Results

ESD-CLs, PB-CL, and no-CL provided better CDVA than spherical CL (p<0.05).
Astigmatism was significantly less with PB-CL and ESD-CLs compared with spherical
CL and no CL (p<0.05). Coma was significantly less with ESD-CLs than PB-CL
(p<0.05); total HOAs did not differ among the four conditions. The subjective ratings for
blurred and double vision were significantly lower with ESD-CLs than with spherical CL
(p<0.05).

Baseline Characteristics

Experienced SCLwearers aged 20 to 39 years were eligible to participate in this study if they met the following criteria, wearing SCLs for more than 8 hours per day and more than five days per week, no ocular pathology or systemic disorders, and not receiving any drugs with known effects on visual acuity or accommodation.

Participant flow

After the lens had settled on the eye for at least 10 min after insertion, the assessments were conducted in the following order: (1) CDVA measurement, (2) subjective vision quality assessment, (3) aberrometry, and (4) CL fitting examination and axis misalignment of toric CL using a slit lamp. The same measurement procedure was repeated for all three CLs.

Adverse events

None

Outcome measures

1 CDVA measurement,
