Methods: This retrospective observational cohort study included 1160 eyes of 713 patients (mean age: 72.5 \u00b1 8.3 years) who underwent phacoemulsification, intraocular lens insertion, and an evaluation of accommodative microfluctuations with an autorefractometer. Patients with posterior segment disorders resulting in visual acuity impairment and those with unavailable medical information were excluded. High-frequency components (HFCs), between 1.0\u20132.3 Hz, based on fast Fourier transform analysis of the accommodative microfluctuation data were examined at postoperative 2\u20133 (2 M) and 6 months (6 M). The relationships between the HFCs and patient age, manifest refraction, and axial length were analyzed. Results: Increased HFC values (&gt;65) were observed at a constant rate after cataract surgery, with prevalence rates of 33.4% at 2 M and 34.7% at 6 M. Postoperatively, at 2 M, increased HFC values were significantly more common for eyes with axial length \u226526 mm than for those with axial length &lt;26 mm (p = 0.0056). However, they were not significantly correlated to age or postoperative manifest refraction. Conclusions: At 2 M postoperatively, increased HFC values presented more frequently in eyes with a greater axial length; hence, the precise detection and understanding of postoperative accommodative spasms in high myopia patients is important.<\/jats:p>","DOI":"10.3390\/jcm12155135","type":"journal-article","created":{"date-parts":[[2023,8,5]],"date-time":"2023-08-05T10:25:36Z","timestamp":1691231136000},"page":"5135","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Prevalence of Accommodative Microfluctuations in Eyes after Cataract Surgery"],"prefix":"10.3390","volume":"12","author":[{"given":"Tomoko","family":"Kaida","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Miyata Eye Hospital, Miyazaki 885-0051, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takashi","family":"Ono","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Miyata Eye Hospital, Miyazaki 885-0051, Japan"},{"name":"Department of Ophthalmology, Graduate School of Medicine, University of Tokyo, Tokyo 113-8654, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tadatoshi","family":"Tokunaga","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Miyata Eye Hospital, Miyazaki 885-0051, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keita","family":"Takada","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Miyata Eye Hospital, Miyazaki 885-0051, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shota","family":"Tokuda","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Miyata Eye Hospital, Miyazaki 885-0051, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naoto","family":"Kuwabara","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Miyata Eye Hospital, Miyazaki 885-0051, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takushi","family":"Kawamorita","sequence":"additional","affiliation":[{"name":"Department of Orthoptics and Visual Science, Kitasato University School of Allied Health Sciences, Sagamihara 252-0373, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazutaka","family":"Kamiya","sequence":"additional","affiliation":[{"name":"Department of Orthoptics and Visual Science, Kitasato University School of Allied Health Sciences, Sagamihara 252-0373, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3719-0376","authenticated-orcid":false,"given":"Nobuyuki","family":"Shoji","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, School of Medicine, Kitasato University, Sagamihara 252-0374, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazunori","family":"Miyata","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Miyata Eye Hospital, Miyazaki 885-0051, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"253","DOI":"10.1016\/j.survophthal.2005.02.008","article-title":"Computer vision syndrome: A review","volume":"50","author":"Blehm","year":"2005","journal-title":"Surv.
