PURPOSE: To analyze the performance of trifocal intraocular lens (IOL) implantation in patients with high myopia vs patients with low-to-moderate myopia, with or without astigmatism. METHODS: A retrospective study examining trifocal IOL implantation in myopic patients was conducted at a single institution by one surgeon. Patients were followed on postoperative day 1, at one month, and at three months. Refraction was performed between the first and third months. A previously validated 10-question survey, scored from 0-10, was conducted one month after surgery. Patients were grouped into high myopia (≤ -5.00 diopters (D), axial length >25 mm) and low-to-moderate myopia (-1.00 to -5.00 D, axial length 90% of high (n=46) and low-to-moderate myopes (n=26). Comparing patients with >1.0 D of astigmatism in both high myopic (n=14) and low-to-moderate myopic groups (n=24) revealed no significant difference in sphere, cylinder, SE, monocular and binocular UDVA or UNVA, p>0.05. Overall patient satisfaction and the presence and severity of dysphotopsias were also similar between all groups, p>0.05. CONCLUSION: Trifocal IOL may demonstrate high levels of visual performance and patient satisfaction in the presence of high axial myopia vs low-to-moderate myopia in patients with greater or less than 1.0 D of astigmatism in specific patients.
