Participant Flow

40 adult subjects were recruited from among patients seen at the ORASIS eye clinics, including 20 people with cataract in at least one eye and 20 subjects without cataract. The subjects included 5 people with prior refractive surgery, 5 people with high myopia, 5 people with high hyperopia, and 3 persons with dilated pupils.

PRIMARY outcome

Timeframe: 3 months

Population: The measurement of Central Corneal Thickness (CCT) and Lens Thickness (LT) is not possible with the IOLM: the IOLM cannot measure these two parameters and does therefore not display results for CCT and LT. As a consequence, the comparison in CCT and LT is only possible between the G6 and the LS, but not with respect to the IOLM.

Assessed parameters: Axial Length (AL; G6, IOLM, LS) Central Corneal Thickness (CCT; G6, LS)) Anterior Chamber Depth (ACD; G6, IOLM, LS) Lens Thickness (LT; G6, LS) Corneal Curvature (SimK; G6, IOLM, LS) White-to-White (WtW; G6, IOL, LS)

SECONDARY outcome

Timeframe: 3 months

Population: The IOLM does not measure CCT and LT. Thus, repeatability results are available with the G6 and the LS, but not with the IOLM. The IOL Master displays one average value only for WtW, which does not permit the calculation of repeatability under the present study design.

Assessed parameters: Axial Length (AL) Central Corneal Thickness (CCT) Anterior Chamber Depth (ACD) Lens Thickness (LT) Corneal Curvature (SimK) White-to-White (WtW)
