Optimized and wavefront guided corneal refractive surgery using the Carl Zeiss Meditec platform: the WASCA aberrometer, CRS-Master, and MEL80 excimer laser

Comparison of Short-Term Refractive Surgery Outcomes after Wavefront-Guided versus Non-Wavefront-Guided LASIK

“…Efficacy of the surgery was good in the 3 evaluated groups, with 0.0logMAR (≈20/20) UDVA achieved in more than 90% of eyes. This is consistent with the results of previous series comparing the visual performance after LASIK surgery with different laser platforms using WFG and aspheric optimized ablation profiles (4, 14-21). The efficacy of LASIK treatment was found to be slightly better with the WFG ablation profile compared to the aspheric optimized ablation profile (WF-optimized LASIK).…”

Corneal wavefront–guided enhancement for high levels of corneal coma aberration after laser in situ keratomileusis

“…[23][24][25][26][27][28] In addition, eye-tracker systems have been incorporated into new laser platforms for better control of fixation and to prevent the induction of coma-like aberrations. 29 Furthermore, software has been developed that calculates ablation profiles to treat different types of HOAs in complicated cases of keratorefractive surgery or in cases in which refractive surgery was performed using older ablation profiles.…”

Resultados refracionais do retratamento de LASIK com ablação personalizada versus ablação convencional

“…Planoscan foram estatisticamente equivalentes quanto à acuidade visual de alto contraste corrigida e não-corrigida, perda/ ganho de linhas da melhor acuidade visual corrigida, segurança e eficácia e porcentagem de olhos próximos à emetropia. Os estudos comparativos dos resultados da ablação personalizada e convencional para cirurgia de LASIK primária também não encontraram diferença estatística em relação à acuidade visual de alto contraste não-corrigida (11)(12)(13)(14)(15) . Este resultado já poderia ser esperado, pois já está bem demonstrado que a acuidade visual de alto contrate não é um parâmetro sensível de qualidade visual (16) .…”
