Keratopathy and pachymetric changes after photorefractive keratectomy and vitrectomy with silicone oil injection.

We present a man who, after bilateral excimer laser photorefractive keratectomy (PRK) for high myopia in the right eye, had repeated retinal detachment surgery with lensectomy and injection of silicone oil. Visual acuity fluctuated in accordance with significant central corneal thickness diurnal variation. The case illustrates the possibility of PRK as a predisposing factor for keratopathy after retinal detachment surgery with silicone injection in an aphakic eye.
