“…A WASCA aberrometer (Carl Zeiss Meditec AG, Jena, Germany) was used to measure ocular aberrations from the whole eye (centered with reference to the center of the pupil) [11][12][13][14]. Aberrations were measured in darkness without cycloplegics before the operation and 6 months after the operation.…”

Purpose: The aim of this study was to compare visual outcomes after small incision lenticule extraction (SMILE) and femtosecond laser-assisted in situ keratomileusis (FS-LASIK) for high myopia. Methods: In this prospective, comparative study, a total of 52 eyes of 34 consecutive highly myopic patients with spherical equivalent within the range of –8.00 to –10.00 diopters were recruited. Twenty-three eyes of 16 patients were in the FS-LASIK group and 29 eyes of 18 patients were in the SMILE group. Visual outcomes and wavefront aberrations were analyzed preoperatively and 6 months postoperatively. Results: At the postoperative 6-month visit, 96.6% in the SMILE group and 91.3% in the FS-LASIK group achieved unchanged or better corrected distance visual acuity (CDVA). As for uncorrected distance visual acuity (UDVA), 96.6% in the SMILE group and 95.7% in the FS-LASIK group achieved UDVA of 20/20 or better. As for wavefront aberrations, high-order aberrations (HOAs) and spherical aberrations increased significantly after surgery in both groups relative to corresponding preoperative values (p < 0.001), and vertical coma increased after SMILE (p < 0.001). No statistically significant differences in changes of HOAs (p =0.90), spherical aberrations (p = 0.07), horizontal coma (p = 0.56), coma (p =0.08), horizontal trefoil (p =0.19), vertical trefoil (p = 0.90), and trefoil (p = 0.45) were detected between the 2 groups, except for vertical coma (p < 0.01). Conclusions: SMILE is as effective as FS-LASIK in correcting high myopia, but attention should be paid to the induction of vertical coma in highly myopic patients following a SMILE procedure.

“…Moreover, it has the advantages of reversibility and rapid recovery. Though a low incidence of adverse events such as intraocular pressure (IOP) elevation and crystalline lens opacities was noticed (Guber et al 2016), the long-term safety, efficacy, predictability and stability of the procedure have been well demonstrated (Sanders & Vukich 2006;Igarashi et al 2009;Kamiya et al 2012;Chen et al 2019). However, subjective symptoms, such as haloes and glare, were reported early postoperatively (Shimizu et al 2012).…”

“…There is increasing concern regarding the visual outcomes of ICL and SMILE. It has been shown that objective visual outcome, in terms of contrast sensitivity and higher-order aberrations (HOAs), after ICL was superior to that after laser refractive surgery, for example laserassisted in situ keratomileusis (LASIK) and laser-assisted subepithelial keratomileusis (LASEK), for high myopia (Igarashi et al 2009;Chen et al 2019). For patients with high myopia, postoperative visual quality, based on the Optical Quality Analysis System (OQAS) II values, was reported to be slightly better after ICL than after SMILE (Qin et al 2019).…”

Purpose To investigate differences in the objective and subjective visual quality of patients with high myopia following implantable collamer lens V4c (ICL V4c) versus small incision lenticule extraction (SMILE) early postoperatively. Methods This prospective analysis included 94 eyes of 57 patients (8 males) in the ICL V4c group (mean spherical equivalent (SE), −8.07 ± 1.03 dioptres (D)) and 103 eyes of 57 patients (13 males) in the SMILE group (mean SE, −7.85 ± 0.78 D). Refractive parameters and wavefront aberrations were recorded preoperatively and 6 months postoperatively. Subjective visual quality was scored with the Quality of Vision questionnaire, and operation satisfaction was evaluated 6 months postoperatively. Results At 6 months postoperatively, the efficacy index was 1.17 ± 0.16 in the ICL and 1.09 ± 0.20 in the SMILE group; the safety index was 1.21 ± 0.18 in the ICL and 1.12 ± 0.16 in the SMILE group. A significant increase in total higher‐order aberrations (HOAs) in both the ICL and SMILE groups was observed, but to a lesser degree in ICL (p < 0.05). In the ICL group, trefoil significantly increased (p < 0.05), whereas in the SMILE group, coma, trefoil and spherical aberration significantly increased (p < 0.05). Glare, haloes and blurred vision had the highest incidences after both types of surgery, and postoperative haloes were significantly more common following ICL; 96.1% of ICL‐treated and 94.9% of SMILE‐treated patients were satisfied with their visual outcomes. Conclusion ICL V4c caused lower HOAs induction than SMILE. Despite the postoperative visual disturbances, both ICL and SMILE provided good efficacy, safety, predictability and high satisfaction in correcting high myopia.

“…This is consistent with some earlier research, including that of Zhou Xingtao et al, [18] who used the OQAS objective visual quality analysis system to compare the visu al quality of wavefront aberration-guided LASIK surgery and ICL implantation and concluded that the ICL implantation introduced no new aberrations and achieved better visual quality than the LASIK operation. In another long-term comparative observation of 3 years, Zhou Xingtao et al [19] also found that compared with traditional refractive surgery, ICL implantation offers more stable visual acuity and smaller aberrations. This study found that the MTF values of the TICL group were always slightly higher than those of the LenSx + ICL group; however, the differences were not statistically signi cant.…”

Abstract BackgroundTo evaluate the safety, efficacy, and predictability of the LenSx femtosecond laser-assisted limbal relaxing incision (LRI) for correction of high myopia with low to moderate corneal astigmatism (-0.75 to -1.50D) in implantable collamer lens implantation (ICL).MethodsThis prospective clinical control study included 56 eyes from 46 patients. They were divided into an ICL group with ICL implantation (14 patients,16 eyes); a TICL group with toric ICL implantation (17 patients, 23 eyes); and a LenSx + ICL group with a LenSx femtosecond laser-assisted LRI and an ICL implantation (15 patients, 17 eyes). The visual acuity, astigmatism correction ability and visual quality were measured before and 1, 3, and 6 months after surgery.ResultsThe postoperative visual acuity of the 3 groups were higher than the preoperative visual acuity (P < 0.01), and the improvements in the LenSx + ICL group and the TICL group were greater than those in the ICL group (P < 0.01). The LenSx + ICL and TICL groups had less residual astigmatism and higher astigmatism correction index (CI) than the ICL group (P < 0.01). There was no significant difference in the three groups of total high order aberrations (HOAs) before and after surgery (P > 0.05).ConclusionLenSx femtosecond laser-assisted LRI combined with ICL implantation can effectively correct low to moderate corneal astigmatism in high myopia. Compared with TICL implantation, it can achieve similar clinical effects in the short term.Trial registrationThis article has been retrospectively registered at the Chinese Clinical Trial Registry in 10 June 2019.

Contralateral eye comparison of the long‐term visual quality and stability between implantable collamer lens and laser refractive surgery for myopia

Abstract: Both ICL implantation and LRS are safe and effective procedures for myopia with suitable indications, but ICL implantation is more stable. Fewer induced aberrations are gained after ICL implantation.
