    PRK enhancement after SMILE favorable after short follow-up


    Understanding the outliers

    MRSE outcomes in the two cases with a major undercorrection were -1.75 D and -0.88 D, respectively.

    “The patient in our series who was left with the largest undercorrection had the highest refractive error before SMILE (~-10 D), and the PRK enhancement was done just 4 months after the SMILE, which may have been too soon,” Dr. Dirisamer said. “The other patient with a major undercorrection also had enhancement early, at 4.2 months after SMILE.”

    MRSE at 3 months in the two overcorrected eyes was +1.75 D and +1.38 D, respectively. In both cases, PRK was performed using the ASA profile.

    “The ASA profile is a fixed aspheric correction independent of the amount of myopia correction and leads to overcorrection in eyes with low MRSE,” Dr. Dirisamer said.

    “Before this study was done, there were no data available to guide which PRK profile might be best,” he said. “Now we know at least that the ASA profile is not recommended.”

    Two eyes developed significant haze after PRK that was treated successfully with topical corticosteroids. Dr. Dirisamer noted these eyes were not among the eyes with loss of CDVA.

    “Perhaps the rate of CDVA loss in this series will decrease with longer follow-up,” he said.

    Dr. Dirisamer receives grant support from Carl Zeiss Meditec.
