TitleLasik for myopia and astigmatism with ZEISS MEL 80 excimer and visumax femtosecond laser
PurposeTo study the efficacy of myopic excimer laser assisted in situ keratomileusis (LASIK) using the Zeiss MEL 80 excimer laser in association with the Zeiss Visumax femtosecond laser, with a follow-up up to 12 months.
MethodsDesign: Retrospective case study.
Participants: Patients with different degrees of myopia and astigmatism treated with LASIK.
Technique: The flap was made with the Zeiss Visumax femtosecond laser . Ablations were performed with the Zeiss MEL 80 excimer laser.
Analysis: Data of 1,3, 6 and 12 months follow up were reviewed retrospectively. A questionnaire was sent to the patients to assess subjective satisfaction and side effects.
Main outcome measures: uncorrected distance visual acuity (UDVA), remaining refraction error (RE) in spherical equivalent, safety of the procedure expressed in change in lines of corrected distance visual acuity (CDVA).
ResultsThe preliminary results show a mean RE of -0,04 D, -0,12 D, -0,11 D and -0,1 D after a follow up of 1, 3, 6 and 12 months respectively. The UDVA was 20/16 or better in 29% of patients, 20/20 or better in 83% of patients and 20/25 or better in 100% of the cases after a follow up of 12 months. The preliminary safety results show an unchanged CDVA in 54% of patients. None of the patients had a loss of lines in CDVA after a follow-up of 1 year. 33% gained 1 line and 13% gained 2 lines of CDVA, resulting in a safety index of 1.13 after 12 months follow up. Other results of remaining astigmatism, accuracy, predictability, stability and subjective satisfaction will also be shown for the different follow up periods.
ConclusionThis study illustrates the accuracy of lasik for myopia and astigmatism with Zeiss MEL 80 exceimer and visumax femtosecond laser.
