Abstract Details

Purpose:

Refractive accuracy of a novel keratometry-calculation formula for IOLpc in KC

Setting:

Laservision.gr clinical and research eye institute, Athens, Greece

Methods:

42 consecutive cases evaluated with interferometry-axial length and chamber depth, automated keratometry, topography, tomography with both Scheimpflug and anterior segment-OCT. In the IOLpc (SRK-T, Holliday, and Hoffer Q formulas) the astigmatic power and axis derived from a tgAS for a 5mm optical zone. UDVA, CDVA and refraction were evaluated up to 12 months

Results:

Hoffer Q calculated the highest power and was preferred. Mean values change: UDVA from 20/400 to 20/32, CDVA: 20/50 to 20/24, Refraction in Diopters: sphere: -4.5 to -0.5 and cylinder: 3.5 to 0.75

Conclusions:

IOLpc emmetropia approximation in KC with this novel tpAS
