Secondary toric intraocular lens implantation for post-operative ammetropia and astigmatism after small incision cataract surgery
Abstract
We report a case of 56-year-old female who had undergone left eye small incision cataract surgery 2 months earlier with history of no visual gain uncorrected after surgery. On examination, she had a superior scleral tunnel incision with 6.5 mm optic poly methyl metha acrylate (PMMA) posterior chamber intraocular lens (IOL) in the bag. Her manifest refraction was -5.0 diopter sphere and -3.0 diopter cylinder (DC) at 180°. Her visual acuity improved from 20/200 to 20/20 after correction. The patient underwent explanation of the PMMA IOL with implantation of 23.5 D Acriol EC-T4 toric IOL through temporal clear corneal incision. Postoperatively, at 6 months, the patient had 20/20 (p) visual acuity uncorrected improving to 20/20 after correction by -0.25DC at 40°. Postoperative ammetropia and high cylindrical power can be simultaneously corrected by placement of the toric IOL.
