Recambio de cristalino con lente intraocular trifocal tras queratotomía radial

To report a case with a history of previous radial keratotomy who underwent refractive lens exchange with trifocal intraocular lenses.

Case report.

A 69-year-old man underwent bilateral RK to correct myopia in both eyes elsewhere 40 years ago. He was admitted to our hospital due to progressive deterioration of vision. The uncorrected distance visual acuity in both eyes was 20/40, and the uncorrected near visual acuity (40 cm) was J10. On slit-lamp examination, mild cataract and four radial keratotomy incisions were found. The patient underwent bilateral refractive lens exchange with trifocal intraocular lenses one-week interval. We were unable to obtain the preoperative data or details of the patient's prior surgeries. Calculations were run with the American Society of Cataract and Refractive Surgery calculator using the Barret True K formula. Postoperative follow-up was continued for approximately six months. No perioperative complications were noted.

Six months after the surgery, the refractive outcomes for both eyes had stabilized, and no other complications had occurred. The patient was satisfied with the result.
