| Title | Comparison of visual results after SMILE corneal laser vision correction and V4c implantable collamer lens surgery in the treatment of low to moderate myopia with or without astigmatism: medium to longterm results |
| Purpose | To compare safety, efficacy and refractive stability of Small Incision Lenticule Extraction (SMILE) with V4c Implantable Collamer Lens (ICL) surgery for the correction of low to moderate myopia with or without astigmatism. |
| Methods | We conducted a retrospective observational case study evaluating charts of 266 eyes undergoing ICL implantation and 414 eyes undergoing SMILE in eyes with low to moderate myopia (manifest spherical equivalent of ≤ -8 diopters) and with or without astigmatism (manifest cylindrical equivalent of ≤ -3 diopters). We extracted and compared pre- and postoperative uncorrected visual acuity (UCVA), refractive outcome and potential loss of best spectacle corrected visual acuity (BSCVA) at 1 week, 1 month and 1 year postoperative. |
| Results | In the ICL group, the mean spherical equivalent was -6,20 D ± 2,74D preoperatively and -0,09 ± 0,39 at 1m postoperative. In the SMILE group, the mean spherical equivalent was -5,43 D ± 1,65 D preoperatively and -0,05 D ± 0,59 D at 1m postoperative. The percentage of eyes within 1D attempted was 100% for ICL treated eyes and 99% for SMILE treated eyes. The percentage of eyes within 0,5 D attempted was 85% for ICL and 86% for SMILE. Both procedures have 0% loss of two lines BSCVA at 3 months postoperative. |
| Conclusion | Efficacy, safety and stability seem to be equal for both procedures. More data and longer follow up will show if the preliminary hypothesis will stand. |
| Conflict of interest | No |
