Abstract

Purpose: : To asses patient preference and compare the short term visual outcomes of ReLEx vs conventional femtosecond LASIK for myopia and myopic astigmatism.

Methods: : Prospective interventional study . Consecutiive patients with myopia and myopic astigmatism in which the spherical equivalent between eyes was less than 1.00 D. The right eye of each patient was assigned to refractive lenticule extraction and the left to conventional LASIK using the Visumax 500 Khz and the Mel 80 excimer laser respectively ( Carl Zeiss Meditec.) Follow up was done at day 1, 1 week, 1 month and 3 months. At the 1 month interval an independent blind questionare was applied over the telephone to assess patient preference. Statiscal analysis was done using the SPSS v.13.

Results: : 20 eyes of 10 consecutive patients. There were no statiscally significant differences in the refractive status (sphere, cylinder and defocus) of right and left eyes (r = 0.91 , p = .54) . Mean preop spherical equivalent was -3.68 +- 1.40 D and -3.61 +- 1.58 for the FlEx and LASIK groups respectively. The difference in post op uncorrected visual acuity at 1 month was not statiscally significant (p=0.54) with 50% of eyes achieving 20/20 or better and 90% 20/40 or better in both groups. 70% of eyes were with in 1.00 D of emmetropia. No eyes lost more than 2 lines. Questionare: 50% of patients stated they see better with ReLEX, 70% were more comfortable during the surgery and would recommend having ReLEX over conventional LASIK for the correction of myopia and myopic astigmatism

Conclusions: : ReLEx is effective and safe as conventional femto LASIK for the correction of myopia and myopic astigmatism. Patient comfort may be better with this new technology.
