“…Also, the induction of aberrations with ICL was shown to be minimal and showed significant improvement in aberrations postoperatively 23. Both SMILE and FS-LASIK were reported to induce significant HOAs,24,25 although SMILE was shown to induce less aberrations compared to FS-LASIK 25. Interestingly, in this series, we observed that the HOAs increased after SMILE, but they were not statistically significant at 1 year.…”

PurposeTo compare toric implantable collamer lens (T-ICL), femto-LASIK, and ReLEx SMILE for the treatment of low to moderate myopic astigmatism in terms of long-term visual and refractive outcomes and predictability of astigmatic correction.Materials and methodsThe study included 30 eyes from 30 patients between the age groups of 21 and 40 years, undergoing bilateral surgery with any of the three procedures – T-ICL, femto-LASIK, or ReLEx SMILE – for correction of myopic astigmatism within the range of −3 to −8 D spherical equivalent (SE), with a minimum astigmatism of −0.75 D. Patients were followed up at day 1, 1 month, 6 months, and 1 year.ResultsAt 1 year, the mean cylinder reduced to −0.21±0.28, −0.17±0.36, and −0.22±0.28 D in the T-ICL, femto-LASIK, and ReLEx SMILE group, respectively. The predictability of astigmatism correction was comparable, with no statistically significant difference between the 3 groups (P>0.05). A total of 97% of eyes in ReLEx SMILE achieved a uncorrected distance visual acuity of 20/20 or better, compared to T-ICL (93%) and FS-LASIK (90%). However, gain in lines of corrected distant visual acuity (CDVA) was maximum in T-ICL group (60%). Four eyes in the femto-LASIK group had loss of CDVA by one line. Three eyes required exchange due to high vault and rotation of the T-ICL, which did not affect the final outcome.ConclusionAll 3 modalities were effective for myopic astigmatism at the end of 1 year. Quality of vision and patient satisfaction with T-ICL and ReLEx SMILE were similar and better than FS-LASIK. However, slight chances of postoperative rotation and exchange exist with T-ICL, which warrant thorough preoperative planning.

“…Laser in situ keratomileusis (LASIK) and laser epithelial keratomileusis (LASEK) have become common treatments for myopia. In previous studies, the safety, efficacy, and predictability of these treatments have been assessed by the change of visual function 8,9 and ocular anterior segment. 9,10 However, the change of ocular poster segment, especially choroid has rarely been evaluated following refractory surgery.…”

Purpose To investigate early changes in choroidal thickness (CT) and the relationship with accommodation after myopic excimer laser surgery. Methods We enrolled the right eye of 70 patients with myopia and without other ophthalmic or systemic diseases who were suitable for myopic excimer laser surgery. The CT was measured at the fovea and at distances of 0.5 and 2.5 mm for the following: nasal; temporal; superior; and inferior to the fovea preoperatively and at 1 month postoperatively. Other data collected included demographic information (age, sex, and refractive error), the amplitude of accommodation (AA), intraocular pressure, axial length, corneal thickness, and surgical parameters. The data were analyzed with a paired Student's t-test, stepwise linear regression, and correlation analysis. Results The CT was significantly thicker postoperatively compared with the preoperative CT. The AA significantly decreased postoperatively. The change in the AA was the most significant factor associated with the change in the CT at the fovea. Except for 2.5 mm inferior to the fovea, the increase in the CT at other locations was positively correlated with the decrease in the AA. Conclusions The CT increased following myopic excimer laser surgery and the change was most obvious when accompanied by a decrease in the AA early after the surgery.

“…The SMILE procedure involves the use of the femtosecond laser to create an intra‐stromal lenticule that is then manually extracted through a small peripheral incision . Early reports suggest that the safety and efficacy of the procedure is similar to LASIK in comparable cohorts and indeed may offer increased benefits for some patients …”

Small incision lenticule extraction (SMILE) represents a recent addition to the refractive surgeon's range of procedures. Although there remains a number of similarities to existing techniques in terms of patient selection and treatment parameters, consideration is required to optimise patient outcomes and satisfaction. Here, we review the selection criteria, contraindications, indications and existing published safety and efficacy outcomes.

Comparison of Corneal Shape Changes and Aberrations Induced By FS-LASIK and SMILE for Myopia

Abstract: SMILE and FS-LASIK produced distinct changes in anterior corneal shape evident in different postoperative corneal curvatures and power measurements between the two groups. Postoperative HOAs were much lower after SMILE as compared to FS-LASIK.
