To report a case with a problem of refractive predictability after implantation of Artisan phakic intraocular lens following Intacs in a patient with keratoconus.
Nune Eye Hospital, Daegu, South Korea
A 28-year-old man with keratoconus who had undergone implantation of Intacs ring before 1 yr, underwent implantation of Artisan phakic intraocular lens on his left eye. In the left eye, preoperative uncorrected visual acuity (UCVA) was 0.02 and the best corrected visual acuity (BCVA) was 0.8 with -4.00 -2.00 80.
The UCVA at 1st postoperative day was 0.9 and the best BCVA was 1.0 with plano -0.75 170. But after 1 week, the UCVA decreased to 0.3 and the BCVA was 1.0 with -2.00 -1.00 165. After 3 months, the manifest refraction was changed slightly as -2.12 -0.50 165.
Sequential Intacs and a Artisan phakic IOL implantation was safe, stable, and effective in selected cases of keratoconus. But there is a possibility of sudden changes of the refractive errors at any postoperative period.
