Summary: A long-term follow-up study on 11 patients with progressive keratoconus who underwent SFII surgery revealed that SFII is an effective procedure in preventing the progression of keratoconus. The minimally invasive procedure is able to maintain the biometry stability of the cornea.

Summary: For patients with high myopia, both SMILE and FS-LASIK are safe, efficacious, and predictable. However, the SMILE group showed better postoperative corrected distance visual acuity (CDVA) than the FS-LASIK group, and induced less aberration. Further comparative studies are needed to determine if SMILE can provide better visual quality than FS-LASIK in high myopia patients.

Summary: This study reported a case of bilateral corneal ectasia 3 years after small incision lenticule extraction (SMILE) surgery. The patient had normal preoperative topography in the right eye and abnormal topography in the left eye, which indicated a risk factor for developing ectasia. This case suggests that corneal ectasia can occur after SMILE surgery even with normal preoperative topography.

Summary: This study investigated and compared tear proteomic and neuromediator profiles following SMILE and LASIK procedures, revealing significant differences at different time points between the two procedures, despite ultimately converging clinical dry eye signs.

Summary: The study investigated the morphologic and histopathologic changes in allogeneic endokeratophakia using hyperopic lenticules derived from SMILE in rabbits. The results showed gradual integration of lenticules with corneal stroma and regular arrangement of corneal collagen, indicating the safety and feasibility of this approach for potential applications in corneal corrections.

Summary: The surface quality of corneal stromal lenticules ablated using a femtosecond laser during SMILE surgery was suboptimal, with the front surface being smoother than the rear surface and the edge not as regular as when cut with microscissors.

Summary: The purpose of this study was to investigate the quantitative changes in iris and retinal blood flow indices after FS-LASIK and SMILE surgeries. The results showed a short-term decrease in iris and retinal blood flow indices after surgery, but patients eventually recovered their vision. This phenomenon should be carefully considered, especially in patients prone to anterior segment lesions.

Summary: This case demonstrates that hormonal changes during pregnancy could impact the biomechanical stability of the cornea, leading to corneal ectasia after corneal refractive surgery. Surgeons should be vigilant for corneal ectasia in pregnant patients, as hormonal changes can affect corneal biomechanical stability.

Summary: This study investigates the changes in corneal densitometry (CD) after small incision lenticule extraction (SMILE) and femtosecond laser-assisted in situ keratomileusis (FS-LASIK) over the course of 7 years. The study found no significant difference in CD between the two groups preoperatively and at 3 and 7 years postoperatively. CD values in the anterior and central layers initially decreased and then increased at 7 years postoperatively, while CD values in the posterior layer consistently decreased throughout the study period.

Summary: This systematic review and meta-analysis examined whether SMILE is superior to FS-LASIK in corneal biomechanics. The analysis of ocular response analyzer and corvis ST parameters showed no statistical difference in corneal biomechanics between SMILE and FS-LASIK at 3 months post-surgery.

Summary: The study identified factors affecting posterior corneal elevation post-SMILE, with stromal bed thickness percentage being the best predictor of corneal stability.

Summary: This study reported a case of bilateral ectasia after SMILE surgery in a 23-year-old female patient, which was successfully stabilized after CXL treatment for 5 years. The study indicated that the contraindications for LASIK surgery are also applicable to SMILE surgery.

Summary: This study compared the central corneal thickness (CCT) treated with different surgical methods for myopia correction and found no significant difference in the measured CCT reduction postoperatively among small incision lenticule extraction (SMILE), femtosecond laser-assisted in situ keratomileusis (FS-LASIK), and laser-assisted subepithelial keratomileusis (LASEK). However, the predicted CCT reduction was significantly different, with SMILE being overestimated and FS-LASIK and LASEK being underestimated. This suggests that the laser platform may have some biases in predicting the CCT reduction.

Summary: This study reports the predictive factors of myopic regression in patients who had undergone small incision lenticular extraction (SMILE) and femtosecond laser-assisted laser in situ keratomileuses (FS-LASIK) after 3-12 months of follow-up. Preoperative higher-order aberration root mean square, anterior chamber depth, pre-subjective sphere, corneal diameter, optical zone, and predicted depth of ablation were found to be predictors of myopic regression.

Summary: The study compared the clinical outcomes of SMILE Xtra and SMILE procedures at a 24-month follow-up. There were no significant differences between the two procedures in terms of visual acuity, corneal curvature, and aberration.
