Abstract Details

Purpose:

To evaluate the efficacy of topography-guided trans-PRK in a group of patients with irregular refractive errors and irregular corneas after radial keratotomy.

Setting:

Studio Oculistico, Dr. Salvatore Giugno, Viale Mario Gori 63, 93015 Niscemi (CL) Italy

Methods:

Twenty-two eyes of 20 patients who had irregular astigmatism and corneal aberrations were recruited. All eyes had excimer laser topography-guided single-step transepithelial PRK. The efficacy, safety, predictability and corneal wavefront aberration changes were assessed 8 months after the surgery.

Results:

The patients age ranged from 43 to 69 years, there were 14 men and 6 women. At 6 months of follow-up, significant improvement was seen in mean keratometry measurements, corneal spherical aberrations, Trefoil, and COMA. No significant complication was observed.

Conclusions:

Astigmatism, mean keratometry, corneal thickness, corneal spherical aberrations and the whole summary of aberration decreased. TG-TPRK with MMC is a good alternative for correcting post-RK cases with irregular astigmatism with elevated higher-order aberrations.
