[Thésaurus Mesh]Procédures de chirurgie réfractiveRésumé : SIGNIFICANCE
Psychophysical estimates of spatial and depth vision have been shown to be better after bilateral ReLEx small-incision lenticule extraction (SMILE) refractive surgery for myopia, relative to photorefractive keratectomy (PRK) and femtosecond laser-assisted in situ keratomileusis (FS-LASIK). The present study provides the optical basis for these findings using computational image quality analysis.
PURPOSE
This study aimed to compare longitudinal changes in higher-order wavefront aberrations and image quality before and after bilateral PRK, FS-LASIK, and SMILE refractive procedures for correcting myopia.
METHODS
Wavefront aberrations and image quality of both the eyes of 106 subjects (n = 40 for FS-LASIK and SMILE and n = 26 for PRK) were determined pre-operatively and at 1-week, 1-month, 3-month, and 6-month post-operative intervals using computational through-focus analysis for a 6-mm pupil diameter. Image quality was quantified in terms of its peak value and its interocular difference, residual defocus that was needed to achieve peak image quality (best focus), and the depth of focus.
RESULTS
The increase in root mean squared deviations of higher-order aberrations post-operatively was lesser after SMILE (1-month visit median [25th to 75th interquartile range], 0.34 μm (0.28 to 0.39 μm]) than after PRK (0.80 μm [0.74 to 0.87 μm]) and FS-LASIK (0.74 μm [0.59 to 0.83 μm]; P ≤ .001), all relative to pre-operative values (0.20 μm [0.15 to 0.30 μm]). The peak image quality dropped and its interocular difference increased, best focus shifted myopically by 0.5 to 0.75 D, and depth of focus widened significantly after PRK and FS-LASIK surgeries, all relative to pre-operative values (P < .001). All these changes were negligible but statistically significant in a minority of instances after SMILE surgery (P ≥ .01).
CONCLUSIONS
Although all three refractive surgeries correct myopia, the image quality and its similarity between eyes are better and closer to pre-operative values after SMILE, compared with FS-LASIK and PRK. These results can be explained from the underlying increase in higher-order wavefront aberrations experienced by the eye post-operatively.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus HELB]:Optique:vision spatialeMots-clés : corneal surgery, laser myopia surgery refractive surgical procedures vision, binocular Résumé : SIGNIFICANCE: Laser refractive surgery procedures are efficacious at correcting myopia, but they result in longterm deterioration of optical quality that affects monocular and binocular visual performance. The study shows that the optical quality of the two eyes needs to be similar to optimize binocular visual performance after surgery. PURPOSE: This study aimed to systematically analyze longitudinal changes in optical quality, high- and lowcontrast logMAR acuity and random-dot stereoacuity before and after three refractive surgery procedures for correcting myopia. METHODS: A total of 106 subjects (laser-assisted in situ keratomileusis, 40; photorefractive keratectomy, 26; small-incision lenticule extraction, 40) with myopia and astigmatism ≤1.5 D participated in this prospective cohort-based study. All aforementioned outcome variables were measured in both eyes pre-operatively and 1 week and 1, 3, and 6 months post-operatively. RESULTS: Pre-operative myopic spherical equivalent of refraction (median [25th to 75th interquartile range], −6.4 D [−8.0 to −4.2 D] for laser-assisted in situ keratomileusis, −4.3 D [−5.0 to −3.5 D] for photorefractive keratectomy, −5.5 D [−6.5 to −4.3 D] for small-incision lenticule extraction) was corrected to within ±0.75 D of emmetropia in all cohorts up to 6 months post-operatively (P < .001). Higher-order wavefront aberrations, uncorrected high- and low-contrast logMAR acuity, and stereoacuity all worsened and remained so up to 6 months postoperatively, relative to pre-operative values (P < .001). Stereoacuity worsened with both interocular average and difference in the magnitude of higher-order aberrations, whereas logMAR acuities worsened only with interocular average of these aberrations (r 2 ≥ 0.40; P < .01 for all). CONCLUSIONS: Although the refractive surgery procedures tested here correct myopia, they result in a sustained (up to 6 months) loss of optical quality and spatial and depth-related visual functions post-operatively. Both interocular average and difference in the eye's optical quality seem to impair binocular visual functions after refractive surgery for myopia. Note de contenu :

[Thésaurus Mesh]Recherche qualitativeRésumé : SIGNIFICANCE: Myopia is a major health issue in East Asian countries, especially in China. By identifying Chinese patients' motivations for laser in situ keratomileusis (LASIK) surgery, our results are expected to help clinicians counsel patients before LASIK surgery and to maximize patients' post-operative LASIK surgery satisfaction, improving the quality of LASIK surgery services. PURPOSE: Laser in situ keratomileusis has become a popular type of refractive surgery for the correction of myopia worldwide. This study uses qualitative inquiry approaches to understand the motives and processes of patients' LASIK surgery decision making. METHODS: A purposive sample of 45 patients who had decided to undergo LASIK was recruited. Our qualitative study used in-depth interviews and used content analysis to interpret the data. RESULTS: Among 45 participants, 48.9% reported that career requirements were the most important reason for seeking LASIK surgery. The inconvenience of wearing glasses or lenses during activities of daily life was also a primary motive. Improving facial appearance was a main reason for female but not male respondents. Potential complications of spectacles and contact lenses in addition to maturation of LASIK technology were also reported motives to seek surgery. Participants gave multiple, overlapping reasons for LASIK surgery. CONCLUSIONS: These findings suggest that motives to seek LASIK surgery are not only a desire to correct refractive error but also social factors and confidence in improved surgical technology. The implications for clinicians are to be aware of these multiple motives for LASIK to improve the quality and effectiveness of health services for myopia patients.
