Abstract Details

Purpose:

To report the five-year results of Trans-epithelial Photorefractive Keratectomy (TPRK) in treating myopia, hyperopia and astigmatism.

Setting:

Bina Eye Hospital, Tehran, Iran

Methods:

In this retrospective cohort study, we quantitatively compared the clinical findings and assessment of optical and refractive parameters, including slit-lamp, corneal topography, Best Corrected Visual Acuity (BCVA), and Uncorrected Distance Visual Acuity (UDVA) in 86 eyes of 172 myopic, hyperopic, and astigmatic patients before and five years after trans-PRK.

Results:

The average time for post-surgery epithelial healing was 2.97ﾱ0.83 days in male and 2.94ﾱ0.87 days in female patients; Post-op pain score was 1.88ﾱ0.68 in males and 2.25ﾱ0.73 in females, respectively. Corneal haze was observed in five patients. No long term adverse effect was reported. The pre-operative UDVA was 0.84ﾱ0.32 in male and 0.87ﾱ0.34 in female patients; while the post-operative UDVA was -0.02ﾱ0.04 in male and -0.01ﾱ0.02 in female patients. There was a highly significant correlation (P-value<0.001) in all indices except UDVA, which was almost near to be significant (P-value=0.07). In this survey, the mean safety and index were nearly 1.00.

Conclusions:

TPRK is a safe and efficient therapeutic procedure to treat all type of refractive errors including myopia, hyperopia and astigmatism with no significant adverse effect. To be touchless and short recovery time are two main characteristics of this refractive surgery.
