Abstract Details

Purpose:

To assess the efficacy, predictability, and stability of Trans Photorefractive keratectomy (TPRK) on normal untreated eyes with a preoperative best corrected visual acuity (BCVA) of 20/20.

Setting:

Veni-Vidi Eye Center, Istanbul, Turkey

Methods:

This was a retrospective, non-randomized, and single arm study evaluating the outcomes of TPRK in eyes with a preoperative BCVA of 20/20. We included 68 eyes of 34 patients who presented to our clinic and were followed for six months postoperatively. All eyes underwent treatment using the Schwind Amaris 1050 RS by SCHWIND eye-tech-solutions (Kleinostheim, Germany). Refractive, topographic and wavefront Outcomes were analysed.

Results:

The mean preoperative sphere, cylinder, spherical equivalent (SE) values were -2.67 ± 1.4 dioptres (D),-1.25 ± 1.36 D, and -3.34 ± 1.34 D. On month six they were -0.04 ± 0.48, -0.3 ± 0.4, and -0.24 ± 0.42 D, (p1,2,3<0.001) and 96% of eyes had a UCVA of 20/20. Pre and post operative mean K values were 43.73 ± 1.60 D, 41.16 ± 1.86 D  (p<0.001). Pre operative high order, spheric and coma aberrations at 6 mm corneal wavefront maps were 0.31± 0.12, 0.17± 0.07, 0.20 ± 0.10. Post operative values were 0.43± 0.17, 0.21 ± 0.13, 0.20 ± 0.12.

Conclusions:

Our study demonstrates good efficacy, predictability, and stability of eyes undergoing TPRK with a follow-up of six months.
