Safety and Efficacy of a New Transepithelial Photorefractive Keratectomy Treatment
AmetropiaThis is a prospective, comparative, randomized, controlled, single-blind, single-surgeon, single-center PMCF clinical study whereby participants undergoing refractive surgery for correction of ametropia will receive a transepithelial PRK (tPRK) and conventional PRK treatment in the contralateral eye. To avoid bias in the clinical outcomes, the two PRK treatment options are randomized to the eyes of the patients based on ocular dominance. In addition, a 1:1 randomization is applied within the tPRK group to eyes with and without end-treatment laser polishing. Both procedures, standard PRK and tPRK, are performed in a one-step procedure. The main difference between the procedures is, that in conventional PRK, the epithelium will be removed using alcohol, whereas in tPRK procedures, the epithelium will be removed by laser ablation.
A Comparative Study of TECNIS Symfony Plus IOL and a Trifocal IOL
CataractRefractive ErrorThis is a multicenter, prospective, randomized, subject- and evaluator-masked, bilateral-implant study conducted at up to 15 sites worldwide. A total of up to 280 subjects will be randomized in a 1:1 ratio for implantation with either the TECNIS Symfony plus IOL Model ZHR00V or the Trifocal IOL. This will ensure that data from at least 100 subjects in the TECNIS Symfony plus lens group and at least 100 subjects in the Trifocal lens group will be available for analysis at the 6-month follow-up timepoint. All subjects will be followed for up to 6 months postoperative.
Safety and Efficacy Study to Evaluate the Treatment of Both Near and Distance Vision in a Simultaneous...
MyopiaHyperopia2 moreBy using a new software two consecutive laser treatments have been combined to correct the distance vision and to provide a near vision component in addition to the first treatment. This study will help us to answer 2 questions: How accurately this combined technique corrects distance and near vision Whether the correction is adequate to remove the complete need for supplementary near spectacles
