.996, 0.997, and 0.994, respectively. The 95% limits of agreement (LoA) of kappa offset between Keratron and Amaris 750S was from -0.15 to +0.09 mm, which was the narrowest among the three instruments compared with the Amaris 750S, and the narrowest 95% LoA of kappa axial was also between the Keratron and Amaris 750S.Conclusions: The results measured before Keratron, whether kappa offset or kappa axial, were relatively consistent with those measured intraoperatively using the Amaris 750S.

The IOL diopter was measured at different apertures. The optical quality of the IOLs was evaluated using the modulation transfer function (MTF), through-focus MTF, and images of the United States Air Force Target test with different apertures and corneal SA values. The IOLs were also measured while they were decentered and tilted.Results: The smaller the aperture, the wider the through-focus MTF of all tested IOLs, and the best image quality was observed with a 3-mm aperture. The diopter of aspheric IOLs with negative SA were negatively correlated with aperture size, but the result was opposite for spherical IOLs. The IOL power difference was more than 0.50 diopters between different apertures. All aspheric IOLs had similar MTF curves with a 3-mm aperture. Aspheric IOLs had the best visual quality with the same or similar corneal SAs. Most of the tested IOLs had lower tolerances in tilt than in decentration.Conclusions: Pupil size, SA value, the degree of decentration, and tilt had different effects on the optical performance of aspheric IOLs.

The IntraLase iFS femtosecond laser (Johnson & Johnson Vision) was used for flap creation and excimer laser ablation was performed using the SCHWIND Amaris 1050RS with aspheric aberration-free ablation profile, asymmetric pupillary offset, and seven-dimensional eye tracking. Preoperative mean spherical equivalent was -5.81 ± 2.41 diopters (D) (range: -0.63 to -13.63 D).Results: At 3 months, 95.1% and 99.6% of eyes achieved uncorrected distance visual acuity of 20/20 and 20/40 or better, respectively. The mean efficacy index was 0.99 ± 0.06 and the mean safety index was 1.0 ± 0.02. For predictability, 97.7% and 99.7% of eyes were within ±0.50 and ±1.00 D of the intended correction, respectively.

The study took place from July 2021 to March 2023 at five sites across Europe and Asia. Patients meeting all inclusion criteria including myopia up to -10.00 diopters (D) and astigmatism up to 5.00 D were enrolled to undergo SMILE using the VISUMAX 800 femtosecond laser (Carl Zeiss Meditec). Patients were examined at 1 day, 1 week, and 1, 3, and 6 months after treatment.Results: During the study period, 473 eyes (237 patients) were enrolled, treated, and analyzed. The preoperative spherical equivalent was -4.49 ± 1.87 D (range -0.25 to -10.00 D). Preoperative corrected distance visual acuity (CDVA) was 20/20 or better in 98.3% of eyes. At 6 months postoperatively, uncorrected distance visual acuity was 20/20 or better in 93.2% and 20/25 or better in 98.3% of eyes.

There was a slight increase in monocular mesopic contrast sensitivity across all cycles per degree. There was one reported case of suction loss, which was not due to ocular movement. No eyes lost two or more lines of CDVA compared to baseline.Conclusions: SMILE with the VISUMAX 800 provides excellent visual and refractive outcomes for patients with myopia and myopic astigmatism.

AL was measured shorter with the Lenstar LS 900 than with the Nidek AL-Scan, and K1, K2, and K-avg were measured steeper (P < .001 for all). Although there was no proportional bias in the AL, K1, and K-avg measurements of the Lenstar LS 900 and the Nidek AL-Scan devices (P = .83, .96, and .41 respectively), there was a proportional bias in the K2 measurements (P < .001, R2 = 0.128).

The LASIK flap in the left eye was relifted and PTK of 3 µm ablation depth was performed on the back surface of the flap. Symptoms were unresolved and 16 months later the patient underwent relift of the LASIK flap in the same eye with mechanical scraping and an additional 3 µm PTK of the flap undersurface. The right eye was then similarly treated with flap undersurface mechanical scraping and 3 µm PTK.Results: The patient's rainbow glare symptoms persisted after initial LASIK flap relift and 3 µm PTK but immediately resolved after the second relift and mechanical scraping combined with 3 µm PTK polishing of left flap undersurface. Mild epithelial ingrowth occurred after the second relift of the left eye, which was managed by mechanical debridement and YAG laser epithelial lysis.
