Refractive result after clear lens extraction in posterior microphthalmos with high hyperopia.

A man in his early 20s was referred for refractive surgery evaluation. 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.
