FORT LAUDERDALE, Fla. — A patient who had wavefront-guided photorefractive keratectomy showed epithelial re-growth in less than 2 weeks, according to a case study presented here.
Charles E. Campbell, PhD, and colleagues studied day-to-day surface changes after PRK in two eyes of the same patient throughout the course of 1 year. They reported the results in a poster presented here at the Association for Research in Vision and Ophthalmology meeting.
The PRK was performed with the Visx CustomVue wavefront system for the Visx Star S4 excimer laser. Corneal topography measurements were taken almost daily, the researchers said, beginning on the fourth day after surgery, immediately after a bandage contact lens was removed, for 1 month and then at wider intervals to 1 year postop.
The authors noted that the bandage lens was removed on the fourth day following surgery, and by the fifth day, the epithelium had remodeled sufficiently. They added that changes in the thickness of the epithelial layer could be observed on a daily basis.
