Implantation of a toric poly(methyl methacrylate) intraocular lens to correct high astigmatism

A 57-year-old man experienced a decrease in visual function because of cata ract formation. Corneal astigmatism was 13.4 diopters (D) because he had ha d a penetrating keratoplasty 27 years before. Cataract surgery was planned, and biometric data for toric intraocular lens (IOL) implantation were coll ected for the manufacture of a custom IOL. After phacoemulsification, a tor ic poly(methyl methacrylate) (PMMA) IOL of +19.0 D spherical and +12.0 D cy lindrical power was implanted via a sclerocorneal tunnel incision. Three mo nths, postoperatively, corneal astigmatism was 14.3 D and best corrected vi sual acuity (BVA), 20/25. Postoperative refraction (+1.5 -3.0 x 90) and BCV A remained stable for 7 months. No significant IOL rotation was observed Im plantation of a toric PMMA IOL corrected high corneal astigmatism. Toric IO L technology with high cylindrical power allows enhancement of IOL surgery.
