Abstract
Purpose :
To analyze the performance of trifocal intraocular lens implantation in myopic patients with or without astigmatism
Methods :
A retrospective study examining trifocal intraocular lens (IOL) implantation in myopic patients was performed at the Willis-Knighton Eye Institute. All surgery was performed by a single surgeon. Patients were followed on postoperative day one, one month, and three months. Refraction was performed between the first and third months. A ten-question survey, scored from 0-10, was conducted one month after surgery. Inclusion criteria for low to moderate myopia involved all patients with -1 to -5 D and an axial length < 25 mm. Inclusion criteria for high myopia involved all patients with less than -5 D and axial length > 25 mm. Exclusion criteria included high spherical aberration above .6, macular pathology, glaucoma, corneal disease, or scarring.
Results :
A total of 73 eyes were included in the study, with 27 classified as high myopia and 46 as moderate/low myopia. The axial length and sphere were 26.67 +/- 1.44 mm and -7.29 +/- 2.80 D in the high myopia group vs 24.10 +/- 1.11 mm and -2.38 +/- 1.86 D in the moderate/low myopia group, P<0.0001 and P<0.0001 respectively. Binocular uncorrected distance visual acuity (UDVA), binocular uncorrected near visual acuity (UNVA), and spherical equivalent (SE) measured after 1-month post-op revealed no difference between groups when excluding post-refractive patients, P>0.05. Binocular UDVA, UNVA, and SE were also similar across all groups when correcting astigmatism with toric trifocal IOL, P>0.05. Lens satisfaction was similar between all groups, P>0.05.
Conclusions :
Trifocal IOLs have good outcomes in visual performance and patient satisfaction in patients with high myopia and astigmatism.
