Filter by:Laser Insitu keratomileusis (LASIK) has become the most popular procedure for refractive error correction. Lasik flap creation is the first and critical step during LASIK surgery because of its consensual effect on a residual stromal bed, corneal biomechanics, and hence the future risk of ectasia⁴.In the current study, we compared the Visumax FSL flap thickness predictability, accuracy, and variability with the flap created by single-use Moria SBK microkeratome.
The study will compare the short-term clinical performance and wearer and practitioner acceptability of a new-to-market spherical daily disposable (DD) hydrogel soft contact lens to a currently marketed spherical DD hydrogel soft contact lens.
To investigate the relationship between axis length (AL) and refractive error. eyes of low hyperopia to emmetropia subjects, comprising eyes with moderate to high myopia (-11.00D ≤ SE ≤ -4.00D) were analyzed in this cross-sectional study. Cycloplegic refractive error was measured with the autorefractor, AL was measured with the IOL master. Association between AL and refractive error were evaluated by linear regression analysis. The mean of AL and its correlation with SE, sex, and age were evaluated.
LASIK is a refractive surgery technique widely used in France. Postoperatively, the classic treatment after LASIK consists of instilling drops to reduce dry eyes. REPADROP® is an innovative eye drops stimulating corneal innervation. To date no study has quantified the improvement in dry eye syndrome and thus the quality of life of patients using REPADROP®.
The primary objective of this study is to evaluate the overall clinical performance of an investigational silicone hydrogel contact lens over 2 weeks of daily wear.
Primary objective of this study was to compare the efficacy of premium monovision with Restor and Panoptix, against other prevalent monovision techniques and against bilateral Panoptix implantation in a sample of patients following lens-extraction surgery.
Primary objective of our study is to develop and validate an internet-based digital near and intermediate-vision reading test in the greek language.
This is a prospective, comparative, randomized, controlled, open-label, single-surgeon, single-center PMCF clinical study whereby presbyopic patients undergoing refractive surgery will receive a SUPRACOR treatment for the correction in the non-dominant eye and a PROSCAN refractive treatment in the dominant eye to correct for ametropia. The participants will be randomized to either a SUPRACOR regular (100%) or SUPRACOR strong (130%) treatment with a 1:1 ratio.
The primary objective of this study is to evaluate the overall performance of an investigational silicone hydrogel lens when compared to ACUVUE OASYS® with HYDRACLEAR® PLUS (AOHP).
The primary objective of this study is to evaluate the overall performance of PRECISION1 contact lenses when compared to Clariti 1-Day contact lenses.
