Abstract Details


To compare the 3 months visual and refractive outcomes using FS200®(Alcon) and FEMTO LDV®(Ziemer Ophthalmic Systems, Port, Switzerland) planar femtosecond platforms and the Hansatome® (Bausch & Lomb) mechanical microkeratome, in a myopic population younger than 40 years old with preoperative best corrected distance visual acuity (BCDVA) ≥1 (decimal), when used in conjunction with the Allegretto® (WaveLight Laser Technologie AG) excimer laser.


Clínica Novovisión, Madrid, Spain. Clínica Rementería, Madrid, Spain. Hospital Universitario Príncipe de Asturias, Alcalá de Henares, Madrid, Spain.


This is a retrospective, observational cohort study, that included 417 consecutive eyes divided in three groups; 202 eyes treated with the FS200 (F) were compared to 112 refraction-matched eyes treated with FEMTO LDV (Z) and with 98 refraction-matched eyes treated with Hansatome (H). All surgeries were performed by the same surgeon (MGG). Uncorrected distance visual acuity (UDVA), (BCDVA) and refractive results were evaluated 1 day, 1 week, 1 and 3 months after surgery. The visual and refractive results were compared with a factorial ANOVA test.


At one and seven day post-op visits, UDVA was found significantly lower in F than Z and H groups (0,95±0,17 vs 1,08±0,14 vs 1,01±0,14) (p=0,0001), (0,94±0,17 vs 1,13±0,12 vs 1,07±0,18) (p=0,0001), respectively. No significant difference in the UDVA was found at the one and the three month post-op visits. At three month post-op visit, the safety index (1,04±0,20 vs 1,00±0,09 vs 0,95±0,09) (P=0,0001) and the residual sphere (-0,07±0,18 vs 0,02±0,14 vs 0,005±0,14) (P=0,0001) were found to be significantly different between groups, whereas no significant differences were found in either the BCDVA, the residual cylinder or the efficacy index.


Myopia correction is safe and effective when is performed with FS200®, Femto LDV® and Hansatome® in combination with Allegretto® excimer laser. In fact, we found equal visual results in all groups at the three-month follow up visit. Nevertheless, we observed a slightly slower visual recovery in FS200® group.
