Corneal alterations due to radial keratotomy (RK) complicate intraocular lens calculations, which may explain why there have been few reports of toric (TIOL) implantation after excessive or multiple operations. A 71-year-old male with a history repeated RKs and at least 30 corneal incisions in each eye was referred for cataract surgery. Preoperatively, the best-corrected distance visual acuity 0.7 decimal (0.15 logMAR) right 0.9 (0.05 left eye. The refractive errors were -8.00 -3.00 × 80 -6.00 -3.50 80, respectively. total cylindrical powers (real power; anterior posterior) were, respectively, -0.90 D -3.60 9 a.m., compared -1.60 -3.80 1 p.m. astigmatism considered symmetric diurnally stable; therefore, an XY1AT6 TIOL (Hoya, Tokyo, Japan; power plane, +3.75 D) implanted. non-toric lens, XY1 (Hoya), implanted Six-month postoperative acuities 1.2 (-0.08 1.0 (0.00 eyes, Post-operative manifest refractions +0.00 70 -1.00 -2.00 85, reduced eye; we believe that even RKs, can be suitable candidate correct if is stable symmetric.
