Abstract Details

Purpose:

Evaluation of safety, efficacy in a contralateral eye comparison of topography modified treatment refraction (TMR) to standard.

Setting:

LaserVision.gr Clinical and Research Eye Institute, Athens, Greece

Methods:

Group A treated with TMR and contralateral eye with the standard clinical refraction (Group B). 50 cases (100 eyes) were evaluated for: perioperative acuity, refraction (RE), topography, tomography, wavefront analysis, pupillometry and contrast sensitivity for at least 12-months.

Results:

Mean values: RE-5.5D and -1.75D astigmatism. Group A vs. Group B respectively: UDVA improved from 20/200 to 20/16 vs. 20/20. Postoperative CDVA 20/13.5 and 20/20. 1 line vision gained: 55,6% vs. 27.8%; 2 lines of vision gained: 11.1% vs. 5,6%. Refractive astigmatism: 88.3% up to 0.5 Diopters vs. 44.4%. Contrast sensitivity was superior to pre-op in Group A only. All differences were statistically significant.

Conclusions:

TMR LASIK may offer superior outcomes in topography-guided myopic LASIK. These findings may change the current clinical paradigm of the optimal subjective refraction utilized in laser vision correction.
