Abstract Details

Purpose:

This study compares stability, refractive outcome and visual outcome of implantable collamer lenses (ICL) and femtolaser-assisted LASIK (fLASIK).

Setting:

In this retrospective three-center study, total of 573 subjects with mean age of 36 years, 70% females, were treated. Baseline spherical equivalent refraction error (SEQ) was selected to be -8.0 dioptria (D) or higher myopia.

Methods:

A Visian ICLs were used (Staar, USA) and the lasers were Amaris and Esiris (Schwind, Germany). Parameters are attended refractive change versus achieved refractive change and BCVA and UCVA were compared after laser. Linear mixed model was used in statistical analysis. 203 eyes of ICL (mean SEQ -11.9 D, range to -20 D) and 726 eyes of fLASIK (mean SEQ -9.1 D, range to -14 D) were compared. Follow-up visits were 1 and 6 months.

Results:

ICL was stable from 1 month to 6 months and regression of 0.24 D was found after fLASIK, p<0.05 . The attended vs achieved refractive change was equal in 1 month, p=ns and differed in 6 months, p<0.05. BCVA increased after surgery in both groups from baseline values, p<0.05. BCVA was better in fLASIK at baseline (LogMAR fLASIK -0.02 and ICL 0.05, respectively) and in both follow-ups (fLASIK -0.06 for both and ICL -0.01 and -0.02, respectively) , p<0.05 for all. UCVA was equal 1 and 6 months (within 1 ETDRS letter), p=ns.

Conclusions:

Refractive outcome of ICL is stable, whereas a small, but statistically significant regression on 0.24 D was found after fLASIK in 6 months in high myopia. Due to this regression, refractive outcome of ICL was statistically better compared to fLASIK in 6 months. BCVA increased with both surgery types from baseline and BCVA was better in fLASIK group at baseline and in follow-ups by 2-3 ETDRS letters. UCVA was equal and within 1 ETDRS letter after both operations in both follow-ups. In clinical point of view, differences were small.
