Distance-Only PRK for Myopia With Astigmatism

Distance-Only PRK for Myopia With Astigmatism < 3 D (N = 113)

ᶜResults reflect both 20/15 and 20/16

Following PRK to treat all levels of myopia, 85% of eyes treated with Contoura & WFO achieved uncorrected visual acuity (UCVA) of 20/20 or better, and 89% achieved 20/25 or better. An exceptional visual result of 20/16 or better was achieved in 57%, and 23% achieved UCVA of 20/12 or better. Compared with LASIK, visual acuity measurements obtained at 3 months (as they were above) tend to underestimate final outcomes in PRK patients who often see continued improvement between 3 and 6 months.
