飞秒激光小切口基质透镜取出术和飞秒激光辅助准分子原位角膜磨镶术的比较

近２０ａ来随着飞秒激光技术的飞速发展,眼科手术应用飞秒激光开展了许多新的应用。飞秒激光小切口基质透镜取出术和飞秒激光辅助准分子原位角膜磨镶术都是应用飞秒激光治疗近视和散光的安全有效的方法。但由于手术机理和手术方式不同,所以在术后角膜形态学、角膜生物力学、术后疗效和并发症等方面会产生一些差异,本文就此展开综述。     

准分子激光角膜原位磨镶术和飞秒激光小切口透镜取出术术后的泪液功能障碍

泪液功能障碍被认为主要是泪膜构成的异常导致促炎因子的产生.近期的研究表明,泪膜成分的改变导致泪液功能障碍,加速眼表上皮细胞的死亡和脱落,从而导致角膜表面的不规则、泪膜不稳定和角膜神经末梢的高度敏感化.很大一部分患者在准分子激光角膜原位磨镶术(LASIK)和飞秒激光小切口透镜取出术(SMILE)后存在泪液功能障碍.本文就LASIK和SMILE术后泪液功能障碍的临床特点、泪液功能障碍潜在的发生机制以及以机制为基础的合理治疗方案进行综述.

结论：SMILE与FS-LASIK均可有效提高近视性屈光参差患者UCVA,改善视觉质量,但SMILE术后角膜高阶像差更低、并发症发生率更小,整体效果更好。

飞秒激光小切口角膜基质透镜取出术术后并发症

飞秒激光小切口角膜基质透镜取出术(SMILE)是一种用于治疗屈光不正的无瓣飞秒激光辅助屈光手术。自2011年首次发表关于SMILE手术的研究以来,这种微创屈光手术因其无需制作角膜瓣,从而避免了相关并发症,已经迅速在眼科界受到青睐。此项创新性技术的优势包括：对角膜生物力学影响小、降低干眼风险以及减少基质层暴露。其在治疗近视和近视散光方面具有稳定性、安全性和有效性。尽管具有诸多优势,但该技术的实施仍具挑战性,并可能有各种术后并发症,如：干眼、感染性角膜炎、弥漫性板层角膜炎、暂时性光敏感综合征、角膜扩张、压力诱导层间基质角膜、角膜上皮内生、视觉相关变化等。为了获得最佳的屈光效果,应早期识别和适当的处理相关并发症。文章对SMILE术后各种并发症的危险因素、临床特点、处理及预防作一综述。     

Dry eye and corneal sensitivity after small incision lenticule extraction and femtosecond laser-assisted in situ keratomileusis: a Meta-analysis

AIM: To assess the corneal sensitivity and the incidences of dry eye after small incision lenticule extraction (SMILE) and femtosecond laser-assisted in situ keratomileusis (FS-LASIK). METHODS: The Meta-analysis was performed using RevMan 5.3. We searched on PubMed from inception to March 2016. Summary weighted mean difference (WMD) and 95% confidence intervals (CIs) were used to analyze the datum. Random-effects or fixed-effects models were chosen up to between-study heterogeneity. The main outcomes were composed of the Ocular Surface Disease Index (OSDI) scores, tear film break-up time (TBUT), Schirmer Test and corneal sensitivity. RESULTS: Eight eligible studies including 772 eyes (386 in SMILE group and 386 in FS-LASIK group) were identified. The parameters have no significiant difference heterogeneity between SMILE and FS-LASIK group preoperatively. There were significant differences between the two groups in OSDI scores at one and three months postoperatively, in TBUT at one and three months postoperatively, in corneal sensitivity at one week, about one month and three months postoperatively. However, there was no significant difference observed in Schirmer Test at the follow-up periods. CONCLUSION: Compare to FS-LASIK, dry eye and the corneal sensitivity recover better in the SMILE group, in first three months after the surgery.     

Three-year results of small incision lenticule extraction and wavefront-guided femtosecond laser-assisted laser in situ keratomileusis for correction of high myopia and myopic astigmatism

AIM: To compare and calculate the 3-year refractive results, higher-order aberrations (HOAs), contrast sensitivity (CS) and dry eye parameters after small incision lenticule extraction (SMILE) and wavefront-guided femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK) for correction of high myopia and myopic astigmatism. METHODS: In this prospective, non-randomized comparative study, 78 eyes with spherical equivalent (SE) of -8.11±1.09 diopters (D) received a SMILE surgery, and 65 eyes with SE of -8.05±1.12 D received a wavefront-guided FS-LASIK surgery with the VisuMax femtosecond laser (Carl Zeiss Meditec, Jena, Germany) for flap cutting. Visual acuity, manifest refraction, CS, HOAs, ocular surface disease index (OSDI) and tear break-up time (TBUT) were evaluated during a 3-year follow-up. RESULTS: The difference of uncorrected distance visual acuity (UDVA) postoperatively was achieved at 1mo and at 3mo, whereas the difference of the mean UDVA between two groups at 3y were not statistically significant (t=-1.59, P=0.13). The postoperative change of SE was 0.89 D in the FS-LASIK group (t=5.76, P=0.00), and 0.14 D in the SMILE group (t=0.54, P=0.59) from 1mo to 3y after surgery. At 3-year postoperatively, both HOAs and spherical aberrations in the SMILE group were obviously less than those in the FS-LASIK group (P=0.00), but the coma root mean square (RMS) was higher in the SMILE group (0.59±0.26) than in the FS-LASIK group (0.29±0.14, P=0.00). The mesopic CS values between two groups were not statistically significant at 3y postoperatively. Compared with the FS-LASIK group, lower OSDI scores and longer TBUT values were found in the SMILE group at 1mo and 3mo postoperatively. With regard to safety, no eye lost any line of CDVA in both groups at 3y after surgery. CONCLUSION: Both SMILE and wavefront-guided FS-LASIK procedures provide good visual outcomes. Both procedures are effective and safe, but SMILE surgery achieve more stable long-term refractive outcome and better control of early postoperative dry eye as compared to FS-LASIK.

结论：随着手术矫正的屈光度数增加,术后有效光学区减少越多,角膜高阶像差增加越明显; SMILE术后1 mo角膜高阶像差较术前增加。

Clinical outcomes of small incision lenticule extraction versus femtosecond laser-assisted LASIK for myopia: a Meta-analysis

AIM: To evaluate the possible differences in visual quality between small incision lenticule extraction (SMILE) and femtosecond laser in situ keratomileusis (FS-LASIK) for myopia. METHODS: A Meta-analysis was performed. Patients were from previously reported comparative studies treated with SMILE versus FS-LASIK. The PubMed, EMBASE, Cochrane, Web of Science and Chinese databases (i.e. WANFANG and CNKI) were searched in Nov. of 2016 using RevMan 5.1 version software. The differences in visual acuity, aberration and biomechanical effects within six months postoperatively were showed. Twenty-seven studies including 4223 eyes were included. RESULTS: No significant differences were observed between SMILE and FS-LASIK in terms of the proportion of eyes that lost one or more lines of corrected distance visual acuity after surgery (P=0.14), the proportion of eyes achieving an uncorrected distance visual acuity of 20/20 or better (P=0.43), the final refractive spherical equivalent (P=0.89), the refractive spherical equivalent within ±1.00 diopter of the target values (P=0.80), vertical coma (P=0.45) and horizontal coma (P=0.06). Compared with the FS-LASIK group, total higher-order aberration (P<0.001) and spherical aberration (P<0.001) were higher and the decrease in corneal hysteresis (P=0.0005) and corneal resistance factor (P=0.02) were lower in the SMILE group. CONCLUSION: SMILE and FS-LASIK are comparable in efficacy, safety and predictability for correcting myopia. However, the aberration in the SMILE group is superior to that in the FS-LASIK group, and the loss of biomechanical effects may occur less frequently after SMILE than after FS-LASIK.     

Comparative study of functional optical zone: small incision lenticule extraction versus femtosecond laser assisted excimer laser keratomileusis

AIM: To investigate the size of functional optical zone (FOZ) after small incision lenticule extraction (SMILE) versus femtosecond laser assisted excimer laser keratomileusis (FS-LASIK) for myopia correction and potential associated factors for FOZ.METHODS: A total of 133 patients who received corneal refractive surgery in our hospital between November 2018 and July 2021 were retrospectively enrolled. There were 63 patients (123 eyes) in SMILE group and 70 patients (139 eyes) in FS-LASIK group. The size of FOZ was measured using Pentacam 3-dementional anterior segment analyzer before and 3mo after surgery, so as to analyze postoperative achieved functional optical zone (AFOZ) and its contributing parameters.RESULTS: When planned functional optical zone (PFOZ) was 6.5 mm for both groups, AFOZ was 1.45±0.27 and 1.67±0.25 mm smaller than preoperative FOZ in SMILE group and FS-LASIK group 3mo after surgery. AFOZ in SMILE group was significantly larger than that in FS-LASIK group (P<0.001). Variation of FOZ was negatively correlated with preoperative spherical equivalent (SE) and positively correlated with variation of mean keratometry value (△Km), variation of spherical aberration (△SA), and variation of Q-value (△Q, all P<0.001) in both groups. Multiple variable linear regression equations were △FOZ=1.354-0.1×pre-SE+0.336×△Q+1.462×△SA in SMILE group and △FOZ=1.512+0.137×△Q+0.468×△SA in FS-LASIK group.CONCLUSION: AFOZ is significantly smaller than preoperative FOZ in both SMILE and FS-LASIK groups. With the same PFOZ, larger AFOZ is achieved in SMILE group than in FS-LASIK group.

目的：分析飞秒激光微切口角膜基质透镜取出术(small incision lenticule extraction, SMILE)术后并发症,探讨其发生的原因、处理对策及对预后的影响。

方法：回顾性分析我院2016-06/2017-05进行的SMILE患者1 127例2 236眼的临床资料,随访时间为6mo。

结果：术后并发症总体发生率为8.05%,包括弥漫性层间角膜炎74眼(3.31%)、视力恢复延迟58眼(2.59%)、角膜层间异物残留14眼(0.63%)、视物重影34眼(1.52%)。1眼存在严重偏中心切削者术后3mo视力尚未恢复,行角膜地形图引导的准分子激光上皮下角膜磨镶术(laser-assisted subepithelial keratomileusis,LASEK)。所有患者并发症经适当处理后结果良好,术后裸眼视力均达到或超过术前最佳矫正视力。

结论：尽管SMILE存在一定比例术后并发症,但手术总体是安全的。术中注意手术技巧,调整手术参数,术后合理用药可以减少并发症的发生。
