Visual and patient-reported outcomes of a diffractive trifocal intraocular lens in highly myopic eyes: a prospective multicenter study

Table 2 Visual acuities and prediction errors among the three groups after trifocal intraocular lens implantation

	Control group (n = 273)	High myopia group (n = 105)	Extreme myopia group (n = 78)	P value
UNVA (logMAR)	0.13 ± 0.13	0.11 ± 0.13	0.15 ± 0.13	0.214
UIVA (logMAR)	0.12 ± 0.12	0.12 ± 0.11	0.13 ± 0.10	0.590
UDVA (logMAR)	0.05 ± 0.11	0.06 ± 0.11	0.10 ± 0.14	0.005^a
CDVA (logMAR)	0.02 ± 0.10	0.03 ± 0.10	0.08 ± 0.13	< 0.001^b
SE (D)	− 0.18 ± 0.42	− 0.22 ± 0.44	− 0.19 ± 0.57	0.811
Prediction error (D)	− 0.09 ± 0.36	− 0.09 ± 0.33	− 0.13 ± 0.46	0.699

UNVA = uncorrected near visual acuity; logMAR = logarithm of the minimal angle of resolution; UIVA = uncorrected intermediate visual acuity; UDVA = uncorrected distance visual acuity; CDVA = corrected distance visual acuity; D = diopter; SE = spherical equivalent
^aSignificant difference between control and extreme myopia groups
^bSignificant difference between extreme myopia group and the other two groups
P values less than 0.05 are considered statistically significant
