Patient Population
Forty-six eyes (21 men and 25 women) of 33 patients who underwent implantation of the PCP ICL, and 47 eyes (25 men and 22 women) of 29 patients who underwent WFG-LASIK for the correction of high myopia (manifest spherical equivalent, ≤ −6 diopters [D]), were included in this observational study. The mean patient ages ± standard deviation at the time of surgery were 35.0 ± 10.3 years (range, 18 to 59 years) in the ICL group and 36.3 ± 8.7 years (range, 21 to 56 years) in the WFG-LASIK group. The
Patient Population
Preoperative patient demographics are summarized in the Table 1. There were no significant differences between the 2 groups in terms of age (P = .40, Mann–Whitney U test), gender (P = .47), logMAR BSCVA (P = .12), HOAs (P = .06 for coma-like aberrations, P = .45 for spherical-like aberrations, and P = .13 for total HOAs for a 4-mm pupil; P = .59 for coma-like aberrations, P = .99 for spherical-like aberrations, and P = .91 for total HOAs for a 6-mm pupil), or AULCSF (P = .14). However, the
Discussion
In the current study, we demonstrated that ICL implantation induced significantly fewer ocular HOAs than did WFG-LASIK in the treatment of high myopia. Moreover, we also demonstrated that ICL implantation increases CS significantly, but that WFG-LASIK significantly decreases it. Sanders and Vukich reported that the ICL had advantages over LASIK in eyes with moderate to high myopia as well as those with low myopia.12, 13 Recently, Sanders also demonstrated that ICL was superior to LASIK for

Agreement between optical coherence and Scheimpflug tomography: Vault measurements and reproducibility after implantable collamer lens implantation
2021, Journal Francais d'OphtalmologieCitation Excerpt :The phakic implantable collamer lens® (STAAR Surgical Company) is one of several options for correcting myopia, hyperopia, and astigmatism, especially when keratorefractive surgery is not indicated due to thin cornea, suspected ectasia, or high ametropia. The ICL provides rapid visual recovery and excellent optical quality with minimal adverse effects [1–3]. The ICL was designed for implantation in the posterior chamber, which is crucial to obtain the necessary safety distance between the posterior ICL surface and the anterior crystalline lens (vault) [4].
