His best corrected distance visual acuity was 20\/60 in both eyes. Preoperative manifest refraction was +13.00 sphere with a 0.75 cylinder in both eyes. Posterior segment examination revealed bilateral pseudopapilloedema with a papillomacular retinal fold and a chorioretinal fold. Numerous formulas for intraocular lens (IOL) power were calculated. Bilateral clear lens extraction was performed, resulting in residual spherical equivalents of +4.50 in the right eye and +3.375 in the left eye. There was no accurate IOL power formula for posterior microphthalmos with extremely high hyperopia; however, the Hoffer Q formula may yield the least error in IOL power.<\/jats:p>","DOI":"10.1136\/bcr-2024-262893","type":"journal-article","created":{"date-parts":[[2024,12,10]],"date-time":"2024-12-10T19:10:54Z","timestamp":1733857854000},"page":"e262893","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Refractive
