Abstract

Abstract: : Purpose: To evaluate the safety and efficacy of topography–guided LASIK enhancements. Methods: Peri–operative: refraction, UCVA, BCSVA, cornea asphericity (Q value), and contrast sensitivity (CS) were evaluated in 17 symptomatic consecutive eyes with 6.5 months follow–up. Topography guided LASIK enhancement using the Wavelight Allegretto system was chosen in these patients to correct the small and decentered optical zones, as well as their vision quality problems (glare, haloes, loss of contrast sensitivity and night vision difficulties). Results: Refractive error: –3.50D (plano to –5.50) improved to –0.65 (plano to –2.00), cylinder: –3.75D (–1.25 to –4.75) improved to –0.50. UCVA improved from 20/200 to 20/35. BSCVA from 20/50 improved to 20/18. Q value improved from +0.7 to +0.1. CS improved by 70%. There was one loss of BSCVA of 2 lines. Conclusions: Topography guided LASIK enhancement appears to be a safe and effective option. It requires little central tissue removal and should be viewed as a possible 2 step procedure in regard to spherical adjustment.
