Purpose.
To evaluate the effect of cap-lenticule diameter difference (CLDD) on the visual outcome and higher-order aberrations (HOAs) of small-incision lenticule extraction (SMILE).
Methods.
A total of 132 patients who had bilateral SMILE for myopia or myopic astigmatism were included.
The CLDD was 0.4 mm in 54 patients (group 1) and 1.0 mm in 78 patients (group 2).
The refractive parameters, uncorrected (UDVA) and corrected distance visual acuity (CDVA), and HOAs were determined preoperatively and during six months follow-up.
Results.
Group 1 had better CDVA (in logMAR) compared to group 2 at day 1 (−0.07 ± 0.07 versus 0.04 ± 0.07, resp.; p<0.001) and week 1 (−0.07 ± 0.07 versus –0.04 ± 0.07, resp.; p=0.001).
The visual acuity improved more in group 1 than in group 2.
The UDVA (in logMAR) was 0.07 ± 0.07 and 0.29 ± 0.09 at day 1 (p<0.001) and −0.08 ± 0.07 and −0.06 ± 0.06 at six months (p=0.038) in group 1 and group 2, respectively.
Group 1 was associated with significantly less induction of HOAs (0.24 ± 0.08 μm and 0.32 ± 0.26 μm, resp.; p=0.002).
Conclusions.
In SMILE, 0.4 mm CLDD is associated with better visual outcome and less induction of HOAs than 1.0 mm.
Narrow CLDD should be considered in SMILE to increase the visual acuity particularly in the early postoperative period.
