I report a case that describes pregnancy-associated overcorrection after myopic excimer laser photorefractive keratectomy (PRK), followed by spontaneous abortion and complete reversal of the overcorrection.
A 38-year-old woman who had a best-corrected visual acuity of 20/15 OD had a cycloplegic and manifest refraction of −5.00 diopters (D). Preoperative corneal topography was notable for a symmetric bowtie pattern despite spherical manifest and cycloplegic refractions, with simulated keratometer readings of 42.50 × 45.50 at 95°. She underwent PRK for full myopic spherical correction using an excimer laser (VISX 20/20 B, VISX, Inc, Santa Clara, Calif), with anti-island software and laser scrape technique for corneal epithelium removal. She was treated for 2 postoperative days until complete reepithelialization with a bandage contact lens and tobramycin/ dexamethasone drops, 4 times daily, and then with fluorometholone drops, 4 times daily.
