摘要：

We report a case of Intacs(R) (KeraVision) implantation for the correction of pellucid marginal degeneration (PMD). Preoperatively, the patient's uncorrected visual acuity (UCVA) was 0.05, the best spectacle-corrected visual acuity (BSCVA) was 0.1, and the refraction was -2.00 -7.00 x 90 in the right eye. The flattest meridian (K1) measured 43.8@104 and the steepest meridian (K2), 51.3@14. Ultrasound pachymetry revealed a thin cornea of 420 mum. One month postoperatively, the UCVA was 0.2, the BSCVA was 0.5, and the refraction was -8.00 -7.00 x 50. Contact lens best corrected visual acuity was 0.9; 6 months postoperatively, it improved to 1.0. The use of Intacs to treat PMD seems to be viable and improves visual acuity. The residual error can be corrected with contact lenses. (C) 2003 ASCRS and ESCRS.
