The mean regression between 3-month and 5-year visits was only 0.26 D, but the difference was significant. Methods: Opening of the corneal . The minimum follow-up was 15 years. Certain heterogeneity of the research results presented in this review can be partially explained by the subjective nature of the study algorithm (in particular, the need for manual tracing of nerve fibers) and the lack of objective quantitative indicators of CNF condition suitable for statistical processing. Follow-up was 2 months, 2 years, and > 7 years postoperatively. Abott, Alcon, AlimeraSciences, Allergan, AMO, Bayer, Carl Zeiss Meditec, Ellex, Fluoron, Geuder, A finite-element anisotropic collagen fiber-dependent model of myopic surgery using patient-specific corneal geometry was constructed for LASIK, small-incision lenticule extraction, and a geometry analog model with unaltered material properties from preoperative but with postoperative geometry including thickness. Prospective case series. Deshalb hat jedes Verfahren auch Nachteile, die beachtet werden sollten. We demonstrate a steepening of the anterior corneal surface after injection of a transparent, liquid filler material into a laser-dissected intrastromal pocket. 2020;36(9):585-591.]. Stress distribution between small-incision lenticule extraction simulations and the geometry analog model were similar. The procedure was performed using the VisuMax femtosecond platform. FINANCIAL DISCLOSURE: No author has a financial or proprietary interest in any material or method mentioned. Nachteile und Risiken der ReLex SMILE sind beispielsweise, dass aktuell noch keine wellenfrontgeführte-Korrektur möglich ist und die Visuserholung langwieriger ist als nach einer LASIK. The mean regression was 0.07 D. Early visual recovery and refractive outcomes after femtosecond lenticule extraction were affected by the scanning trajectory of the laser. Preoperative spherical equivalent averaged -7.53 ± 1.18 diopters (D). Analysis of the long-term results of ReLEx® SMILE allows us to conclude: the method is safe and effective, provides high predictability of refractive results in correcting various degrees of myopia. Two eyes lost 1 line of CDVA. Two years after ReLEx® SMILE, refraction of ± 0.5 D from planned in the study groups was achieved, respectively, in 94.9, 88.2, 76.6 % of cases, ± 1.0 D in 100 % of cases in I, II groups, in 97 % of cases in III group. The corrected index (CI = |SIA|/|TIA|) varied from 1.03 ± 0.07 at 1 month to 1.06 ± 0.10 at 30 months, which was higher when correcting moderate astigmatism than when correcting high astigmatism (P = .041) at 30 months postoperatively. OSI was significantly lower after SMILE than FS-LASIK. Methods Average CCT, TCRP, and anterior Km significantly increased (P < .001), whereas the posterior Km and total corneal aberrations remained stable (P > .092). Another 30 high myopia patients (60 eyes) who had worn corrective spectacles for more than 5 years were selected as the control group. Results: Der wichtigste Vorzug beim ReLEx smile liegt darin, dass diese Methode vollständig auf einen Flap verzichtet und damit äußerst risikoarm ist. Ärzte im Ausland: Vorteile und Nachteile! Purpose: In the (ReLEx/SMILE) method a refractive lenticule is generated by the femtosecond laser, which is subsequently extracted through a small incision. Nur durch ein persönliches Beratungsgespräch inkl. The mean SE change was -0.40 D in women (P < .04) and -0.08 D in men (P = .8). All had myopic corrections with a 6.0 mm optical zone. The VisuMax femtosecond laser system was used to perform small incision lenticule extraction to treat refractive errors. Sluyterman v. L. and Russmann are employees of and Drs. Patients and Methods No significant change in trefoil was detected. Results: The results in the moderately myopic eyes were comparable. Purpose Resultados: There were significant differences in SSI (t = 8.960, p<0.01) and IR (t = − 3.509, p<0.01) between the low and high myopia groups. Die Langzeiterfahrungen und Weiterentwicklungen von ReLEx Smile sollten allerdings noch abgewartet werden. This research was approved by the ethics committee of Xiangya Hospital and the IRB approval number is 201612074. Average CCT, TCRP, and anterior Km significantly increased (P < .001), whereas the posterior Km and total corneal aberrations remained stable (P > .092). The cap was perforated in 4 eyes, and a major tear occurred in 1 eye; however, none of these patients had late visual symptoms. Nachteile des Augenlasers reLEx-SMILE Schwierigkeiten bei Nachkorrektur. Results: Post by Blinki » 07.07.2014, 21:52 Ist ja unglaublich! Dies bedeutet, dass Ihr Chirurg auch Metall in Ihre Wirbelsäule legt, um die Wirbelknochen zusammenzuhalten. The mean spherical equivalent (SE) was -4.73 +/- 1.48 (SD) preoperatively and -0.33 +/- 0.61 D 6 months postoperatively. Design The long-term visual outcome remained stable after SMILE, but with an average regression of -0.34 D over 7 years. However, it is unsuitable for the treatment of extremely high myopia because there is undercorrection and regression as existed in laser-assisted in situ keratomileusis (LASIK), and compound hyperopic astigmatism currently could not be corrected either. Conclusions: Design: Recently, it was shown that correction of low hyperopia can be achieved by implanting intracorneal inlays or allogeneic lenticules. We found equally good visual and refractive outcomes after small incision lenticule extraction for the correction of high and of moderate myopia combined with an astigmatic correction of up to 3 D, respectively. LASIK is as of now the predominant strategy in refractive surgery but SMILE also spreads rapidly between surgeons. Im Buch gefunden – Seite 247Die wichtigsten Nachteile gegenüber der LASIK sind die etwas geringeren Grade der korrigierbaren refraktiven Fehler und eine ... Refraktive Lentikelextraktion Die refraktive Lentikelextraktion (ReLEx) ist ein relativ neues Verfahren, ... With regard to changes from before to 6 months after surgery, mean reduction in subbasal nerve density was 14.22 ± 6.24 mm/mm(2) in FLEX eyes, and 9.21 ± 7.80 mm/mm(2) in SMILE eyes (p < 0.05).

Conclusion Aims To evaluate the long-term visual, refractive outcomes and vision-related quality of life after small incision lenticule extraction (SMILE) for the correction of high myopia. Small incision lenticule extraction (SMILE) is a novel 1-step refractive procedure with femtosecond laser for the correction of myopia and myopic astigmatism. Cutting precision and the required absorbed energy for flap dissection were compared for Gaussian and vortex beams on ex vivo porcine corneal specimens at pulse durations between 480 fs and 9 ps. Methods Manual compensation may be an effective approach to improve astigmatic outcomes of SMILE, especially in moderate and high astigmatism. No author has a financial or proprietary interest in any material or method mentioned. To compare the early corneal wound repair and inflammatory responses after refractive lenticule extraction (ReLEx) and LASIK. Methods: The residuum of the linear regression analysis of the predictability plot was approximately 0.4 diopter. Frage zu der ReLEx smile-Behandlung: Welche Nachteile gibt es? Setting: The study took place in Alyamama Vision Refractive Center, Baghdad, Iraq. Purpose: Small-incision lenticule extraction for the treatment of myopia and astigmatism was safe and effective, and the reported AEs had no significant impact on visual acuity. Each patient was fully assessed preoperatively including visual acuity, refraction, tear breakup time, Schirmer test, corneal sensation & Ocular Response Analyzer®. Of cases with corneal complications, 308 (71.3%) had an uncorrected distance visual acuity (UDVA) of better than 20/25 and 49 (11.3%) eyes lost two or more lines of corrected distance visual acuity (CDVA) on the first day after surgery. Thereafter, the lenticule was manually removed and the flap repositioned. Apoptosis and proliferation were evaluated with TUNEL assay and Ki-67 immunostaining, respectively. Cochet-Bonnet esthesiometry (Luneau Ophthalmologie Chartres, Cedex, France) was used to evaluate corneal sensitivity preoperatively as well as at 1 week and 1 and 3 months after surgery. prospective, non-randomised, single-centre clinical study, all patients with myopia or myopic astigmatism underwent the SMILE procedure performed by one surgeon (H.S.S.) We showed that SMILE did not induce spherical aberrations. Die Rose ist die Königin der Blumen, wunderschön anzusehen, zart und betörend im Duft. Results have suggested that SMILE has acceptable outcomes in correction for high myopia <10.0 diopters (D), and it is a feasible and effective procedure for the treatment of hyperopia. On a standardized questionnaire, all patients said they were very satisfied with the results. Corneal abrasion was the most common surgical complication, constituting 10.6% of all complications, followed by adherence of the lenticule to the cap (3.5%). At 12 months, uncorrected distance visual acuity was 20/20 or better for 98% and 99% eyes in the SMILE Xtra and FS-LASIK Xtra groups, respectively (P = 0.657). Refractive lenticule extraction (ReLEx/SMILE) is a refractive surgical method developed by the authors in stages primarily for correction of myopia and myopic astigmatism, in which a femtosecond laser is exclusively used. In a prospective 6-month study 108 eyes were treated in Erfurt and Marburg. Mit bis dato über 2 Mio. The target refraction in all cases was -0.75 diopter (D). The optical quality descended after SMILE and FS-LASIK. At 6 months, 1 eye (1.0%) did not achieve a UDVA of 20/25 as a result of stage 3 DLK, but achieved 20/20 by 1 year. Thirty patients (60 eyes) with high myopia who underwent SMILE more than 5y were selected as the SMILE group. Eighty-six per cent and 90.3% of eyes were within ±0.50 D of the attempted cylindrical correction in the HA and LA groups, respectively. Slight undercorrection of refractive cylinder requires further attention. At 1 year, wavefront-optimized Femto-LASIK produced similar refractive outcomes to ReLEx(®) flex with better, but non-significant accuracy. Results In the SMILE group, the mean preoperative SE was -7.29±0.87 D (range -6.00 to -9.125 D). This prospective observational study was conducted in Espace Nouvelle Vision, Ophthalmological Clinic, Paris, France. In conclusion, guided lenticule extraction using a low-energy femtosecond laser was a promising and easy procedure. In the SMILE group, the 3-month changes in PCA were not correlated with spherical, spherical equivalent (SE), and spherical plus cylinder measurements. Twenty-four (69%) and 33 (94%) eyes, respectively, were within ±0.50 D and ±1.0 D of target refraction. Femtosecond lenticule extraction performed well in the correction of myopia. All patients were satisfied with the postoperative results although emmetropia was not reached. Methods: A total of 1054 myopic patients were included in this study. To compare small incision lenticule extraction with prophylactic cross-linking (SMILE Xtra) and femtosecond laser-assisted in situ keratomileusis with prophylactic cross-linking (FS-LASIK Xtra) in their safety, efficacy, predictability, and stability. The laser was used to cut a refractive lenticule intrastromally to correct myopia or myopic astigmatism. Results Background: Retrospective comparative case series. Since the inception of SMILE almost 10 years ago, the procedure has been rapidly growing in popularity. Financial disclosures: A total of 1054 myopic patients were included in this study. Augen lasern: Voraussetzungen. A lenticule of intrastromal corneal tissue was cut together with 2 small incisions of 3 mm using a low-energy femtosecond laser system, FEMTO LDV Z8; 1 incision led to the posterior plane and 1 to the anterior, allowing dissection of the lenticule. There was no statistically significant change in mean peripapillary RNFL or mean GCC thickness after SMILE surgery. Conclusions. The 6-month postoperative CDVA was the same as or better than the preoperative CDVA in 95% of eyes. Die 5., vollständig überarbeitete Auflage von "Auge - Brille - Refraktion" kann und will den Schober-Kurs nicht ersetzen. The main outcome measures were the comparison of the refractive and visual outcomes and the effect on corneal higher-order aberrations between the procedures. Ansonsten sind mir keine Nachteile bekannt." Spherical measurement was related to PSA. ReLEx smile: Vorteile & Nachteile. Wenn Sie Raucher sind und eine Wirbelsäulenfusion haben, sollten Sie mit dem Rauchen aufhören. Conclusion: Alle anderen Fachzentren in München sind mit dem Einsatz von RELEX SMILE noch recht zögerlich. In addition, there is slight undercorrection.
