To examine the effect of manifest spherical equivalent error on all-distance visual acuity (VA) in eyes that received a trifocal IOL (Alcon PanOptix; TFT00) after simulating spherical equivalent error by adding various degrees of spherical lens.
Others
Nearsightedness, emmetropia and hypermetropia are simulated by adding various degrees of spherical lens. and the visual acuity (VA) which can be put in those refraction states is measured.
Exploratory
Pragmatic
Not applicable
Monocular corrected visual acuity (VA) at various distances was measured using the all-distance vision tester (KOWA AS-15) after simulation of spherical equivalent error.
1) +1.0D addition simulating -1.0D myopia
2) +0.5D addition simulating -0.5D myopia
3) 0D addition simulating emmetropia
4)-0.5D addition simulating +0.5D hyperopia
5) -1.0D addition simulating +1.0D hyperopia
Pupil diameter, corneal astigmatism, manifest spherical equivalent value

Not applicable |
Male and Female
Sixty eyes of 30 patients who underwent bilateral implantation of a trifocal IOL (Alcon PanOptix; TFNT00) were enrolled
Preoperative exclusion criteria were patients with any pathology of the cornea, macula, or optic nerve; opaque media other than cataract; history of ocular inflammation or surgery; corneal astigmatism of 1.0 D or more; marked irregular corneal astigmatism; amblyopia; and any difficulties with examinations or follow-up. Intraoperative exclusion criteria were a small pupillary diameter that required pupil expansion procedures and eventful surgery.
