Title | Lasik for myopia and astigmatism with ZEISS MEL 80 excimer and visumax femtosecond laser |
Purpose | To 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. |
Methods | Design: 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). |
Results | The 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. |
Conclusion | This study illustrates the accuracy of lasik for myopia and astigmatism with Zeiss MEL 80 exceimer and visumax femtosecond laser. |
